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.

Update: By the time I moved from this home the roaches stayed gone for 6 years, I baited one more time inbetween. It is important to hit the button that says to 'view all steps on one page' or you will think that this 'ible is only one step long - it is 8 steps long. Be sure to read all of the steps before asking questions. Other questions you might have will be answered in the comment section.

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 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 (any flour will do) 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. If you don't get finished baiting in one day put the bowl into the fridge, covered, and it will stay workable for another day or two.

*(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). Also, commenter ScottP6 says he was able to buy boric acid on Amazon for $7 for a pound. That is enough to share with neighbors and friends for years.

we lost our house and had no roaches. I had never seen one ever! Then we moved into a rental house and all of a sudden I saw them everywhere. We left that house and moved into another rental house. This 2nd rental had a worse infestation plus what we brought and we stayed there only 5 months. Now we bought a house again and I am over run. I wanted to call pest company but hubby won't let me. I am going to try this, this weekend as I can't take it/them anymore.

Karenmommy, if you think you brought some with you, you must find that item that they came in on. Game players, air conditioners, microwave ovens, anything basically that gets plugged in and is a bit warm and dry. If you have German roaches they live inside and are harder but not impossible to get rid of. The bait will keep them away but not until you get rid of the ones living in the house, so you must vacuum almost daily, you must get rid of all cardboard and use plastic to keep pasta or cereal or whatever the cardboard was in, in. Read the zillions of comments because there is a lot of helpful hints that might apply to your situation in particular. Good luck, keep us posted on your progress and best all congrats on having your own house again!
Hello and thank you for your response. They are in our couches and behind our stove and refrig and behind dishwasher. I have 3 messy little boys as well. I had been using chemical sprays that I bought online but they didn't work. I clean daily and just dread going I to my kitchen. I also found one or 2 in my bathroom. I had no idea they liked toothpaste. Yuck!!! I am a mom on a mission and will remove all cardboard (still have boxes from our recent move) and bait my entire house while keeping our cat and my kids safe.

Just an can get bulk boric acid powder on Amazon for really cheap and avoid paying the high prices of products that tout roach/ant control. You can get a pound for less than $7 (look under industrial/scientific not pest control when you search)

Ninzerbean (author)  ScottP610 hours ago
Thank you ScottP6, I will put that in the introduction. A pound will give you enough to give to your friends and neighbors too!

Here is the link...

I also want to say how wonderful it is that you take the time to keep answering questions here. So many people write something up never to revisit it again. You set the standard for how "how-tos" like this should be done! You are doing a really great thing and helping lots of people!! Thank you (I believe you can never hear someone say thanks too many times)

ScottP610 hours ago

I've always used the powder...but the other evening I saw one crawling along the top of the wall...<shudder> I am going all in on your bait method. I might make a video of how I do it following the authors instructions with loads of links and gratitude to this site (if the author is ok with that). I'm going to use unbleached flour (cause thats what I have)...I'm hoping for a 2-fer with ants as well!

One question: Is boric acid harmful to my dog if he accidentally is exposed to it? He's a 13lb mini dachshund.
Ninzerbean (author)  taral73 18 hours ago
I have 2 wiener dogs! I wouldn't want any dogs or animals to eat the bait but you are putting it in areas where there is no way for them to reach it unless they can open your bathroom cupboards and use tools to open switchplate covers. But the whole point of using this bait is to put it in places that roaches go, not where dogs or babies or cats or even people go. It sticks to horizontal places like the backs of kitchen drawers, places we don't even see much less go.
My concern is if I put it above door frames and it fell off he would find it and eat it because yes he eats ANYTHING! But, since you said it sticks well I won't worry about it too much. Also, I got a different boric acid than yours pictured, mine is actually 99%. Is that ok? And yay for weiner dogs, they rock!
We had none for 9 years now we have nasty neighbors and they are comming in. I am going to mix this up this weekend and apply it everywhere. I will not live like this. I just killed 4 of them in the kitchen that I just cleaned 2 hrs ago. I am putting my trust in you and doing what you say. I hope this works. Being a single mother I do not have the money to have someone come in and spray every couple months. I have ocd so my house is cleaned every day and night. Again I am putting my trust in your words.
Ninzerbean (author)  shannon.foraker18 hours ago
Shannon, it's going to work. Even if your neighbors are nasty I urge you to go to them and not insinuate that they might be the cause but urge them to do the same treatment, offer to share by mixing up a batch and bringing them half (but ask them about it first because it will get hard and unworkable in a day if left outside). Even if you can't get your neighbors onboard it will still work.

But you could go over and ask if they have a flat head screwdriver for your switchplate screws and tell them why you need it, like it is just you with the problem and you are just telling them what you are doing to solve it.
Hi we just moved out of a highly infested apartment. Where we live now there are no roaches of any kind. But......We brought em with us. I've killed about thirty this past week. Yeah that many. I've set traps and am cleaning every night. Not leaving n e signs of water. How effective is this and how long will it take to see results thank you !
Ninzerbean (author)  ladyofcesaryesterday
I am going to suggest that you read some of the 800 comments to get an idea of how effective this is and how long it takes to see results. Perhaps there in the comments you will see similarities of some other people in your situation and can therefor gage how long it will take, what it will take (getting rid of the objects you brought with you that are being used as a home for the colony) so that your question can be answered. I wish I could help you more than that but without more information about your situation I can only suggest that if you did not see your questions answered in the 'ible itself then the comment section would be where to look.

In need of that treatment asap!!!!!!! Tired of all these roaches crawling around everywhere! So emberrassing when guests come question is, is it safe to use it when you have a 1yr old and a 3 year old? How long will it take for the treatment to harden? Thank you!
Ninzerbean (author)  yatzi143 days ago
Unless your kids can open electrical outlets or pull open drawers to get behind them or above doors I think they will be safe. Sometimes it never gets hard, depends on the humidity. Good luck to you.
Very helpful. Thanks!!! (:

If I apply this solution, how long do you think it will take to start seeing results?

Personally, my cockroach problem has been kind of up an down. A year ago, there would occasionally be a cockroach at night every week or so in the garage/kitchen/living room/bathroom. Last winter, the problem kind of died down, and I didn't see any cockroaches for months. However, the problem is just now coming back. In the last 3 days, I've seen 2 cockroaches in the bathroom (1 in the early morning and 1 at night).

If it makes a difference, my house the gigantic cockroaches, not the little german ones.

Also, is there a need to apply the solution in the attic? I haven't been there for months -.-

Ninzerbean (author)  KyrieY11 days ago
Your roach problem does not seem too terrible so I would think that if you did a really good thorough job on baiting and did all of the steps and of course the attic, you would see results by the following day.

It does not matter if you have been to the attic or not, roaches live where you don't. Those are the places you need to bait. If there is stuff up in the attic for them to eat such as the glue on cardboard - they will be there. They actually don't care if you don't write or call, they have no shame in stalking you anyway.

Yes, get up there to that attic and bait away along with all the other places listed in step 7.

And good for you to take control of the situation before it gets worse. The warm weather and rain drives them inside and/or makes them more active. Go figure. Maybe they get bored like humans do.

Alright. Thanks for the advice!

One more thing. What is the purpose of the expandable foam insulation on the pipe? How necessary is it?

Ninzerbean (author)  KyrieY10 days ago

If you have gaps between your walls and the inside of things - most houses do - then use the foam to seal the gaps.

Once again thanks.

I've started the process of applying the bait, and I've run into a few more things now.

Yesterday, I started to put the bait in the places you mentioned, but I didn't finish because there were still places that weren't baited yet. As a result, I put the bait in the refrigerator over night, and I plan to finish the job today.

1. Will the bait still work if I apply it today? If it matters, it is still kind of sticky and seems like it can still be applied.

2. For my situation, is it necessary to put bait behind every single outlet cover and switch cover?

Ninzerbean (author)  KyrieY10 days ago

It's good that you put it in the fridge, it will be fine once it comes to room temp. It does get un useable after a few days 'cause it gets too hard. About doing your whole house and every outlet cover, you know what I am going to say don't you? There are only two ways to do things - the right way and the other way. So yes, you do have to do every one because you just don't know where they are living inside of your walls and where they can freely rome, so you have to do all of them to do the job right. The crew that did my house, it took 2 guys 4 hours, that is basically all they were doing was the outlets. Mind you that it is against all sorts of codes and be sure you are using a wooden popsicle stick and the power is turned off etc.

I've applied more bait around the house, and it seems like the situation is getting better, as I haven't seen any cockroaches in the bathroom for days. However, a little cockroach came out today at 9am in the living room today when the sun was already up. Should I be concerned?

Ninzerbean (author)  KyrieY5 days ago

I don't know, only you know if you put it everywhere you should in your house. You were debating the need to put it everywhere so I don't know if you really thought there was a need. Personally I just would not take chances. If you did a thorough job then I don't think you need to be concerned, but if not then yes, you should have some concerns. Did the roach seem healthy? Or near death? A 'little' one could mean a baby or a different breed. Vacuum daily for egg cases, get rid of cardboard, read the comments. It's a war you know, you don't want to let down your guard until they are all gone.

We are having to move from the apartment we have been living in for three years because it is INFESTED with german roaches. I know they are inside our electronics and one of our couches. My question is, can we take these items and use the bait to get rid of them? It sucks that our furniture has to be left behind because these nasty apartments are infested. I know for a fact it isn't just our apartment that has this problem. We have had the landlord gel the apartment and it didn't work. We have used baits, the ortho home defense from Home Depot and it is STILL infested. We move next weekend and we are worried we will somehow take them along to our new place. Any suggestions?
Hope I can help with this. I moved to Hawaii 2 months ago and have already seen more roaches here than I've even seen in all my life (zero). I spend all my days planning and preparing for my escape off this infested island when miliatry orders are up in 3yrs. So far this is my list:
(1) Get many, I mean A FRKN TON of airtight plastic storage bins (ZipLoc weathertight is a brand), it may end up costing, but its the way to go since roaches love to hide & lay eggs in the flaps & weaving of cardboard boxes.
(2) Tiny roaches will live & breed in the motors of appliances so toss them in plastic/garbage bags & store in freezer for a couple days before the move to freeze the life out of them!
(3) wash all your clothes, curtains & bed linens on the hottest setting (without damaging) and IMMEDIATELY move them from dryer into plastic bins so roaches wont have time to attach & hitch a ride.
(4) Those efficient little devils can feed off of the GLUE in your book bindings so throw all your office supplies, magazines, tampons, diapers, etc into the sealed bins with a roach bait station in every bin to feed & kill them & DONT open the bins for a few weeks, so that any placed eggs can hatch, feed & die also.
(5) Do a thorough cleaning of the new place before your stuff arrives, behind fridge & oven, etc then bring your stuff over & shake everything off outside! I know you'll worry what the neighbors think but at least they will see that you obviously are not comfortable living in filth & are taking measures to avoid another such situation. Wipe down & inspect everything before stocking shelves & cabinets & rewash all the linens again for good measure.
I wish you luck & cant wait to do this myslf in the roach-deterring snowy weather of NewEngland!
Ninzerbean (author)  NorEaster9 days ago

NorEaster, This is great advice for the german ones and I will refer folks to it. Thank you for taking the time to write. If we can get the whole world to do both of our methods we could seriously decimate the population, well maybe. Anyway I think I may copy and paste your comment into my 'ible - you don't mind right? Because in a month or so it will be a few page clicks away and I think it is sound advice that I don't want people to miss when reading the 'ible. Let me know, otherwise I can feature your comment which moves it to the top of the list of comments.

Ninzerbean (author)  jules08031 month ago

The bait will not work for your situation. You know where there are so you must get rid of them. But taking apart your electronics is going to be very very hard, and what if you leave an egg case behind? Your couch - wow, I don't know how you would be successful there. This is just terrible. I wish so much that I could help but this system is more about making your house or apartment free of roaches and more about the large non-German ones. You need not baits but a very strong vacuum. Baits are for luring roaches to the bait so they take it back to their colony and the other roaches then learn not to go to your house, but because you have them and know where there are and are not removing them physically, they will still be there. Somehow the situation must have gotten out of control and now... I think you should start over. But if you see even one single roach in your new place - which hopefully you will bait the day you move in, you will kill it right away.

sburton10910 days ago
We moved from a rent house that had a horrendous german cockroache infestation. And now in our new house it seems as though we have brought them with us. We tried so hard to bag everything, spray furniture down, throw away electronics... Had to buy all new appliances. It was a nightmare. But I've seen a few scurrying around recently after about 1 month here. Will this solution work for german cockroaches by chance?? I'm almost 8 months pregnant, have a 4 yr old as well & want to get rid of these guys before new baby arrives..
Ninzerbean (author)  sburton1099 days ago

Suburton109, it just shows how incredibly tenacious you have to be not to bring them with you, which I am not saying you did, but you might have. So, yes this works with germans but it is harder, the comments are a great source of help here on germans. It takes more work because they live inside vs. the one's I dealt with - the giant palmetto bug roach. With the germans is seems that you must find the colony and find it fast, you are very smart to know about the electronics. Vacuum all the time, maybe a shop vac so you don't have to go through expensive vac bags. But wear ear protection, the noise level is not safe on those shop vacs and in no time you will damage your hearing. I use hearing protection whenever I vacuum now and it's a central vac, not very loud except then using the nozzle on stuff. Also it is so much more relaxing to not hear the noise, but I am digressing. OK, back to you, the fact that you are pregnant and all, well the boric acid is safe for you to use but have your husband or SO mix it up, I say to wear a mask when mixing but really you can't be too careful when preggers. So you can be the one applying it, not a problem, it's the powder I am worried about you breathing...

so bottom line, yes it will work for the germans but you must be aggressive in finding out where they are living and get rid of the colony along with baiting to prevent future infestations. Good luck, you will be fine. But keep in touch, tell me if you indeed find a colony that you may have brought with you - your story is especially a learnable story because you were so tenacious when moving.

I am about to leave my house in the woods and move back to Ft Lauderdale and I dread finding a rental and probably finding roaches too.

I live in dorms at a college campus and my room got infested and now my boyfriend's is. He just recently got moved into a new room and we both think we saw a roach already. Since it is a confined area& theres rooms in the same building, would it be safe to put in the rooms? Theres no attic or anything but Im just wondering where i could put this?
Ninzerbean (author)  angelruthashley9 days ago
It is absolutely safe, put it in high places, behind things, dark places, it is so non toxic that it is safe. Just mix up a small batch. You might want to get other dorm dwellers involved too and it is a fun way to meet people. OK, not fun, but it is a way to meet people, and if you guys have the problem everyone may also have the problem.
Supermom8113 days ago
When the pest control company came out to your house when they were using this bait, did they do anything to find the colony and get rid of it? I definitely want to try this but it also gets me nervous to think that there is a colony living behind my fridge or oven that I would think we would need to get rid off first before putting out the bait? Is that necessary?
Ninzerbean (author)  Supermom8111 days ago
In my situation when they said "This is the worst infestation we have ever seen" there were hundreds living in the bottom of the oven, in a pull-out drawer. Yes, they knocked down the population tremendously before they baited. This was a rental house and it was just gross.
frozenshade17 days ago

I made this and am wondering if I perhaps did something wrong. It hardened up. Is it supposed to stay soft like peanut butter? It was soft the first day or two, but we live in Florida so wondering if heat and/or lack of humidity lately had something to do with it.

Ninzerbean (author)  frozenshade17 days ago
There is nothing wrong with it being hard, it usually gets hard after a day depending on the humidity. If you didn't get it all used up and/or finish your whole house though you will have to mix up another batch because you can't spread it around once it gets hard. Is that what you meant with your question or are you asking if it is alright to become hard once you have put it where you want to? Either way I think I have answered you, but if not ask again in a different way I guess.

Yes you answered my question. I wasnt sure if it was supposed to stay soft or not is all. Thought I may have done something wrong. Thankyou very much for getting back to me.

I just moved into an apartment 4 days ago and I think it's infested with small flying roaches. I first saw them on the night of day 2 in the kitchen. At least 3 that night, I only killed 1. They're telling me it's just water bugs and roaches don't fly. I've only seen them in the kitchen and a couple in the living room. Today I put boric acid all over the kitchen, window seals, front doorway and even some in the living room. I didn't come across this until after.. Do you think what I did will help? What do I do?
Ninzerbean (author)  Ballroomblitzz27 days ago
Roaches fly. Do you think I would seriously tell you that sprinkling boric acid all over your house would work if I spent the time and effort to write this 'ible and to answers questions every single week? While I enjoy helping other people rid their homes of roaches I do not enjoy having to deal with bizarrely inane questions such as yours. I apologize for being offensive but you deserve the truth.
Well, thank you for verifying that they fly. Sorry for wasting your time with my inane question.
Ninzerbean (author)  Ballroomblitzz26 days ago

Dear Ballroomblitzz, I did not read all of your question and I was rude to you. Let me start over and say that sprinkling the boric acid powder will get on the feet of the roaches that run over it and it will kill them, it will kill them probably before they can return to the colony. As a consequence there is only a short term gain and the opportunity to dissuade the colony from hanging out at your house is lost. I don't think you need to wipe it up or anything but it hurts more in the long run than helps. I am upset at being told all of my faults by the real estate broker who had listed my house yesterday. I had a former husband who did that frequently so you'd think I would be used to it but it turns out it still really hurts and I was very angry and I took it out on you. Please accept my apology for being rude.

Yeah your first response kinda bummed me out, not what I expected but I understand, thank you for getting back to me and apologizing. Hope you're having a better day today! Take care.

also you should take care to find out what kind of roaches you are dealing with. if you are dealing with german cockroaches (tiny, creepy, crawling on the wall by the tens and 20's) you may have trouble killing them since they tend to reproduce VERY quickly and by their numbers end up overrunning most of their natural predators except for house centipedes who love eating roaches but who also look creepy as hell. they also are very hardy when it comes to poisons. of course boric acid isn't a poison and thus they cannot build any immunity or resistance to it but at the most it will stunt their numbers. next you have the oriental roaches which are larger slower and seldom seen since they prefer to live around water. they generally walk on floors and have trouble making it up walls or on counters. american cockroaches are the third and they (as well as oriental cockroaches) prefer to live outdoors but both make their way into homes when they can. german roaches cannot fly so you are in luck. i had german cockroaches at an apartment once and i tried everything from sprays to boric acid to exterminators to diatomaceous earth. nothing made a dent. i eventually moved out. i recently moved into this apartment and found oriental cockroaches. laid down some boric acid bait stations and poured boric acid in every dark nook and cranny and had my neighboring apartments do the same. no more roaches going on 9 months now.

Awesome, thanks!

Sounds like your potion is effective and has helped so many people...kudos! I came across your Instructable after I found roaches under my house living on the fiberglass insulation between the floor joists. We had a small flood in our kitchen, and in order to dry our wood floors I went under the house to see if the insulation was wet. It was, so I pulled it all down and found live roaches living happily on top of the insulation. I know the water must be the attraction for them, but if we only had the water problem for a couple of weeks, I wonder if the roaches were there before? We will replace the insulation that was wet, but I'm afraid that roaches may have gotten to the other insulation as well. ? Replacing all of the insulation will be costly and doesn't promise to solve the roach issue. My question...what would you do in this situation? Thanks!!!

Ninzerbean (author)  Robin F1 month ago

Sorry that my response is late - there is a glitch with Instructables and I am not being notified of comments coming in. Anyway I hope I am not too late - there is no need to replace your insulation, the water attracted the roaches. They may have been there before, but replacing the insulation will have no effect on their being there now or later. You simply need to bait.

Awesome. I appreciate you responding and will bait away down there. The wet insulation is in bad shape so I will replace what looks damaged and bait at the same time. Thanks again for your help!

I read all steps multiple times before even attempting to try this. I am like you, cannot even open an encyclopedia with a bug photo in it. My husband and I bought our home several years ago and it is surrounded by trees and near a pond. I have never seen a roach before moving here. The yard is polluted with them, they are under every rock. Ewwwe! We saw 2 inside before we moved in and then never saw any more for a few years. It appears that they come in through the basement. I do not see them often but, it has been mor frequent in the last few years. I would rather die than call an exterminator. We live in a rural area where everyone would talk & think that you were just filthy pigs. Not true. After exhausting every idea, I came upon your intstructible. First of all, may God bless you for trying to help others! I followed your instructions to the letter at the beginning of October 2014. Never saw any after the 23rd of October. Then all of a sudden, they are coming back. First, I found a few dead ones. That was ok. Dead is good! Now, I have seen 2 live ones crawling in my living room on 2 different occasions. Do I need to repeat the process? It absolutely worked for 3 months. No exceptions. Why are they back now? Have you experienced this, or has anyone else? I trust your responses because you really do know what you are talking about. Please help me.

Ninzerbean (author)  Freakedout1 month ago

This can happen if there is a lot of rain and it drives the roaches inside to seek shelter, there is nothing you can do about it until they find the bait. Obviously they did not hear from the former roach residents of your house that your house is a bad place to be. As long as you baited your WHOLE house the bait should last for about 3 or 4 years before you would need to refresh it. Also maybe you brought something into the house that was infested? I did this myself with an item from a garage sale, ugh, gross, freaked out etc. I am sorry not to have gotten to your comment sooner - there seems to a be a glitch at Instructables and I am not getting notified of comments.

Also, if there are that many roaches around your house it might be a good idea to buy some products you can use outside to lessen the population - diatomaceous earth can be sprinkled around your yard. They hate that stuff. Wear a mask when you do the sprinkeling.

I really appreciate you responding. I agree, the rain totally complicates this issue. I am planning on treating outside as soon as the weather will cooperate. I will keep you updated. Again, thank you. You are helping a lot of people.

I was so excited to buy this product and get started on my road to clean happiness! !
But when I went to our local HARDWARE STORE they tell me ROACH PRUFE HAS BEEN DISCONTINUED! !!
What? !?
Everywhere? Probably worked TOO good and was putting Exterminator businesses OUT OF BUSINESS, is my guess.
So now please tell me. Will another brand of BORAC ACID WORK? This bottle says 100 percent, no coloring nor scents. I cannot live like this. It's exhausting to be bleaching DAY and NIGHT, be on top of everyone who comes into my apartment AND it's so embarrassing! ! Somebody HELP ME!
Ninzerbean (author)  lupeluu 1 month ago

There is a glitch at Instructables and I am not being notified of comments, so I'm sorry this response is late. Any product that is mostly boric acid will work. 97% - 100%, your common sense will lead you. Bleach is not something I would use in any way that you could be inhaling the fumes. It is very toxic and has no use in the bug war.

Hi there! So I just moved in with my dad in Vegas. I understand the heat but it's dry? I don't know. Anyways, there's the German cockroaches that came in with used furniture. A armoire and a used TV that was included. (Maybe that's why it was so cheap?) Not a lot bevause i rarely see them. Anyways, they leave us alone but still crawl on the tables, walls and in the cabinets in the kitchen. They don't bug me as much because I lived on a ranch near a pond where it was infested with the red and black ones that bite during the night. So as long as they stay away, I'm not too worried. And also the fact that we are moving next month because the landlady won't get rid of them. The couch and ottoman are being left because we know for a fact that's where they are. And everything that can be left, will be. So what my question is, even if we do happen to bring along 1 or 2 (or 3 or 4), think it would be effective to do this just as a kill them off at the beginning and hopefully prevent them from repopulating?
Ninzerbean (author)  katieh932 months ago
Absolutely. Yes, bait the next house you move to right away.

I have a question? When you say bait what does that mean? Your instructions just say mix the bait in the bowl and then put the bowl away when you are done. What do I actually do with the bait? Spread it all over the floor? Wipe it on the walls? I am sorry it just doesn't explain how to actually use the bait. Thanks!

Ninzerbean (author)  seans81 month ago

I think you are only seeing step one. Step seven is quite detailed about where to place the bait.

I'm sooo desperate to get rid of these filthy roaches that when I couldn't find Roach Prufe i bought some other brand that says it's 100 0/0 BORIC ACID. PLEASE tell me if I follow all steps to this recipe I too can be rid if these nasty roaches FOREVER! !
I bought 2 bottles and am going to make enough for ALL 8 (2 bedroom) apartments. Other wise I think theyd never REALLY. Go away, right?
I'm on my way home now to try this and I gotta tell you, I'm excited! !
I just moved in with my 9 year old grandson and it's ridiculous how I have to bleach morning noon and. Night!!

BTW, we do not see signs of roaches inside our house. We use Ortho Home Defense from Lowes on the base of the exterior and interior walls every few months and have been lucky not to have a problem...or so I thought!

I have a long trail of roach infestations in my lifetime. :( I am currently living in townhouse apartments that have a German Roach infestation. Needless to say, it is uncontrollable. I treat the apartment, but it does nothing to the amount that are in this entire building. After 3 long years in this horrid place, I am happy to say that I am moving to a HOUSE. A real house!

Only.... I'm not so happy anymore. We had seen the house initially and checked for roaches. Cabinets, sinks, stove, bathroom, refrigerator, top of closets and doors all clear! No feces and no roaches, dead or alive. We happily paid our security deposit and signed the 1 year lease! We have decided to leave behind all furniture except our mattress and dog crates, which we would clean and inspect very well before the move. Well, all was for not, my dear friends! We received the key and went to shampoo the carpets/clean over the house before moving anything in.... And behold!!! Roaches. A couple dead here.... A few babies there. And the fridge.... Pulled it out to a nest behind/in it. And they're German roaches! I wouldn't have expected anything else of course!

"Enough is enough! I'm sick and tired of these monkey fightin bugs in my monkey fightin life!" - edit of Samuel L. Jackson 'Snakes on a Plane'

^ Without the edits.... That's how I felt at this point. We brought this issue to the landlord immediately and showed him the fridge and other areas. He said he had never seen that many... maybe one or two babies here and there. *facepalm* When there are babies.... There are parents/adults. Common knowledge to mankind in general about all living species. Anyways, he agreed to have an exterminator come and treat the house. So a plus!

Only, anymore, that is only a temporary solution. I have witnessed that personally. So after the exterminator came (today), she said based on what she saw behind the fridge... It was a heavy infestation (yay!).

The house has been empty for 2 months which I hope has tamed them down some, and I plan on using this method to treat the entire house before moving anything over. Thank you for this informative and helpful post and all the wonderful comments! It means the world to people like me who can't seem to shake these disgusting bugs from my life! Wish me luck! ;)

Happy Baiting everyone!
Ninzerbean (author)  thumplover882 months ago
Happy Baiting Kate! I am glad you read the comments, though there are more than 700 there is a lot of knowledge there. Good luck, after all you have been through you really deserve to live roach-free forever. Keep us posted on your progress. Has the fridge been removed/replaced? From what I have learned on here used fridges can be the source of many problems.
I unplugged the fridge immediately when I found the nest (It was running since the power was on) and pulled it away from the wall. It has been treated and about 50 dead ones fell out of it when I went in after the exterminator had left. I flushed all dead roaches down the toilet that I found to ensure any egg sacs were not going to hatch. We plan on replacing the fridge as soon as our finances permit! I will definitely post any results I have within a week or two. :)
Ninzerbean (author)  thumplover882 months ago

Be careful if you replace it with a used one. You are very brave, 50 roaches would have had me running down the road.

So an update is in need! I baited the entire house upon moving in 2 weeks ago and have seen only 3 roaches since! My husband and I have been very clean and DRY with the kitchen/bathroom and have kept our pet food bowls clean and sealed in with their food when it is not meal time. The fridge (which we have not replaced yet) has been roach free completely (have been daily checking 4-6 times) the entire 2 weeks.

I'm so happy I live in a home now that I can walk on the floors with no hesitation! My previous apartment was so bad you couldn't go barefoot without stepping on the hundreds of babies that stormed the kitchen floors at night. :(

I will be reapplying bait as needed and plan to do a total re-baiting every 6 months or so. Again, thanks for all the wonderful help and comments from everyone :)

Idk how it is everywhere but here if you're renting and there's a roach infestation the landlord has to get rid of it or you can get the lease terminated. So to those people who are renting and feel stuck because of the lease check the laws in your area you may be able to end it.

I have recently purchased a place abroad. I work from home and plan to spend half my time there. During my last brief visit (I went to arrange for some building work to be done), I found quite a few dead cockroaches, and I have a total phobia. When coming back home and doing research from a safe distance, I realised that the black spots I had seen on floors, inside kitchen drawers etc. is roach poo and that the thing which looked a bit like a mouse dropping is an egg case. When I wipe up the black spots, new ones appear so I am pretty sure there must be quite heavy activity going on although I have not seen many live ones (1 half dead, and 2 babies in December). I feel quite optimistic after reading your "'ible" and have ordered 2 kinds of gel in addition to everything I need for your recipe. I go back in 2 days time and look forward to trying to sort everything out, although I am also dreading it.

My main worry is that I am having the whole place fully rewired, which means a few weeks of loads of new holes being made in the walls and so on. There will probably be a lot of dust. I'll try to keep it as clean as possible, but do you think the building work will interfere with the baiting? I'll follow the caulk/foam tips for pipes, around windows etc. where no work is being done. Once it is all done, I'll do the electricity sockets as suggested.

It is really good of you to be so responsive and helping so many people, good on you!

Ninzerbean (author)  karamba712 months ago
Dear Karamba,
If I answer your question may I come visit? It sounds great in that it is sure to not have any roaches. Anyway the new wiring is a GREAT time to stick the bait in the holes in the walls. This is really super news. Roaches don't care about dust and dirt, they are looking for food. Just make sure your workers are neat freaks in that they don't stick food remains inside walls - a common practice - out of sight out of mind. Soda drinks are almost normal to find inside walls. But all in all this is the perfect time to bait. Get that stuff into every hole and opening that is made during the rewiring. Enjoy your roach-free second home!

If this works, and I am hopeful, you will be more than welcome ;-) I have some commercial gel baits which I will use in places as well.

I got here late last night, and I am pleased to say I have found no more dead roaches and no more faeces. I am happy, but also don't quite believe it. I am still going to blitz (although with a bit less urgency than I thought) and bait the flat, but I think and hope it was less bad than I thought and that it should all work out in the end.


First I like to thank you for your information you provided. But there thing is I live in the UAE and I just moved into a new studio that have roaches every. Where. Mainly the kitchen, the toilet and pretty much anywhere. But here I don't think I'll find the exact same poison you're using to kill those unnecessary insects. Could you please tell me a substitute to use or maybe the anything with the same effect. I got the studio for a year and I know for a guy I shouldn't be afraid of those, but I have the biggest phobia. I almost got a heart attack once seeing a dead one upside down.
Ninzerbean (author)  George.A.Baskharon2 months ago
Is there a reason you can't order boric acid online in the UAE? There is no substitute that I know of that is as safe to use, but I guess any poison disguised in something delicious would have the same effect. But it would have to be really inert - have no smell or bad taste. Really, I just don't know.

Hi! Thank you for your well written instructable. i mixed flour, honey, boric acid powder as per your instructions two days ago. I baited my house as you suggested, especially around the kitchen area. I know it will take time to work but I have been seeing almost double/triple the amount of roaches in the past two nights after i placed the baits. I have been holding off on killing them on sight (one because they gross me out and two because I'm hoping they will eat the food and take it back to their lair.) I haven't seen them eat it (I put a few in cabinets in the corners so that I can check on the bait). Should I be worried that there the ratio isn't right? i mixed the flour/boric acid and added honey until it looked like peanut butter. I would greatly appreciate any advice! I've been poring over the comments but didn't find anyone saying that there was a big increase in roaches.

Ninzerbean (author)  aryali2 months ago

There have been comments about seeing more roaches after baiting, they do die down (puns are always intended) but it does mean that you have a nest somewhere inside that you must deal with first. Keep the vacuum out to use if you don't like killing the ones you are seeing. I know what you mean about grossing out. Normally seeing more is NOT the case but because it has been written about at least twice I think it is because you have not gotten rid of the infestation, so it will take longer. But that is only my guess. My infestation was beaten down by the professionals and then they used the bait to keep them away.

Your ratio is just fine btw. Just make sure you put it in ALL the places I suggest in step 7.

aryali Ninzerbean2 months ago

Thanks! I put them in all the places my dad and I could reach. They are german roaches and I saw that you suggested they might be harder to get rid of. I will let you know of any updates. Thanks for the reply. I checked behind the fridge, under the sink and in the cabinets but couldn't find the infestation. I'm not quite sure where else to look. If anyone has input please let me know.

Ninzerbean (author)  onlygod2 months ago
Try getting some foggers and leave them on when you go out for the day. That should do the trick for the short term. I would not use my bait because it takes a long time to do it right and you are on vacation!
alee132 months ago
I just found this post and I definitely want to try it! The thing is, I'm pretty sure there is a colony inside at the least the electronic part of my oven (it runs on gas but has electric for the settings and such). Any advice on specifically where to bait for this? I can probably move the oven away from the wall but can't really take it apart and I'm nervous about putting any bait inside. Not sure how it would react with the gas. The house is a rental and the oven belongs to the landlord.
Ninzerbean (author)  alee132 months ago
You will need to get rid of the colony first. For many reasons this is the best solution. I would suggest a strong vacuum. Or better yet ask for a new oven from the landlord.
alee13 Ninzerbean2 months ago
I doubt that they would provide a new oven for that reason... They'd say I brought the pests in. I can try a vacuum, I'm just not sure how to get to the inside of the electric panel

We moved into a house a few weeks ago and we are a bit out in the "sticks" and have noticed 1-2 roaches here and there but my husband was sure that they were waterbugs. I do not clean my drawers and insides of cabinets every week but I keep the surfaces and everything else as clean as I can. I am up at night very often and the other night i noticed a roach climbing up my drink. EW, i was able to kill it and look at it and determined it was a male german roach.( 2 black stripes and wings, ironic- because I grew up in germany) Today i started cleaning out all cabinets, behind the stove and the fridge. I found a roachfamily ( about 10) hiding in a cabinet we do not use at all, there is no moisture there either. I presented your Idea to my husband and hope we will try it out before getting an expert. I will definitely report back!

Ninzerbean (author)  SabrinaL22 months ago

There must be a link between your growing up in Germany and the... just kidding. Anyway have your husband read the comments, maybe a few hundred or so, ask him if he wants to see roaches at the end of each month or not at all. Exterminators do not stay in business if you don't have roaches. They have to make sure that the roaches only stay out of sight for 30 days so that you know that your money is doing something. So you will keep getting monthly pest control.

eltyshaun3 months ago
I hate roaches. The sight of them makes me go crazy. I recently broke up with my girlfriend and we are both neat freaks. So I had to get my own place asap. I found this place thst seemed nice. Was I in for a big surprise. I woke up in the middle of the night to get myself sonething to drink and they were everywhere. I also noticed there were different kinds big,small and tiny. I nearly lost my mind. Went to the store and bought all types of Tupperware to store dishes,utensils you name it. Whatever else that couldn't fit like my cups, store them in my refrigerator. I complained to the apt manager and he sent the exterminator out there twice. Yeah they killed a few but it seemed like more can to take each one they killed place. I even went to try to attack them on my own. I used thst roach combat blurt stuff that people were praising online, did nothing, still more came. I even put boric acid all over my house. Killed a couple but stil more came. I even watched a few evade walking into the boric acid powdered. Now I have intelligent roaches. Its getting so bad now I'm finding them getting into my bedroom which has never happened before. I'm afraid to wake up with a festation on my bed or even worst crawling on my face. I looked at some of these comments and sulfur acids is definitely a no no cause I'm afraid it might affect my tenants. Please someone give me advice that they know will work. I have 9 months on my lease and I'm high tailing it out of there if I cant get a grip on this situation. I wont even buy new furniture afraid they will get in it and start a colony. Guests, forget about it. Its an embarrassing and I dont want anyone thinking im a dirty person or they are scared to eat in my house. SOMEONE HELP ME PLEASE!!!!!!!!!!!!!!!!!!!
Ninzerbean (author)  eltyshaun3 months ago
Why are you asking for help before you have tried this? I understand how upset you are, I was that upset as well, that is why I wrote this 'ible. But you are going to have to use it before it works. It's like how hard it is to win the lottery if you don't buy a ticket. Be sure to read all 8 steps, read a few hundred of the comments, you will be fine very soon. Really.
I will try it, I also read a woman on here who is a stay at home mom tried it and she still was having the issue. I was beginning to think we both might be dealing with the same issue. I've spread boric acid roach enoz all over my apt snd it has failed. I'll try your method and can you tell me approximately how long it will take so I may contact you with the results?
Ninzerbean (author)  eltyshaun3 months ago

To determine how long it takes to see results you have to put your situation in the best possible light - look thoroughly inside for inside populations, look to see how to plug up any holes you have or spaces that roaches can come through, make sure you have almost no cardboard and your kitchen area is perfectly clean etc. The less you do all of these things the longer using my bait will take to work and viceversa. For the people I know personally, whose houses I have been in, it takes one day to see results. It can take about 4 hours to bait an average sized home. Using expandable foam and a vac and other prep can take a whole day. At the point I used it on both of my houses since I wrote the 'ible I saw results the next day. But the evidence of a severe problem at this, my second home, took a few weeks to be finally done with ever seeing a roach, alive. It was not until I redid the kitchen last year and was pulling the insulation out from between the studs that I saw that this house was a roach house for sure. It was very gross, but they were all dead. It had been over a year since I had baited.

Eltyshaun, this can be confusing information because I tend to write too much and everyone's situation is different, but depending on how big your problem is and how much prep work you do before baiting will determine how fast your roaches leave. Ideally it will be the next day.

Spreading boric acid powder around is the opposite of what I am trying to get you to do here, that will not keep roaches away, you won't do much good at keeping them away if you just kill some. You have to make your house a known death trap to the roaches, teach them not to come back. I urge you to re-read this comment, and the 'ible, and few hundred or so comments to get a grasp on what your problem is like compared to others and how hard you have to work. But once it's done it's done, your roaches won't come back for years and years.

Ok I'm going to purchase some foam sealant today and start the process. I'll keep you informed on the results. Wish me luck!!!!!

Ninzerbean (author)  eltyshaun3 months ago

Hey eltyshaun, give me an update, how's it going?

Hey Ninzerbean, first off I want to say thank you for your helpful information and for staying in contact. I did what you ask and for the first couple of days I saw a few take the bait and after consuming it, they would crawl away. Then a couple days later I would still see a couple around and a few always in my kitchen sink. I also saw some dead ones on the floor and in the corners. I started killing the ones I saw alive hoping I was helping the situation. Then a day later it got really cold outside and then I saw a couple. Now I see one or two every now and then and a couple days after that I've only seen one so far. Now for the past couple of days after that, I walk in the kitchen and I don't see any around like I use to, but I'm sure maybe one will come out or even 2 so I figure its still working its magic. I was right so now one or two would come out a couple to a few days later at a time especially the baby ones. So I'm still keeping an eye out because I have started the treatment on December 30 and it is now the 15th of January. I'm hoping by the end of this month, I wont see any more roaches. A new realty company has taken over my apartment complex and they have hired terminex and they want us to remove any baits or powders associated with killing roaches so that the stuff they use wont cause the roaches to go into hiding in the walls. I really don't want to do that because I feel that if I leave the bait that you recommended, in time it just might work and get rid of all the roaches. What's your thoughts on everything I just posted?

Ninzerbean (author)  eltyshaun3 months ago

Hi eltyshaun, thank you for keeping in touch. I will get to your question in a moment but first I have to ask how you can see roaches eating the bait - it should be in places that you can not see - behind drawers, inside the walls, around pipes under your sink, etc. Most roaches are doing their roach thing out of sight, the bait should be out of sight too. It really should not be possible for you to see them eat the bait.

But do not remove it when the Terminex (in my experience the worst of them all) people come, but make sure it is out of sight. Remember that the exterminators make money by getting rid of roaches for a month, then they come back. If the roaches did not come back the exterminators would go out of business. That is why they don't want you to use this bait. If you don't have roaches (and soon you won't) the exterminators will be out of a job.

The roaches ARE hiding in your walls - the stuff they use will cause the roaches to hid or die but only for a month. That is the dumbest thing I have ever heard. Does it make sense to you? You could be a jerk and ask for proof of what they are saying, but just make sure your bait is hidden - as it should be anyway - and let them do their thing, as long as you don't have to pay for it. I wouldn't let them in if it were me, but it probably won't hurt. I am just not into chemicals around my house.

Well to answer your question how I saw the roaches eating the bait, I put some bait above the windows frames and door frames and particularly on the window frame I saw 2 of them eating it. I told you, I had a pretty bad infestation since they were coming out during the day. Now since I last wrote you 4 days ago, I haven't seen any, even when I get up late night, early morning, I don't see one, not even a baby one. I can't thank you enough and I did think that was odd what the guy told me cause when I told the terminex guy I had bait everywhere he said good and didn't even spray any area. he most know something. Anyways, thanks again! I'm still gonna keep in eye out though just in case. If anything changes, Ill be right back on here hitting you up.

Dear Llilitu, To find out what kind of roaches you have, you will have to research them, maybe online. That is way beyond the help I am willing to give because it would mean I would have to look at photos of roaches. Ugh. Could you delete your other two comments that are repeated below as they are just duplicates.

Well i was in my kichen, cleaning and making sure food in shelves were sealed. Made the bait like you said except my house is only 1000 sq. Ft. The next morning saw one eat some of bait and run to hiding place. Now they just walk past thr bait. Going to do rest of house today. Does it lose its sme or something the longer it sits? Because they sure arent going for it.
Ninzerbean (author)  Pixiewings83 months ago

Pixiewings8 - you should not have the bait where you can see it. See step 7 for where to place it. They are walking past the bait on their way to a dark damp warm place, those are the places you want to place a bit of bait, but really you need to follow the instructions in step 7.

Hi. Thanks for the reply. I did put it where you said in step 7. In outlets, on pipes, behind drawers, behind stuff on shelves, under stove, etc. That was just extra places where I put it

You are so brave! Thanks so much for posting this, I'm going to have to gather my courage and get it done. Hopefully it works well on German roaches.

Ninzerbean (author)  TerminalxSound3 months ago

Germans are harder because they live inside - you will have to search out their inside-nests to get a handle on them because they breed so quickly that you have to knock them down before you will see dramatic results from my bait. Read lots and lots of comments - there is a of experience to learn from there. Good luck, be brave. Look at game players, microwave ovens, get rid of all of your cardboard. All the info is in the comments and the 'ible itself.

We have to move out of our home asap. Between work and having a child it was hard to find a place in the city so quickly. We have never had a roach problem but I have seen a friend who did and it was horrific. I have severe anxiety and I couldn't deal living how they had to with my child. We have luckily found an apartment that is available. The apartment is nice, other then not have central ac and heat. However, they said the previous tenant had bad roaches. They assured me that the apartment was bombed 3 times and cleaned and the fridge was taken out. They keep assuring me it's nothing to worry about and told me they would bomb again if need be but shouldn't have to. I don't have a lot of options but is this a mistake moving in? Sure re roaches are gone now but since this is an apartment will they be back shortly after signing our life away?? Please help!!!!
Ninzerbean (author)  Inneedofadvice1233 months ago
I think it is good that the management was upfront with you about the previous tenant. But roaches like inside the walls, in warm and wet places like behind the pipes going into the walls. Bombing and removing the fridge is not a 100% sure thing to be sure there are no more roaches you would have to look carefully for any feces, or egg cases. You would have to pull the oven away from the wall and look carefully inside of it. Does this place have carpet? I would look under that before you move in. If you have no choice then at the very least use my bait everywhere before you move in. I am just a bit suspicious - why did they bomb the apartment 3 times? 3? Why wasn't once enough. Maybe pay an exterminator a small fee to thoroughly inspect the apt?

This is great advice. I flip houses for a living. Most of the houses I buy are initially in bad condition and are usually with a roach problem. From my experience, I would say I've been pretty successful getting rid of roaches. I would like to add a few more tips to supplement.

- Boric Acid Method. Works great! The important thing is to make sure you put it throughout the WHOLE HOUSE. This includes attics, AC, water heater, and all those other places where applying becomes a challenge. Instead of open areas, apply around edges, behind stuff, nooks, and crannies. Should be somewhat labor intensive. Gotta do this for at least 2 weeks.

- Winterize. This is probably the most interesting trick I picked up. Roaches need water to live. They can live for weeks without food, but die much sooner without water. What I do is cut off the water supply at the main. Then, winterize the home. Winterizing is basically pouring an "anti-freeze"-type solution in your pipes so they don't freeze. Its safer than it sounds. Basically, roaches don't drink this water. No water equals no roaches. This will require you to live away from your homes for a while. Then de-winterize. Turn on all the faucets and let the pipes clear out for about an hour. Get a plumber to do this. I pay my plumber $50 for winterize/de-winterize services.

- Boric Acid Part 2. I usually do this last. Spread some boric acid in powder form around the perimeter of your home. Roaches don't usually eat the powder form but they'll stay clear of it. If they trespass, they they will get some on their bodies. This will be absorbed, or they'll lick it off. Either way, they'll die from it.

Hope this helps.

Ninzerbean (author)  oldyes3 months ago
Great info about winterizing for those that can do this. It's nice to know that you are selling roach-free homes.

I go into detail in step 7 about where to apply the bait but most people skip that step. Since it can take 4 hours to do an average home by yourself how do you do it for 2 weeks? After you bait the whole house what are you doing for the other 13 days of the 2 weeks you refer to?

Thank you for commenting.

Some of them are very difficult to eradicate because they will form multiple colonies all over the house in every little place they can get into. They ESPECIALLY like warm places with small entry points. This means inside appliances and other electrical equipment like cable tv boxes, audio equipment, computers, power adapters, chargers etc. The female will stay inside there laying egg sacs and the tiny young ones will come out and spread the infestation.

@ninzerbean - hello! We just moved into our first house, which is very old and saw NOTHING at all upon moving in - no signs of roaches whatsoever. Before we left for vacation, I noticed an "adult-sized" roach on the kitchen counter, killed it, and had a mini meltdown. Upon getting back from vacation, I noticed a small roach (like the size of half a hole punch) on the stove and then saw another the next day, also on the stove. I was having such a freak out that I pulled all appliances away from the wall - to see no signs of roaches behind them, just dust and some old toys, which I cleaned up. I also checked the cabinets and wiped them out again. We immediately baited following the steps you have provided. We did this about 3 or 4 days ago but we continue to see about 2-3 smallish (again like half the size of a hole punch) bugs. Does this method also work for these "babies" that seem to be coming from the oven? We've only seen two that were even close to being adult-sized (or so I think) - which I understand there could be MANY more, eeek. Along with everyone else, I am having major anxiety issues with this. Should I just continue to be patient and let the bait work its magic, or is there something else I should be doing? The only location we have ever seen any bugs at all is in the kitchen.

Ninzerbean (author)  nomobugs3 months ago
Firstly you must bait the WHOLE house, this will take a few hours. It doesn't matter that you are only seeing them in the kitchen, they are there for food but they live all over inside the walls. Be sure to view each photo, read all 8 steps. I think you have the regular ones and the little ones are babies that are hatching from egg cases. Yes, I understand you are freaking out. You have to get a grip and put this fear into perspective - there are far worse things so think of one of the more very worse things and dwell on that while you pull apart your stove.

I was happy to read that you pulled everything away from the wall to investigate but believe me they are somewhere. Think about what they like to be able to find them - warmth, wet, dark. Think about anything that you leave plugged in, if it is plugged in it gets warm. Roaches have no bones, they can flatten themselves into and under the tiniest places.

And yes, to your question, this bait will kill the babies you are seeing. Read the comment section, take a break and go investigate for any openings to the walls behind your dryer or washer, under the sinks where the pipes come in from outside, behind your dishwasher. Plumbers and builders do not care at all if the holes they make to install pipes are sealed. Really, they just don't care. Amazing eh?

Seeing an adult before you left on vacation worries me, if it was in the daytime especially. Anyway, stay in touch, let me know how it goes, especially if you find any anywhere unusual or if you didn't bait the whole house and it you find any holes that you can seal with expanding foam. That will make a HUGE difference. Just keep in touch, we can all learn from your experiences.

I don't think we will throw the eco-system out of balance if we rid the world of roaches.

Sevin Dust it dose MIRACLES!!! Solved my problems with in TWO DAYS!!! I had german roaches and many other roach species I had never seen before in my life RUNNING WILD!! In my new apartment I had major axiety. My god mom told me about Sevin Dust. Its a powder for out door use on gardens but my god mom has used it for years inside her home and it has never been an issue for her pets or kids and She did not mix it with anything she told me just pour the powder every were in corners and spread it out wearing gloves or a spoon but you can mix it if you want to be more discrete and dont want your guests seeing powder all over your place. I personally did not give a damn I perfer my guests to see powder then nasty roaches any day of the year! I poured the powder in the edges of each room in my apartment and spread it out with a spoon. I put it on counter top edges, inside cabinets, at the bottom of my windows and doors. I even went a step further and spread it on my patio and grass next to my apartment. The second day the roaches were gone!!! My god mom informed me it kills mice as well and its good to put the powder down every 4-8 months. I have researched the Boric Acid and its very popular as well but I did not find out about it till after using the Sevin Dust wich is now my new Best friend!!

Jasmne.Dai, Here is a link to the Material Safety Data Sheet on the poison you have put inside of your house - dangerous to you, pets, children, bees, plants, the water system, you name it and you have harmed it. I would suggest a respirator and lots of vacuuming to get rid of it. Or call in professionals, you are at risk. It is not a product to use inside, it is not a product to even touch with your hands, it is DANGEROUS and you should warn anyone who comes into your house until you can get rid of it. I'm sorry to tell you this but after you read the MSDS I think you will be as concerned for your health as I am.
Jiad Ninzerbean3 months ago
Thank you I do appreciate but again my GM and I have recently meet others that have used this for years as I stated before inside the home and has never had an issue and they are very healthy people and the animals and kids have never had a issue and mind you my GM Is now in her early 50's her 3 kids now in there twenties. She started the use 10 years ago. I meet her friend that actually got her hip to this and she has a hudge house and a big family along with pets and has never had a issue. She infomed me once she got it on her skin nothing happened. She simply washed it off. I think that warnings label over do it some time for the companies saftey they dont want to be sued lol but I feel if it were that bad the people who I know that have used it would have all been sick or some sort of issue by now. So to each its own if you dont feel its safe in your opinion its simple dont do it.
Ninzerbean (author)  Jiad3 months ago


I appreciate that you don't think there is any harm in the insecticide that is for outdoor use that you are using inside because no one you know has gotten sick. I appreciate that you are, like myself, trying to help people - but this is not the place to advocate a known poison such as Sevin dust when what I am trying to do here is give a nontoxic way to rid people of their roaches, a way that won't harm our eco-system, bees, dogs, cats, pets, children, a bait that can be applied as a paste so that it can be applied in places that animals and kids can't get to by mistake and even if they did it is not toxic. Your method posted here in the comment section, is only going to confuse people into thinking that I advocate Sevin dust. I don't - and this is why: from the MSDS: "Repeated overexposure may cause more severe cholinesterase inhibition with more pronounced symptoms. May lead to rapid onset of nausea, vomiting, diarrhea, abdominal pain, involuntary shaking, excess salivation, pinpoint pupils, blurred vision, profuse sweating, temporary paralysis, respiratory depression, and convulsions. Do not take internally. Inhalation Harmful if inhaled. May produce symptoms similar to those from ingestion. Avoid breathing dust. Chronic or Delayed Long-Term, This product or its components may have target organ effects. This product or its components may have long term (chronic) health effects."

Call me overly cautious, but why take a chance with a chemical such as Sevin powder, that if you get on your skin you need to wash for 15 minutes and call a poison control center? The common sense that you are advocating tells me to read the directions. MSDS's have saved the lives and quality of life for many people who otherwise would still be using toxic solvents in an unsafe way in schools and workplaces without otherwise knowing the long term effects of doing so.

For the long term health of everyone who comes into your house, eats food that your prepare or wonders why there are no bees outside, I can only urge you to get that poison out of your house.

I showed my GM and some friends your method and they liked it as well and found it to be A great ideai!!! Its just they are used to the Sevin Dust method.
Jiad Ninzerbean3 months ago
And also I forgot to add that MSDS sheet is no different than poisons I have read up on in the past that can be placed in the home to rid bugs, mice etc... Its common sense you dont go around putting things like this inside your mouth or sniffing it up your nose. Thats asking for trouble. Now another product I used in the past that is really good BUT caused my eyes to burn and turn red was Raid spray and When I use bleach it dose the same thing. I actually had to open windows. Its alot of things that can harm you. That every day people use on the regular and again its just common sense. Im not going to be sniffing in Raid or bleach up my nose eithor.
Hello. Thank you so much for posting this and checking up on it. I used this recipe about a week ago. I have it all over my house. Ever since I did it, it has been so much worse though. I see them everywhere. Before it was just in my kitchen. Now I am seeing them all over my house. It is literally causing me so much anxiety. I am pregnant with two toddlers which doesn't help. I have read the whole post multiple times, so I'm pretty sure I did it right. Is it normal for them to all come out after doing it? Is there anything else I can do? We will be buying a house next year and more then anything I don't want to bring them over. We will be leaving all the kitchen appliances. Thank you so much for your time.
Ninzerbean (author)  melissa.burnham33 months ago
Dear Melissa.burnham3,
This is not normal - the only thing I can think is that there may have been a huge colony living inside your house that you did not know about, you may be dealing with German roaches which live inside. I had the giant ones also called palmettos, they live outside but come inside to get food. But anyway I think the thing to do here is try another form of pest killer that is safe to be around for you and the kids, to get rid of them. I think that the reason you are seeing so many after baiting is because they are freaking out about having nothing to eat but that poison. They are swarming to find new food, they know there is a big problem now. I believe you did everything in the post correctly - the difference may be in that you had a infestation inside and or they were Germans. This will still work, but you are just going to have to be more diligent. Because you are pregnant the thing I would do personally is vacuum and spray with hairspray if you have to. But this is not normal, I don't know for sure but I think I have read about this happening two other times.
Keep me posted. I really wish there was more I could do. But your experience will help others, that is why I want you to stay in touch.
Oh no... They are the German ones. Maybe I need to bomb, but if its a colony inside walls I doubt it would get to them. I vacuum and clean non stop it feels like. I'm a stay at home mom with two toddlers. I see them everywhere all day long. I didn't use to see more then a couple and only in the kitchen. I just don't know what to do.
I have posted photos as well
Hi not sure if you have resolved your problem. try Sevin Dust it dose MIRACLES!!! Solved my problems with in TWO DAYS!!! I had german roaches and many other roach species I had never seen before in my life RUNNING WILD!! In my new apartment I had major axiety. My god mom told me about Sevin Dust. Its a powder for out door use on gardens but my god mom has used it for years inside her home and it has never been an issue for her pets or kids and She did not mix it with anything she told me just pour the powder every were in corners and spread it out with your hand wearing gloves or a spoon but you can mix it if you want to be more discrete and dont want your guests seeing powder all over your place.

I put it on counter top edges, inside cabinets, at the bottom of my windows and doors. I even went a step further and spread it on my patio and grass next to my apartment. The second day the roaches were gone!!! I could not beleive it!!! My god mom informed me it kills mice too!! And that its good to put the powder down every 4 to 8 months or when you start seeing bugs again. Now I have done my research on the Boric Acid and its very popular alot of people are using it but insense that made your situation worse I think you should try the Sevin Dust like I did and I hope it works for you as well:)

I know a way you can get rid of all of them in one go, but it is somewhat dangerous (so disclaimer, use this advice at your own risk) if you don't know what you are doing, but it is worth it. I moved into a place with an ex girlfriend that was infested with them. A friend told me a trick. I went to a garden supply store and bought a bag of sulfur, I put the bag of sulfur in a pot that I wasn't going to use ever again, put a little water in the pot, sat it on the stove on low, and we left the place for a few hours. The sulfur burning will leak into any crack or crevice in the home and anything that breaths that remains inside will die which includes roaches. If you decide to do this, you will need to be extra careful. Once you do it you will need to let the home air out. Open the front and back doors and sit in your car until it airs out enough for you to enter the home. Then you can go inside, open windows, set your alarm, and maybe spend the night at a relatives. I know it seems like a lot, but trust me, it was worth it. In Russia they use this method and it not only kills all roaches but repels them for up to 10 years, they hate the smell. People used to use sulfur candles, but they have since been made illegal in some places.

Ninzerbean (author)  thebestthereis3 months ago

Dear thebestthereis,

It's comments like yours that make the comment section of Instructables as useful as the 'ibles themselves. Thank you so much for sharing your method which I have no doubt works. I doubt that people have the nerves of steel and fortitude that you have - I mean living with your ex-girlfriend must have been as crazy as the roach problem ;)

More and more often I am receiving comments about what must be German roaches (which live in colonies inside) and this is just great advice to point people towards - combined with my bait, the roaches should be gone in one day - and never come back. I can't actually advocate your method because I have never used the sulphur stuff and I would really worry if I were in an apartment building and it got into the neighbors' apartments and what might ensue, but I thank you very much for your time in sharing what worked for you, your brother and your ex-girlfriend. When are you going to get your own place? :)

I keep telling people that if they have a colony living inside they must eradicate that first, and it usually is the kitchen applicances and game players and audio equipment: warm and dry. Buying used kitchen appliances, ariconditioners or game players is just asking for trouble these days.

@ninzerbean, well it was a place me and my girlfriend at the time had gotten together on equal footing. I let her pick the location which turned out to be a colossal mistake because I was new to the city and didn't know the area too much. As for when I was living with my older brother, that was during my final year in high school a couple of yrs ago when I was 18. Yes I have since gotten my own place. :) But back to the matter at hand here, yes the sulfur method can be extremely dangerous as you've stated, and in an apartment building I probably wouldn't try it, only as a last resort. I initially heard of the sulfur method from my grandmother. Her friend in New York had roaches and the maintenance people weren't doing much about it so she took the measure to put half a pot of sulfur on the stove and go downtown for a couple of hours. It worked, got rid of all the roaches in the building, but the tenants had to go out of the building for hours. It creates sulfur dioxide if I am not mistaken, which inhaled directly for long periods is very deadly, which again is why I would only use this method in a house where no one else was at risk. But your method and my method are very similar. The key is to Bait, Trap, Kill. Lure the roaches and poison them. It takes longer than sulfur, but it is effective. Bombs arent

Also, if you do not want to use the sulfur method which is a definite way to get rid of them all, you can do what I did when I lived at my brother's house. He had a bad infestation that came from some very nasty neighbors. It was so bad the roaches got inside the microwave, you could see them behind the timer. What I did there because I hadn't known about the sulfur was to buy four cans of raid, paper plates, boric acid, two bottles of bleach, a couple of jars and I took an empty spray bottle and mixed the bleach with dish soap and put it in the bottle. I pulled all of the dishes from the cabinets, and put them in the sink, and I hosed the cabinets down with raid (I used different kinds of raid because roaches develop an immunity if you use the same exact product over and over again). Any roach I saw I sprayed directly on contact. I washed all dishes and put them in the dishwasher. I pulled the refrigerator and stove from up against the wall to find a nest back there. I raided them, killing everyone I saw, and then I sprayed the bleach and soap mix all over the walls. Roaches leave brown streaks on the walls, these are their feces, and they can smell each other and this is how they follow the trails. I made sure I bleached and scrubbed all of the brown feces trails off the walls, and out of the cabinets. Then I took peanut butter, and sugar, and mixed boric acid with it, and put it on paper plates, and slid them under the stove and under the refrigerator because roaches love dark places. I took the jars I got and put water in them and put them in corners that were out of sight or range of my brother's dog (roaches will go in the jars to get the water if you place it in a corner, and for some reason once they get in they cant get out and they drown), then (I wouldn't suggest this because it can be dangerous) I sprayed raid in the outlets (roaches hide their often because of the dark). Instead of this, I would suggest getting those plugins they have that you plug in the outlet that repels them......

After doing all of this the roach population was drastically cut. I counted them as I killed them, and the ones that came out of my brother's microwave alone were over 50 roaches. As I was raiding them they wouldn't come out, so I kept turning the microwave on at 10 minute intervals to get it so hot that the heat would run them out, then I would spray them directly with raid. After all of this, the roaches were gone. Make sure you raid regularly at intervals, keep your house clean, and also use Home Defense. Switch up your products before the roaches can develop immunity to them. THIS is key. Exterminators know this, but they continually use the exact same stuff.

Does anyone know if it gets way worse before getting better?! I am going crazy.

Thanks for sharing this knowledge. By the sheer number of views this has, you know you're doing something right! I've personally never had roach problems (just a critter or two here and there) but coming across this allows me to store it in that special part of my memory where if its ever a problem I'll know right where to read. Yay for knowledge!

What kind of roaches does this kill i seen u put a comment on someones comment that said u might be dealing with german roaches. So does it work for german roaches
Ninzerbean (author)  tiffany.yocum3 months ago
It does but it takes more effort - you have to get rid of the colony inside your house - it can be in appliances or audio equipment. You have to be really diligent in getting rid of all cardboard and cleaning cleaning cleaning. It is just simply harder to get rid of Germans.

Ninzerbean (author)  Cne343 months ago
I don't know. You have to read the ingredients and see how high the percentage of boric acid is.
DavidB333 months ago

5 lbs Boric Acid + free shipping. Arrives by US mail. Powder boric acid is very fine, can be dusty to work with but is essential for use in dry pest control applications. $15.95. Do the math. I used a baby powder container to poof it and peanut butter, corn syurp, DME, and boric acid with a dash of cinnamon for my baits. Share with friends.

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!

Ninzerbean (author)  KarenZ14 months ago
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)  coll28504 months 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 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)  charko4 months 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)  charko4 months 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.

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)  mlbishop604 months 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 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)  bonloveslife4 months 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.

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

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.

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)  mizzdawn4 months 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)  Ymv134 months 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)  VeraA14 months 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)  zymirmommy4 months ago
Caulk would do the trick to seal up those gaps.

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)  ezzyscofield4 months 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

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)  80sbaby4ever5 months 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.34 months 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?

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...

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.7985 months 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)  CaseyJaye5 months 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.
TaraT25 months ago

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

Ninzerbean (author)  TaraT25 months 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.
CaseyJaye TaraT25 months ago

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.

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)  cwhitty135 months 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.

Ninzerbean (author)  VickiD15 months ago
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.
cwhitty135 months ago
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.
Ninzerbean (author)  maryellenlopez5 months ago
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.rueda5 months 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.rueda5 months 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.rueda5 months 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.rueda5 months 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.7125 months 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) months 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.

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)  nomore845 months 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)  Bootssie5 months 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 :'(
Ninzerbean (author)  courtney.r.525 months ago
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?

Ninzerbean (author)  dawn.otto.945 months ago
I'm sorry that I cannot help you, it sounds pretty bad. All I can so is suggest that your parents read this 'ible and see that they can so something about the problem that really costs so little. I am sorry I can't do more.

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!
Ninzerbean (author)  Ssanders275 months ago
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)  JamesJ85 months 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)  MsMakish5 months 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.....

There is no reason to ever clean or remove it, it's out of sight doing it's thing, no need to ever remove it.
Where can i buy the boric acid i was told to use borax i tried it kill a few but i didnt see any improvement i want to try ur receipt asap
Ninzerbean (author)  angelito.hermoso.925 months ago
Borax is not Boric Acid, it will not work. I just did a google search for Boric Acid and got tons of hits, Amazon, Wal-Mart, True Value, I don't think there are any shortages of where to find it. Good luck.
Allodynia5 months ago

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.

Ninzerbean (author)  Allodynia5 months ago
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.
suzysmith5 months ago

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)  suzysmith5 months 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.

You will have to read the back to see how much of it is boric acid. The stuff I used was 99% boric acid. Use your best judgement.
Katmom5 months 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)  Katmom5 months 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?

Will Borax work? Having a hard time finding Boric Acid..

Jordan I found Boric Acid At Co-Op today. It is on the Table with all the ingredients waiting for you to take action. Your pro-active I love it. -Your Dad. Ninzerbean Thank you for Answering Jordans question I've been buying Borax... lol, I guess we can get a lot of whites whiter... Single Father.

Ninzerbean (author)  JordanEaves_05 months ago
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.

Ninzerbean (author)  JordanEaves_05 months ago

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.

Carlos4495x35 months ago
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!!!
Ninzerbean (author)  Carlos4495x35 months ago
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 housewives6 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.
Ninzerbean (author)  desperate housewives5 months ago

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)  Andreacatanese085 months 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)  maryellenlopez5 months 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!

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)  wenderful6 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_06 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_06 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
rduarte126 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)  VIvanova876 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)  VIvanova876 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.

Mrsjo6 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 Mrsjo6 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)  Mrsjo6 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!

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

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.

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)  Ldivasmom6 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.

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_06 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)  KawaiiSugoiChanel6 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)  KawaiiSugoiChanel6 months ago

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

I know how you feel :( I hate those things so much.

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!!

Ninzerbean (author)  FoxysMyGirl9 months ago
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.1046 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
JessicaM66 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)  JessicaM66 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)  Branderdini6 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.reddekopp6 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.7986 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.126 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.

Ninzerbean (author)  Jonettemardavid6 months ago
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)  Amandalynlewis21796 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.yeager7 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!

Ninzerbean (author)  gina.camarata7 months ago
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)  WelcomeToGlitterville6 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)  katreceswenson7 months ago

I don't understand your question, sorry.

dcarma Ninzerbean7 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)  dcarma7 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.187 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.

wpickering27 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)  wpickering27 months ago
If it ain't broke, don't fix it. This works, there is just no reason to add Cypermethrin.
gina.camarata7 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)  Jonettemardavid7 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)  LindaF17 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)  LindaF17 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.

my shoe works better than all these methods.

I admire your tenacity, aaryak. You must know something I don't! I have tried your method with no success whatsoever.

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)  Jonettemardavid8 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.

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)  wireman3327 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.
boni147 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)  boni147 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.
shyatt21 year 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 shyatt27 months ago

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

Ninzerbean (author)  shyatt21 year 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)  reikimaster555511 months ago

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

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 Ivriniel7 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)  Omarsibles8 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.

Hi I follow your step that you has. So far I got it from store. Here what I have.

Hot Shot MaxAttrax Roach Killing Powder with Boric Acid

Normal flour.

Pancake syrup.

I did mixing them. Then my mom start complain because that way I made that for follow your step, it start to dry like rock. I told my mom I just follow the step. So I need to know if I did right thing. I just follow your step, that all.

cdavis388 months ago

After getting rid of them 10 years ago,I cried when I saw one the other day.I'm trying this,because I became so sensitive to chemicals the first time that I don't know if I could handle the exterminators again. I will post again after using it for a month to see how it does.Thank You.

therese8710 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)  therese879 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)  therese879 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)  therese8710 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.
FancyCheese9 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?

Ninzerbean (author)  FancyCheese9 months ago
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 !!

Ninzerbean (author)  FancyCheese9 months ago

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.

ElvenChild10 months ago

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)  ElvenChild10 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.

chennaiman10 months ago

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.

gracefam7211 months ago

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)  gracefam7211 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.
acline21 year ago
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)  acline212 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.

acline2 Ninzerbean11 months ago
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)  acline211 months ago

Great news and a great tip - thank you!

acline21 year 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.
boneyabba1 year 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?

chennaiman1 year 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)  chennaiman1 year 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.
