Picture of No More Roaches
I have wanted to write this Instructable for a long time but could not bear the thought of a photo of a roach. I found a plastic one; problem solved. I think you get the idea from that sentence that I am just a little bit, somewhat, sort of, come to think of it, mildly, TERRIFIED of roaches. This is the story of how I got rid of the roaches in my home and they have stayed gone for 10 months now after just the initial treatment.

Step 1: What you will need

Picture of What you will need
maple syrup pour.jpg
Boric acid powder*
Karo syrup - you may substitute honey or maple syrup or pancake syrup
Rice flour - you may substitute any flour you have on hand
1 Popsicle stick
1 Mixing bowl

Amounts as follows:
2 parts Boric acid
1 part rice flour
enough Karo syrup to make a peanut butter like consistency mixture

Important note: Boric acid powder is not something you want to inhale (get into your eyes or swallow) so mix this up outside. Wear a dust mask too until it is mixed up. It has no odor.

For a 2800 square foot home with 4 bathrooms, I mixed 2 cups of boric acid with 1 cup rice powder and about 3/4 cup of Karo syrup. I used a plastic bowl to mix in and stuck the bowl and left over bait up into the attic/crawl space when I was done baiting.

*(available in hardware stores in the US as "Roach Prufe" (this was the only way I was able to buy it, the canister is 98% boric acid and 2% blue coloring).

Step 2: What my kitchen used to look like

Picture of What my kitchen used to look like
For every roach you see there are probably 100 hiding in the walls. If you see a roach in the daytime it means you have such an infestation that they are crowding each other out of their hiding places. Did I say gross?

No more roaches!
FoxysMyGirl5 months ago

I had a problem with roaches last year following a roof leak. It grossed me out. It was the big kind that are supposed to live outdoors. They found a way into my attic and it was terrifying to me since I am a big chicken about roaches, nothing else only roaches. I saw this recipe and didn't want to make anything that would be a bait and attract more but then I thought about how they would take it to their nests that I wouldn't even know how to find in order to spray or treat them. I did it and it has been Miraculous!!! Thank you!! No roaches, not one in an entire year! It took less then 2 weeks and even in the two week period I was seeing fewer and fewer. I didn't have a lot in my house but I would see a couple per week and I knew there was a lot in the attic. Had I not used this recipe I am sure I would have seen more and more and been disgusted every time. I saw a bug on my porch last night so I am making the recipe again today. He may have just been from the flower beds but I don't care, it is not starting again here. Thank you very much for taking the time to post this amazing information!!

Thank you so much for taking the time to write. I know it works, that's why I posted it so many years ago. I wish more people would simply do it. I mean just read the ible and follow the instructions.
can i use regular floor and regular syrup
Ninzerbean (author)  lisa.myles.1042 months ago

Yes, it says so in the 'ible, you just have to read the whole thing.

i have the stuff is it ok to use it

Hi, first of all just want to thank you for your continued attention on this forum - it's been 5 years and you're still here! Stumbled upon this article (actually, I sifted through countless links after re-wording questions in the Google search bar) and spent the last hour reading your instructions and comments. I live in Australia down in Sydney and moved into my unit about a year and a half ago - no pest problems up until about the last two months. One crawled on my dad while he was sleeping. I was so disgusted but couldn't wrap my thick head around the fact that there were probably 30 more for every one where we couldn't see. I wasn't surprised my dad encountered two in his room because of his eating habits - he leaves empty cans and food wrappings on his desk overnight and one time left a scraped-clean half a melon in his room. Like you, I am so repulsed by these critters I can't even stand seeing an image of them (which is why I've been so stressed about looking at article after article). As disgusting as it may sound, I've spotted the droppings of these American roaches in the drawer of my kitchen utensils (I have to wash everything I use again before I eat now), along the sill of my kitchen window (from in the inside) and alongside the kitchen wall next to the fridge. After my dad told me about his experience I rushed to purchase some roach baits which I've placed in the kitchen next to the fridge, between the fridge and the counter, next to the oven, and in corners of the kitchen overall. I've gotten my dad to help clean the counter tops and rid of any potential food, wipe down the stove top and microwave etc. It's been a little over a week and I can't tell if there has been any progress. My father spotted one on the stove top today that actually raced under and into the oven (we didn't even know they were connected) after he turned the lights on. Frankly speaking, my major anxiety is not helping me cope with this well, the problem's been on my mind ever since I placed the baits around. It's gotten to the point that I have to wait a moment after turning on the kitchen light in the evening before entering, if I absolutely must, and I shamefully admit it has reduced me to tears a few times when I think about it. My extreme fear heightens every time there's been a sighting. I know I can't call an exterminator for advice because my dad always thinks I'm over dramatic and obviously, exterminators = $$$. I would spend as much money on it as possible if it means getting rid of these critters, but I'm only 16! When I mentioned to him about making a stop at the local Bunnings store to purchase some boric acid powder just now, he was pretty annoyed and said the commercial roach baits were enough. Clearly I have no choice but to do this myself. Tomorrow I'll be getting all the ingredients you've listed above and start cracking down on this widely acclaimed remedy. I really, really, really hope it will work. I'm pretty sure I can't place the bait in the oven because of the poison and neither the kitchen drawers, so will smearing it behind the sink tap suffice? And the 4cm space between my fridge and the counter? And due to my problematic near-phobia state, can I only bait it in the kitchen? I really do not want to attract any to my room, living room or bathroom etc. I'm sorry for the really lengthy comment (probably the longest to date), and will be super grateful if you leave a reply. Thank you so much!

Oh Dear KarenZ1,
I wish I was there to help you, I totally understand the tears. Yesterday I found a tick on my dog Otter that was so big I almost started to cry, I was so grossed out that I called a neighbor who told me to bring the poor little OtterBean to her and she removed it. I was dancing all over her kitchen like a total spaz freaking out. I had to go home and strip the bed, wash everything and now I don't even want to pet him. How sad is that?

So, anyway, the stuff is not poisonous to you, you can safely put it in your silverware drawer, just pull the drawer out as far as possible or go up from the underneath of it and scrap some bait on the back.

But, and this is the big but, you have to get your dad on board, he has to read this 'ible, he won't be the first dad to do so. He has to help you bait the whole house or it won't work. The stuff you are using probably kills roaches, you don't want to kill them as much as you want them to bring some bait back to their home-base, and then some will die by eating it but the important part is that they then tell each other NOT to go back to your house - because the food there is killing them. They work as a colony, not that much different than bees. But I don't want to get into a whole thing about bees and the definition of colony again on here. This is not common belief about roaches - it's my belief. Think about the multi-billion dollar a year pest control product market. They do not want to solve the problem. That would put them out of business. So anyway, point being, you HAVE to involve your dad, I don't want you to be taking the switch plate covers off the walls and he has to not leave food stuff in his room.

You have to bait your whole house for this to work, the bait will not attract roaches to your room, they live inside of the walls, that is where you are putting the bait, and around water, damp, warm, dark, high up etc. places.

Keep in touch. Be strong, be brave. Find someone who is not afraid to help you if your dad won't. Tell him I told him he HAS to help you.

Read the 'ible again and again, click on all the photos, read the comments, don't put the bait inside the oven but instead in any cracks or small places underneath the oven. Vacuum every day. This will get really old, the vacuuming, but it does work, you will see results in only a few days.

Try getting that expanding foam to plug up any open areas underneath the sinks or where pipes come into the house - but don't get it in your hair or on your hands or clothes, and plan where you are going to use it 'cause you can't use it again once it's opened.

Once it is mixed, do we put bowls of it near all the sinks, toilets, wash tubs, and all water sources? Next to the kitchen sink or under it or both? How does this get rid of the roaches?

Ninzerbean (author)  coll285013 hours ago

That is what the popsicle stick is for. In step #7 you can even see it in my fingers, applying the paste to the various places. How the paste works is explained elsewhere in the 'ible.

Thank you.. I see now I didn't know I was missing so much of your post.
Now that I see all 8 steps, its clear. Great post. Thanks so much.

I think my last post got lost. Thank you for saving me money.I'm picking up 99% boric acid in home depot today (Sunday). Will be buying a light weight vacuum cleaner.This week,in your opinion which is better bag or bagless?
Best for the coming year and thank you for the tips.
Ninzerbean (author)  charko3 days ago
I would think a bag would be stronger suction but I have no idea. I have a central vac. I'm sorry not to be able to help here. I am a believer that what ever one has the most power would be best. Maybe read reviews?
charko5 days ago
Thank you for saving me money. Did not get a chance to go to home depot today. Will go tomorrow for the boric acid. they have something called hot shot max attrax. with 99% boric acid.on line they have something called jt eaton also with 99% boric acid but thats on line only. Is boric acid boric acid or is the roach pruff the only one you recomend?
Ninzerbean (author)  charko5 days ago
Any product with a high percentage of boric acid will do. I have not heard from anyone that they were able to get it at Home Depot. Online may be different though. Roach Proof was all that I could find, it was 98% boric acid. It's just a brand name: any boric acid will be great. Be sure not to confuse it with borax, not the same and won't do any good, well not for roaches anyway.

Tried,Ortho,raid,bug barier,bug stop and raid kill on contact. stuff burns my lungs, and have to hang over an open window until i can breath again. Exterminator wants $$$ and im a senior. said it may work if not he wld come back for more bombs and have to stay away for at least 2 hrs each time. Will be going to dollar store for mixing bowls and pastic containers. Any ideas on how to keep them away from my coffee pot that is always full?

Ninzerbean (author)  charko5 days ago
See step 7. They like water, heat, dark. Bait where it is wet, dark and warm. Why do you need plastic mixing bowls? Any bowl to mix in is fine, wash it and use it for food. It's just a place to mix in.
charko6 days ago

Has anyone ever made up a bowl and stuck it in the bathroom vent space?

mlbishop6012 days ago

I am 54 and have NEVER shared my house with roaches.... until now !!!

I bought all the stuff from Walmart for roaches and even used straight Boric Acid. I have sprayed TempoSC, Permethrin, and Demon... and I still have them, not near as bad, but they are still here.. I am going to try this tomorrow...

Ninzerbean (author)  mlbishop6012 days ago
I'm convinced that just killing them is not good enough, you have to convince them to leave your place by using this bait which they bring back to the colony, some die and then the survivors tell the others.

I am severely allergic to insecticides and ended up here in roach HEAVEN! My long term plan is to move home ( Talkeetna Alaska), but until then I'll try your method. I will also bait bait and bomb the shipping container used for shipping our household. NO UNAUTHORIZED PETS for me! Thank you.
Ninzerbean (author)  Susitna14 days ago
Roach heaven - that's so funny. Appliances and stuff that gets plugged in is where they like to live.
I just killed the biggest roach I have ever seen ...COMING RIGHT AT ME! ACK!!! Do you have to use RICE flour? Will it be just as good to use a cheap pancake syrup? Please help! P.S. What can you do if you are terrified of them getting up on your bed and falling from the ceiling?
Thank you!
Sorry, I just saw that you answered about the flour. I thought I did read the entire thing but, shoot, I don't mind reading it again! Thank you so very much for posting this! My mom just died 2 weeks ago and I can't handle anything else right now....especially roaches. This is a new apartment for us and it looks as though there us an attic space right out our door as if it may just run the length of the breeze way....I may ask the maintenance guy to put some up there..
Can I ask you a non-related question? A friend of mine said I "had" to start a blog because it would help so many people....could you tell me how you did this?
Ninzerbean (author)  bonloveslife14 days ago
Dear bonloveslife, I'm so sorry about your mom, I can understand how fragile you must be right now. Maybe it will help you put roaches in perspective, as they are not anywhere as terrible as losing your mom.
I don't know much about writing a blog, I wish I had done that years ago about moving north to find the south but anyway.... Do you think that this 'ible is a blog? It's not. It's an instructable, this is the best place on the internet - and you found it! Instructables! Wander around, become a pro-member, share, go on the forums, write an 'ible (short for instructable) about how to deal with your mom's passing or whatever you friend wants you to write about but if you really want to do a blog, which is really set up for that - check out Square Space. I love their clean format and themes all done for you. Good luck to you.

Im thinking that when i moved to my new apartment that i took some with me but not sure how because i searched everything i think they were most likely in my sons toys i didnt have the heart to throw away all of his toys because i cant replace them right away. I threw away most i kept the ones i thought were okay. But they hitched a ride and now Im wondering should i just toss everything? I hardly kept anything just pots , pans, clothes that were washed at laundromat, toys, and my dyson vacuum that i really love and hate to throw out. But its possible they are in there. I keep it outside in a heavy duty bag. And I treated the new apartment when i moved in two weeks ago with combat no results from what i can see. And I just treated with your mixture two days ago and seen about 6 today and a few yesterday. Theres no exact spot i can pin point them except the baseboards. Sorry for the double post the comment section here is a little funky i couldnt tell if it actually post or not.
Jenni-014 days ago
I tried making your mixture i didnt have any regular flour on hand so I used pancake mix hopefully that doesnt ruin the whole thing but it does have flour in it. Anyway I placed it everywhere I could think of I have a small apartment so it didnt take long I did this two days ago. Ive been seeing more lately unfortunately I have no idea where they are coming from but there is a little gap underneath my baseboards and seen that a few hang out there there is bait there now. I havent seen any dead ones and ive put combat gel out 2 weeks ago. Im getting discouraged are they like immortal or something? I'll be back to update in a few more days hopefully Ive seen some improvement. Any advice on what I can be doing other than cleaning like a crazy woman because im doing that lol
RachelS714 days ago

FOGGERS/BOMBS DO NOT WORK. DON"T WASTE YOUR MONEY. IT DOESN"T MATTER WHAT BRAND. And the roaches you think are dead, they are still alive. I was scared to pick them up so I waited a few days till I could find someone who wasn't scared. By that time, they legs were moving and they were upside down. I decided to spray before moving into my new place since it seemed like the renters before me weren't so clean. I would see them even around the house a week and so later even though it is supposed to keep them away for about 3 months.. I did find a spray I used around my house that actually worked better. I spray often just in case the water wares it away.

mizzdawn15 days ago
I seen a few roaches a week ago in my kitchen cabinet I bombed about a week ago I put one bomb in every room with door closed. When I came home after 6 hours I seen a few dead.. I cleaned them up vacuumed threw the vacuum bag away immidiatly a few days later I have been seeing them every where little one big ones dark ones light ones... I also noticed the fleas had got worse too?? I woke up today with one of them on me and that's it for me either I burn this place down or I fix it FAST..... I'm thinking about using this recipe and bombing again? Any suggestions. What's the best bomb/fogger? I want them gone asap!!!
Ninzerbean (author)  mizzdawn15 days ago
That is a good question about which fogger is the best. I really don't know as I have never had to use one. But since you have already done this, I think you need to be thinking about where they might be living - this is kind of gross, but you will have to start looking around inside, around and behind all of your appliances and game consoles and/or audio equipment.

Because it is getting cold outside they are probably moving inside and are more active than a month ago, that is why you are seeing so many right now. The same thing happens after a big rain. But until you find out where they are living in your place the fogging will not do much. You should read the comments: there is a ton of help there.

You will have to really get into the habit of vacuuming every day (until you don't see any roaches at all), getting rid of all cardboard, cleaning everything as if you were getting ready for your Italian mother-in-law to visit you and her first born son.

Once everything is perfect and seems under control, then bait. Or you can bait now of course too, but you still need to find out why they are at your place, what they are eating, where they are living. Normally I would not give advice like this but because you fogged each room and it really did no good there must be a reason. The bait in my recipe will keep you roach free for years but you need to still be proactive in the very beginning, meaning that you have to do some work yourself to get them under control.

Hope that gets you off to a good start, keep us posted on your progress.

Is 63% boric acid fine ?
Ninzerbean (author)  Ymv1315 days ago
I would not think so, there might be other stuff in there that may counteract what you are adding or maybe even kill before it can be taken back to the colony.

But then again maybe someone has simply made a version of my recipe and is marketing that. Why don't you try it and let us know if it works and what it's called.

I'm living in a townhouse and for the past 8 months my home is being taken over by roaches... I have tried everything bombs, Raid, and Ortho Home Defense and none of them seem to work, so tonight I'm mixing up this stuff on the page to see if this will help me.,..however I have one question where all can I put the mix and will it cause any damage to the walls? Please help

Thank you

Ninzerbean (author)  VeraA115 days ago
See step #7. It won't hurt your walls, or painted surfaces but you won't be putting it anywhere that would matter anyway. Reading the comments will help as well.

Hey I have a bad roach problem and I am going to actually try this. I hate them and I feel like they are taking over my house . One question tho .. this is an old apartment with spaces in the corners and along my apartment walls. I feel they travel through there as well . I want to cover it up . Do you think like plaster or roach gel would do the trick ?
Ninzerbean (author)  zymirmommy17 days ago
Caulk would do the trick to seal up those gaps.

I have a problem with roaches here at my apartment and I have seen testimonies on here but I have no idea where to go by the roach prufe some one can you please help with any idea hardware stores or etc because almost everywhere I call they have no clue where I can find it

It seems easiest to buy online. Googling it turns up a lot of resources.
Jenni-017 days ago
Hello Im going to try out your mixture. I recently moved out of my apartment and into a new one because the management there wouldn't hire an exterminator. It was really infested there and I took precautions when packing but those little ******* are tough and resourceful. Anyway I took some along with me I seen about 20 almost all babies and Im disgusted.. I put out gel bait everywhere and puffed boric acid along baseboards and under sinks. Im really scared that the will start making themselves at home and ugh start multiplying so Im trying to take care of this problem quickly. Im going to try this out and let you know how it goes. Please say somes prayers guys! I cant live like that again.

If I make this mixture and put it around the house, will it harm my cats? I don't know if they would try to eat it and I can always keep them in one room until the mixture gets hard.

Ninzerbean (author)  ezzyscofield18 days ago
See step #7, you are not really going to be putting it in any areas that cats can get to. Even so, I can not imagine a cat wanting to eat this. I have to ask this, being that I receive so many questions like yours - are you reading the whole 'ible, all 8 steps? Maybe I need to edit the 'ible so that people know to look at all the steps. If your cat can take the screws off of an outlet cover... well, I really don't know what to say, except that roaches are the least of your problems.

I'm about to use your method in my apartment. You seem pretty confident so hey I believe you. I have a 6 month old and I'm worried that one day she'll find one and pick it up and eat it...So yeah definitely desperate for anything... Thank you and ill get back in to weeks to let you know how it turned out

Ninzerbean (author)  BerghandyLeigh20 days ago

Hey BerghandyLeigh, how is it going? Good or bad I want to know.

Ninzerbean (author)  BerghandyLeigh2 months ago

Please do, share whatever, good or bad. We can all learn from each other.

hello, so I have roaches! I've used teremix, orkin, home traps, raid,hotspot gel...NOTHING HAS EVER WORKED. At one point I didn't see any got comfortable and started leaving dishes in the sink over night....bad idea they came back. Retreated with the diatomaceous earth didn't see many for a while. I felt like I was finally winning the war. Recently I went on vacation and they moved in full force...It was so gross. So i cleaned out that area threw away everything I thought I Got rid of the "source" stopped seeing them as much. 3 days ago we decided to bomb the house to "kill the rest" bad idea bc now I'm seeing them at night (not 7-8 at night which I kill with raid or my shoe) All over thebed room door and bathroom door. Could it be that the bomb brought more of them out? Bc they were never out like that before. I feel like the bomb was a bad idea:-{

Anywhoo. I'm going the make your mixture in the morning bc me sharing my house with bugs of any sort isn't going to fly. My skin is crawling as we speak talking about those little suckas. Thanks for the advise...I'll be back with a success story.

SN can i use Hotspot boric acid or will I need to get a certain brand?

Ninzerbean (author)  80sbaby4ever1 month ago
I don't think bombing was a bad idea - I think you are seeing them at night because when you were seeing them in the daytime it was from overcrowding. I don't know if Hotspot Boric acid will work - what you want is just boric acid, look at the ingredients and see if the boric acid amount is really most of it. Stay in touch. This is going to work. I love leaving my dishes in the sink overnight.

I just purchased some Hotspot Boric Acid. I read the information on the bottle and it said 99% Boric acid. So I am assuming it will work.

Ninzerbean (author)  marvel.knight.320 days ago

Assume away. I will be assuming away vicariously with you. Really though, it sounds like just the right product.

I never saw them in the day time only at night. But I'm going to go to Home Depot today to get the boric acid. Thanks for the reply

I did half a cup of boric acid, 1/4 cup of flour and added a little powdered sugar and then the then the syrup. Do you think that the sugar would be okay? I found them in mine so i decided to add some haha
Are u still taking questions?
Ninzerbean (author)  myeasha.gregory27 days ago

Almost every day. What's your other one?

Do I just put the bowl in the kitchen and leave it there? Do I have to make a new mixture every day? I have 2 kids (5 years and 14 months) are they safe? I also live in an apt...this is grossing me the heck out. I have seen them in my kitchen, freezer, dishwasher, bathroom...

There are 8 steps to the 'ible, see step 7. I think you are just on the first page.

WILL it work for german (small)in my apartment .I have used boric acid powder(not bait) in past but this does not work any more .They always come back.Is bait method more effective?

Ninzerbean (author)  asma.rizvi.7981 month ago
The bait is WAY more effective because the powder alone will kill the roach that runs across it but the bait is so that the roach will bring it back to its colony to feed the others and they will die and the ones that don't die will be really upset so they will look for another place to set up house.

And yes, it does work for Germans but it will be more effective if you can find out where they are living in your place. The big ones live outside but Germans live inside and so you have to find out where and dispatch them. They like warm appliances and game players. Electronics are heaven for them.

HI, I have alot of roaches (we seem to have both kinds of roaches) all in my kitchen they seem to be coming from behind the cabinets as they are not set flat against the wall. There is about a half inch space between the wall and cabinets, so its really difficult to put anything between. Last night I prepared the boric acid dough balls. I used 1 part boric acid, 1 part flour and a lil bit of sugar. I placed the lil balls all over the kitchen and house as wel,l where i've seen evidence of roaches. The roaches was attracted to it like it was the best thing they've had in years. However this morning when i walked in the kitchen i seen so many roaches big and small. Way more than usual. Is that normal? Does the boric acid draw them out?

Ninzerbean (author)  CaseyJaye1 month ago
Well according to some people that has been the case, but it seems to just be evidence that is it working. I don't know the reason why, I would only be guessing. This didn't ever happen to me but it may have been because the exterminators (on my first house, the one I was renting) did a big knock-down before they baited. I don't remember that, I'm just guessing.

Keep us posted on how it goes. I suspect it will get better every day from here on out.
TaraT21 month ago

I made this but it became very hard after about 24 hours, is this right?

Ninzerbean (author)  TaraT21 month ago
Yes that is normal. It's good. That way it won't move. But if you didn't get the whole house baited and you have left-over which went hard then it's probably too hard to spread and you will have to make more. If that happens again store it in the fridge (covered) until you can use it all up.

Mines have become hard as well, but the roaches are still on it lol. I guess they like crunchy too lol. On some of the balls they've eaten a hole into them. I'm not seeing as many as this morning. The true test will come tonight at 1am.

cwhitty131 month ago
Great thank you! We are doing it today, I have had Orkin pest control for over a year and they have just gotten worse so I'm hoping this helps!
Ninzerbean (author)  cwhitty131 month ago
Of course they got worse, why else would you be calling them back each month, it's sort of planned ineffectiveness. They would not be in business if they were effective.

But keep us posted so we know how you are doing.

Hello, I just moved into an apartment and it has roaches. They are mainly in the kitchen but I've seen a few in the bathroom and in the living room. When I initially saw them the day after I moved in, I bombed my unit. There were over 2 dozen dead roaches throughout my apartment. Babies and adults. I contacted the management and they said that they would exterminate but they had to wait a week because I had bombed and it would not be effective. During that weeks wait, I continued to kill roaches but I put them in a zip lock bag and took them to the rental office to show them that I mean business and I will not live like this. Naturally they were not happy I did that, but I'm not happy living with roaches. So a week has gone by and they exterminate (or so they said they did) I have no proof. I have been here for 2 weeks and today was the first time I have eaten here because of the roaches. I have no food in the cabinets, only in the freezer and a few items in the fridge. Today I decided to cook a frozen pizza, I opened the freezer and there was a baby roach dead between the cracks (insulation) in the freezer. I turned the oven on and put the pizza in the oven. When I went to check on the pizza there was a roach crawling along side the cabinet. I killed that one. Then when I went to get something from the dish washer there was on crawling inside the dish washer. I couldnt kill that one because he got away. No sooner than I turn back around towards the stove there was another roach crawling up the cabinet. I have never seen that many at one time. I thought I was home free because I only saw one here and there throughout this week, but to see 3 in less than 10 min. Do you think it was because I turned the oven on? I sent an unpleasant email to the rental office saying they need to exterminate again this week. I want to do your bait solution but do you think it will counter whatever the exterminators (if they are actually coming) will do? Also how often should I use the bait solution? I live in an apartment and I don't want them thinking they can travel back and forth to my unit.

If the exterminator came and did not leave a receipt or a card I sort of really doubt anyone came. But more to the point, I LOVE that you are taking the roaches to the rental office - what a brilliant idea!

Obviously the roaches are living inside your oven, and fridge, that is why they started moving when you turned on the heat. They live there because there is warmth in the electronics.

My bait will in no way interfere with what the exterminators do, you can use both. My bait does not need to be done more than once every few years, to be safe you could put it out (it does take a long time to do) once a year. Whenever you buy used electronics know that roaches could be living in them. Read through the comments to see how many strange places that roaches live.

I would suggest meeting your neighbors and getting together on this issue with the landlord. The roaches are in your walls, so everyone must have them. Unless of course they are using my bait.

I can't see all the comments and I'm sure someone has asked this before but how long does it take for this stuff to work? Is it like a week or month or year before they are gone?
It took me about 2.5 weeks for it to work. It actually seemed to get worse the second week and I was losing hope and just started spraying the ones I could see with raid and then one night.....GONE!! I couldn't find any for 4 more days and one night I saw one more roach which I quickly sprayed and I have not seen any now for a week. It works!!! I am so grateful I followed the instructions and I have my kitchen back now.

It does start to work the same day but how fast you will see results I guess depends on how proactive you are in finding a possible nest if you have Germans (that live INSIDE your home), or how bad your infestation is to begin with.

Thanks for telling us your experience. That really helps.

Thank you it may be safer to get rid of the microwave, I haven't needed it this past 2 weeks anyways, my husband will have to adjust, or I'll get a small one down the line if needed, I will update again in a few weeks as to how everything is going!
belma.rueda1 month ago

hi, let me start by saying I have a huge phobia of roaches, so as you can imagine, I have been having a very hard time since I noticed I had this unwelcomed visitors in my home. First it was only the big ones from outside, so i hired a professional exterminator, they came out once a month, the second month I notice a little one, the third time he came out I pointed it out to him and he said they were german roaches, after googling them I almost had a panic attack, seeing how fast the reproduce, and by then thinking i'd have thousands more, so he came out again and did something he called a "flushout" he used a little can to spray the cracks and cervices of cabinets and inside and many came running out, anyways, I thought that was the end of it. But no, now there's more than before, I see maybe one during the daytime, and a couple at night, mostly when i open the cabinets in the kitchen or in the bathroom, I don't walk into my kitchen at night at all, I'm literally afraid.

So yesterday, I made your magic potion exactly as stated, I found 100%boric acid, maple syrup, and flour, I had a limited amount of time, so I only placed it in the kitchen cabinets, drawers, under kitchen appliances, under sink, in the bathroom, and pantry, which is in the hallway, I saw one there, and behind the tv in the living room, i killed one there one time too, and above all doorframes, tomorrow, I will be going through the pantry, throwing away all boxes, storing everything in plastic containers, and baiting throughly again everywhere, but my question is, today, after halfway baiting yesterday, I saw a few very alive ones during the daytime, so does this bait, actually make them come out more before it starts killing them?

Update: so it has been 2 weeks since I used the mixture, applied it everywhere you mentioned in the steps above, and then some extra places, I deep cleaned the house, got rid of a few small appliances, a few others have been in sealed bags in the freezer for 2 weeks now, the microwave has been sitting outside also for 2 weeks, I threw away all cardboard boxes, all my kitchen and pantry items are sealed in plastic bins or ziplock bags including my cutlery and all kitchen utensils! Along with baiting I also dusted (very lightly) the boric acid all over the walls and baseboards, and ceiling, and inside the rest of the electronics, I.e. Tv's, dvd's came consoles etc, I just puffed the powder into the vents.
At first I started to get worried because after the baiting and dusting I started seeing more come out during the day and all hours, and more towards the hallway and one tried to sneak into my bedroom, but after much googling, apparently this is a good thing, since they only come out during the day when it's overcrowded, OR, when there is a stress in the environment, such as the boric acid, now I knew my problem wasn't overcrowding because I had a profesional come out before and he said it wasn't bad, because I noticed in time, so the other option was the stress caused by the boric acid which made perfect sense, specially since they just stood there, when they came out barely walking, or when I would cook they would come out because there was absolutely nothing else for then to eat, so this continued for about 10-12 days or so, the first few days I would see a few and then fewer, it's been 2 days and I haven't seen one! I'm still afraid to open the kitchen cabinets though because I feel like I'm gonna see one there but everything in there is dusted from top to bottom, (yes we've been eating on disposable) when I cook everything gets washed, dryed and put away, and cleaned! I still won't say that I completely got rid of them althought I hope I did, but I will continue to dust and clean! Specially since I told the kids we weren't having a Christmas tree if there were still roaches in the house!
Now I do have a couple of questions though, :)
I only saw a very few dead roaches in the mornings, does this mean that they could only be hiding and not gone like I hoped? Althought the ones that came out that I killed were half dead!
And my microwave has also been dusted inside and out, for 2 weeks as well as been sitting outside where it's kinda cold, would it be safe to be brought back in? I'll still probably give it another week out there if so anyways
And thanks so much I really do hope I have gotten rid of all of them, I will continue to dust just in case but I hope I'm free of roaches!! Oh and it kills the ants too, and the flies!
Ninzerbean (author)  belma.rueda1 month ago
I can only tell you of my experience with an air conditioner. I bagged it up after totally powdering it with boric acid and let it sit outside for two weeks. Totally still infested. I had to have it taken away and had to buy a new one. I don't think it is safe to take apart a microwave. Personally I don't even own one anymore, it's been a year and I don't miss it a bit. But it was only because I could not find room for one in my new kitchen and I think they are ugly. But that's just me.

As to your first question - I just don't know. I'm not a fan of using the dust because it only kills them. They can't take it back to the colony and get the message across that your place is a place to stay away from. They don't eat the powder by its self. It just kills them if they get any on themselves.

And don't believe anything a pest control guy tells you. They are trained to lie like rugs.
Ninzerbean (author)  belma.rueda1 month ago
No, seeing more was just because you are opening up everything and so you just noticed more. I'm sure there are plenty of things in your house to feed them without this bait. I don't mean you are not keeping a clean house but roaches can live on toenail clippings for some crazy amount of time. You need to be diligent about vacuuming and vacuuming and getting rid of cardboard and worst of all you have to actually look for where they are living - this is really hard to do if you are like me and I think you are. You have to pull out the stove, look inside the vents on your microwave, shake your game players (gently) and read all of the comnets to learn more than you ever wanted to know. You need to finish baiting the whole house asap. If you don't think you can knock them down enough I would have fog the place, then again vacuum vacuum etc. It's a war, really. But a war you will win. Get some help though to deal with the fear factor. Keep me posted and good luck, it's a huge effort but it does pay off.
Thank you for replying, I didn't see any when I was baiting, I mean the day after even today 2 days after baiting they're coming out in the daytime, which rarely happened before, they're just running across the floor, which I hope is a good thing meaning they're somehow dying right? Otherwise they wouldn't come out during the day right? I poured the boric acid straight onto the ones I saw so they'd take it back to the nest hopefully!
I forgot to mention on my original post that I had a wood cutting board, sitting behind the sink one day I saw one run under it, so I put it in the sink and turned the hot water on it and they started coming out of the sides of the board (thank goodness I didn't use it) I threw it away, so could that have been a nest?
One more question, sorry, how long after the baiting should I wait to see if if worked? I will be thoroughly baiting, cleaning and throwing out cardboard today, so after that how long should I wait or how would I know it really worked? Before calling a professional again!
Ninzerbean (author)  belma.rueda1 month ago

Hi Belma.rueda, I think you have German roaches. They are harder to get rid of, I was going to tell you again to read the comments but it seems hundreds of them of disappeared! I will contact HQ about getting them back because there is a wealth of info there. Or was. Anyway back to you, the bait works right away and you should see a difference the same day - BUT I think you still have colonies or nests in your house for you to see so many. I think you really might want to fog two times over a few weeks to kill any hatchlings which are not affected by the fog when they are in the egg cases. When I had my terrible infestation the guys did a big knock down with sprays or something, it was so long ago....I can't remember but they came back the next day to bait the house. See with the larger regular roaches that live outside it is easier. But living in your cutting board tells me that there are more that are crowding out others to live in such an openish place. Keep me up to date on how it goes though.

And I don't think (except for killing) that pouring boric acid right on the ones you see will do any good - you want the roaches to bring food back to the nest so they can all eat it and say this is terrible, let's move. It's not so much about killing them as having them relocate. You are sort of working with them. All the comments about the colony behavior are gone, this is now making me rather irratated.

We've used this recipe successfully on several rental Houses we used to manage. Instead of using a liquid such as syrup or honey, we used a few tablespoons of sugar. To get into really tiny cracks or behind cabinets, lightswitches, etc., we used a small plastic syringe (no needle). This works like a charm.

Ninzerbean (author)  audrey.lindsey.7121 month ago
Thank you ever so much for your input - but I don't understand - you are pulling the powder up into the syringe (and then squirting it out)? So no liquid at all? That is great for cracks and crevices and it is a good suggestion to use that AND the sticky bait so it can be stuck to more things on horizontal surfaces.

Everyone will be grateful for your idea.

Well I am about to use your bait for the first time and fingers crossed Im praying it works,but i have a question for you first. My husband and I live in a older model mobilehome with our two toddlers and two teenagers,I know not enough room and nobody wants to clean.I havent had roaches in 10 years and we live about 350 feet from my mother in law who has been dealing with her own german roach problem for some time now,well guess what 3 months ago i saw the first one here. Of course we bombed and bombed , yeah right like that worked, now ive just sprayed down my house with demon wp and a IGR ,noticed a decrease in population, but now they seem desperate for food and especially water. Our mistake was not baiting waywhen we sawthe first one .Now they are in every room the kitchen being the main ,but literally under the coffee table ,do I bait everywhere ive seen them?

Ninzerbean (author) month ago
Try to get the bait in all of the out of sight places you can access, be creative and see all of the photos in step #7. I suspect they may be living in some warm electonics - teenagers = game consoles? Maybe something like that, a DVD player?

So, first of all you have to absolutely clean clean clean so that the ONLY food they can find to eat is the bait you are putting everywhere. Then go work on your mother in law's place. Just to be nice.

To specifically to answer your question, I don't advise baiting where you have seen them but trying to find out where they are living and to deal with that, then bait, and vacuum everyday, get rid of any cardboard. AND make those kids help. Give them a nickel for every roach they kill and have a contest for the biggest one that is killed.

I do think that bombing does work, but I also think they are living somewhere inside. Keep in touch, let me know how it goes.

I live in an apt building and we have them bad. I usually don't see them to often in my apt. but recently I have been under attack at my desk at night. Gross! I'd be typing away on my computer and all of a sudden feel something crawling on my arm. I started noticing them in the desk drawers and cleaned them out. Still haven't found out where they are coming from. I have tried everything and even have my place sprayed monthly. Looks like i will be going to the hardware store to get the good stuff.

Ninzerbean (author)  vbanaszak1 month ago
I would not be surprise if they were not living in some electrical equipment near your desk. They love warm places.

So I started seeing roaches outta nowhere in the apartment I have lived in for some time. I believe they are german cockroaches from the pics i googled (ewwwww kill me now). I followed your instructions word for word even putting the bait behind the light switch covers. I have only seen now dead or dying roaches. I hadn't seen one for days and just saw a dying one in the hallway to the entrance for our apartment(we have seen a lot there). Now I am wondering...are they coming from the apartment building and maybe are just not mainly in my place? If so, how can I ever expect to fix this problem? As I have said I haven't seen any more live ones (except the one dying on its back in the hallway), so I know what you told me to do is working! However, we are moving soon to a beautiful house and we are worried they will follow! any advice? thanks

Ninzerbean (author)  nomore841 month ago
I think that the only way they could follow you is if you brought along some infested electronics things. They love to hide in PS3 players and stuff like that, microwaves, toasters. You just need to be sure there are not any living or hiding in your stuff. Before you even unpack at your new place, spend the time and bait it. Don't make the mistake I did thinking that if I just sealed up the electronics so there was no air for a week that they would die. Nope.

MOST of the roaches we have found have been isolated to the kitchen. I want to try this, but I am concerned that using syrup in the recipe might attract ant. Though that would be MUCH better than the roaches, I'd like to avoid both. Do you know if anyone else who has tried this has had the ants coming in? I couldn't possibly read through over 600 comments to find out.

Ninzerbean (author)  Bootssie1 month ago
This will get rid of ants too. I had some coming in in my old house and just followed their line and put the bait in crevices along the line and in a few days there were no more ants.
So my apartment was sprayed last for roaches in the kitchen and washrooms....there gone from there.....but now ive seen them in my room!!!!! Gross help me!!!!! I want them gone...ive done everything possible I vaccum and clean the dog dishes about twice a week. I dont kno what to do will. Thos remedy be safe around dogs? I just want them gone :'(

Well just read the 'ible, all 8 steps, it is safe to use around pets because you won't be putting it where they can access it. The exterminators are not going to solve your problem because they would go out of business if they did. Right? This will work, just do your whole place.

Where do you think is the best place to bait the little monsters? Any good places that you would recommend?

I am SO GLAD I found your post! We have been struggling with the disgusting roach problem for a few years and we have tried everything but this. And it is pretty sad that exterminators know what gets rid of them but won't do it so they can get their monthly payments from customers. We got sucked into that as well. We will be trying this for sure today! I am so ready to be rid of these gross bugs!

Yep, when something doesn't make sense, always follow the money. And the thing is is that people would pay for a service that really worked, but it is a service that really only needs to be done every few years.

Hello, while making your recipe I added too much karo syrup and now it has a honey-like consistency. Did I dilute it too much for it to be effective anymore?

Ninzerbean (author)  JamesJ81 month ago
Just add more boric acid or flour to make it thicker. A honey like consistency is not going to be very easy to apply. It will slide off.

Last post went awray somewhere. Let s try this again. No one told me not to purchase a used refridgerator. I have never had roaches before until my fridge went up and purchasing new was'nt an option. No I have roaches .. big ones, small ones, black ones, brown ones.. needeless to say all of them.are equally disgusting. I thank you so much for helping out this single mom with 2 girls...all of which are afraid of going into the kitchen at night. Question ? I use the cordless phn base to kill one roach and about 50 more fell out after me banging it around, do I need to get rid of my apliances that are plugged in providing a warm place for them to live ? (i.e. microwave, fridge, phone charger base. Wifi box. Etc. ) Thanks in advance .. I pray this works.
Ninzerbean (author)  MsMakish1 month ago
Oh what a drag MsMakish, that is so terrible. I'm afraid you might have to either get rid of them or disassemble them to get the roaches out. Yes, they love warm and they love being inside appliances and game players.

I just recently bought a home and it is infested with roaches.... I had the Orkin man come out to spray.... a month ago and he has been back once since then and sprayed again but they are still there. By me using your mixture will it react to the chemical they have sprayed and cause it not to work? What should I do I want them gone and the orkin man told me not to Fogg the house cause it will mix the chemical and then they will not work.....

Dear Ms. Ninzerbean: Your roaches are by far the biggest I have ever seen. If your recipe killed those critters, I know it will send my puny roaches to their eternal rest. II hope your recipe will also eliminate some annoying crickets and just today - a mouse. Just one. Maybe. If your recipe rids my house of these pests, you should be given the Nobel Prize. Thanks for such a thorough, well written and illustrated Recipe to Rid Roaches.

Dear Allodynia, It won't kill mice, and your puny roaches may be the German kind so read all the comments for help with these critters. Thank you for your nomination. If I could just rid the world of roaches I would be so happy. And chiggers too, they are the worst, but at least they don't come into houses.

We had tenants in our new house for a year before we moved in. My husband 'forgot' to tell me they had roaches. I have never been so disgusted by anything in my whole life. I am afraid to go into the garage at night. So far they are oriental ones and only outside and in the garage. Thank you so much for your recipe I am going to use it ASAP. I'm embarrassed to say anything to the neighbors since we are new, but I suspect the neighborhood may have a problem also. If this doesn't work I'm getting a new house or a new husband.

Ninzerbean (author)  suzysmith1 month ago
Yup, I hear ya. But at least your husband is not afraid of them - obviously - so make him dispatch them until you get the WHOLE place baited, and have him help with that as well, it's a big job. Good luck, it will work.

Katmom1 month ago

We have such a large problem, I'm not sure where to begin. Don't know how it started...

We see them in every room, especially the kitchen. First it was just kitchen really bad. We live in a 30 year old mobile home that had been updated completely about 10 years ago except the kitchen. We thought it was the cabinets being original and they were eating the cabinets. We remodeled the kitchen this spring with all wood cabinets etc. the problem has not gone away. Since then we have redone the floor and walls of dining room and both bathrooms in that part of house. We have a 2 story addition on the house, but they had never been in that part until recently when the problem seems to have exploded. We have had an exterminator visit 1-2 times a month for over 3 years. We are clean people who keep kitchen cleaned, all food in sealed containers, trash taken out, surfaces sprayed and cleaned with disinfectant type cleaners etc.

They crawl around everywhere in broad daylight. There can be 10-20 crawling around kitchen when it is clean. They crawl over stovetop while I am cooking, I have seem them inside the microwave even after it has been running, they crawl out of the dishwasher every time I open the door(even after it has ran), anytime I open a drawer or cabinet 5-10 will come running out. We even used the Kilz paint on every surface of the gutted walls before putting in new cabinets. We got a new oven, refrigerator, dishwasher, and sink as well. If we have been gone(even in day) or walk in the room at night there are literally hundreds on every surface. We gave up trying to kill them when we see them a long time ago.

They crawl all over the living room, dining room, bedroom, and bathroom walls and ceilings. Just this summer(after finishing kitchen) we remodeled the rest of the mobile home part. (This is the living room/dining room area, master bedroom, and the only 2 bathrooms in house) Because of the remodeling this summer we have painted every ceiling and wall in the mobile home part of the house and there is nothing hanging on the walls. (Note also that mobile home part is on a foundation with a crawl space and addition is on a concrete slab). I have seen them on my bed comforter, they crawl out of the bottom of the alarm clock when I pick it up to wipe off nightstand. They fall off the ceiling onto me in bed at night. I always turn on light and check toilet seat before using it. They crawl on the shower walls.(everything in bath is new - walls, ceilings, shower, tile, sub floor, flooring, vanity, mirror, etc.) we even have new sub floor and laminate flooring and walls in living room and dining room. Kitchen has ceramic tile that was put in about 10 years ago. Sitting on couch one can crawl across you, you will not sit anywhere for 10 minutes and not see one. I am not sleeping now because they have crawled on me at night. I am afraid that I will be in public and one will crawl out from under my sleeve or something.

I don't know what kind of roaches these are. I know I need to thoroughly clean kitchen cabinets and drawers. There is the black specks, dead ones etc. all over in them. But it is impossible to keep them clean with the scope of the problem. Even within a week of getting kitchen done they were dirty. I know they are in all the appliances, toaster, Keurig, microwave, etc. I even see them crawling across the digital clock display on the oven.

I want to try your idea. (Well, I really just want to burn the house down and everything in it. Or move, but the bugs would move with us. Or tent the whole house and fumigate it) I have read every page of steps and over 400 or more of the 600+ comments, but have some questions.

1. What steps should we take before we bait the house, due the scope of this?

2. Should we fumigate/fog/bug bomb the house, clean up the dead and their droppings, and then bait?

3. What is the difference in the above mentioned fogging/fumigating methods?

4. How do I get them out of small and large appliances, clocks, DVD players, game systems, etc?

5. What about our duct work for our central heat and air systems? Should we get them professionally cleaned?

6. What, if anything, should be done in the crawl space under the mobile home side?

Thank you for reading this and I hope you can respond.

Ninzerbean (author)  Katmom1 month ago
Dear Katmon, I don't have good news for you. I think the scope of your problem is too big for anyone but a professional. Then you are going to need a commercial type of shopvac to vacuum up before and after, many times. I have had no luck myself with trying to get them out of appliances. I had to throw out an A/C after hours and hours of meticulous work. You know that expression about sometime you eat the bear and sometimes it eats you, well in the case of appliances that you can't get into every single part, you lose.
I could go into all of your questions but I think you really need to call a small (not national) extermination company that will agree to come out every time you see a bug for one price, until you see no more bugs. Then bait.
My uncle, who refuses to do anything himself had this problem, he wouldn't use my bait, the problem got so bad they were fighting each other over food left on the counter, I refused to visit, then finally he found a small company that agreed to get rid of the roaches - and they did. But because he won't bait with my stuff, they will come back.
I think because you read so many of the comments you know what you have to do, fogging the place yourself will help alot, but your cleanup has to be thorough. The ductwork questions and crawl space questions are best answered by a professional. I wish I could be of more help but you will get this under control and then bait with my stuff. It is just one of those situations where every day it will get better, it can't really get worse right?

Hi Jordan's dad,
That is pretty funny. Borax is just washing soda so you may add it to the colors too, it's just like a detergent booster.

Well who would have known, thank you for the tip. I just can't wait to see the Results of this 'Ible. The people Next door have a Really Really bad infestation, they moved and new tenants came in last week, Geez, I've never seen so many of the things. Yes I'm a Guy but they Creep me out and scare me so bad my Daughter has to deal with this. I'm signed in as her I think, She's a bit sharper in some aspects...i.e. Computers. We really do appreciate the time you have taken to acknowledge us.

Sorry not to have gotten back to you sooner - no, Borax will not work. Someone found boric acid on Amazon. Have you tried online? Call some small hardware stores where you live. The big names don't seem to carry it because I think if they did they would not need to carry about 40 different cans of sprays and stuff that kill roaches but do nothing to keep them away.

Please I need father purchased a house about 6 years ago which is where we now live...point is every now and then we saw a roach and we always got rid of them with Raid, but about 3 months ago the abandoned house next door got demolished and all the critters for some reason felt they were welcome at my house. I'm talking ants, spiders, roaches, rats ect. Despite all the pests my house got flooded with mostly rats and roaches...the rats we took care of the most reliable way we knew...we adopted cats. Although the cats succeeded in driving out the rat population there is close to nothing they can do about the roaches. Now that winter is approaching these unwelcome guests are just everywhere in my house including the bedrooms(before they limited themselves to the kitchen only!!)and last night one crawled into my ear ewww. I managed to get it out of there and now I'm just scared to go to sleep fearing this will repeat itself. People have mentioned to us over and over how they miraculously rid their homes of roaches and what they used to get the job done but unfortunately all those recipes are dangerous in a household with pets. My question is how can I apply this method in a home with cats and biggest concern is our newest cat who is still young and likes to smell and lick everything he sees. Please someone reply with some useful information on how I may rid a household with pets of roaches!!!

See step #7. I think you are not reading the whole 'ible.
I am PETRIFIED of roaches. Just thinking about them makes my skin crawl. I live in an old house built in the late 50's so we have a lot of cracks in the foundation of the house. For the past couple of days I have been seeing more of those critters then I care to see. I am going to try this and hope I have the same success as others.
Where can I found the roach prufe powder
Ninzerbean (author)  desperate housewives2 months ago
I don't know - try looking online, I have seen it as ACE hardware and it was at the small hardware store where I used to live. Maybe you can order it online...Some people have even found it at the dollar store.

Oh you know what? I meant to address the fact that you are looking for roach prufe powder and I forgot until now - anyway the point is to use Boric Acid. It just happened that the only boric acid I could find back in '09 was the 99% in Roach Prufe. But it's all about the boric acid (never to be confused with borax) and not the brand name. Hope that is more helpful than what I wrote yesterday.

I mixed the exact ingredients exactly how you made it for your own house. As I'm putting out the bait a brave little roach approaches (no pun intended) the bait & turns away from it instantly. So I dropped more in front of him, he goes up to it for just a second and then moves on again. Is this normal?
Ninzerbean (author)  Andreacatanese081 month ago

Andreacatanese08, I was out of town with no internet and some questions did not get answered, so here we go: No, of course this is not normal - BUT the point of using this bait is that you are placing it in places that roaches run around, inside your walls, under the sink, behind drawers and all the other places I detail in step 8. So maybe your little guy was on his way somewhere and was not hungry, maybe he was trying to get away from you, who knows, but putting it out in the open is not how to use it or even why to use it. First of all if you have so many that you are seeing them in the daytime you have to use some other more immediate method to knock them down, get them under some kind of control before using the bait - I say this because there must be reasons that they are out and about - such as that they can find food everywhere, or there is a colony living inside of your game player, the microwave, the dishwasher, under the stove etc. You need to vacuum vacuum vacuum, get rid of all cardboard... you know what - I have to run, just read the comments, read ALL the 8 steps of the 'ible and keep in touch with how it goes. Good luck, sorry again for my late response.

First off, thank you so much for taking the time to write this! With six young kids, I have been looking for a solution that works and from all the comments, this seems like the best option. I looked on Amazon and it states that the Roach Prufe has been discontinued by the manufacturer. The only other option is 99% boric acid and 1% lure. Do you think the "lure" will have an adverse effect? Thanks again!!
Ninzerbean (author)  maryellenlopez1 month ago
No, I think it will be fine. You are basically just adding more lure, and the other stuff makes it spreadable so it can be applied in places where kids and pets won't come across it. Keep us posted on your success

OMG thank you for this! I am going to the store right now to pick up these items. My apartments will do nothing but spray once in a while and when you keep your house pristine and they're still everywhere..I was dreaming of burning this place to the ground lol. Thank you!

Would this bait help with mice aswell since it has the buric acid? I really dont want my indoor dog around sticky traps or other stuff that he can come in contact with.
Ninzerbean (author)  Tommy7872 months ago
No,'fraid not. Mice don't wear their skeletons on the outside like roaches do. Get a cat maybe?
wenderful2 months ago
Im not sure if this question was answered, I looked through some comments and my apologies if it was already answered, but how long do I keep the paste out for?
Ninzerbean (author)  wenderful2 months ago
Start to use it as soon as you make it, it will get hard in a few hours or so depending on the temperature and how thick you made it. If you can't finish your whole house at once put it in the fridge, covered, until the next day or so. Hope that is what you were looking for.
If you meant how long do you leave it stuck to all the things you have stuck it to, that answer is forever.
JordanEaves_02 months ago

Hi Ninzerbean, I'm sorry to bother you again. I'm trying to fix this problem. I have been to 5 store none of them carry Boric Acid. Borax is also known to kill bugs, But will it work for this recipie?

Ninzerbean (author)  JordanEaves_02 months ago
No way will Borax work. It's not at all Boric Acid. You will have to order it maybe on line.
Where can I found the roach prufe powder
rduarte122 months ago
Hey ninzerbean,
I came across your post a few weeks ago and I've been going crazy with these "you know what's". I'm so glad I found this thank you for writing it. I bought my house (my first time living on my own) in 2005 we never had a problem with roaches, maybe an occasional giant spider but I have plenty of flip flops for those, about a year ago we got new neighbors. I knew the previous tenants were filthy but as long as it stayed away from my property I didn't care, but now since these neighbors moved in I've been seing more and more roaches. I've hired a pest control company (which I seen also servicing the neighbors house) and its been a year and I still have roaches. Today I went to my local home depot after going to osh and both places did not carry roach prufe, however I did find something called "hot shot roach powder" and its actually 99% boric acid, would I still be able to use your same recipe for this different brand? How often do I need to rebait? Will the roaches still be able to eat the bait once its dried?

Hello ! I live in a building that is fullllll with those devil creatures. I also have 2 month old baby. Is it save to have this around ?[he wont touch it but it wil be in the air] I am freaking out! I am able to see then during the day :( keep seeing very small ones [which i know is a bad thing] ..from the pets control came 98392 times and they have put some gel as well as some yellow pouder -no result ! long usually takes for any result ?Thank you !!I am plannig to make the mixture today [well my husband will ] and place it around ..

Ninzerbean (author)  VIvanova872 months ago
Your question makes me think that you may have opened only one page of the 'ible and not have read the whole thing. There will not be anything in the air. The bait has no fumes or odor to make you or the baby sick. It is a paste that you place in out of the way places that neither people nor pets will come into contact with. Good luck, read all the comments, it helps, every one is helping eachother with advice. Be sure to check out where your 'nest' may be - if not outside as with the larger palmetto bugs, look for cardboard, game consoles, microwaves, dishwashers, bottoms of ovens. Think water and heat.

Thank you ! If i cant find the nest and still put the paste around is it going the make a difference ?

Ninzerbean (author)  VIvanova872 months ago

I had regular palmetto bug roaches and so the colony lived outside but this will work better if you can find them inside - where they may be living just in case you have German roaches. Yes, it will still work but you must be more diligent with the German ones. Reading the comments really helps.

Mrsjo2 months ago
Ninzerbean, I have a question... My apartment complex that I've been in for 2 years now have roaches. I'm being blamed for it because the the exterminator seen my kitchen dirty one time, while I was in the middle of cleaning up. Now 1 person moved in next door to me, and before she did the person that lived there before showed me her laundry room that was flooded for weeks be cuz maintenance didn't fix it in a proper time. Someone on the other side of me moved out, doors wide open while things were being thrown out. Also there was a very bad leak in their living room for about 3 weeks. Now Ijust wanted ur opinion about where u think they more then likely came form? Oh, also they are telling me that the roaches would have been in my walls for a year and I wouldn't have known??
Mrsjo Mrsjo2 months ago
I forgot to mention, I've only seen one in my living room after they put sticky stuff in the kitchen. I've done a deep cleaning in my house and found no eggs, poo or anything! Apparently my neighbors have seen more than me in their houses, and they've been complaining for about 2 weeks.
Ninzerbean (author)  Mrsjo2 months ago

Mrsjo, I just don't know - I'm sorry you are being blamed, but from my experience here answering all sorts of questions I've come to learn that everyone everywhere wants to blame something or someone. Best thing to do is say to all that hey, we have a problem, let's take matters into our own hands and solve it rather than wait for someone who won't solve the problem because if they do they will be out of a job. Really, working together is what will solve this problem. Make friends, take charge, show them this 'ible. Be the leader!

how will this stuff affect my my pets?will my cat or dog be inclined to eat it because its sweet?we also have snakes,bearded dragons and a tarantula all of which are ,of coarse,in cages however is fumes an issue?

There are no fumes, no worries.

You are not going to be putting it in any places that your pets can access. I had the same unfounded fears because I have small always hungry wiener dogs.

allmydoggies2 months ago
Hello! I created an account just to comment. I have been looking over this and many other recipes for the last week, choosing carefully. My roommate helped me bait the house today and some of the greedy ones began eating immediately. My question is, when will I notice a difference? Obviously it won't be in a day but we've got them so bad it disgusts me. At night in the kitchen, the swarm the floor. We've had pest service before but they've come back full force. I actually think they went to all the neighbors and built an army with their bugs too. I am too afraid to walk barefoot in my own home. Also, when I removed outlet covers, the only room that showed any evidence that they were behind it was in the kitchen. Thanks for taking the time to read my reply!

hello there and have a good cockroachesless day

I'd like your opinion on something.Although you keep pointing out how important it is to put the magical staff all around your house, I'd like to put it only in a cupboard in the kitchen.

Living in a 30 square mt apartment and those last 3 years I ve been sleeping with one eye open (if sleeping any). The problem appears in summer and then dies down in autumn-winter(and god I hope it will, this time too). Thing is that after fighting it every summer, covering every crack in this hole-home (and cracks it had, my pride and joy), putting a white liquid bait all over the apartment, then adding a brown liquid bait [that made the job, obviously, a russian one] and laying boric acid this summer I had only one big dead. And then nothing. Did I say that I have German ones, oh yes, those biiiiiiiig dictators never fail bringing me nightmares.

A few days ago I saw a baby tiny winy in the kitchen.Then I checked the cupboard over the extractor (that I have sealed and never use after I realised that there must be a nest inside it). There were poo. Cockroach poo (a little difficult to be some other kind know, emphasis). I m just scared shitless to fully open this cupboard. The wood of the cupboard is not fully attached to the extractor's pipe, and this is how they travel now. I saw two other small others on the kitchen. And since I m too scared and tired to fully open it so I can put tape around it and clean it.......

Question: can I just put this magic staff only inside this area that has the problem? I ll slip it on a post-it.

obviously you don't really know since you don't have the same problem (and maybe because you're a bit more brave and you would flip this cupboard open and do your job) but an estimation will help me.

hope you'll see the message.

have a nice day

Ninzerbean (author)  ohasweethooooome2 months ago

Hi Ohasweethooooome - somehow your comment missed my inbox, I'm so sorry to not have replied sooner, usually I am within 12 hours or faster. Anyway first of all it's been 20 something days - how are you doing? I would have told you right away not to only bait where you see them, bait the whole entire house, it's vital. And you just have to be brave, think of people with REAL problems in Bosnia or somewhere who would trade your fear of opening the cupboard door with about a hundred other things. Or snag some person you meet to help you. Let me know how you are getting on, and I really apologize for missing your question.

Ldivasmom2 months ago
Hi I am wondering your thoughts I this working for me. I live in a row home and my neighbors are very nasty. Our problem started last year and we hired a professional extermination company and they come monthly. After a few months we saw improvement to not seeing any at all. Now the roaches are back full force like we don't have an exterminator come regularly. How could this happen if we have constantly been using them? Do you think this paste will work even though my neighbors is the problem? How much of this do you place out and where specifically? How soon to see results? Please help
Ninzerbean (author)  Ldivasmom2 months ago

For the last few weeks I am getting questions like yours that are answered in the 'ible's steps, yet I think people such as yourself are not reading the whole 'ible. Please read the whole thing, everything is very clear about where to bait, how much to use, why it works, etc. Exterminators do not, I repeat - DO NOT stay in business if they are successful, understand that and you will understand lots more in life in general. If you just want to do good in the world have a quality product, if you just want to make money have a crap product that works to solve the symptom and not the problem, and hope you don't believe in Karma.

Just follow the steps, you will soon be fine.


I believe that roaches are in the ceiling above my kitchen (the house has 2 stories). On several occasions I have seen them on the ceiling, and it's always by the recessed lights. What can I do about this? In addition, I have seen very tiny black roaches come out of the drain in the bathroom a few times.I am on a crawl space if that makes a difference. I did have an exterminator come by and spray and informed him about my concerns about the roaches coming from the recessed lights, but he blew it off as that's being impossible. Sometimes, I'd find dead roaches around the house, I just don't know what else to do. I know what I see. I do live in a wooded area if that helps, and it's not the type of roaches that people find on their kitchen counter, but a roach is a roach to me. Before we have guest over, we always check to see if a dead roach is around, plus I was SUPER embarrassed when on two occasions while in the kitchen one was pointed out to me on the ceiling...good grief. I have several questions;

Is it safe for me to take down the recessed lights and put the paste in?

How can one treat for possible roaches in the ceiling/walls?

What can I do about the tiny black roaches that I have seen coming from the drain in the bathroom sink?

Would you suggest I go under the crawl space and put the paste near the vents leading into the house?

It is possible that roaches are in the walls, what are my options?

I do have an attic, but I'm afraid that if I go up there I may misstep and fall though as it's filled with insulation and therefore I am unable to see the beams. Do I have to put the paste in the attic. or putting on the exterior of the house somehow?

Any help will be appreciated. Thanks.

Ninzerbean (author)  AlwaysGrateful2 months ago
You will be in for a large amount of money if you mis-step in your attic and come through the ceiling. Most of your questions are answered in the 'ible, make sure you are clicking to view all steps. The guy who blew you off is what is typical, and he knows NOTHING about where roaches live and hang out. Simply put, just following ALL of the steps in the 'ible and you will soon be fine. Little dabs anywhere you can get to inside your walls and ceiling will be fine, most of the time it is very difficult to remove ceiling light and get inside the ceiling, do your best, but if it is really hard just forget it, you don't need the added expense of an electrician. Once you bait and bait REALLY properly you won't have anymore embarrassments on the kitchen or guestrooms. Remember the expandable foam - use it in the appropriate places. Stay in touch.

I have had a problem with roaches for awhile. I have been using a spray, but there too fast. There infesting my kitchen and bathroom! Its gross. I Found the product Boric Acid Roach Killer at Walmart. It has lure in it. Will that affect this recipe? Also, Can I put this in different bowls throughout my house? Thank you.

Ninzerbean (author)  JordanEaves_02 months ago
Bowls? No. You need to read the whole 'ible. Hit the button to view all the steps, obviously you are only seeing a bit of it. And no, that product will not be the same, I would not use it, the purpose of the 'ible is to get the roaches to bring the bait back to where they live so they can tell...oh nevermind, I am tired. Just read the whole 'ible. The comment section will help as well. Good luck.

Hello :D. I've heard about recepies like this with boric acid all over the web! The first time I started noticing roaches in/around my home, was when I found some dead ones a few years ago in the garage. I didn't think much of it and moved on. That was also the year the pest man stopped spraying around the house. Well 3 years after that, I saw a small, light brown one in the hallway, two light brown ones in the kitchen and one dark one, another large one in the bathroom (E_E), and countless in the garage. All of these were at night. I have an extreme fear of them, and seeing alot of them just made it worse. The pest control man sprayed, which kept them at bay for a week at the most. Towards the Fall/Winter months, I started seeing fewer and fewer of them (Except for halloween, when the Jack-O-Lantern was on the ground outside and there were a few small ones in there). The year was tapering down, and we weren't seeing any more until May of that next year, when there was one in the hallway on the other side of the house, (a place i've never seen them). It was a medium brown one, which we killed promptly. We called pest control again (this time a different, smaller company that was rated highly). They put out a cream that looked like butterscotch, and by the next week we saw 2 crawling around outside dying, and found 3 dead ones out there. I only saw one in the garage that year, which made for a relaxing Summer. Fast forward to this year, the Summer was awesome, but I saw 2 roaches outside. One was when I moved a pot (where it was damp and dark before). The other one was at night, when I went outside to get something. A big one crawled from the bench to the grass. Since they were outside, I thought: A. They might be Palmetto bugs/Water bugs, or B. That's their natural habitat. I went all Summer without seeing one inside until yesterday, when there was a small, light brown one in the bathroom. Do you think this bait will work for me? Thank you!

Ninzerbean (author)  KawaiiSugoiChanel2 months ago
I think that the butterscotch bait was probably the same thing. The person probably just did not use enough of it - well I mean he or she probably did not thoroughly bait your house. It takes hours. I think it is against most codes to put the bait inside the outlet covers the way it was done for me when I lived in the first house in my story. I don't think though that you can expect not to see them outside.

So do you have a lot of cardboard in your garage? Anything that roaches like to eat? Well get rid of it.

And, yes, I think that this will work for you. Next time you can leave out all the details of color etc. - remember I am very afraid of them as well.

Sorry :P I thought the color of them mattered, because there are different types :\

Ninzerbean (author)  KawaiiSugoiChanel2 months ago

Yes, I was sort of kidding, sort of serious, it's just TMI for me personally.

JessicaM62 months ago

I KNOW THIS IS LONG BUT IT WILL HELP....I Am still in the process but this is my pIan. I wanted to comment on this as I am currently dealing with a German roach infestation thanks to my lovely mother and father in law. ( I am hoping after I rid myself of the problem I can help them as well ). I have spent more time in the last week researching German roaches than on anything else in my entire life. I have a 3 year old and 5 month old and cannot believe i have to deal with this. First of all I did use this recipe and it works great especially because you can use it in outlet covers, which is the German cockroach highway, it is how they travel. But I also used a mix of other things. I first started by getting rid of my toaster and microwave I saw babies climbing out of the vents on the side. I invested in a ton of 1 gallon ziploc bags ( the ones with the zippers) And big plastic crates. All of my cubbard food is in ziplock bags and all inside of a plastic crates with a lid, in all of my drawers everything is washed, dried and in plastic bags, I made my kitchen almost like nobody even lives there. I have completely quit using the dishwasher for now and have a strainer I wash and dry ( Drying is especially important as they love water) all dishes right away and put them in a big plastic crate, I have even been using paper plates because i have 2 kids and hate washing dishes but I take them out to the burn barrel right away and burn them, Germans love cardboard. Soooo after all that I not only used this recipe ( Which is great ) But I also bought Gentrol Point Source IGR, which is an insect growth regulator, It actually stops the babies from reaching sexual maturity therefore....NO more eggs. This is key!!! On top of baiting this is a must for Germans!!! Ok so as well as using this recipe and the IGR, I am going to put any extra clothes, books, blankets In Ziploc space saver bags. I put this bait everywhere, as well as chopped up banana on plates with boric acid sprinkled on top, from what I have read they love banana. When I tried just this recipe ( Which wasn't intended for german roaches) It helped a little but they breed so fast, So the IGR really is what is needed on top of thorough baiting.Also DO NOT ever spray them, all it will do is move them to other places in your home. I really hope this helps somebody because when i realized I had this problem on top of having a 3 year old and a 5 month old I sat down and cried, I felt so overwhelmed. I have just started this process but like i said i have researched this more than anything else in my life, and I really feel this is how it has to work.

Ninzerbean (author)  JessicaM62 months ago
Jessica - I really feel for you, this is a terrible situation but you really have a handle on it and I promise you that this will be a distant memory by the time your 5 month old is a six month old. Everything is better the next day, everything seems less horrible. You have learned so much and you are so generous to pass it on to all of us - so a big thank you!

I tell everyone with Germans to get rid of all the cardboard in the house, even pasta boxes, store it all in ziplocks.

I don't have a microwave any longer either, but not for the same reasons as yours but I don't miss it a bit. Soup tastes better heated on the stove and when I put things into the oven to heat up I am so busy doing other things that the time just flies and the crispy parts are so tasty.

Anyway please keep in touch, yours is the best info to date on the Germans.

I just moved into my new house a month ago. I over cleaned everything pulled out stove, washer, dryer, and dish washer and cleaned behind around and in. I seen the Terminix truck at the house next door about 3 weeks ago.. I knew it was trouble. Now I am seeing roaches, ewww.. I am totally disgusted and freaking out over cleaning everything and I have three kids and totally freaking out about this new found problem. I cannot wait to try this recipe and get to work at ridding them from my house. But also totally freaked out about even opening the attic crawl space.

I wondered, would you place this paste outside of the home in the cracks?

Or would that just invite more unwanted bugs?

Since i am renting I am still going to have the landlord at his expense spray the house while I will bait everywhere.

Ninzerbean (author)  Branderdini2 months ago
I always used any left-over bait outside but really it is quite difficult to find places to actually put it where it won't wash away. I think you are doing the right thing. A good knock down doesn't hurt, just don't sign up for any monthly thing or you will be sure to have roaches every month.

I really know about the freaking out part, my heart goes out to you, been there. Sometimes it helps to play a game in your head and think how scared they are of you and how you are saving your children etc. I don't have anyone to help me so the occasional one I see I am on my own to dispatch it, my wiener dogs go nuts so I go nuts and I get out the central vac and make sure to hunt the lone sucker down. I pay people who come over for other things like the A/C or whatever to empty the canister. See what a wimp I am?

UGH Thanks to my neighbors I have a huge infestation of Roaches, that I see during the day......And after I stop dancing around and dry heaving, I am going to try to calm down. I live in an apartment building, and odly enough the roaches I have live in my dishes. I have not found them in my food cupboard but that doesn't mean they havent been there. My landlord is coming to spray tomorrow but if that doesn't work I am going to try your paste, although do you think it will work if the rest of the apartment building is infested too? I have only seen them in my kitchen does that mean that the rest of my apartment doesn't have any or do they just have free reign of the place? Ugh I hate hate hate cockroaches!!!!!! In the meantime I am throwing away all my food that isn't in a sealed container. :(

Ninzerbean (author)  denise.reddekopp2 months ago
Well spraying will kill the ones that are there but it does nothing to stop them from returning, it's how the pest control companies stay in business. Who else would we pay money to every month to do the same thing that does not work for longer than a month. Is your landlord licenced to be a pest control person? I would never let an unlicensed person use poison around my living area. Don't be crazy. No one but your mom has your best interests at heart.

Slow down, think about this, read the whole 'ible, read all the comments. Think before you let the landlord spray your place - if he is not licensed to do so. Hire a professional to knock down the infestation if it's really bad and then use my baiting system.

Have a meeting with the other people in the building to discuss this problem, show them the 'ible, maybe you can all work together at the same time so that all of your can be free of roaches.
Sorry I meant that the landlord hired an exterminator company to come in. So I would have to assume they are a professional company.
I am still going to use your system though. It sounds like the only permanent solution to the problem. :)

Thanks for your reply

can I use this in apartment in the presence of a crawling baby?

Ninzerbean (author)  asma.rizvi.7982 months ago
Does your crawling baby crawl inside of switch plate covers and behind toilets and inside of cupboard behind the drawers, on top of pocket doors, behind picture frames, under sinks and inside of crawl spaces? If not then it will be fine ; )

We recently moved from our old home in which we lived for 6 years without as much as one roach. now here a week and we have found 6 baby roaches (mostly at night) in the kitchen and half bath area. Went out to Menards and got the boric acid. Only type in this town is only 64% boric acid. Hope this works

Ninzerbean (author)  james.wiggin.122 months ago
I don't think that will do the trick. Perhaps you could order some online?

its me again. So far, cockroaches number already decreases so much. I see them less now and hard to find. Also, the hoi hoi traps that i used there are only few cockroaches there now and most of them are babies. I wish to eradicate the, completely very very soon. Hmmm... Its hard to get rid of them, it requires many patience specially when cleaning all the poop they had. Im glad numbers decrease great. Thank you so much for this.

Thank you for staying in touch, yes it is difficult because they live in so many places you would never think to look - like electronics! PS3 players, X-boxes, air conditioning units. Keep fighting. At least you are winning!

My husband and I moved into an area of the city that was a little impoverished and is being revitalized. I have never had roaches before and as soon as we moved in they came out. I have tried bait traps, a few home remedies, raid, and other bug sprays. no amount of cleaning or spraying these disgusting evil little things has gotten rid of them. Unfortunately I have seen them go into electric sockets in our home and I can't exactly seal them. I am going out today to get the Borax I have all the other items, I sure hope this works otherwise I told my husband we are moving into a hotel for a week and bug bombing the house! Oh also I hate to say this but I also just read don't smash them the other ones will eat the remains...great.

Ninzerbean (author)  Amandalynlewis21792 months ago
HI there,
I feel what you are going through, I hope that your writing Borax what a typo. I really hope that you really went out and bought boric acid. Borax won't do any good for roaches. Be sure to read the whole 'ible, especially about putting the bait inside your walls. It's going to be a battle. Good luck, keep me posted.

I have a German roach problem in Florida in the swamp. It's literally the perfect storm of pests. I'll definitely try this recipe. Keeping my fingers crossed that it works.

Ninzerbean (author)  tricia.yeager3 months ago
The Germans are very hard to get rid of, read the comments as you are waiting for them to die, you will learn a lot. Be tenacious. Some people have had good success and other's not so good, but I wrote this for the giant ones... It was a long time ago and I didn't know the habits of the Germans back then. It will work, but you just may have to add other things to the arsenal of weapons, depending on your situation. Keep me posted though.

I made your recipe and it seems to be working better than store bought baits! Its really easy to make and I'm using it as a stand alone in one room and with regular raid in another to directly compare it. My problem is far from over but I'm very happy with this malleable and useful idea!

Thank you Gina! I don't think that that termite recipe is correct. It makes no sense, cat food is not what termites eat. I know that termite treated wood is treated with boric acid, but surely not with cat food. Not to mention jelly. Please look more, this can't be right. If you get rid of the pinebark mulch I think you can be sure the termites will leave as well. Why are you not using cypress mulch?
Thanks for getting back! I made the roach-be-gone goo and placed it all over the house and garage as you've directed. Florida has certain seasons when the bugs are worse. As the dry winter months near, I now feel prepared for them as they are attracted to moisture; pipes etc...
As to the other recipe, I thought it a little odd also and while I bought the ingredients, I didn't make any yet as I have 2 cats and an aging Golden. I am still designing an inaccessible way to bait. Here is the site I found it on. Any input would be great. As to the pine bark, it doesn't seem to matter, I used cypress in my side beds and they ate that too. Also found them in my garden where I mixed in some peat. They ate my pressure treated deck in 4 years. We don't call our place Junglehouse for nothin! lol
I loathe to use poison. Any idea before I have an army of raccoon and panthers after the cat-food bait??? Sincerely, gina

Hello! I am about to try this out. We bought our house a little over a year ago and recently, some disgusting neighbors moved and well.. all their bugs came to our house! :( My question is, I have boric acid but its not blue.. its called "boric acid III." I don't know if that'll make a difference or not. I didn't see anybody post anything about this in the comments section, any idea?

Ninzerbean (author)  WelcomeToGlitterville2 months ago
As long as it is boric acid (please, not boric soda) you will be fine. Sorry about your neighbors... but maybe that is why they moved.

ugh, sorry it posted through my business page.

Hello everyone, I live in FLA and never had a problem with roaches thanks to do your own pest control shops and websites. Here in NC it is aweful. I have the exact same problem as ohasweethooooome.

They only are here from June to October. Then finito. Even in the summer, however I never see roaches in my kitchen at night. I can open the light in the bathroom or kitchen late at night and NO roaches. Once in awhile, during the above mentioned time period, I see a live on or a baby one. Maybe once a week and that is during the day. I have made your mixture and put it outside. I have also taken large pieces of duct tape and put a dab in the middle. I do this outside because I tried inside and caught nothing. Buy the real duct tape and this works wonders. My mix is not blue because the boric acid I use is white. I still am afraid to leave my home for a vacation because I wonder what I will come back to!

So did you just leave the bowl out or did you actually put it on things (like roach bait?)

Ninzerbean (author)  katreceswenson3 months ago

I don't understand your question, sorry.

dcarma Ninzerbean3 months ago

I had the same question... once you've made the mixture what do you do with it? Roll it into balls and place on work surfaces? How far apart?

Ninzerbean (author)  dcarma3 months ago

Sorry for the confusion, I think a few people may be new to the site and are not clicking the button to see all the steps on one page, step #7 explains how to use the bait, but really, you should read the whole thing. Not just #7.

she means do you just leave it in the bowl or do you scoop it out an put it in certain places? I was wondering the same thing, do you just spread little bits of it in random place throughout your house? Just kinda curious as to what you do with the mixture

Ninzerbean (author)  crystal.m.davis.183 months ago

See step 7. Maybe you are not looking at all the steps? If you are not a pro-member I think you have to click a button to view all the steps on one page, I guess that that would make the 'ible a bit vague if you were only see the first step. Thank you for explaining what Katreceswenson was asking, really I had no idea.

we have a bad problem in our kitchen in our apt and nothing we have done has helped people have come in and sprayed and even bombed i cleaned everything out and still nothing I am going to try this and I hope it works

I just put down my first ultra cheap mini batch. It seems each time the apartment exterminator visits (monthly) the little critters get flushed our way. I noticed the only difference from what I prepared and what the dude used is the color. I prefer the DIY approach. Thanks in advance for your generous and helpful advice in the road toward a solution to a common problem.

wpickering23 months ago

How about adding a scoop of Cypermethrin to the mix? With the sugar content of the syrup, would the repelling feature of the chemical be mooted, or would it counteract the entire process?

Ninzerbean (author)  wpickering23 months ago
If it ain't broke, don't fix it. This works, there is just no reason to add Cypermethrin.
gina.camarata3 months ago

Thanks for your courageous effort! I made a boric acid paste once to kill ghost ants and it worked great, but I only made a teaspoon to use near a water source they were invading.(the spray nozzle on my sink) Now I have high hopes for your blue goo roach killer! Florida living is a bug trial at best. There are zillions of creepy crawlies everywhere. The stuff is on my list and I am going to the store right now. I will keep you posted. PS: I found your site while searching for a termite killer recipe. Every garden bed I have is infested with them under the pine bark mulch. The recipe for that is Boric acid, grape jelly and cat food, but it needs to be inaccessible to pets and wildlife. I will keep you posted and pass on your wonderful site info. krzycat55

OMG! Thank you so much. I was mortified when I discovered what this bug was and in my kitchen! It seems I have the german type, but this site is the best I have found on advice. I will update everyone soon as to how this goes.

its been a week since i put a homemade bait and this hoi hoi traps everywhere. But im frustrated coz it looks like they are still many of them. I discover their nest at the back of out refrigerator and we clean it and put q bait. Now i made another bait again using peanut butter. How long does it take to kill them all?

Ninzerbean (author)  Jonettemardavid3 months ago
I could answer you but I really can't stand looking at that photo. All the answers though are in the 'ible, and in the comment section. It's quite a lot if reading but anything I wrote here would just be repeating.

I have had a serious German cockroach infestation for nearly 2 years. I just spent 2 weeks emptying my kitchen cabinets and moving all the appliances so I could dust boric acid and diatomaceous earth everywhere - everything is back in place and NOW I find your instructions! As soon as I catch my breath I'm going to whip up your formula and start all over. I can't believe I have to take all the switch plates off yet again. My roaches reside mainly in the kitchen. When I make a sandwich I have to be fast. If I have to go back to the fridge for a tomato or mustard there will be at least two roaches running at break-neck sped toward the sandwich! "Shy" is just not a word that applies to roaches. I am slowly making my way through the comment section here and I am amazed at the people who use wicker. German roaches love anything made of straw or wicker. I have had to discard everything made of straw and wicker because those materials provided so many hiding places that they were just teeming with Germans of all sizes - particularly babies and small nymphs. I will let you know how it goes. You have a very pretty kitchen - you must be a serious chef.

I don't know what the Germans use to kill "German" cockroaches but I do know that they call them "Russian" cockroaches!

Ninzerbean (author)  LindaF13 months ago
For a problem as bad as yours I would also suggest that you get rid of any cardboard containers such as cereal boxes, pasta boxes etc., maybe even put evertything with a label into some giant zip lock bags. Also check your dishwasher if you have one. Or any appliances. I think you need to fog the kitchen. Let me know how it goes.

Thanks for your prompt reply! I have already put everything that was in a cardboard box in zip lock bags. From what I have read on other sites, fogging does not work well for Germans because they can hold their breath for 40 min. Is fumigating and fogging the same thing? I have two questions:

(1) How long does this formula stay spreadable? I am a slow worker.

(2) Does this formula definitely work for German roaches? I have now read all the comments and sometimes it is hard to tell if people are discussing palmetto bugs or German roaches. It appears that some people use this formula successfully with German roaches - but, then, there are a few who apparently are not successful even though they affirm that they are following your instructions to the letter. I have a few Palmetto bugs, too. So I am still going to do your formula. It is hard to live in SC and not have Palmettos.

Even though I have read that the only reason you see Germans during the day is because they are experiencing crowding - I don't know that I believe it. I have destroyed four nesting areas in my kitchen during the last month but the number of roaches I see during the day has not lessened. I think the reason I see them during the day is because they are hungry. Since I have been discarding food scraps left on dishes immediately and taking the garbage out every night before bed, daytime roach activity has definitely increased. My German roaches are very aggressive. When I cook, either day or night - as soon as they smell the food, here they come. They crawl right on the stove among the cooking pots. If I'm slicing and dicing, they come right up to the food prep area. They act as though it is their kitchen and I'm just the "worker bee!"

Ninzerbean (author)  LindaF13 months ago

Dear LindaF1,

The bait will stay spreadable for at least 4 or 5 hours. But you can put it in the fridge and that will give you some more time. I now live in SC too. In the woods even. I still don't have roaches, except a dead one every few weeks, since I baited this house when I moved in 2.5 years ago. Fumigating and fogging are different. I really wanted to say bomb but am afraid Robot will hold up my reply to you. So anyway, I too of course have read all the comments and seen that some folks have had varying luck with the Germans, and I have learned a lot. This works like a charm with the palmetto bugs which was what I was dealing with in Ft Lauderdale. But in SC I have seen both and the Germans are the dead ones I find. No palmettos.

I recently talked to a restaurant owner about this solution and he was going to try mixing up a slurry of the bait and put it into standing water. This is fine for a restaurant but not something you want to do in your home - but in your case I think you might want to try something along these lines because unless you are pulling my leg you have a severe problem. Like your health is at risk from the bacteria and stuff these guys carry. You need to take really drastic measures.

Finding the infestations is fantastic, if not really gross, but I think you may need a severe knock down that only an exterminator can do, not a regular service call but something special. I would call a non- national company to find someone that can work with you and your situation until it is under control and then use my bait to keep it under control. In my situation there had only been infestation inside and it was in the bottom drawer of the oven in the house we had rented. But I'm worried that your problem is even bigger than " the worst infestation he had ever seen" as I wrote about in the beginning of my story in the 'ible.

I'm on vacation and using an ipad instead of my computer so there are sure to be tons of typos here. I hope you can work through them. Pls stay in touch.

therese87 aaryak6 months ago

I read that if you do this you need to be careful not to leave any trace of the roach guts because that will attract more roaches as they enjoy feeding on the remains of their dead buddies :(

i will try this, but its hard to find the boric acid powder in japan, so i just bought the market ready roaches bait with boric acid. I bought something like rice cake flavor. I hope this will work. I upload an image of what i bought. The box has 16 pieces so i put it on every place that roaches may live. This post help me about boric acid

Ninzerbean (author)  Jonettemardavid4 months ago
I don't know, I sort of don't think this is going to be the same thing as my 'ible. I mean it does not seem to be any different than using the store bought stuff because it is just that. My baiting system is all about putting it (because it is sticky) on the backs of drawers, water pipes, behind toilets, up high, inside walls. I am sorry that you cannot find boric acid powder in Japan. Can you maybe try harder? A chemist shop maybe?
Companies do not want their roach bait to be effective in being brought back to the colony, they want you to see dead roaches laying around so you will think it is working, but that will not get rid of the problem. It will just make you buy more of it. If you use my system the roaches are gone for years and years, you only have to do it right the first time. It takes hours but it is worth it not to have to do it again for years.
I was out of my house for 2.5 months and got home last night and no roaches anywhere - dead or alive.

ok i already able to get the boric acid online and follow this step. i use mapple syrup. i hope they die very very soon. i have seen many of them at the back of the refrigerator, i have clean it and put some of this. ive been using a hoy hoy traps too.

wireman3323 months ago

I first wanted to say thank you for sharing this information. My mother has started having a problem with roaches showing up, and its really started to get to her. She cant stand the thought of it. Im going to make your mixture and spread it where you have shown.

Secondly i want to comment on the social argument going on in the forum. And i'll have to agree with the NOT social side. The definition of a social insect is "any of numerous species of insects that live in colonies and manifest three characteristics : group integration, division of labor, and overlap of generations." Roaches do have two of the three, but miss out on the division of labor. There are no "queen, warrior, or working" roaches.

But yet they do form colonies, and interact as Nizerbean has stated. I read of one study where the group made a cockroach robot that had characteristics so close to the living creatures that it was able to get the whole colony to follow it to anouther living erea. I looked for the webpage that was on before commenting here. While i was unable to find that particular page, it looke like they might be marketing the creation already. But why go through all that when such a simple solution as this is available.

Thank you again Ninzerbean, best wishes.

Ninzerbean (author)  wireman3323 months ago

Thank you wireman, very interesting - thank you for taking the time to write. I think that the comments to 'ibles are as valuable or more so, than the original 'ible.


If you follow the directions on where to put it your animals should not be able to get to it. I know that I would not my animals to eat it but on the other hand it should only hurt things that wear their skeletons on the outside. You should do the research you need to know. Don't just take my word for it.
boni143 months ago

Is it still effective after it get dry and hard?

Do you have to retreat. What about Apt. living? Thanks for info.

Ninzerbean (author)  boni143 months ago
Of course, depending on where you live and how humid and hot it is it will get hard or harder, but you want it to, you don't want it sliding off of all the stuff you have put it on the back of or on top of. If you don't use it all in one day it will be unusable to apply. I would only think you would need to re-treat every few years. I don't have first hand experience with apartments but from what I have learned on here in 6 years I think I would try very hard to get the other tenants on board.
shyatt28 months ago

I made this, after scouring the interwebs for different recipes what i have found is the same. It doesn't warn the roaches not to come back. The point is they eat it and they dry up and die. The roaches in the nests eat those roaches and die also. The syrup and flour/rice powder is the attractant. This is the same technique used in the little pods. Just much cheaper to make a large amount. Depending on your infestation it can take weeks to see results. This is why bombing/spraying to kill visible ones is important. Roaches come in waves as eggs hatch, so you will see them in crease in numbers before they dissipate. This bait will generally outlast the waves of roaches which is why it is much better than the pods. Once you properly bait your house with this stuff and they start dying off your house will be protected as long as it remains appealing to new roaches that come in from outside. Using an oil agent to keep it from getting rock hard can make it last longer. Source: I have successfully destroyed a german roach infestation with this recipe.

boni14 shyatt23 months ago

Thanks for suggesting the oil to prevent drying out and make it last longer.

Ninzerbean (author)  shyatt28 months ago
No, the bait doesn't warn the roaches not to go to your house. Roaches live in a colony like bees, they communicated to each other about where to go get the best food. The German ones live inside, I wrote this 'ible for the regular ones I had to deal with in Florida. When I wrote this back in '08 I think it was, there was no information online about baits, just digging and digging led to me discover that the pest control companies were stopping the use of this type of bait because people were canceling their contracts. Your information is very helpful, thank you for sharing.

best bait I 've heard of.. what also works is, if you see them in a path or a route, sprinkle baby powder down. when they walk through the powder they will suffacate because they breath through the underside. LOVE the borax recipe for places you can t sprinkle powder or for the buggers you don t see. I have wood roaches, because I live in an old house in the woods, and it works on them too! I have seen Florida roaches and they are really, really big and scarey so if it takes care of them, it will take care of every day roaches. thanx for the recipe.

Ninzerbean (author)  reikimaster55557 months ago

Thank you! And thank you for your tip about the baby powder.

shyatt2 shyatt28 months ago

Protip, german roaches use your electrical lines to get around the house. Make sure to bait inside your outlets, take off the coverings and bait inside.

Ivriniel5 years ago
Um, roaches aren't social insects so they don't form colonies.
boni14 Ivriniel3 months ago

Yes, they are very sociable.

Ninzerbean (author)  Ivriniel5 years ago
Yeah they are and yeah they do. Being that I saw a colony move one night I know this is true - a river of roaches - millions? Who knows. But check out LittleWolf's comments and some others, they attest to the social and colony stuff.


Although it is clear they live in groups and have some means of communicating, still,I wasn't so sure about a "colony", so I did my own Googling and one thing I found, and thought you might find as entertaining is according to this list: (scroll down to "Invertebrates") where you will find that while "ants" live in a colony, a group of cockroaches is actually called "an intrusion"... This would imply that no matter where they might be, they are not welcome there!

At any rate, I thank you for your contribution, and for your continued support of this ible you were so kind to share. My story start with me moving in here almost 12 years ago... I happened to see 2 dead roaches the first day I got the keys, so I put off moving for a day and used several foggers to try and get rid of any infestation. I don't know if that helped any but I have had many small harmless spiders, I never had a single cockroach, not dead and not alive. NONE.

Well, until this last new neighbor moved in a few months ago. As soon as he did move in, I noticed a big jug of name brand bug spray sitting on his patio. That's a big clue, as far as I am concerned as to what was to come. Sure enough and it was a few weeks after he appeared on the scene that I saw the first cockroach... And downhill it went.

I must say I started with the easiest of ibles I found on here, the "salt" method... And aside from (presumably) salty feet it did nothing else. Then I went on to the sugar and baking soda... Or was it flour and baking soda? I think I did both. And while I have used Boric Acid (in a mix with sugar and water) to get rid of ants in my garage -And I must say it worked like a charm- I have never used it for cockroaches but am now down to your recipe...

While I cannot doubt how effective it is, theoretically, I don't think it will permanently get rid of the problem because while it might eradicate those that cross the border into my unit, they may continue to thrive where he is at. In all fairness, I should mention that while I do not buy or read the local newspaper in my town, it was shortly after I had spotted the first few roaches in my kitchen that I came across a news stand that showed the front page of the local paper with a huge headline that said "ROACH INFESTATION" discussing how this summer might present a huge challenge with the little critters. So while I maybe attributing the problem to my neighbor by way of the jug of pesticide he has, it might be this whole town that needs to be treated, better yet, eradicated.

And so I think I might be simply delaying the inevitable, that being moving out and letting them have the whole place. And if an when I do move, I will only be taking the bare minimum... No cardboard boxes, no "I'll save this that or the other in case I need it later".

Thanks again for your contribution and I will update you with my success (I hope) or lack thereof!

Ninzerbean (author)  Omarsibles4 months ago

Dear Omarsibles,

If you would be as good a neighbor as you are a writer then I am sure you could approach your neighbor, without blame of course (because it is possible he ended up with a used infested ps3 player as so many others have) and say hey we both MAY have a problem, let's see if we can fix it together. Or how about going to the person who wrote the article in the paper? I am not trying to make money or fame, I have no vested interest in boric acid or any other M.O. other than to rid the homes of the world of roaches.

But you are really a great writer, do you write professionally? Where will you move to? Do you really want to move? Don't let the bugs win! I just visited the greatest town on my way home from months of travel - Fredericksburg, VA. I think I am going to go back with my cape on and rid that town of roaches, and having too many letters in its name. Actually I have no idea if they have a roach problem there or not.

Keep in touch.

Ninzerbean (author)  Ivriniel5 years ago
I just did a Google search on roaches being social and there were many hits - too many to just list one, but really you can look there if you want proof. I put as the headline "roaches are social?" I hope this will convince you. It's one of the reasons they are easy to kill. If you had to kill one at time without their help in bringing poison back to the colony you would never make a dent.

therese876 months ago

Hello, I have a cocroach problem and every once in a while see one in broad daylight (maybe once every week) and at night when I get home and turn the lights on there are at least 2 or 3 of em in plain sight. I tried a mixture of borax and sugar (2 parts borax to 1 part sugar) which I placed in 5 different likely places around my house, but I'm not sure if it did anything. It has been about a week and I have found a few dead wasps and large dead ants, as well as a brand new trail of tiny live ants, but no dead roaches. I saw no roaches at all for a few days, and signs of trails in the powder I had laid out, but no dead ones around. Then I saw about 3 or 4 all in one room, and now, a few days later as I got outta bed to use the restroom I saw ::gag:: 3 huge ones. They did not look at all like they were suffering the ill effects of borax. They looked very healthy and happy. I am so squeamish I can't squish them, so I desperately used up a whole bottle of hand soap trying to pour it on them, but two got away, and I only was able to suffocate one of them. I think I need to try this recipe, but I have a few questions:

1. Can I use borax instead of boric acid?

2. Does this recipe work on the giant ones I have here in Louisiana?

2. Will I see dead roaches around if it is working properly?

3. Will this recipe continue attracting ants into my house?

Help! Thanks in advance!

Ninzerbean (author)  therese875 months ago

Hey therese87, I'm back, how are you doing with the roaches? Did you find some Boric acid?

I did find some Boric acid. I have not had the chance to make the mixture yet, but I am still seeing signs of having an infestation. My house has some pretty old electric wiring, and all the electric outlets are in the floor. Any idea how I would attach paste underneath them to where it won't just drop to the ground? Thank you! Actually, I have been finding a lot of dead spiders near to the borax mixtures I left dead roaches though.

Ninzerbean (author)  therese875 months ago

Dear therese87,

I know I am going to sound like a grouch but again your questions only would be asked if you have not read the 'bile. Are you sure you are hitting the button that says "view all steps on one page"? You would NOT want to see dead roaches after using this bait. The whole point of it is for them to take it back to where they live so they can spread the news that your place is not a place to go to. They are like bees in how they communicate to each other.

Secondly it should not matter where your outlets are located for you to be able to take the covers off and (against all codes) put the bait inside the receptical.

Again, Borax is not, nor does it even contain, boric acid. If you have roaches and you have not used this mixture that I detail in this 'bile I am unsure of why you are writing about it not working. I am sorry if I seem at all negative, and believe me I have total sympathy with your problem, but the question about the location of your electrical outlets just makes me wonder what you are reading and what you are not reading. Can't u see from the photos that the whole reason for the paste is to be able to put it on vertical surfaces? Behind drawers, behind picture frames, on pipes, inside electrical boxes (again, against code) are not even vertical no matter where they are placed on your walls.

Ninzerbean (author)  therese876 months ago
I'm out of town and it's hard to try and answer from my phone but most of your questions are addressed in the 'ible and the comments. Borax will not work. I'll write more when I return.
FancyCheese5 months ago

I have a problem with large roaches coming into my home. They're not palmettos but the North American variety. I read that they don't live indoors but outside but an exterminator told me that they will sometimes live inside the walls. I don't even know where I'm going with this but I'm writing this in hopes that someone can give me some insight as to how to get rid of them once and for all. It's really taxing on me emotionally because I hate roaches (deathly afraid) and now.. whenever I think I see anything move from the corner of my eye I freak out. The main thing I'm afraid about is that if I do try this method out...could it possibly attract more roaches to find their way into my house?

I really understand how freaked out you are. But this method is not going to attract more roaches to your house. Really. Trust me. I swear. Just read the whole thing through, read the comments, take you time baiting your home completely.

By North American variety I think you mean the big ones - those are indeed called palmetto bugs. The German ones are smaller and they do live inside of homes. They are harder to get rid of.

I'm applying it right now! I really hope this works! It's only the bathroom and my room that they've been getting you think I should still apply it everywhere? Thank you !!

Dear FC, if you are asking that question you have not read the whole 'ible. Please go back and read the whole thing. You have to do it right for it to work, like most things actually.

Question, I irrigatem if I were to put this outside, or say in a sink overflow drain,would it wash off after it hardens?

Ninzerbean (author)  ElvenChild6 months ago

Yes, it would wash away. You can still put it outside but in protected areas. It won't last as long but it can't hurt.

I live in northwest Florida (with the big roaches.)

I have two thoughts to contribute:

1. poisonless kill on sight: a single shot of soapy water in a spray bottle will kill roaches in 10-20 seconds.
dawn handsoap works fine. twist the knob till the stream begins to turn
into spray and mix enough soap that the spray turns into a very runny

2. if your roach killing blobs are drying out too quickly and
not attracting roaches anymore, try coating them with glycerin, it's a
humectant meaning it absorbs water from the air to keep things moist as
well as stop evaporation from inside the main body. it is also anti bacteria and antifungal because it can't be broken down enzymatically. it's also non-toxic (and a
sugar substitute for diabetics and in dental safe chewing gum) wal-mart carries it in 6oz bottles as a skin emollient which should last you several years if you are making them every 6 months or so.

Hi Ninzerbean

I am still struggling with your formula. I like the ease of preparing it and setting it up. But the little german roaches don't seem to fall for this trap. I have tried honey, pancake syrup and peanut butter so far. Maybe I should try corn syrup. Maybe I should also add some oil like olive oil. As for doing it up all over the place, I do that painful work, but the results have been unsuccessful. Any new thoughts welcome. Thanks.

Hi Ninzerbean! We just moved into an older house about two months ago and we started seeing dead american roaches in our dining room (not really sure why they were dead but i was totally okay with it). So we hired an exterminator about two weeks ago and now our problem seems worse! They are now in our living room! We have two young children and the thought of roaches all around their toys...ewww. So my husband and I are going to try to take care of the problem ourselves but I wanted to ask you some things first: Since these are American Roaches should we still apply it in the walls if they live outside? Also, we have only seen them in our kitchen and now in our living room, should we put the bait everywhere or would that just attract them to the rooms we havent seen them in? I feel so helpless after hiring a "professional" and it getting worse.

Ninzerbean (author)  gracefam727 months ago
The thing is that the buggers are like bees, they talk to each other. Using my baiting system lets them take the bait back to the colony (and you really don't want to ever see one, I have and I wish I had not) and then they communicate to the others not to go to your house any more. There seems to have been numerous complaints with electronics, and especially PS3 players. Did you bring one with you by any chance, or recently buy a used one? It seems that they like to live in electronics and window/wall unit air conditioners. My guess is that is is warm, safe and well I don't know what else seems to attract them. Also dishwashers. Yuk. I would suggest that you cancel the exterminator for various reasons that I have written about in the 'ible. They really only stay in business if you see roaches. Success makes you fire them, it's so obvious when you think about it. Be really thorough when you do the baiting, it's the only way. It takes a long time, but you won't have to do it again for years and years.

I'm going to do this today but I have a few questions:
Does the electricity to outlets need to be cut off before removing the faceplates?
Will this roach bait attract mice or rats with the sweet smell? I just saw a giant rat scurry across my neighbor's patio and I don't want to bait my house with stuff to kill roaches that will attract the mice and rats to move in. I hate this. I can't handle roaches and critters. It has me thoroughly freaked-I can't handle going into my kitchen at night for fear of seeing a roach. My anxiety is too high over this and I'm in the middle of college finals, but I have to take a day to deal with this.
Also, thank you so much for making this intructable. I'm a broke college student and can't afford an exterminator-although now that I've read your story, I understand it wouldn't have helped for the long term anyhow.
Ninzerbean (author)  acline28 months ago

Acline2, sorry for the late reply, I had a zillion things going on, Ok first off it's totally against codes to put this stuff in the faceplates, that said, there are few other ways to get it inside your walls. Obviously don't use anything metal to put it in, but no, you don't have to turn off the juice. Rats and mice will not be affected by this mixture - it only is poison to things that wear their skeletons on the outside of their bodies. But I also don't think they will be attracted to it, well actually I don't know, but in all the years I have been using it I have never heard or anyone having that as a resulting issue. Good luck on your finals, I totally understand where you are coming from, it's going to be OK.

Thanks and this worked like a charm! It only took about 24-48 hours before the adults were gone. Every once and while I'd see babies, but I was unable to find the egg sacks <gag>. Also, I had previously read that the babies can only eat soft stuff and that's why they eat adult roach feces <gag>, however I wasn't seeing any adults anymore, so I'd put out a dollop (about the size of a dime) of this mixture on several post-it notes and laid them out around the kitchen at night (I couldn't leave them out because I have a dog, plus it would have hardened). Consequently, it only took about 2 more weeks and there were no more babies to be found! They loved this stuff! At the risk of sounding gross, I'd flip on the kitchen light at night and the teeny baby roaches were chowing down on this paste. Thanks again for making this! It is inexpensive, easy to use, effective and convenient!
Ninzerbean (author)  acline27 months ago

Great news and a great tip - thank you!

acline28 months ago
I did this yesterday and added a few tablespoons of olive oil so it will stay moist. Also, I found 100% pure boric acid for $2 at Dollar General. So, you don't have to go to a hardware store for 98% boric acid if you have Dollar General stores near you. They also sell light corn syrup (the same thing as Karo syrup) for $1.25.
boneyabba8 months ago

Hi Ninzerbean! Great article. Questions- I read that the paste still works after it hardens... if that is the case does it matter if you use something with oil or not? Before I found your article I made two rounds with just water, flour, sugar, borax. The first round I spread on a cookie sheet and let dry then spread the clods around- many dead roaches for days after. Still saw some roaches though so I made another batch- this batch I spread around in batter form... couple deaders- several live. I went to make a third batch, but noticed I've still got clods and dried batter paste from both batches around- which makes me think I should still be finding dead ones... Thoughts?

chennaiman10 months ago

I am in India and have the German roaches troubling us.Its heartening to know you have done so much work to eliminate the roaches. I want to try your method. Since Karo syrup is not available can I use honey instead? Or, should I try peanut butter for results? I will keep you posted on the results.

Ninzerbean (author)  chennaiman10 months ago
I think peanut butter. Because of the oil that will keep the bait softer longer. But now that it will smell good be sure to put it in places that little kids or dogs won't get to. It would be harmless in such a small dose of course, but why take chances.

And of course honey will work just fine, why not add a little edible oil to the honey because the honey is so thick. If you add water to thin the honey it sets up too fast.

Thanks for writing and keep me posted, we may all learn from what you share. I just can't believe that when I die that this will be my legacy.

Hi.. Thanks for your response. Day 1 has passed but no results so far. I used honey instead of Karo, Maple syrup or Peanut butter as these are very expensive here. I am hoping to see results soon.

Ninzerbean (author)  chennaiman9 months ago

It's been 21 days - how is it going?

Hi....For some reason, honey with boric acid powder and rice flour seems to have minimal effect on roaches. There seems to be a population explosion suddenly. Am wondering if you can give me any ideas. It is frustrating but I am patient. The roaches are slowly spreading out.

Ninzerbean (author)  chennaiman9 months ago

I wish I was there to see what you are doing, it's sort of confusing to me about how you have baited so many times with a variety of baits - this should only be a once every few years thing to do. When you write that you have "set up" the bait again it makes me wonder how and why you have to do this. Once the bait is in all the places - under the sink, on top of doors, near water pipes, behind drawers etc., that is it. It does take quite a long to time to do a place properly - about 4 hours for an average size home. Unscrewing all the switchplates and putting them back on is the reason. But when you say the bait was flakey... well it won't stick to anything if it is flaky, so how can you use it? The ratio of powder to liquid is to get a peanut butter consistency, so you add more or less liquid to get that consistency.

Chennaiman, are you reading all the steps to the 'ible? Sometimes people think there is one one or two steps because they have not selected the button to "see all steps on one page". Could that be the problem?

German roaches are very difficult to get rid of, there is something wrong with the comments on the 'ibles right now so you can't read the 400+ comments that used to be here, there was so much info and it's sad it is gone, but you have to get rid of all the roaches you see to start with if you have German ones, they are different in that they live inside vs outside like the regular ones we have in the US, the giant ones. You have to be more vigilant with the vacuum everyday, maybe set off a gas canister, get rid of all the cardboard, find out where they are living in your house (they love video game players) and attack that area. I think with an infestation such as yours (German ones) you may need more help than I can give you with my bait. That is why I wish the comments would come back, they are working on it but it's a low priority. People had shared great ideas there. I don't know what else to do.

​The bait worked in the kitchen but to a limited extent only. I had used boric acid powder, rice flour and honey. There are a few ones still moving around after 3 weeks. I cleaned up the mess regularly. Last evening, I have set up the bait again but used peanut butter instead of honey. But I have not got the jelly type consistency with it. Its kind of dry and flaky. Will wait and share developments.

We just moved into this home Jan and I started noticing signs of roaches pretty soon after. Roach feces all in cabinets ( which I thought was just dirt at first as I have never had issues with roaches to this extent until now), a dead roach a day in the kitchen along with 2 live ones on different occasions, also found some old egg cases in the cabinets about a week ago. I am not sure if they were here with the last tenants or if they invaded in between while the house was dark and vacant. The house was clean ( or so we thought) when we arrived but after I decided to pull out the appliances I realized it wasn't so clean. The housing office has been working with me. I found some huge gaps that lead to inaccessible open dark spaces in our bottom kitchen cabinets. I believe that is where some were hanging out so they came out and sealed off those large gaps.. I have also been using the foam anywhere I can. I have become obsessed and have realized I have a fear of these things! I do not have the German ones but the American ones and I had read where they prefer feasting on organic matter. I found some feces in my daughters clothing drawers. It is a very old piece so I am sure they are loving it. Your concoction: I came across this a few weeks ago and decided to give this a try a few days ago. I did not have the roach prufe but I had hot shot powder which contains 99% boric acid so that is what I used. I put the stuff everywhere! I cleaned out all my cabinets from roach poo, keep my house spotless, used the foam and thought I had sealed up all the gaps. I was hoping that would solve it but this morning I found fresh poo in my cabinets.. I am hoping that the hot shot stuff will work, if it doesn't I may go get the roach prufe and do it all over again. I am thinking it may take time for this to work, depending on how many are lurking around here. How long did it take for you to be rid if them? I'm sorry if this was answered in a previous comment, I am going to start searching through them now, just needed to get this out! I told my husband he may have to commit me! Lol!
Ninzerbean (author)  Sjc08589 months ago
There is a problem with the comment section of 'ibles and so you will only be able to go back 4 months which is a shame because there were over 400 comments. But anyway we will figure this out. OK, I just have to ask these questions - did you put the bait in all the places I suggest? Are you looking at all the steps of the 'ible? The stuff you used sounds like it should be just fine - you did mix it up with the flour and syrup right? You need to do a really big cleaning and get rid of the egg cases that could be anywhere. Vacuum every day for a while. This should work in about 24 hours. There should not be any live ones running around the way you are having them. There must be another egress into your place.

Many people have reported to me that the roaches are living in their playstation things. Check that our if you have one. They like warm places.

There just has to be something you are missing, this should not be happening. Do you have carpets? Could they be under the carpets? Put bait there. I really don't think you have to use Roach Pruf .

I know how you feel, I really do, I wish there was something else I could suggest. But this will get better. Keep in touch.
Thanks for your prompt response. Yes, I followed the recipe using flour and maple syrup. I had to use a little more syrup to get the consistency and I put it everywhere you suggested. I really think the brown banded ones are coming from the old dresser I have since that is the direction they were headed from and I found some poo in their recently. Gonna take out all her clothes, wash them and put them elsewhere. I think I should treat the dresser real well. I feel like we should just bomb this whole place but I am sure our exterminator will not want to do that. I thought they might be under the carpets as well and brought that up to the exterminator. He wasn't sold. We will see.:/
Ninzerbean (author)  Sjc08589 months ago

Just keep in mind that your exterminator does not want to get rid of your roaches or he will be out of a job. You can bomb the place yourself, that is easy, sometimes it is necessary too. But really training the roaches to think of your place as a death trap and telling all their buddies is the key. When they bring the bait back to where they live they will spread the message. They are sort of like bees that way.

True. I'm hoping that what you described is happening right now since I put the bait out this week and those little roaches were pretty small so I am guessing those egg casings were there before I baited. I know those brown banded prefer organic matter but am hopeful they will at least nibble on that stuff! I may have to bomb. I have never done that before. Will I have to wash everything I own after the fact? So exhausted! Lol! The one positive thing is I have massively de-cluttered and continue to do so. Though I am on the verge of throwing everything out at this point. Ha! Never knew what a nightmare this could be. Thank you again for taking time to help! Really appreciate it!
Sjc0858 Sjc08589 months ago
So we fumigated this past weekend. We spent about $50 and put cans all around the house to include the garage and attic. I expected to find dead roaches everywhere upon return but only found about 5 dead babies and a couple of silver fish. We have been thinking that the roaches were hanging out in the walls and attic so hopefully it killed them. Since last weekend I haven't seen a single roach or feces. I am hopeful but afraid to state we are rid of them as of yet.:)
Ninzerbean (author)  Sjc08589 months ago

That's a good sign. Sometimes it takes extra measures to get control, but once you do then the bait will be all you need and it should last for years. Congrats!

Sjc0858 Sjc08589 months ago
K, right after posting this I went into my daughters room and found 3 live baby brown banded roaches, one crawling on the wall and 2 on the carpet. I am just overwhelmed and over this mess.:(

HEY ! I am going to try this but let me tell u a little bit about my problem. I live in an apartment, the whole building has a roach problem. Now my kitchen is so infested they roam during the day, huge ones. My husband and I used to move all the furniture everything and start killing them, once a month. When it came time to do it this time, we barely moved the fridge and we saw a glimpse of 40-50 in one spot. It was horrendous, we couldn't kill that many because we noticed that every time we kill 20-30 it doubles. So we left them and decided to look for an alternative. We found this and we are going to try it, now my only question is, do I leave some of this in a bowl next to the fridge or do I leave some near a wall? I'm really hoping this work. We are moving in about 3 months but it seems like an eternity!

Ninzerbean (author)  dlo169 months ago
Well I guess you could leave some in a bowl, or put it on some cardboard so you can throw it out later on. You probably won't want to clean that bowl - also, the bait gets so hard it would be really difficult to clean. If possible you could post a link or just put up a sign in the building that says to go to "No More Roaches" so everyone could join the fight. Be sure to hit the button that says to see all the steps on one page so you don't miss any, and tell everyone else that as well. This could be a great way to meet your neighbors that you are moving away from anyhow... still. For a problem as big as yours is, it might be best to bomb the apt first. Keep in touch and let me know how it goes.

I just want to say that yes, this does in fact WORK! along with sweeping up, wiping down countertops and drying out the sink every night before bed the treats did work for me. haven't seen a roach NOT ONE SINGLE ROACH for 3 weeks or more now!!! can't express how nice it is to have my kitchen back! personally, I put out fresh "treats" every other night on post it notes and put them all over the kitchen (while singing COME N GET IT YALL ITS SUPPER TIME LOL) but instead of the flour and stuff I used BBQ sauce with a dab of water (as to not dry fast) and good helping of boric acid. you did an excellent job on your ible and I thank you for putting it out there! I did fumigate before going to work one morning (not the fogger, the fumigator has more % of killing power and is not messy) but after cleaning up the dead roach massacre I still saw them but just stayed with my game face on and gave them the BBQ treats. just keep dishes done, sink wiped (even sprinkled boric in sink too before bed), and sweep n stuff n ya should be good (: thx again instructables!

Hi, I made this mixture and put dabs of it all over my apartment. It's been about 3 weeks and I have seen less roaches but still see baby and adult roaches. My question is does the mixture still work even after it hardens. I noticed that it's so hard, it's even hard to get off if I try to take it off, I'm just worried it worked at first and now that it dried up it's not working. Thanks
Ninzerbean (author)  Jelei10 months ago
If you are still seeing roaches I have to wonder how thorough you were. When you say dabs all over did you follow the directions of putting it on waterpipes, behind kitchen drawers on top of doors etc? It takes a long time to do it right. There would be no reason to remove the dabs, and yes they get hard and they still work. But you must be really thorough the first time. If you miss spots - like not putting it in the walls etc you are really not making your house a place the roaches are going to tell their friends not to go to. Also, if you are seeing baby roaches you have existing egg cases, you need to vacuum everywhere and everything. Hope that helps.
Jelei Ninzerbean10 months ago
Thank you, I have got every spot you can think of except the inside of walls that's the tricky part how could I get inside the walls?
Ninzerbean (author)  Jelei10 months ago

It's not to code and all that, but did you read about taking off all the covers on the light switches and outlets? I fear many questions I get are because the whole 'ible is not being read. You have to click on the button to see all the steps on one page. Did you do that? That is really why the baiting takes as long as it does to do properly.

Jelei Ninzerbean10 months ago
Thank you I have read it again and will do the walls and hope that does the trick!
Jelei10 months ago
I added some under the sinks, on the pipes, on top of the door frames, behind Picture frames, under the fridge, oven, mirrors .. Everywhere it's just so frustrating because I have a 4 month old baby and wish they could go away and ofcourse the landlord got an exterminator but that hasn't worked.
nico670711 months ago
Hello Ninzerbean … I am seeing roaches (I think german type) at least 2 or 3 a day (1/2 Inch long) in my kitchen (counter) and only one marching on one of my bathroom's walls. I have spread Boric Acid behind my stove, refrigerator, corners, etc … I live in an apartment and I see that there could be many sources of the "infection." I saw a few roaches on the hall's floor and a couple more in the garbage room. I checked with my super and what their exterminator uses is a type of repelant … I think I made a mistake calling the exterminator …. this guy is using that stuff that does not really solve the problem … after his visit, I've been using pure boric acid but at this point I don't know who will die first, the roaches or me. I've been using that powder all over my 800 SF apartment. Another hypothesis I have is that the plague comes from the apt's heaters (this building was constructed in 1957) … my question to you is whether I can use your recipe inside hot places (thinking on putting the bait inside the heaters) … wouldn't it dry very quickly and lose any of its magic properties ? Other question, how long does it take to not to see any more roaches marching in my apt ? … is it matter of days or weeks ? ….. none of the commercially advertised products seemed to work either. Any other input will be really appreciated.

Thank you.
Ninzerbean (author)  nico670711 months ago
Well spreading boric acid around will only kill the roaches that run across it, and it won't harm you by the way, unless you have your skeleton on the outside of your body. But the bait is a way to attract them, plus you can stick it too anything. But the heat will not dry the bait up, instead it will melt. So that is not a good thing for the heater - is it the heater vents that you think they are coming through? Why? Over the years of being the roach person I have realized that the German ones are a lot harder to kill than my nemesis, the regular palmetto roach. But it is still do-able. You must read all 400+ comments though, well, just skim them until you find the ones that apply - there is a wealth of help there.
Keep me posted on your progress.
Oh yes, your last question, you will see results the next day. But keep in mind that it takes a long time to properly do a place, even 800 sq. ft. Make sure you are hitting the 'see all steps on one page' button so you are reading the whole 'ible.
Thanks Ninzerbean … Yes, I am thinking they come from the the heaters vents …. could it be possible ? I assume heaters provide them warm shelter and a place to reproduce. I am getting ready my arsenal to attack these unwanted visitors this weekend and I don't want to miss nor a single spot where they might hide.
Ninzerbean (author)  nico670711 months ago
Did you read the comment about the pasta water? Anyway, good luck!

Ok… here is my report. I applied the bait as indicated in the manual. I also applied pure acid boric under the refrigerator and dishwasher …. and since I had gotten caulking for cracks and crevices, I drilled some holes at some locations on my walls, large enough to introduce the tip of the boric acid container and easy to repair after injecting some acid into the walls. I also removed the covers of all outlets (and I found, of course, roach eggs) so I applied boric acid inside the electric boxes. Well, after 10 days… nor even one roach dead or alive (that part I don't get … nor even dead bodies?)…. so all of this brings me to think that I conquered my kitchen from the German domain. Now, I began seeing them in the bathroom (did de move?)… so I applied the bait all over the bathroom (doors frames, cabinets, behind the toilet) but for some weird reason the bait is ignored by the roaches. I see one roach every 3-4 days ( I hate them … so even 1 roach a month is an infestation for me) …. anyway, I got this product from Dupond (Advion) and I applied it all strategic points in my bathroom … let's see if it works. Keep you informed guys.

Ninzerbean (author)  nico670710 months ago

Nico6707, I am guessing that when you 'did' the whole house that you skipped the bathroom? Look, the thing with the boric acid powder is that is will not work in the same way at all - yes, if a roach runs across it it will die, but death is not what you want at first, you want the roaches to take the BAIT back to their colony to tell their friends not to go to your house. I can't stress enough pushing the button that lets you view all the steps on one page, that way you don't go off half cocked with less than the full amount of information. Injecting boric acid into your walls will not work in the long run, what you are going here is for the long run - if you do this right you will only have to do it every 2 or 3 or 4 years. Killing roaches is NOT the answer, you must bait them with the mixture so they go back to the colony to warn their friends. That is the only way this works. Poisons are just a quick (like a month) fix.

By mixing two poisons and my bait you are not going to have success because you need to BAIT the WHOLE house. If you kill a roach that doesn't get back to the colony, and you will kill them with the bait if they eat it at your house, you are setting yourself up to be infested again.

To think like a roach you must understand the colony they live in. They are not solitary monsters. Think bees. I wish you had only used the bait. If I were you I would sweep up all the power and put bait where you put the powder. Thank you for getting back to me, and also for trying to help that poor guy who obviously did not follow the 'ible.

One more thing…. I discovered that roaches came from my neighbors apartments …so I installed a door sweep and a whether seal around the frame of my door …. That helped a big deal too.

THIS DOESNT WORK. MY ROACHES DONT EVEN GO NEAR IT!!! I even just put the blue roach prufe down and they walk around it. I flung a couple of them in it manually and that was the only way. I still see a bunch. But mixing it with Kara etc is BS

I understand your frustration too… It might sound silly but it is also a psychologic war….. be prepare, be patient, be smart and respect the enemy … roaches are smart creatures … you just need to be one step ahead. Design a plan, determine what you will do, be clear on where the bait will be applied, keep records of when and where you applied baits … have a second plan working simultaneously (no repellants if

you use baits) …. once again, it sounds funny but think like a roach … where would you hide …. and and and DO NOT LOSE CONTROL !!!

Ninzerbean (author)  roachesarenotdying11 months ago

I would like to try to help you - it really does work. Did you read all the steps? Put it in all the right places as shown? Do you have German ones or regular? I don't benefit in anyway from this 'ible, I don't sell a product, have a website to link to. I just wanted to share what works for me because I have such a phobia of roaches. You are the first to dis the ible, so let's back up and see where you went wrong, or what happened exactly - so others may benefit from your experience. Did you actually mix up the bait or just use the blue roach prufe? I understand you are angry and frustrated, but lets see what went wrong, because this does work.

Georgemicheals11 months ago

I own a restaurant in a hotel the building is about 70 years old and all sudden 6months ago we became infested with German cockroaches. We've hired an exterminator but are still seeing about 30 a day. I'm worried they will start getting into the food or migrating out into the dining area. Is it even possible to get rid of them now that they moved in. I'm from Alberta Canada and roaches in a restaurant is completely unacceptable out here. Please Help

DWaghorn11 months ago

I've read most of the comments, but it's 2:00 a.m. and I'm tired so need to ask this question before I begin baiting tomorrow. I have a Dyson bagless vacuum. Once I've vacuumed, if I empty the cylinder into a bag and throw it in the trash, will that be OK, or will I set up a safe harbor for roaches in the canister of the vacuum? I'm thinking I should add some boric acid to the canister just in case. Please let me know what you think and thanks so much for all your hard work.

Ninzerbean (author)  DWaghorn11 months ago
Don't put boric acid powder in the vac. It will be fine to empty the vac into the garbage. I worry that you will be breathing the powder when it vents thru the vac, this would be very bad for you. Bad idea. You are welcome and don't worry, you will be fine, very soon. Once I had a window unit a/c, it was infested, I put it in a large garbage bag after I had dusted the whole thing with the boric acid powder. A week later it was still full of live roaches. They really have to eat the stuff.

Hello Ninzerbean!

I have a pretty bad roach problem at my parent's the point my boyfriend and I saw a baby roach once in a while crawling on our bed and today we saw a bigger one near our pillows. I'm horrified! We don't have sufficient funds to move out though. This place is a 16-17 year old neglected trailer and we're thinking about trying your instructable but I have some problem areas I'm worried about:

1) The fridge, we think that may be a homebase for them since the fridge is leaking something. I know there's an outlet behind there, but we're terrified of moving that fridge.

2) My counter/oven area. It's slightly separated from the oven, if I put it anywhere near/in the oven, would it affect food or cookery? Sometimes I see them crawling out of the small holes in the oven door.

I was wondering what your thoughts would be on this. I know you say cover every outlet covering, pipes, under areas, every nook and cranny. I fully agree but I'm really freaked out about what I'll find in those areas.

I understand how afraid you are, but before you bait you must move that fridge and have a strong vacuum and stomach ready. Get a neighbor to help, I have found that neighbors think it's really funny to be afraid of roaches and so they love to watch you scream, and that is why they help. I'm afraid the oven needs to be investigated before you bait as well. Because it is a small space and it does seem that there could be a nest inside I would suggest a b0mb of some type, then the helpful neighbor to move stuff, then bait. Good luck, it's going to be worse before it gets better. keep me posted on your progress.

I made my bait just like you said and i put it in a bunch of shot glasses around the house. I put a bit extra syrup but the same amount of roach prufe and flour. do you think that is sufficient? I still see roaches and i am wondering if they can find the bait or maybe they don't like it? lol I have used roach prufe before so i know it works but i am just wondering if the mixture is OK. like i said the only thing that i did that was different is add a bit more syrup because mine was very hard to mix.
Ninzerbean (author)  GP2M1 year ago
Sometimes I wonder if people have hit the "see all steps on one page" button. If you didn't see all the pages of the 'ible, perhaps this is why you put the bait in shot glasses. This won't work. Please go back and look at all the pics and read about where to place the bait. It is a paste for a really good reason - so you can put it on surfaces where roaches like to go. The amount of syrup is just the amount it takes to make a paste, that can vary by how much powdered stuff you are using. Put the shot glasses up in your attic or crawl space, they are not going to work. Sorry. That is why it takes so long to do a house properly.
No i didn't notice the "see all steps" button, thank you.
Ninzerbean (author)  GP2M1 year ago
This only dawned on me today, but I think it is why I get so many questions that are clearly explained in the 'ible. If you are a pro-member you automatically see everything - and there are no ads. This place is such a huge sharing of knowledge place, well worth the price to support it. Good luck to you!

Hi - I have an old home in south fl that was tented for termites 3 years ago and then largely renovated. Most walls & ceilings were opened and are new. All of kitchen and 2.5 baths are brand new. Never had any issues w pests, except a carpenter ant next - which seems to have moved but is still there - and silverfish. Not fond of chemicals so have up to last year only allowed dusting and barrier spraying by pest control. we still have the same issues they were here for so, stopped service 1 yr ago. We have installed, on a concrete platform and about 30ft from the house, a shed of plastic, with shelving and plastic containers to store things. Recently took out my plastic containers of christmas stuff and left it in the house for 24 hrs. Went to unpack on the deck and realized the containers were all infested with what look like american cockroaches - all ages and eggs. That night I found 2 flying roaches...killed them, sprayed (with ecosmart) and 2 nights later found another flying & killed. I have now bombed the shed, with all items inside. Found tons of dead roaches. Cleaned out this stuff as much as possible but worried about my house now having these roaches - do I need to bait the whole house (2400 sq ft) with your bait? I will def bait the entire shed - planning on tracing the vents and corner/floor crevices. Does that sound like a sufficient plan?
Ninzerbean (author)  radhaks1 year ago
Gosh, I don't know. It's a big job to do when I am not sure you have an actual problem. Lots of plastic bins have air holes and that is how the roaches probably got inside the ones in your shed. The fact that you now have roaches in your house but have killed the ones you saw would make me think it would be a wait and see sort of situation. This is such a busy time of year, I know you don't want to invest 4 hours into baiting your house when you are not sure - and I am not sure - yet, if you have a problem. It's always better to be safe than sorry of course, and if indeed you have roaches that didn't get killed you would be ahead of the game if you did bait. Personally, I would bait. But I have a phobia. I'm going to leave it up to you to decide. That's my 2 cents.
Thank you so much for your quick response. I too have a roach phobia & I wish I could turn back time & check those bins before taking them in!! I will bait the shed and maybe the area around where the bins were left inside (there is a huge potted plant right there)...see how that goes. I was also told to maybe fog the place, to be sure...just not excited to pack my kitchen up for a problem I might not have! Anyway - this is a very helpful site and will start w the shed. Thanks again for your thoughts!
Ninzerbean (author)  radhaks1 year ago
You are welcome. I am not a fan of fogging. It only kills the live ones and does nothing to alert the others not to come to your house the way the bait does. Read all the comments and you will learn more than you want to know, but they do help a lot.

Update r00_oo :)) After my initial post 11/4 the next day it seemed like the roaches were coming out everywhere in places i never saw them before .. we must have killed about 8 and a few babies... Then nothing for 3 days.. i was like WOOOOOOOOO there all gone then 2 every day for 2 days then another 3 days with NONE ..... now its one here and there maybe one every day then none again for a few days .....
Ninzerbean i was at the point where i just wanted to go and live in a hotel lol ..... i couldnt take it anymore i understand that feeling of not wanting to get out of bed. The first thing i do when i get home is look at the walls or if i open a clauset i inspect it first just incase. Hopefully a day will come when my husband and i are not sitting looking at the walls anticipating. We ripped out the kitchen what we found behind the cabinets gave me nightmares for weeks, but we cut off the water supply there now for 2 months ripped out the sheet rock and replaced it, foamed out all the water exits in the walls and left bait and boric powder behind the walls just incase. We are about to put in the new kitchen and i will get my caulk gun out again, caulk every cabinet.
We are halfway through the house now but i have baited everywhere apart from the garage. So my job this week is to go bait he garage and go round baiting what i might have missed first time around.
is that normal behaviour of dying roaches? wow i remember when we were killing 10+ a night and now its one here and there. I guess i am still getting a bit freaked when i see one incase they are re-grouping and starting up a new colony. i am going to put it outside of the house as well just to make sure... I cannot tell you the language i am using when i am baiting as there is a "be nice" comment policy here loooool ....
For a scottish girl living in NJ that never came across roaches before i think i am doing quite well with killing them and overcoming my bug phobia :)) ewwwwwwwwwwwww i hate hate hate hate roaches :(( ........ will i ever be able to just open a clauset again without checking it first.
Thanks for all the information .... I have read alot of the comments and there is some really good advice on here. Its also soooooooooo great to know you are not alone in the war of the roaches ....
Do you think it is safe to unpack yet?? all my stuff is still in bins in the garage :((

Ninzerbean (author)  r00_oo1 year ago
I'm just a bit worried with your wording - "boric powder". Boric powder is like washing soda, it's not the same thing as boric ACID powder. I'm hoping it's just a fast type and you are using boric acid powder, mixed with the yummy stuff that will make them eat it, it you think that having them just run across the powder is going to work - well it won't. They have to eat it and bring it back to the colony. Reassure me and let me know if you are doing it 'right', meaning the way I have it explained in the 'ible. Please.

So glad I found ur site. ... we moved into husband's moms house it was infested with roaches... we emptied it and we have bombed it and sprayed It to get rid of the load we could see... we had to move in sooner than expected and got here just over a week ago... we have ripped the house apart, ripped out the kitchen and the nest that was behind there was soooooo gross but all dead .... we have taken out the toilet and sinks to replace the sealers and stuff .... so we have begun to paint room by room as i go round the rooms i am painting it then baiting and caulking every hole crevis even in the clausets, doors, power switches plugs, cable holes windows.... if there is a hole or a split in the wood it gets caulked :)) we have also taken off every plate to expose the switches to replace them ......I am seriously getting BUGGED OUT eewwwww I hate roaches.... I made the bait and as we are going around decorating I am putting it everywhere before caulking... filling up holes in bathroom and kitchen with foam..... its going to take us quite a few weeks to get the place done its 4 bedroom ... will I keep going with what I am doing or bait the whole place?. .... because we are decorating I have my cute dog I didn't want to bait in some places because it would just come off and maybe the dog would get it...... since the initial cull.... we have been seeing some babies and young roaches about 4-5 a day... tonight i saw a big roach but it looked like a young roach compared to the ones that were here before. .... feel like I am winning loosing battle :((. .... plus I think I am allergic to them....... just feel grossed out every day its awful x x
Ninzerbean (author)  r00_oo1 year ago
Yes, it is awful, but you seem to be on the right track - at least you have an empty house to work with. I am just a bit worried that you are putting caulk over the bait - how will the roaches get to it? Put the bait up high so the dog can't reach it, make sure you put it behind (on the back of your kitchen drawers), no one can get to places like that. Even if your dog eats some it's not harmful to animals that don't have an external skeleton. I mean it's not great but inhaling it is much worse. The stuff won't come off, it's like really stuck on once it is stuck. And yes, it takes a long time to do it right but it is so worth it not to have to deal with the monsters for years. Remember to read all the comments - there is a lot to learn there from others, and look for wet or damp places - roaches like moisture, so be sure to look behind your washer and dryer pipes and bait there. Keep using that expanding foam - it's great for sealing up large gaps. Good luck, you will be fine and roach free very soon. I promise.

no i did not see that button, thanks actually just spayed only seen two more but that is it.
d4an61 year ago
Okay i found 10 really big roaches, like 6 behind a freezer , one on the counter, and one on the stove, it was at night. Have not seen any baby ones anywhere. killed all of them with spayed, how bad do you thing my infestation is? bomming tomorrrow and spayed to tonight, when you bait do you put alittle in a spot and how do it in the reciplcales? thanks
Ninzerbean (author)  d4an61 year ago
I don't think your infestation is that bad, but I am confused by your question because the 'ible details what you need to do to apply the bait - is it possible that you did not click the "see all the pages" button and only saw a small part of the 'ible? Reading all the comments here will also help, but really the instructions are all in the 'ible. Good luck, keep me posted.
Thank u so much. I have five month old baby. We have never had roaches but our neighbors did and were told if they didn't clean up they would be kicked out so they started moving lots of junk from around the outside of their trailer. I have seen 4 roaches and I am deathly afraid of bugs. I can't even kill them with my shoe, broom or spray. I have to leave the room. But the hubby is great he put this down inside and out ( also we put in our outside trash can). No more roaches! So thank u a million times over.

We are currently having a huge problem with these devils. We have had the pros out here twice and while they killed a ton of them, I'm still seeing live ones everywhere. We completely cleaned out the kitchen and put everything in boxes. It looks like we just moved in! We've been living this way for over a month now and still have bugs. Our house (an old schoolhouse) is a very old building and is over 4,000 square feet but mostly with solid concrete walls. We have three small walls that are sheetrock. Also the downstairs ceiling is that old time holey stuff. Anyway it means our ceiling is infested. Our kitchen is downstairs. I'm so beyond tired of fighting these evil creatures!!! I've read tons on the internet about getting rid of them and I keep seeing how sweet, sugary bait no longer attracts them. Is this the case for German species? That is what we have and with how long it will take to put this bait in a house this size I want to be sure to mix up the right stuff. Any and all advice will be GREATLY appreciated!! Oh and thanks for this instructable!!!
Ninzerbean (author)  jyeadon1 year ago
First thing - is all your stuff packed up in cardboard boxes by any chance? Get rid of all cardboard in the house, if it indeed looks like you just moved in you are actually providing them a place for their colony. Unlike palmetto bug cockroaches, the big brown or black ones, German roaches live inside - and worse - they procreate really fast. The big guys come inside and eat the bait and go back to the colony but the German ones live inside and they are simply from what I have learned here on this 'ible, harder to get rid of. The bait will still work but you must me more tenacious with other things too - get a service company, preferable a small one who does not have to abide my some crazy company policy to really help you. I could tell you tons more but really the best thing for you to do is read the hundreds of comments on this 'ible, you will have to go through lots of pages to do so. My readers are all trying to help each other and have shared so much. Good luck and get rid of the cardboard boxes. Keep in touch too with what happens, you will conquer them, it's just going to take more time with the German ones. It will take you about 5 hours or more to bait your house.
Yep, cardboard boxes...tons of 'em! The company we have been using is a small, hometown one. I hope that means they are doing everything they can to really get rid of them and not just keep themselves in business. They used several different things in the house (sprays and foggers), no baits though. I know one of the sprays they used is a kind of birth control stuff that is supposed to make the egg sacs unhatchable and I must say there really has been a significant decrease in babies. It just isn't complete! I still see babies now and then, when I want them GONE for good, ya know! I don't want to just keep it manageable, I want them all gone. These bug guys that told us to remove everything from every cabinet in the whole house and put it in boxes though, and they never mentioned cardboard being an issue. :(
I'm to the point now that I'm thinking of just really condensing things down and throwing out anything we don't absolutely need. That should pare things down enough to maybe just sit it all around and throw out all the boxes. I don't know. These things are a nightmare. I've been calling it my "War on Roaches"! I have read a lot of the comments here, but not all. I will take the time today to do that.
By the way, how we got them in the first place...just to help out others who might not know this is possible. We let a friend move in with us when she was down on her luck. She lived in an apartment building in Iowa (we are in Kansas) and with her belongings she had a computer and a tv set. It was less than a month later that I saw the first roach in the kitchen. When we started really looking around we found that both her computer and tv were so infested you could see the roach feces in piles inside both. :( So those suckers traveled all the way here from Iowa in her tiny car in the middle of December! When she got here, we left all her stuff out in her car over night. It was 20 Degrees F the day she moved in. So the cold didn't even kill them off.
Ninzerbean (author)  jyeadon1 year ago
Yep, those guys love electronics, you will read about a PS3 player I think it was, on here. They are very hard to kill because they can go so long without eating, freezing does not seem to faze them either. I think you can put your stuff in drawers and cupboards again, put some bay leaves in with your clothes. I have heard it helps, I used them but then again I don't have roaches - at the moment. Now that I live so far in the woods I bait more than I used to in the city. I see a dead one about every month, but that means I have not done enough baiting. Yes, it is a war. As far as cardboard goes, I try to put everything in giant ziplock bags. Especially stuff I don't use often such as cereal, taco shells, etc. Every type of flour goes into the freezer. You have got to put bait up in that ceiling. Lot's of it in different places.
As far as helping your friend - no good deed goes unpunished, right?
You don't want to sit the bait around though, put in the right places - up high, behind, inside, near water, behind your washer and dryer - sometimes the the holes they make to put the pipes and vents in are quite larger than they need to be, and do they seal them up? No. You have to do that.
Yes that is something I learned after the pros came in! I had no idea they were up high...all the spraying and powders I'd done on my own were at the floor baseboard areas and behind drawers and cabinets. I'm going to check all the holes too and put some sort of caulking in them. We are going out of town this weekend, but I'm going to start on Monday with this new plan. Get rid of cardboard and excessive junk, put foods in freezer and sealed containers, bait the house. I'll keep you posted on my progress. Thanks so much! Are you sure you don't want to just come stay a few weeks with me to help me battle!! LOL. ;)
Ninzerbean (author)  jyeadon1 year ago
You might want to fog up in the ceiling while you are gone. And, no, I don't want to help you - ha ha, I am so scared of the things my voice goes horse from screaming when I see one. I even made my son afraid of them.

Mixed up a batch using honey instead of syrup. It works but you have to add a bit of water, since the honey is too thick.
Unfortunately *someone* mistook it for me making a mess and patiently spent the whole day cleaning it out of all the nooks and crannies I hid it in. Going to mix up a new batch and put up signs. I'll add some green food coloring so people know it's poison.
Ninzerbean (author)  eilu1 year ago
Someone must think you are crazy.
I am soooo going to try this. I live in an eight unit apartment building...and every single time someone new moves in, seems like I see bugs. Usually in my bedroom...not the kitchen.
I had an idea to share with everyone.
I have an old meat infuser. (A syringe that you stick in meat to fill it with spices and such) and thought that would be perfect to stick into the walls where I have already put a nail in the wall to hang a picture. The infuser doesn't have a typical needle on it like a medical syringe. It flows out the sides, instead of the tip! Maybe make a batch that is a little bit thinner in consistency, and you could fill your walls up! lol! I am going to do it.
Ninzerbean (author)  natastrophy1 year ago
Excellent idea! Thanks for sharing.
We moved into a very, very old cottage in the Bahamas. We had to do the cleaning of the house and furniture when we moved in and guess what - roaches - American giant ones, german (baby and adults) everywhere - they seem shocked we were there. After a nervous breakdown, an exterminator came after a week of terror but it really did not do the trick. I found this instructable and this is what I did:

1. Clean the house decently including vacuuming and locating all of those nice egg casings ( wiped walls and base boards decently)
2. Two days of cleaning furniture (found dead giant roach inside the wicker) outside and decontaminating it with anti-bacterial
3. Vacuuming every single day
4. No food in house for one and 1/2 weeks. Any take-out food was in plastic bags at all times sealed.
5. Made your magic paste and put it everywhere just like you said. Wish I had left the container left over in the attic but I had not found the attic opening on the first run through. Put container outside behind the house where pets cannot access near water pipe into back apt.
6. Sadly, because it was so bad, we had to also spray Spectricide with residual. Sprayed the base of the house and all windows and sills; sprayed out buildings; sprayed base boards inside house (did not do cabinets in kitchen etc. because exterminator already did that). We also had to bait the kitchen with Tat and Combat but those went on the floor. The magic paste went everywhere else.
7. Sealed up between floor and wall where there were gaps; caulked the windows as best as possible (rotten wood old house nothing we can do - we do not own)
8. Two weeks after all of that - major change: Saw dead roaches but no alive ones.
9. It is now two and half months after that and we are still seeing dead german roaches.
10. Never saw them in the coffee maker or stove and we do not have a dishwasher. Have not seen them in the microwave. We live in a place where electricity is high so might I suggest what we do. We leave all electronics unplugged when not in use. I have to figure out how to check computers, t.v., cable box, phone etc.
11. In two and a half months, still seeing one/two dead roaches every few days.
12. Have not put clothes in drawers or shoes in closet yet because want to be able to check drawers and floors etc.
13. We cook in the house but we seal the garbage bag inside the trash can before going to bed.
14. There are tons of old cars in the yard right behind our house - would that be a roach place too? We can't do anything about those cars but maybe we could spray or bait the cars?

Some questions for the Board.

When can I feel comfortable about putting our clothes away without living in fear of a roach dead/alive in the drawers? I am going to keep the shoes in baskets for now so I can "see" the floors quickly. I am really freaked about the clothes in drawers.

Also, when can I ascertain that the problem is resolved? (I know this probably does not have a real answer). We do no see anything dead or alive for a week or so, and then a dead one.

We are also going to spray the house once per month since the directions stated the bait lasts two years. I am baiting the apt. next door since it is now empty and will then put the container in the attic as I can now access it. It is not that clean but I am too disgusted cleaning this house to do that one.

Note: I mixed boric acid with baby oil and killed a small drywood termite nest so this stuff is the real deal.

The Instructable was great and after arguing with my husband about the power of bait, I truly think that the spray helped the initial barrage but that the bait helped weed out the massive problem. I sure hope it lasts two years because baiting does take forever.
Ninzerbean (author)  cammylicious1 year ago
Wow, thank you for such detail on what you did, I am sure it will help others. The thing with the bait vs the spray is that the roaches live in colonies, huge colonies, and they need to take that bait back to their colony to feed roaches who are hanging out there, pretty soon they all know not to go to your house. If you kill them with spray they can't warn the others to stay away. Of course my bait kills the greedy ones who eat it at your house before they bring it back to the colony so you are going to see those dead ones. What you want to happen though if for the word to get out that your place and the apartment next to you are dead zones they must not go to. That was really smart of you to do the apartment while it is empty. The cars would certainly contain roaches, there are all sorts of yummy things to eat in old cars and it's dry there too. They need water but like to hang out in dry places. I think you are doing everything that can possible be done. I think you are safe to put your clothes in the drawers, there is no reason for them to go in the drawers anyway. Compared to how things were when you moved in I think your problem is basically over. German roaches are very hard to get rid of, harder than regular palmetto roaches. But please do the cabinets that the bug guy did, I swear what ever they use is not effective, they would go out of business if it was.

Tell me more about how you used the baby oil and boric acid to kill the termites, that sounds pretty dang interesting.

You could bait the cars too you know...

My kitchen is all ripped out and a new kitchen is going in, while the insulation and drywall are gone I am going to do a bang up job of putting bait on all the wood walls and studs. You would not believe how many dead roaches I found when we ripped the drywall off. The people before me (I'm in a new house from the one I did the 'ible in) had used a system where there were small tubes that ran all around the house put in when when it was built, periodically the exterminators would spray some poison into the terminals on the outside of the house. The result was that the house was infested when I moved in. But 10 months later, the contractor and I did not find one live roach in all the de-construction we did.
Ok we moved but NOT because of the roaches. Because we had no water. If you have a nest which many have many - you have to spray and bait. There will be that many of them. Bait for the later ones...spray for the get out now. And it cannot be raid. It needs to be a residual. Sorry Ninzergal! Sometimes you do need the bait and the spray.
Ninzerbean (author)  cammylicious1 year ago
Of course. I agree. There is not a "one size fits all". All of the experiences contribute to help for those in need. You have been a big help- thank you and stay in touch.

I used powdered roach pruf with a squeeze bottle and squirted in my top cabinets, behind the electrical plates, under the sink etc. about 20 years ago. I've also used it any time I have a wall open for remodeling etc. Other than spraying "Home Defense"(from Loews) around the exterior doors, I have very seldom had any infestations. The few I've had have been during very hot dry weather or very cold weather(not a common occurrence in Southwest Louisiana).

Before roach proof it was a constant battle to control them.
Ninzerbean (author)  dwighthe1 year ago
I made the bait because it is easier to get into more places and not get vacuumed up. You can't put the powder on the backs of kitchen drawers for example. But my solution started because I already had an infestation. It's good that you stay on top of them. I used the Home Defense from Lowes too, but the spiders and every other bug still hang out on the outside of my house. I wish there was a way to stop spiders from being everywhere.
ive made this paste/butter that you instructed above. and the roaches are actually coming out more its so gross. I feel like they're not dying. I have the little roaches about a inch big. and sometime we have 1 or two HUGE ones about 3 inches its so scary!!! but the little ones are everywhere. I live in a 2 BR apartment and we have a basement where I guessing most of them are and also a BIG hole behind the one counter in the kitchen which we didnt find till AFTER we moved in. ive put this stuff everywhere and they will not go away. im looking for a new apt. fast im scared they'll crawl on my on while he's sleeping. =[
Roaches get a bit active as they get poisoned. Also those big 3 inch ones aren't roaches. Well, sorta. They are in the roach family, but they can't lay eggs anywhere except under the bark of trees, so no real infestation. They just roam around and happen to come across a way into your home and just walk in. They will either die of old age or leave to reproduce.

Water bugs are actually American roaches and are a light brown but roughly the same size as the German version, but aren't as aggressive about reproducing as the German roaches, and well, they like to be around water.
German roaches are known as "house pets" as it's almost impossible to get them unless someone physically brings one into your house(or a close by neighbor has his house damaged in such a way as to make them want to leave, like roof caved in from storms or such) Being clean or dirty has nothing to do with it. If someone brings in a single pregnant female roach in a box or something you will have roaches.

So best advice to those that don't have them is to be very careful of what comes into your house, especially if it is coming from an apartment as they will spread all through it no matter who brought the first one in(apartments are all physically connected and roaches like to roam around)
Ninzerbean (author)  lordgarion5141 year ago
Thank you for your input - you have stated very clearly what I have been saying in bits and pieces.
Ninzerbean (author)  missdesireelynn1 year ago
You have to seal up that hole with some expanding foam. When there is a really bad infestation it will seem like it goes from bad to worse for a few days, then magically it's like all gone. But if you can find a new apartment at least you know what to look for this time and can put something in your lease about them, add bed bugs too. I have not had a problem with them but I hear they are very hard to get rid of. I wish I owned a pet anteater. I think they would be huge help not to mention they are one of the coolest animals I have ever seen.

i have seen between 1 to 4 1/4" sized dead american roaches in my bathroom every night. i have seen two live ones but they were not very active to get out of the light and away from me. i think those two may have been in the proccess of dying. not sure. i bomb my yard 2 times a year and keep the foundation and weep holes sprayed and filled with steel wool. i have caulked the pipes coming out of the wall and sprayed a along the walls. for the past few days i have had on and off times of finding dead ones. i think it may be getting better. not sure. i have put some hotshot bait in a few places but may put more in others. will the little ones just venture from outside to come in from the extream heat and little rain we have here in texas? i have yet to see a large one in the living areas of the house but a few big dead ones in the garage (i keep it clean and sprayed) i did find two large dead ones in a glue trap in the attic but thats it for the attic. there are two attic vents i think they came in thru. thats about where the glue traps are (thought i had mice at one time but was a squirrel). any other suggestions? thanks

Hi! It's been a week since we bombed the apartment after the blue goo paste didn't work. We were still seeing a few german cockroaches in the kitchen. After more Internet research, I bought bait gel advion and an IGR called gentrol on amazon: Cockroach Professional Pest Control Kit ~~ 2 Tubes Advion Roach Bait Gel w/ 1 plunger 30 grams per tube & 10 Gentrol Point Source IGR Insect Growth Regulator Discs ~~ Kill German, American, Australian, Smoky-Brown, Brown, Asian, and Brown-Banded species of cockroaches KIT1044

I put that down on Wednesday and so far haven't seen any bugs... Fingers crossed but it seems that these two products do work for German cockroaches. At least for now.

Thank you! I hope this helps everyone battling the German ones. I wonder what they use in Germany?

Update: I still have roaches, not as many. I have seen them come out of my table crevices. (eww).
The cracks and holes in this apartment is NUMEROUS, seems to be never ending! So I have been surfing through a lot of information. Ran across a comment that led me to Advion by DuPont used by pros. Using Amazon, I seen what others ordered with it. It's Gentrol IGR. (It will make the adults abort their eggs and sterilizes them!)
I figure I'll buy this. It cost as much as the caulk and foam I'll have to buy (knowing that I won't be able to seal all.)
Good news is these things absolutely know they are NOT welcomed. They are on the run. Faster than they were.
I'll post again once I get the stuff and give it time to work.
Have a good day!

Well you have your work cut out for you, sealing up the holes to get in and out is going to be a priority for awhile. I would even think you may want to bomb the place too. Thanks for the update.
IN REPLY to February 24 Ninzerbean (it won't let me reply through Reply button)

Ha ha! Would you not know this 100 year old cottage near the beach has roaches and dry wood termites? Just saw a rat crawl across the yard under the shed last week (but we have big dogs so those will definitely leave.....vermin and dogs/cats just do not mix thankfully)....... Well, we cannot rip out the cabinets and deal with tenting for termites in a rental soooo. Found out boric acid just kills all kinds of insects including drywood termites. I mixed the boric acid powder with baby oil so the baby oil would soak into the wood. I started in the areas where I could see kick out holes that drywood termites make and you see the pile of crap on the floor, window sill etc. That is where they are "active" and visible. I took a hammer and nail and made holes into all of the wood a few inches apart (and some more - might was well be thorough). Then I took a syringe (yip....needle and all - but a rubber medicine dropper that one never uses again will work) and filled it with the baby oil and boric acid and put it inside all of the holes where the kick outs were and where I saw rotten wood. The baby oil is so that the mixture will soak into the wood. NO more kickouts within an hour. (I was getting massive activity) Now drywood termites do move but I know one thing - tent this house all you want - all you are going to do is kill the ones that are there and you are right back to where one started in a month because termites are everywhere here. I did discover that if you soak/treat your wood used to construct anything in the house in a boric acid solution (so that your wood is basically also boric acid) you will never have a termite problem ever. Some guy from New Zealand says that is the only kind of wood they use there to build. Treated wood with boric acid.....sounds smart. Makes sense because on an Island - you just cannot get rid of termites. No way it is going to happen.

A side note for everyone. I did not have the attic sprayed with residual spray so will be baiting the attic; all outbuildings; and the cars. In fact, I might continue to just bait "surrounding my house" entirely also. I am on my very first week of no dead german roaches at all and it has been exactly 2 and one half months so I am pretty sure the bait is what did the trick (as well as my new love of caulk). We did not spray until a couple of weeks after we baited with the magic goo of doom. I forgot to mention that part. Now to bait the air conditioner and furnace etc.
Ninzerbean (author)  cammylicious1 year ago
Wow, impressive - you ought to write an ible on it! Thank you ever so much for all of your sharing, I'm pretty happy for you - and your love of caulk which made me laugh out loud.
Ninzerbean (author)  Ninzerbean1 year ago
Cammylicious, it's been 5 months, I'm just checking to see how you are doing. Anything to report?
jodog811 year ago
Been at war with them for a day! The population exploded after the recent spray by land lords. They crawled through the walls from the neighbors' about a year ago. I'm sick of them!! Apt. looks a war zone. I bombed them yesterday morning. Came back with residual spray and cleaning everything. Then noticed I need to seal things up. So back to "wally world" for some caulk. Killed 2 "generals" (eggs on them) and many many small troops. Nastiness, found 3 nests so far. (One was in a cabinet the day before they sprayed. Then found one Sat. on the fridge. Then another one last night in the cabinet above.) Been noticing some coming from the vents.
There is at least 2 species German and Banded.
Between the poisons and this recipe, maybe they will be gone! Please let me know if there is anything else I can do. Thanks.
Ninzerbean (author)  jodog811 year ago
Getting some spray foam to seal up underneath sinks between where the wall is and the pipes come in and the cutout for the plumbing parts of the sink drain and faucets. That seems to always be a place of egress because it is very open to the wall and sometimes even the outside. Also another spot to look out for an egress is where your dryer vent goes to the outside, sometimes these are put in very slap-dash and there is a bend or space for roaches to enter the wall cavity, not just your room where the dryer is but the wall cavity - from there they can go all over. Remember they have no bones, they can slide under and through just about the smallest crevice you can imagine. Read all 400+ comments, there is a wealth of information generous people have shared.

You must have all your foam-able places in your mind in advance because the can only lasts for a few hours tops. It's expensive and you want to try to use up the whole can at the time you 'open' it, or it just goes all hard and useless. If you use too much don't worry, you can cut the excess off with a bread knife or a box cutter after it is dry. Do not get it on your clothes, it never comes off. Same for your hair. You have to cut your hair. Obviously I learned the hard way on all this stuff.

Use that caulk to caulk under your baseboards and shoe or quarter round molding to seal the walls in your rooms. Wipe up excess with a damp rag. right away. Keep rinsing the rag so you are not wiping dirt into the caulk. Keep me posted on how you are doing. It is a war we can win.

It's not letting me reply under my original post. Ok so I killed so many of them last night, they just kept crawling out of the door and the wall. When I woke up today I knew I'd be killing them everywhere and I am! This is the grossest thing ever!! They are popping out and crawling around in the kitchen and living room. I don't know what to do other than kill every one I see but I know for every 1 I do see I'm sure hundreds more are hiding somewhere. I think I flushed them out of their nest and into the house. I talked to a guy about putting a new door on and he says he can probably get to it in a week or so. Should I go that route? How do you think I will get them all or will this be a long term fighting battle now that I disturbed their nest?
Ninzerbean (author)  brose71 year ago
This is a good news bad news story, good that you know where they are but bad for the obvious reasons. Your situation is horrible, can't you just go to Home Depot and buy a new door? Do you think they are in the walls of the house? If so I think you need to bomb or get professional help in getting rid of them, for sure you have a colony. Please keep me posted on what happens, I wish I could be of more help.
brose71 year ago
Ok I have a problem! I did the baiting like you said and have still been seeing roaches. We had them last year, fought for most of the year and hadn't seen them again until recently. Our pest company was just like well that's what happens. So today I went on a hunt to figure out what is going on here and I found the nest! After blood curdling screams and a serious panic attack I have collected myself a little better. Our back patio door has rotted wood and they just came pouring out of that area when the door would get closed (my husband was going in and out trying to grill) I sprayed the area really good with roach spray because there were roaches from teeny tiny to huge daddy roaches (Ive never seen them that big before, ever!) So now I'm not sure what to do. I want to rip the door out, treat inside the wall and then hang a new door. My husband says that's going to be too expensive and we can't afford it right now so he wants to just spray the wood and possibly rebait and then replace the door at the end of the year. The door was very crapily hung and secured to the frame. I'm also afraid once they get in there that theres going to be serious problems if we do take the door out. Can you please please tell me what you would do if you were in this situation? I'm not seeing tons of roaches IN the house, it was just one here or there, and then only at night but now its getting more frequent. Please give me some advice!
What if my sons friend brought a infested game system in my house and left it over night and now ive seen a cockroach in my kitchen the past week do I have a colony ????
Ninzerbean (author)  Freaked out1 year ago
I don't think so, colonies live outside, except for the German ones. Was it a small one? Have you tried a lot of vacuuming? Have you tried the bait? I don't have enough to go on here. Are you sure the game system was infested? Sometimes when I am feeling totally overwhelmed by outside forces that I have no control over I tend to blame others for what is happening, like you blaming the maybe infested game system, it could be a coincidence and you are just blaming the friend instead of doing something about the problem. I am not berating you - I'm just saying that I do the same thing myself sometimes. And sometimes even when it is not your mess or your fault you still have to clean it up, so to speak. But then it's done and over-with and you will laugh at how mad you were and it will be something you won't even remember 2 months from now.
Hi! I haven't gotten to the storage room yet but I wanted to update you a little on whats been happening. I decided to clean out the garage because that too had a lot of boxes and needed a good cleaning just to make sure that wasn't the source of the bugs.
After the garage, I completely cleaned my room out. I lined the walls with boric acid powder because I was too afraid of baiting in my room and attracting even more in there. Should I have baited it? I saw one baby one again tonight,walking in my room! Even after all the cleaning! Now I'm getting confused because I have no idea where they are coming from. I have a long glue trap that goes across my doorway because I am too scared to handle them, so there is no way it came from outside my room. I do have a few tiny holes in my wall from cables being put in for TV/internet/whatever access. Could that possibly be the source? If so, how can I prevent them from getting into the rooms without sealing the holes?
I'm so sorry for this long long comment. I am pretty scared right now because I am moving back to school in 3 weeks and don't want to risk bringing them with me!!! :( Thanks again for your response!!!!
Ninzerbean (author)  funkadelliec1 year ago
You can use a can of expanding foam to seal in the holes where the cable is coming in, you must use up the whole can in a few hours though or it goes bad, so find some other areas like underneath sinks to use it on. Do you have any electrical equipment in your room? Sometimes they live in there. It's warm, they like that. Stereo stuff, game consoles? a TV? You have to check it all out. Just pretend not to be scared for one hour and do a really thorough search. Before you go to school shake out all your clothes. As scared as I am of roaches, spiders make me scream until I am horse, but one time there was a huge spider in my son's room when we was in a crib, I had no choice to be be scared, no one else was home and no neighbors were awake at that hour, so I killed it. For me it was one of the bravest things I've done in awhile - to put that in perspective with all the crap that is going on around the world - that is pretty silly to think that killing a huge spider is brave. So put it into perspective to someone living in appalling conditions with no food and no family and no dog and you will fill feel that a small bug is really nothing to get the better of you. How do you feel now? Better? Now go out there and step on some babies! Roaches that is. Do you think I could be an inspirational coach? Say yes. I hope you are laughing.
Can you use borax instead thats what i have i hate to go out and spend more money. I live in public housing and they will not help with these roaches i see them in my yard from people across from me that are moving they crawl thru my front door at night and i will see them in the trimming. And Housing tells me to spray around my door put bait in my trimming and thats it. They wont seal it off for me or anything!! I have spent soo much money on sprays bait stations and whatever else i'm a single mom of 3 and one of my kids are allergic to roaches has bad allergies&asthma been getting shots for 4yrs now! I stay up all night cant sleep thinking about em. Can you also put the bait in maintenance rooms with water heater and furnace is? Sorry this is soo long.
Ninzerbean (author)  sleepie10961 year ago
No, you can't use borax. It's not the same at all. I'm sorry about your situation with the housing people but I don't think there is much then can really do. Pest control companies have no interest in getting rid of bugs for more than 30 days. They don't even try to find the colonies. Boric acid only costs 6 to 9 US dollars to get a can of the stuff I used. It will last you for years. But you must put some type of physical barrier up so that they can't come into your house from under the door. They have no bones so they can get in to the smallest openings. Yes, you can put the bait in the maintenance rooms with the water heater and furnace. Reading all of the comments will help you too, you are not alone and other people have shared a lot of knowledge.
Hi! I followed your ingredients exactly (except using multi-purpose flour and maple syrup instead) and put it around my parents' condo last night (mostly around the sinks, wall cracks, toilets, room corners)

I haven't seen any big roaches since I have been staying here the past two months, but have seen roughly 3-4 baby ones everyday (most of which are already dead). It isn't an extremely severe infestation, but it definitely was enough to make me uncomfortable. I am also concerned that this situation may worsen quickly. I have a feeling there may be a nest in the room next to mine, which my parents have been using for storage (and it contains many cardboard boxes).

Would you suggest "bomming" the room before I begin cleaning it out? Also, since I am only seeing the baby ones, are there more specific spots you think would be effective in attracting them to the bait?

I really appreciate you reading and responding to all this feedback. It must be crazy but its so nice to know that someone out there who is (was!) dealing with this problem has a heart to help everyone else out. I know you say you're no expert, but you sure seem to know what to do ! :)
Ninzerbean (author)  funkadelliec1 year ago
Thanks, my mom thinks this is hysterical that as much as I hate these things I have become an 'expert' on them. Anyway back to you - I think you should bomb the room (but still, don't stay in the house when you do even just a room) with the boxes, that way there will be no scurrying to other rooms. And you should do the kitchen - pull out the drawers and put the bait behind them. If you do a really thorough job the first time you bait you won't have to do it again for years.
Whatever the problem is in your parents' place I think you have it under control because you are only seeing dead ones. With that room of cardboard it's possible they are coming out and eating the bait and dying, but it is likely that that is where they are coming from.
Good luck, keep me posted on what you find in that room. I'm curious.
slevin11 year ago
Please don't feel like you let me down! I think your bait recipe has to help more than the Combat and Raid things I was buying... and it's cheaper. I'll keep the board posted once the management bombs our apartment next week.
slevin11 year ago
Sorry for the confusion! Yep, used your special green goo bait. I put it behind drawers, on pipes, in any crack I could find, in corner joists in cabinets, in all the outlets and light switches, a dab on top of door frames. I wonder, do I need to put a strip across the entire back, side, and top of each cabinet? So far I've just put it in the corners. How thick do you think it should be applied?

BTW I've read through all 400+ comments over the last few days! They're oddly reassuring :)
Ninzerbean (author)  slevin11 year ago
OK good. The German guys, unlike the big yucky ones I had, live inside and they multiply a lot faster. Because the colony is inside they probably do not take the bait back 'home' to poison their mates. They probably just eat it on the spot then die. So because you can't poison the whole colony they are harder to get rid of. Cardboard is something you have to be diligent in getting out of the house.

I only put a dab on the top of the insides of my drawers, doors etc. Basically anywhere it would stick and be somewhat out of sight. Kinda thick, a small glob, about as thick as a pencil?

I feel like I am letting you down somehow, I don't have any more ideas on why you are still seeing live buggers. 400 comments - it is somewhat helpful to see what others have done - when I first wrote this years ago I did not know about German roaches and it is only from the comments that I have learned how insidious they are. I think doing a bomb will help get things under control and then the bait should keep things that way. Remember to vacuum vacuum vacuum - and check out your electrical stuff like stereos and game consoles, dishwashers - all those place that they like to live. You need to be constantly cleaning what the other people may have left behind. Good luck, keep me posted on your progress
slevin11 year ago
Help! We moved to an apartment building about a month ago. In the past 3 weeks we've seen 1-3 German roaches every day, usually in the kitchen near the sink. I baited 4 days ago, but am still seeing one or two roaches every morning. I just rebaited under the sink, cabinets, and on top of the cabinets. Hopefully this helps. The apartment management is bomming our place next weekend. Any advice? I've never had bugs before and they're haunting my dreams!
Ninzerbean (author)  slevin11 year ago
When you say you baited did you use my recipe? You can't just use it in isolated places, the whole house must be done. German roaches are a lot more difficult to get rid of than the one's I was plagued with but you just have to be more thorough. Reading through the comments here will help you tremendously. But at this stage I do not know if you used my bait or another product, if you sealed up all the holes with expanding foam, etc. Yes, it's very gross and it is terrible not to feel comfortable in your own home, but persevere and you will get there.
sluna541 year ago
for this recipe do you have amounts for a smaller batch please let me know thanks
Ninzerbean (author)  sluna541 year ago
Of course, any amount of boric acid mixed with a bit of flour (because you want the roaches to be attracted to the bait) and enough syrup to make a paste. The syrup is to entice them also, so don't use water, that makes it too hard to nibble on.
skraw1 year ago
I'm sorry, but I don't understand how to "bait"
I'm definitely going to try these as soon as I know how to bait :)
skraw skraw1 year ago
Ha! never mind after reading many of the comments I now understand how to bait, so tomorrow I will try this. Though, I am scared to go in the small attic of our upstair bedroom where we spotted about eight big roaches. Our house is four years old and for the past month my son started complaining about having to kill one or two until a few nights ago when he killed three big ones and the next morning he was awaking by one crawling on him, soooo... that's when we found a "nest" in the attic
Ninzerbean (author)  skraw1 year ago
Skraw, you have to to upstairs to the attic, you have to, you can do it. Or enlist a neighbor's help, a great way to meet your neighbors. They will either help or they won't - I've found both kinds but you have to get the bait up there. "Bait" can be both a verb and a noun.
Hello everyone. I just made the special sauce and the consistency was a little different than described. More of a goo than a paste. Plenty of boric acid in there, though. Maybe 3 parts boric acid to 2 parts flour with a good helping of maple syrup (had trouble getting the syrup to mix in, I don't think it's pure maple syrup but it's all I had access to). It's pretty viscous, but definitely wouldn't call it a paste. Do you think it will still work?
Ninzerbean (author)  lucasmklaus1 year ago
Just add some more flour - I made mine too much of a goo one time and it dripped everywhere for days.
ashx981 year ago
I did this 2 days ago and I still see a couple of roaches. Anytime I could do?
ashx98 ashx981 year ago
Ninzerbean (author)  ashx981 year ago
If the roaches are dead this is normal, if they are alive this not what you should be seeing. Reading all of the 300+ comments will be of invaluable help. But mostly being sure you did a complete job. It takes hours to do a normal-sized 2 bedroom house. Are you sure you did a really thorough job? If not then do it again. Keep me posted on your progress.
Saw a couple roaches in the kitchen today so today so I made up a batch of this roach paste, it's so tasty I ended up eating half of it myself so I don't have much left, but I will let you know if it works.
Good thing it takes more boric acid to kill you than salt.  (source)

Ninzerbean (author)  tgrsam211 year ago
My mom thinks it's hysterical.
tgrsam211 year ago
Well! I live in an apartment complex on the 3rd floor so I am basically surrounded by other apartments. I tried this back in Nov/Dec and hadn't seen any roaches since then. (I was so freaked out back then I was posting a million times a day it seemed..I would pick up a grain of rice off the counter and go "OMG IS THIS A ROACH EGG???" Until I finally saw one for real and facepalmed. Once you see a real will never forget! )

I ended up getting a puppy (about 4 months ago) and scraped some of the more accessible goo up so he can't eat it. I know you say your pets leave them alone but mine is a big doofus and eats anything he can get his mouth on. Well, just last night I found a dead one on the bathroom floor. It was tiny. teeeeenny a little bit bigger than a grain of rice (we eat a lot of rice...) I haven't had a single one since I put the stuff down (about 8 months ago.) Do you think it is just time for a redo because I scraped it up? The stuff behind the cabinets and drawers and what not are still there...I just had a couple spots like behind the toilet that he could reach. Does this stuff expire? Or is it possible that they were just testing me to see if I was vulnerable again? We've had tons of rain...almost every single day...we even had a lot of flooding in the area about 2 days ago - some coworkers living on the first floor of a different apartment complex lost everything! Could it be that they are just being driven inside because of all the water? We don't have any other signs of them and I have been unable to sleep lately so I am constantly up and doing things around the house at 2am and haven't seen a single one. This one tiny one in the bathroom is the first in 8-9 months. I was curious if I needed to make up a new batch or if it might just be a fluke. Thanks for the info! I'll keep an eye out for any more just in case.
Ninzerbean (author)  tgrsam211 year ago
I think it was the rain. A fluke, besides he was dead so you know the stuff is still working. For a person who hates roaches (me) I sure seem to the go to person for information about them. Sort of ironic. Anyway, the rain can do it for sure, and even though your bait is still good you may see more dead ones because of the rain. Don't worry, they will go away after the rain sinks in. The colony is probably swamped so they have to re-group first.

Hi! Thanks for this - excited to give it a go. Disgusting infestation right now!!! Will this work with ants and mice too?
Ninzerbean (author)  luv2learn1 year ago
Ants yes, mice no. Their skeletons are on the inside.
