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

Step 1: What you will need

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

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

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

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

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

I did this last summer. It worked GREAT!!! Last night I saw the biggest roach ever outside my bedroom door. Do I really have to do it every year? Does the Boric Acid expire? I read somewhere it doesn't expire if it stays dry. Maybe it would make sense to put dry Boric next to the mixture?
Ninzerbean (author) in reply to Cindy TobinJun 12, 2013. 1:39 PM
I don't think you need to do this every year, maybe every two or three years. Is it possible you didn't do a really thorough job when you did it? Putting boric acid powder down will kill the roaches who run through it - but they won't bring it back to the colony and and learn not to go to your house. It's like bees. They communicate to each other.

There are hundreds of comments here - maybe you can glean some insight from reading them. Maybe a new colony moved into the neighborhood and they don't know about your house yet, but they will.

It never hurts to mix up another batch and put in places you might have missed the first time around. I know how scary that must have been to see that roach, I hope it won't happen again.

Hello, thanks for your reply, we did bait our townhome 1400 sqft of it. Since we baited almost 2wks ago we have not seen any dead or live roaches in our kitchen or dishwasher or next to our refrigerator. It is like they all just disappeared. My hubby and I think it's crazy, either your roach mix works magic or they got the hint and decided to go next door. I'm hoping they ate the bait and it killed the colony. Still haven't talked with the neighbors yet, but want to as soon as I get the courage. Just in case they "return". Anyways, thanks for your roach concoction and maybe the pest control company as well, and our persistance.

What ever worked or the combination of the three, I'm just glad it did. Thanks for writing.

I just moved from a roach infested apartment. And I mean it was infested! The last month or so I had seen around the freezer door and two even made their way into the fridge! I don't know if it was us or the neighbors we stayed there over a year roach free until the the past year. I threw away the microwave, George Foreman Grill , toaster, couch, reclining chair, entertainment center, VCR and my nice wooden dinner table. All of these items had roaches either in them. I just moved last Saturday and so far I have seen about 10 in the new place. I bought 2 bottles of 100% boric acid ( Zap A Roach brand) and sprinkled around some of the base boards- no all because I ran out. I NEED to get rid of these pests. Would peanut butter mixed with boric acid and sugar be a good bait. I have have 3 Hot Shot bombs I plan on doing tonight. Any suggestions you can bring would be helpful! Thanks!
Ninzerbean (author) in reply to jaipeaJun 6, 2013. 6:15 PM
You can give it a try - anything that will get the roaches to eat the boric acid it good. I have never tried peanut butter. Let us know if it works. Good luck.

It won't let me Reply to your comment.

Thank you for your reply. We bombed and fogged Friday night, the bombs we sat off were Bengal bombs enough for almost triple the amount of sq footage of the home. We left the attic way open and all the cabinets/fridge too. We also went a head and took off the covers and light switches to help it get in there good too.

Saturday we went and made the goo. We put it everywhere really thick... behind drawers, on door frames, in closets, behind light switches and covers, in cabinets and on the outside door frames too... with what was left he put it in the attic and left the container up there. Then we put the expandable foam around all the gaps that we could find... we moved the dish washer and put it there too.

Since then there have been a few big live ones in the kitchen and in one bedroom (which there never was one in the bedroom before).. However, there have been a lot of baby ones (smaller than ants) in the window sill in the living room. When our tenant went to kill them, some went outside through a tiny crack in the windowsill.. On closer inspection she says the babies are on the siding on the house.

Is this a good thing? How do we treat the outside of the home? My husband is going over later to caulk up the crack. I think we are all so stressed out about these things.

But with not seeing many big ones in the house that is a good sign right? How long til we should not see babies anymore? How do we treat the outside of the house?
Thank you for all your help :)
Ninzerbean (author) in reply to jmcalder3Jun 4, 2013. 12:04 PM
I was thinking of you guys this morning so I'm glad you wrote. I used to put bait around the house, anywhere I could stick it outside. This was usually because I mixed up so much I just wanted to use it all up.

I feel like the roach lady, I wish I knew more to be able to answer your questions with definitive answers, but all I know is from my own research and experience and other folks's comments. I think you have done everything there is to do. I'm proud and impressed. Anytime I hear about roaches after a treatment is because the people didn't do the whole house, like they didn't do a basement or a bedroom. But everyone who has been as thorough as you have has had success. I don't see why you won't. But since you are worried I am worried. I am the designated worrier in my family. So don't you worry, I'll worry for you.

As far as babies go, the egg cases you may have missed will still be able to hatch, but those babies won't be around more than a day before they eat some bait. Really, I actually don't think I even need to worry for you, you are going to be fine - and roach free. Really.

Write to me in a week and tell me you are not stressed any longer. This kind of thing sort of just sours everything in your life until you have it fixed, I understand.
jmcalder3 says: May 30, 2013. 7:09 PM
Thank you so much for such a quick reply. I talked to the girl who rents from us, and she thinks we are dealing with german cockroaches.. will this bait work well for them? She is the one who introduced me to this page (so glad!) and she thought she had read where they weren't attracted to the sweetness of your bait. I am going to go back and re-read the comments and take notes as you suggested. But I think we are dealing with german cockroaches and probably other kinds as well, she thought she has saw a few different kinds.

I went to the local hardware store today and bought Bengal bombs (I heard their the best), Bengal Gold Spray and the Roach Prufe that you had bought. The man there told me to bomb the place this weekend and then do it again next weekend. I told him that we were making this paste that you had talked about on here and he said yes that will bait them... but he said the bombs will not hurt the bait. But I am really afraid that they will, and if we do all this work I would hate to have to do it again next weekend.

So I am so confused!

She has removed all the cardboard from the house, and is keeping food in sealed containers. There are pretty close neighbors, but their not attached to the house. The house has a crawl space/attic that I think we should treat also.

I have never dealt with roaches before and after we get these taken care of, I hope I never have to again!
Ninzerbean (author) in reply to jmcalder3May 31, 2013. 3:35 AM
It's going to be fine, don't be confused over the opinions of bombing first or baiting. Just bomb, then bait. It's only my opinion but based on how many bugs you are going to kill in the bombing and how many egg cases they have on them, when you go to bait you will be at the very least dealing with less creepiness and it will be cleaner because you will have vacuumed up the dead guys. It's important to bait because of the colony thing - you want your bait to leave the house to go back to the colony so they can learn that your house is a threat to them. Think about how smart bees are - how they can tell each other where there is good food, where there is a new place to bring the hive to, it goes on and on. I think roaches are the same in that they live in a colony and they do communicate with each other in a simular way that bees do. This is my opinion only, I am NOT about to study roaches any more than I have already. But it makes sense.

Anyway, the german ones will die, don't worry, there are just more of them so it takes longer. You are going to be fine, your hard work will pay off, you will forget this whole experience one day, you are getting really sleepy. *snaps fingers* OK, wake up and go bomb and bait. Get the bait up in that attic/crawl space. Keep me posted. I care, we all learn from each other here.

Hi, I am hoping to try your method on my rental house this weekend. We have started having a problem there (noticeably) 4 weeks ago. Mostly in the kitchen (inside and behind the dish washer and fridge mostly) and a few in the bathroom and other places. We have bombed, sprayed, put out baits, boric acid and moth balls. We have not had much luck in getting rid of them. But we are going to take the day on Saturday to put your pastey mixture everywhere. Also we are going to get the foam caulk to do the places like you suggest.

My question is, do we put out your mixture first and then wait to see if it takes care of the problem or do we also bomb/spray.. or do we bomb/spray first then put out the paste.

The live ones that we see (if there are any after this) do we kill or let them take this bait back to their "friends"?

I am REALLY hoping that this works, I will update after this weekend.Sorry to ask so m any questions, I just don't want the paste and bombs/spray to cancel each other out.

Ninzerbean (author) in reply to jmcalder3May 30, 2013. 10:41 AM
This is a good question and one that you can only answer by evaluating how bad your infestation is. Personally I think I would bomb, then bait - reason being that I think it will be faster. Killing roaches is all well and good but getting them to tell their friends not to go to your house is better. So think this through.

Sealing up acces with the foam is really good. Getting rid of all cardboard is really really good. taking the time to get the bait into the walls using any access you have is really important. The dishwasher is something that if at all possible should be pulled out and the hoses that attach to the water checked to see if large gaps were left after the plumber set up that area for the dishwasher to be installed. Use the foam to seal those gaps.

As I know you have read, it takes a great deal of time to do this correctly - but you only have to spend that time once in 2 years or so. It's hard work, have your vacuum running near you incase you see egg cases, roach poop, dead roaches etc, then dispose of the bag or whatever your vac uses.

There are over 300 comments on here, there is some very helpful advice - and it's pretty entertaining reading, I would sit down and read and takes notes as you do so.

You won't see any live roaches after you bait. On the off chance you do kill them of course. I would bomb first for sure, I don't want to take a chance that you actually poison the bait so that they won't eat it.

Keep me posted on your progress, it will work, you just need to be super thorough. I say this because you have already done quite a lot and it has not worked - oh, don't use mothballs, those are toxic for you to breath and they won't bother roaches.

Remember to pull out your drawers to put the bait behind them - think to yourself that dark, damp, and up high places are where they like to go - so that is where you bait. And I can't say this enough - get rid of any cardboard. Put your pasta in freezer gallon bags, your flour in the freezer, your cracker boxes in the garbage and put everything that comes in cardboard in big ziplocks. The freezer kind I like the best because the plastic is thicker.

Hello I am wanting to know how we get rid of any roaches/nests etc that are in electronics or appliances? Your help would be greatly appreciated!
Ninzerbean (author) in reply to crj1024May 30, 2013. 4:16 AM
If you read through the comments you will find a good one on a PS3 player and I think something else, anyway bag the component up in a black garbage bag with bait - just putting the power alone will not work - I had the same experience with a wall unit AC. I finally gave up after 7 hours of work over the course of a week because the colony was so intrenched, but I was not able to take the 65 pound unit to the car wash and use their powerful vacuum, also I could not take the whole unit apart. This will be hard but taking the unit as much apart as you can after bagging for a week with bait will help. I'm sorry that I fear this is going to be a hard one unless you can disassemble as much as possible. Keep me posted though. Everyone can learn from what you do.
casadebug says: May 27, 2013. 9:02 AM
We have been battling german roaches for almost 2 mos. all in all about 20 roaches we have spotted. but who knows how many more are hiding in the walls. the first sight was by the dishwasher in kitchen, saw 2 and immediately called an exterminator. they came baited, put traps and dusted with something called maxforce. after that we did not see any for a couple of weeks. then spotted small baby ones again by dishwasher so my husband pulled dishwasher out and found 2 casings or egg capsules. we were beside ourselves! called exterminator again and came out to do same thing. they suspect it might be coming from neighbors? since they are mainly near dishwasher and sink or occasionally under sink.

after a week went by husband found one upstairs in the sink on his toothbrush yuck! and then following day found a HUGE one by the refrigerator that got stuck on one of the traps. it looked like it had a egg sack stuck to it's butt. my husband walked 2 blocks away from our home and killed it! didn't know what to do with it?

anyways we are done with these roaches and want them to go away completely.
how do we ask our neighbors, hey do you have roaches?
what else can we do besides what is already being done? an suggestions would be appreciated, please help us!
Ninzerbean (author) in reply to casadebugMay 28, 2013. 4:59 AM
Well first off killing them won't work - that is why the pest control companies stay in business, if you did not see dead one's you would think it was not working. The thing is that you have to use my bait so that they bring it back to the colony and kill them there and then the leftovers will spread the word that your place is not the place to go to - they don't want to die, they have skills, they won't go back.

Now on the other hand your neighbors are easy - you haver roaches so they have roaches, maybe from your place - but together you sit down and read the 'ible and follow it. Anything more I would write here is just repetition, read the comments too there is a ton to learn there aslo.

People who are not even slobs or even dirty pigs have roaches, it seems like an insult but it's not about you, it's about the colony, how it works, what was in your place before, neighbors yes, but it's more about controlling them before they control you. The roaches, not the neighbors.

Don't worry (I always say this but it is true), you are going to be alright, you will not have roaches, it takes time to do a good baiting, you can do it, you will get rid of them, be vigilant with that vacuum. NO NO NO cardboard in the house.
edwardsb421 says: May 6, 2013. 9:39 PM
Thanks for the reply. I only added a tiny bit of water and it was to help get the mixture mixed! I was having trouble with it turning into the consistency of peanut butter. Instead it was just like a ball of dough, so I added maybe a teaspoon of water. I did whip up another batch of it and this time was able to get everything to stir up into the consistency I was originally looking for! It just required a little more syrup than I put in it before. I just moved into a new home and was greeted by these nasty little buggers! I have sprayed, fogged and put out the Combat gel bait. I was still seeing some though, so I knew I had to try something else. I sure hope this does the trick! I'm hoping it does as I don't think that it was a bad infestation.. ...but then again, ONE roach is ONE too many for me! Anyway, I will let you know if it works! You've definitely helped many (by what the comments say) so here's to hoping for the best! :) .thanks again!
(And for some reason I couldn't reply to your comment to me..so had to leave a comment this way)
Ninzerbean (author) in reply to edwardsb421May 7, 2013. 3:45 AM
I'm glad you mixed up a new batch. It's not an exact science except not to add water, just more syrup until you get the right spreadable consistency, as you have found. But you don't have to hope it works - it will work. My mom sort of collects stuff and her house is sort of impossible to clean really well because there is so much stuff - in boxes made of cardboard no less, anyway I have stayed with her 4 times in the last year, once for a month, and there has not been one roach! She baited when I first wrote this 'ible and has not had to bait since - that's about 3 years now...maybe more. It works.
edwardsb421 says: May 6, 2013. 9:37 AM
Hi Ninzerbean! I came across your 'ible and wanted to ask a couple of questions!
I made up some of your "goo of doom", but since I didn't need as much as you made, I mixed 5-6 HEAPING tablespoons of boric acid, 1 1/2 tablespoons of flour, 2-3 tablespoons pancake syrup and some water.. Do you think this should this have enough boric acid in it to kill roaches?
Also, once I mixed everything together I did get a consistency of creamy peanut butter, but once I placed the bait out and went back to check a few hours later, it was like putty. Not rock HARD, but not peanut butter either. Is this the way it's supposed to do?
Thank you very much! I really hope this concoction kills these nasty little pests. I love my new home and really don't want a reason to despise it!
Ninzerbean (author) in reply to edwardsb421May 6, 2013. 9:45 AM
You should not have added water - that makes it get really hard. I think you used enough boric acid but not knowing the size of your home I really can't say if it was enough. You have to get bait on all of the places that the 'ible tells you to.

I have no idea if the roaches will still be attracted to the bait when it is that hard, I don't see why not but then again I really don't know. I personally would not take any chances and would do it again without water. It's your call though, keep me posted.
bcutnbords78 says: Apr 23, 2013. 1:11 AM
I just recently rented a house the has roaches. fogged twice still horrible... But after reading this I will be making the goo.. But I was thinking of an idea.. I used to have a lizard and I bred blatipica dubias.. to feed my lizard.. And in order to keep water for them I used the water crystals the would swell up when the hit water.. This was a way for the roaches to get water without drowning.. So I think I am gonna make you goo. Plus mix some of the powder in with water and poor it over the crystals.. and put them in the frigerators drain pan and in a container under sink stove and where ever else I can add it next to the goo, So that they have food and water... just a thought..

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

A side note for everyone. I did not have the attic sprayed with residual spray so will be baiting the attic; all outbuildings; and the cars. In fact, I might continue to just bait "surrounding my house" entirely also. I am on my very first week of no dead german roaches at all and it has been exactly 2 and one half months so I am pretty sure the bait is what did the trick (as well as my new love of caulk). We did not spray until a couple of weeks after we baited with the magic goo of doom. I forgot to mention that part. Now to bait the air conditioner and furnace etc.
Ninzerbean (author) in reply to cammyliciousMar 4, 2013. 11:05 AM
Wow, impressive - you ought to write an ible on it! Thank you ever so much for all of your sharing, I'm pretty happy for you - and your love of caulk which made me laugh out loud.
cammylicious says: Feb 21, 2013. 10:11 AM
We moved into a very, very old cottage in the Bahamas. We had to do the cleaning of the house and furniture when we moved in and guess what - roaches - American giant ones, german (baby and adults) everywhere - they seem shocked we were there. After a nervous breakdown, an exterminator came after a week of terror but it really did not do the trick. I found this instructable and this is what I did:

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

Some questions for the Board.

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

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

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

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

The Instructable was great and after arguing with my husband about the power of bait, I truly think that the spray helped the initial barrage but that the bait helped weed out the massive problem. I sure hope it lasts two years because baiting does take forever.
Ninzerbean (author) in reply to cammyliciousFeb 24, 2013. 10:46 AM
Wow, thank you for such detail on what you did, I am sure it will help others. The thing with the bait vs the spray is that the roaches live in colonies, huge colonies, and they need to take that bait back to their colony to feed roaches who are hanging out there, pretty soon they all know not to go to your house. If you kill them with spray they can't warn the others to stay away. Of course my bait kills the greedy ones who eat it at your house before they bring it back to the colony so you are going to see those dead ones. What you want to happen though if for the word to get out that your place and the apartment next to you are dead zones they must not go to. That was really smart of you to do the apartment while it is empty. The cars would certainly contain roaches, there are all sorts of yummy things to eat in old cars and it's dry there too. They need water but like to hang out in dry places. I think you are doing everything that can possible be done. I think you are safe to put your clothes in the drawers, there is no reason for them to go in the drawers anyway. Compared to how things were when you moved in I think your problem is basically over. German roaches are very hard to get rid of, harder than regular palmetto roaches. But please do the cabinets that the bug guy did, I swear what ever they use is not effective, they would go out of business if it was.

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

You could bait the cars too you know...

My kitchen is all ripped out and a new kitchen is going in, while the insulation and drywall are gone I am going to do a bang up job of putting bait on all the wood walls and studs. You would not believe how many dead roaches I found when we ripped the drywall off. The people before me (I'm in a new house from the one I did the 'ible in) had used a system where there were small tubes that ran all around the house put in when when it was built, periodically the exterminators would spray some poison into the terminals on the outside of the house. The result was that the house was infested when I moved in. But 10 months later, the contractor and I did not find one live roach in all the de-construction we did.

Yes, cats won't eat it. Just don't put the powder around like some people are doing, use the bait, put it in the places I suggest. My dogs and cats were not interested.

(For some reason it won't let me reply to the messages specifically)

OK... we are on day 7. I'm freaked out. The German roaches must be a whole other problem than what most experience on this tutorial. We are seeing many of them come out of the wood works- ones we have never seen in places we have never seen them. I'm getting so disgusted and don't know what to do!

While I think that it must be killing some, it seems to be just agitating the others and they search for moisture and food... and travel to uncommon areas. It's not like we see ten all in one place but more like one big one at a time in places we have not ever seen them. Any ideas how to battle that? All areas are fully baited and we are vacuuming and cleaning and continually killing ones that come out looking for food.

I keep seeing the babies in the kitchen area more than anything and know there must be a "nest" as you call it somewhere but can not find it. I wasn't able to get the dishwasher door off because it requires a special type of tool that I am not familiar with.

I did read that comment on the pasta water, I think I will go back and read it again... if memory serves me correctly, she "boiled pasta" more for making the mixture and as it was boiling, set out bait for the roaches to go to... since they were already out looking for food? May be worth a shot at this point.
Ninzerbean (author) in reply to TheMLBBFeb 1, 2013. 2:35 PM
Yeah, you are going to have to get to the nest - and it sounds like it is inside the appliances. This is harder than having a nest outside. Can you guys leave for the weekend and bomm the place? Maybe twice? I am really worried about the dishwasher - first of all it's a water source and secondly I am afraid that the stuff in a bomm (I am misspelling it so this message won't get caught up in the filters) won't get to it. Can you go somewhere and get the right tool? From what I have read about video games - see in the comments about the ps3 player that they had to take to a car wash vacuum place, I now am convinced that components (heat) and appliances (heat and water) are ideal habitats that have to be dealt with. Keep me informed.

We stopped seeing dead babies, in fact we didn't see any roach at all for about two days. Now, I've seen one more adult (about an inch long) that was basically having a seizure in my sink. Now, I am afraid the process will start all over again with it laying more eggs and the colony will keep coming back. We haven't found any egg cases and judging from where we see the bodies, they have to be behind the cabinets/counters. Which means we can't get to them to clean them up. The problem is that the way our counters are made make it almost impossible to seal them. In fact, the only place that the counter walls and counter top make contact is at the areas of support (corners and support beams!) The rest of the walls have an inch or more of space at the top. Not just side walls, but the walls in the back that lead into the space behind the cabinet and in the front where the counter top ends. Also, whoever drilled holes for the pipes seems to have used the largest bit imaginable for every size pipe. Some of the holes could fit the pipe 2 or 3 times! I've tried duct taping what I can, but it is a 30 year old apartment building with cracks in every thing and I'm kind of at a loss on how to seal them away. I'm very sorry I keep posting so much, but you seem very knowledgeable and so far the bait is the best thing we've found.
Ninzerbean (author) in reply to tgrsam21Jan 29, 2013. 4:00 AM
Expandable foam - get that for your pipes, it hardens and in my experience it is roach proof. The duck tape is not a good idea, the glue....yum yum yum for roaches. The can is only good for about two hours so plan ahead where you are going to use it. See it on some of my photos in the ible around sink pipes. How's it going now anyway, sorry I was out of touch there, then when I returned I forgot to write to you.
TheMLBB in reply to NinzerbeanJan 30, 2013. 7:12 PM
For the most part the pipes and cracks have been sealed with the expandable foam. I kind of went crazy with it one day... needless to say I have learned how to use it better...lol.
szen1 says: Jan 29, 2013. 11:22 PM
Hi, I've had some experience getting rid of german cockroaches and yes they do look disgusting. First of all, yes you will see more of them if the boric acid works because it dries them out so they get desperate for water. They can drop their egg sacs too which hatch later. I have also read that some do learn to avoid the bait so just a few can survive and then start multiplying again. So, you may not see them for weeks, a month even, and then suddenly start seeing them again. You can get rid of them but it will have to be an all out war probably for at least six months and longer as a preventative measure. They can eat anything, but they absolutely need moisture. That is why they congregate in kitchens and bathrooms around the pipes.

Sealing everywhere a pipe goes in a wall is helpful. You can also dust some boric acid in the wall before sealing for good measure. That you have seen them in your appliances is not good, but that they seem to have limited themselves primarily to your kitchen is good. With a bigger infestation they spread out farther. Because they are around pipes, I set out most of the bait close to them but all the lower cupboards usually get explored by them. They travel along crevices so the bait needs to be placed there for them to find it. Bait along the back of the cabinets every 2 feet or so. Also put bait along the crevice in the toe space where the cabinets meet the floor. Because it is possible they do learn to avoid it, so use multiple bait recipes.

You want to contain them while you are killing them so they don't spread out looking for healthier surroundings. Bay leaves repel them, so, after you put the bait out, put bay leaves where you really don't want them, like on your stove, in your upper cabinets, in and under your fridge, under your microwave, etc. You may want to put them in your bathroom where ever you think they might be entering. They are not dangerous except perhaps as a choking hazard if your children are very young.

I'll post a couple of other recipes in another post.
szen1 in reply to szen1Jan 29, 2013. 11:49 PM
The dishwasher probably holds some residual water that the cockroaches are attracted to. They don't like dishwashing liquid so maybe a squirt of that where the water remains would help.

I find using my liquid potion the best remedy but it's a pain because it keeps evaporating.

Cockroach Potion
24 ounces of very hot water
4 tablespoons of boric acid
1 cup of sugar

The boric acid tends to settle at the bottom so you have to shake the bottle. Even though it also separates a bit after pouring it is still very effective.

Cockroach Balls

1 part icing sugar
2 parts flour
2 parts  boric acid

Add enough vegetable oil, butter or bacon grease to form a dough. It will no longer be effective when it dries out so you have to replace it but it keeps well in a jar.

Another recipe is:
8 ounces of boric acid
1/2 cup of flour
1/8th cup of sugar
shortening or bacon grease to form balls
optional - half a small onion chopped

Although I haven't tried it they are also attracted to flat beer so that could be used instead of water in the potion.

Only tenacity can win the war against cockroaches.
TheMLBB in reply to szen1Jan 30, 2013. 7:09 PM
Thank you so much for all your help! I feel like I have been battling them for the past 16 months so I hope all this will finally get rid of them. I have definitely seen more of them come out, which does freak me out. I am trying to keep places dry but this house does hold moisture too. I try to air it out by opening windows and wiping off condensation often though.

Also thank you for the other recipes too. I will for sure be keeping those at hand because I don't want roaches- and I don't want them trying to trick me either. Ack...

TheMLBB says: Jan 30, 2013. 7:02 PM
Thank you so much for such a fast reply :) You are awesome! I've just been trying to keep battling this problem. I was finally able to completely finish baiting today. We spent so much time in the kitchen area I think we didn't do as good of a job through out the rest of the house. We did bait but not as well as in the kitchen. Anyway, we have been seeing results... not really typical of what I have read but I'm hopeful.
Day 1- lots of them seemed to come out to get the bait in the kitchen
Day 2- We still some but not as many... and we have seen a few dead
Day 3- Saw them really dying. We keep seeing babies so you are right, there are those stupid sacks somewhere. I have been able to find some of them and get rid of them but not all.
Day 4- Saw some in the bathroom which we normally don't. (I also had sick kids so no energy for blasting bugs)
Day 5- Today, finished baiting all outlets, door ways, and drawers, even into the ceiling where the fire alarm is located. Anywhere in the walls I could think of. In the bathroom where we never see them, the one plug outlet there is actually had some IN THE PLUG AREA(not just after taking the face plate off- SO NASTY) that apparently went in there to die. That freaked me out tons so I was given an extra push to get it all done. That was the worst looking outlet of the whole house which seems odd because we rarely ever saw them in there. I have vacuumed lots and will continue to do so.

None the less, I think the last place I have to conquer is the dishwasher door... like inside of it. I *think* this may be where these babies keep coming from.

I'm definitely finding dead ones and live babies. My husband said he killed two big ones in the kitchen this morning though. He says they acted weird though, going in circles. One he thought was a moth at first because the outside looked flaky- it just fell and he finished it off while I kept my distance. I think that means the boric acid did it's job on that one.

Staying hopeful that this will end. Still having the jitters when I go to the kitchen though.
TheMLBB says: Jan 27, 2013. 4:30 PM
Where do I start? We bought an 1105 sq ft condo, upper unit of a four plex just about 15 months ago. We had plans to remodel almost everything accept the cabinets... That was until we discovered the horror in the hinges and underneath the appliances... That is when I made the final decision that ALL THINGS MIST GO!!!!! Seriously I wouldn't have bought the place had I pulled the dishwasher out and looked under it. The image will forever haunt me. SOOOO, everything went bye bye... We did completely new flooring, cabinets, countertops, appliances.... Everything. We sprayed a ton of bug spray- the industrial strength- before moving in. Well, 15 months later we have definitely seen less but still way too many! They are German cock roaches, the pest control companies have not been great with advice other than keep everything clean, use bait traps, and spray regularly and that we'll have to always deal with them in our place. Before moving here, sails my neighbor, there re apparently 40 or so Hispanics living here on and off- it's got 3 bedrooms and one bathroom... We have 5 people here and it's cramped!!! Anyway, I have been told multiple times by pest control companies and others that "third world" natives just store food differently such as not keeping eggs in their fridge so this is when larva hatches and so on. We live in a diverse neighborhood. Ok, slightly side tracked, so Our appliances that are just over a year old have become the "it place" for these things that, if I used curse words, I would insert I front of their names.... My brand new appliances people!!!! Yes, I have had roaches get into the oven clock, yes I have in a fit of rage, shaken my oven then proceeded to take apart the back panel and even the clock portion to make the things suffer and die right before my eyes. Yes I hate hate hate roaches!!! Also, they seem to think it's ok to get into my dishwasher area(this was the worst area before we gutted the condo)... I have had babies hatch and one day I called my husband in a complete panic because there were 30 or so in my new dishwasher!! I even got crazy and sprayed bug spray to kill on the spot into my dishwasher... Then ran it through a few bleach cycles to clear it out!!! Luckily it hasn't been that bad ever since... I smoked them out of there like crazy! I sealed cracks around pipes and any holes... Still we couldn't go into our kitchen at night without shoes and we always turn the light on, pause before entering... Then hurry and stomp the heck out of whatever we see. I have decided to not enter the kitchen at all costs at night.

AND THEN... I was so desperate I began begging for a reference for a bug man that could rid the place of them For good. Got a food reference accept they came to do a free estimate, said it would cost $200 and they could get rid of them but more than likely they will come back because we are connected to other units who must have them too. I've talked to 2 of the 3 neighbors and they say they do not have roaches... The others speak Spanish and I don't know Spanish well enough to find out if they do.

Anyway, $200 bucks and them directly saying they will come back though unless all units do it, just wasn't going to happen. I did feel slightly comforted when he said it was not what he would call an infestation and that it probably was before we took over... So we did manage to at least kill tons of them just not all. (Also, one person said they found the roaches were living in the roach bait centers... We had that happen too... So dang nasty)

I was so glad to finally run across your 'ible as I have not found anything else out there saying they can get rid of these blasted things.

So yesterday we spent a good 2 1/2 hours for our tiny condo, mainly in the kitchen area... Baiting with your goo of doom. After reading all the comments right before bed last night, btw...never do that- you'll have night mares about roaches, I need to do a bunch more in depth work through out the entire house even though we have really only seen them in the kitchen and super rare even in the bathroom area.

I can't tell if it is working though because I have seen a bunch of babies out during the day light today... I will have my husband check tonight when they are usually scurrying across the floor, and countertops.

Is it normal to see them come out more after baiting? I keep reading comments that kind of suggest no, it's not. Even during the day yesterday I saw quite a few after baiting... One was dead in the boric acid powder though. Maybe they just don't like that we found their hiding spots?

Also, we did dust some areas with the powder, places kids can not get to and places we didn't necessarily want them to be attracted to since we didn't normal see them there. We still have trimming to put up on our cabinets(I know... 15 months later and we still haven't finished) so I also filled in the cracks above the cabinets with the stuff.

As another one posted, I am also pregnant and I freak out majorly when I see the blasted things... Talk about heart burn and anxiety at it's worst. My kids have probably thought that their mom was taken over by some monster because I keep telling the roaches, "prepare to die!!!!!" I want them to die a fast and horrible death! We don't usually talk about death in our house so much- my kids are still quite young- but when it comes to these pesky things... I am very open about wanting them to die!

Anyway, I will for sure update with joy if they are gone!!!!

P.S. I found your 'ible on Pinterest... Thank you to whoever it was that pinned its!!
szen1 in reply to TheMLBBJan 29, 2013. 11:27 PM
I meant to respond to you but my post ended up at the top of the list instead so please do read it.
Ninzerbean (author) in reply to TheMLBBJan 28, 2013. 3:05 PM
I think you are going to be fine. Reading the comments is so helpful because there is a wealth of knowledge to be learned from others. I don't suggest JUST using the power though as that will only kill them and they won't take it back to their nest to poison their friends and for the survivors to tell other roaches not to go to your house. I may sound like I have no scientific evidence to back me up - and I don't - but I still am a believer that anything that can live on toe-nail clippings in a sealed jar for 3 months is "smart" in a way to survive our attempts at extinction. When you think of how many beings humankind has eradicated from the planet without even trying, and then you think of roaches... well 'nuff said.

So anyway you are on a mission, and I know it will work. But I disagree with the tech who told you that you don't have an infestation. Granted, I was dealing with what is also know as 'palmetto bugs', which are not the German ones, but believe that if you see them in the daytime you have such an infestation that they are being crowded out.

So please keep me posted, I really care, and being that you are dealing with German ones, everyone else will be able to benefit from what you find out. Just remember to always follow the money when something does not make sense. Pest-control companies would not be in business if they were successful. That sounds strange but I think that people have been lulled into thinking that having roaches is normal.

As far as Spanish speaking neighbors go, just write what you want to ask them and do a google translate. Maybe you can translate this 'ible and hand it out to them. Something here is not making sense though, no one wants roaches and you have done so much to correct the problem... there is no cardboard in the house is there? I understand the German one's just love cardboard.

Anyway, seal everything in your pantry in ziplock bags, find out where they are coming from and half your battle will be done. And thank you for writing.
TheMLBB says: Jan 28, 2013. 3:55 PM
So glad to see you comment back! :) LOL... I'm kind of consumed with this right now. Well, we don't usually have much card board in the house, maybe just a few boxes with storage in closets that I haven't seen roaches in, most everything is in bins. I started putting everything into the air tight containers in my pantry a long time ago... but still need more containers. Oddly that isn't where I see the roaches either- so glad I don't. I'm sure there have been some somewhere around there but I haven't ever seen them there. Anyway, last night, my husband killed two bigger ones in the bathroom... which we never see them in there either. We did dust and bait in there and it's on the opposite side of the wall of the kitchen so I'm thinking maybe we block off their access? It just seems like more came out after we baited. We just assume that it's because they are finding the bait... but I haven't seen one today at all yet... that's better than yesterday and Saturday. Hopefully tonight there won't be any either.

About how long before you don't see them any more? a week?

**Side note, I was once told that not just the paper grocery bags bring in roaches but the plastic ones do too and contain roach larva... i used to save them for trash can liners... to say the least, I never keep them anymore.
Ninzerbean (author) in reply to TheMLBBJan 29, 2013. 3:56 AM
I think a week is normal to stop seeing them. But with your level of problem I am afraid that you have to stop with the powder, there is a nest somewhere and you have to poison the nest, the bait it going to be the best answer. Did you read the comment about the pasta water? That is so strange and there is an answer there for you too, I just don't know what it is. Yet. Constant vacuuming with suck up egg cases, be sure to do that every day. Maybe a shop vac where you can throw out the debris instead of wasting money on bags. They are just pretty noisy.

You answered really fast! Thanks, that is awesome. I just came home for my lunch break to clean more and found a fourth baby on the floor..which is now, also, under a cup! Any idea why I'm only find babies dead and not any adults? The ones on the floor are all very tiny! I found one under the sink, but I haven't found a single dead adult yet.
Ninzerbean (author) in reply to tgrsam21Dec 20, 2012. 1:26 PM
You are only seeing babies because they just hatched, the adults are gone. They are either dead somewhere in your walls or dead at the colony or just got told by their 'friends' not to go to your house anymore. Babies will continue to hatch as long as there are egg cases. Vacuum, and give your boyfriend a massage.
tgrsam21 says: Dec 20, 2012. 4:00 AM
Ok, I have a few questions...I moved into an apartment. (My first one ever.) I've been here about 5 months now. About a month ago, I saw one roach in the middle of the night when I went to the bathroom. It was running around inside the trashcan. One of the brown ones...tiny (baby?) Then about 3 weeks later, I saw TWO in the kitchen in the middle of the night! (GROSS!) One got killed, the other got away. These ones were bigger, but the biggest was still only....half an inch? Maybe a little more? Well, I immediately got the stuff to kill them and we put it behind the light switches, under cabinets, on pipes, and under the fridge and dishwasher. We didn't put any on tops of doors or behind paintings or anything because we didn't know if it would stain the apartment and we'd lose our deposit. Anyway, that was...Monday. We saw one roach last night that got killed...medium size. Then this morning, I woke up and walked into the kitchen to find 3 baby (?) ones on the floor. I put cups on top of them so my lovely boyfriend can kill them but when I did, they didn't try to run. They didn't run when the light came on and when I kind of swirled teh cup around with them in it..they kind of circled the cup but very slowly. (Like they were dying.) Please, I need your opinion. Do you think we have a serious problem? Were the tiny ones in the kitchen this morning there because they were dying? Does this mean the bait is working? Should I expect more bodies? How do I know the bait is working in general and about how long do you expect it to take to finish them off...will they ever be gone completely? We are fairly clean people...according to the office manager...certain bugs are seasonal. (we had ants for 3 weeks straight and apparently my apartment building is "notorious" for them.) So, I don't really expect their monthly bug control to do anything constructive with these. Since the ants, we don't leave dishes in the sink anymore and we wipe down the counters every single day. I don't really know why we have the roaches but I hate thinking I'm dirty or thinking they are crawling on me at night.
Ninzerbean (author) in reply to tgrsam21Dec 20, 2012. 5:06 AM
You are not dirty, don't be silly, roaches can live on almost, and sometimes even, NOTHING. They love glue on cardboard boxes, so get rid of those, vacuum every day for awhile and throw out your vacuum bag if you think there is any chance a roach egg case could hatch and babies make it back out of your vacuum. The adult roaches are dead or dying, they are telling the other roaches in the colony not to go to your house - but they lay those blasted egg cases all the time, until those babies can eat the death bait they will continue to hatch. They should die off soon, you can help speed this along be intensive vacuuming. Remember water and height, these are the two favorite places for roaches to hang out. A little smear on top of doors is never going to be seen by anyone but roaches, I would make sure you have all of your pipes coming into the house done very well and any holes coming into the house closed up with expandable foam. Get rid of any moving boxes or any cardboard you may have. It's gong to be fine. Just give it a week to work.

The 3 you found on the floor sound like good news, they seemed sick to me. Reading through the hundreds of comments really helps too. You are going to be fine, and your boyfriend deserves something special for being such a brave guy. I do not think you have a serious problem. Really.
SongWinter says: Dec 15, 2012. 11:50 AM
i did it with peanut butter and worked great ! i´ve noticed the baits aren´t gooey anymore,the peanut butter has dried out and they´re hard now.
Should i do new baits ? or moist them with water? will that make them ineffective tough?

thanks!
Ninzerbean (author) in reply to SongWinterDec 16, 2012. 5:54 AM
Hard is fine. Roaches don't care - they eat cardboard! They should stay effective for about 2 years. Water will not do anything, don't do that. You're fine.

The Old Fart says: Dec 10, 2012. 5:42 PM
I used to live in a motor-home and not had a single bug ever then I moved in with my girl friend and there are roaches everywhere. I hate bugs. When we moved I wanted to leave the electronics to sit while I get rid of the bugs but she didn't listen and moved everything inside. now they are so bad that they are everywhere even crawling on us as we sleep. I will be using your everlasting Roach-B-Gone Goo of Death in hopes that it works. I have tried roach traps and found they were living in them. I have been using pantyhose to cover my electronics to keep the buggers out.
Thank you for your info and all your work
Ninzerbean (author) in reply to The Old FartDec 11, 2012. 4:19 AM
Check out some of the comments, actually check them all out - it turns out that roaches will make a home inside the electronics. Take them all (wrapped up in garbage bags tight) to a carwash with those strong vacuums. You are going to have to open them up a bit.

You need to be vacuuming your place every day for awhile too. You have a colony living there, that is harder than just a few coming in from outside. This is major. I think that the roaches may already be inside your electronics.

Remember, they like heat, water, height. But you may have to start with a bug bomb. Then move to the goo of death. I'm really sorry for you, this will be a big job, but I am sure in about 10 days you will be roach free. But don't stop the constant vacuuming, you want to get those egg cases. Throw out the vacuum cleaner bags after ever major vacuuming if you are not sure that the vacuum kills them. Or store the vacuum outside. Keep me posted, I really care. I know how it is.

Every 2 years should be fine. Just make sure you do it right the first time. It takes awhile to be thorough.
WILLIAM ISAAC says: Nov 24, 2012. 6:25 AM
Hello, came across your site looking for a way to kill roaches. Followed all your steps and looked as if it might work. A week later we noticed they weren't being reduced like we thought would happen. Then I noticed the "THE BAIT" (That's what we call it) was hardening and losing it's smell. So I took some trading cards from my collection that are worth just pennies that have a good Glossy Finish and put some BAIT on them and every night for a month I took the cards with the BAIT on them and ran them under HOT WATER. This not only soften's the BAIT, but also makes the Syrup smell real loud. And the water just runs off the Glossy cards and does not moisten the card. (You have to use the Glossy cards or the cards with soak up the water). And in the end we have no mess because you can pick the cards up and move them and fit them in just about anywhere. I put approximately (30) of these loaded cards around the house and do the wetting before going to bed every night and after one month we have not seen one BUG! I just want to THANK YOU VERY MUCH for this wonderful remedy and I hope others will try the card trick because it eliminates the mess and is so universal - Thanks again and Good Luck!
Ninzerbean (author) in reply to WILLIAM ISAACNov 25, 2012. 4:27 AM
Well I am glad you came across this 'ible looking for a way to kill roaches rather than being sad you don't have any. It really is OK for the bait to harden, it will only really get hard if water is used and that is not the thing to use. It will get hard enough not to fall off where you stick it but even hard it is really OK, but all the same I am glas this card trick worked and that you shared it. Thank you.

3 weeks back, I bought a cabinet (second hand). I realized it had roaches. I cleaned it up very well but didnt throw it out. Since then i started seeing one roach a day. I gave lived in this apartment for 2 years and never had a problem. I bought sprays from OSH and sprayed the entire apt next day after buying the cabinet. It didnt work. On the 10th day, i called an exterminator and he has put Avert bait dry powder in places where he felt good and used only one maxForce FC roach bait station in the apartment. I felt that the bait station was effective but he has only put one in the entire apartment. I called him to put more but he says its enough. He said I have mil infestation.
I want to take more steps on my own. I am planning to order more Maxforce bait stations that has fipronil, do you think that will work or should i make the bait at home ? How long do you think it will take me to fix this problem ? will this problem ever get fixed ??

Please reply. I am in desperate need of advice as I want to control this before it becomes a bigger problem.

Thanks.

Hi! Here is my quick little scenario. 2 weeks ago I bought a play station 3 off craigslist. After it being in our house for about 3 days I noticed a small bug crawling on the wall behind the tv stand where the ps3 was sitting. I squished it and thought nothing more. Over the next few days my hubs and son said they had seen about 3-4 total around the same spot. I then found one the next day on my wall and instead of squishing it I put it in a bag for closer examination. Shoot its a cockroach!! So i get boric acid and any other kind of roach killer I could find and decked out my house. Then I got to thinking and it dawned on me to check the ps3, I took it outside and kind of shook it on its side to only have a TON of roach body parts fall out!! I was mortified! I started to vaccuum out the vents on it and just got an abundance of partial roaches. I removed the cover and there was a live on just staring at me!! Now I put some of that gel bait stuff you can buy at a store inside a crevice of the ps3 and then sealed the whole thing in a garbage bag and left it sit for a week now. I am going to use your goo of doom around my house even though i have not seen any since. But what are the chances that if I open the bag they are still alive? I am possibly going to place the ps3 in a bag with you goo!! thanks!
Ninzerbean (author) in reply to kllincolnNov 9, 2012. 3:19 AM
Oh that is just horrible. You see I told you they were smart. There is a very good chance the one inside the bag is still alive and that there are a ton of egg cases in there as well. I think you are doing the right thing though. The bait will kill the live ones, and any that hatch will die from the bait in your house. That is a creepy story.
kllincoln in reply to NinzerbeanNov 9, 2012. 8:18 AM
IT IS!! We have never had roach or bug issues other than the occasional fly or a random spider. Last night when I was watching tv there was one on the wall and one by the tv. The ps3 is still bagged and I have not opened it. This sunday it will have been bagged for a week. I cant open the ps3 completely since there are some sort of "key" screws that need to be removed. I called a few gaming places and they wont open it for me due to the possibility of them infesting their store. I got the stuff last night to make your goo of doom and I will post an update as to what happens!! Thank you for your article by the way!!
Ninzerbean (author) in reply to kllincolnNov 9, 2012. 8:39 AM
Try vacuuming the ps3 - outside of course or take it to a carwash, they have very strong vacuums there. I think that is your best bet. I am sure the people who sold it to your had no idea of the problem. Take it as much apart as you can safely do. I really feel bad for you, keep me posted.
kllincoln in reply to NinzerbeanNov 15, 2012. 9:22 AM
ok here is the end result. I got the security screwdriver bit and took the ps3 completely apart, after 1 week in a bag with nothing but poison and dead comrades bodies, I found 1 live one in the ps3. but I could not believe how many dead bodies were in there. I took it to a car wash like you suggested and spent like $5 on the vacuum to make sure every little thing was out. I made the goo of doom and pretty much lined my house with it. baseboard, backsplash on the counter meets wall, cupboards, the entertainment center it was sitting on, I even put it in the little roach bait things. I put 3 small drops inside the ps3 just in case I missed something. and needless to say I HAVE SEEN NONE!! yay i am so relieved I stumbled on your page. I was ready to move lol. I have passed on your page and recipe to alot of people now. THANK YOU!!
Ninzerbean (author) in reply to kllincolnNov 15, 2012. 9:54 AM
Whew! That is a story with a happy ending. I wonder why they like to be inside components. I hope more people will read these comments so they know that that is a place to bait, I better add it to the 'ible. Thank you so much and I am so happy I was able to help you.

Any substitute for the syrup?
Ninzerbean (author) in reply to PikminRedFeb 19, 2011. 10:06 AM
Karo syrup is cheapest I think, you can use anything you think the buggies will be attracted to; peanut butter, honey, simple syrup (2 parts sugar to 1 part water, boiled), maybe soft drinks? How about glue, they sure like that, but you will have to work fast.
KRod in reply to NinzerbeanOct 18, 2012. 5:23 PM
A couple of weeks ago I was boiling pasta and accidentally spilled some of the water on the floor. Before I could even get a paper towel to clean it up, roaches that were hidden were coming out to drink it like fiends! Remembering this, last night I mixed 2 parts boric acid, 1 part flour and boiled some pasta. I let the pasta sit 10-15 minutes so the water could thicken up, added it to the flour mix (just the thick water, not the pasta) and put it in a squeeze bottle. I really didn't measure how much of the pasta water I used, the consistency resembled a watery milkshake I guess! The roaches immediately were running to it from their hiding places!! It caked up pretty fast but that has not stopped them from eating it. This morning, it was like something I had never seen before. So many were out and about trying to feast on my mixture in broad daylight. Right now approximately 7 hours later, they are dying. Is it normal that they are dying so fast? I kind of expected this whole process to take a lot longer. Tonight I will blast them again and experiment with the consistencies.
Ninzerbean (author) in reply to KRodOct 19, 2012. 5:31 AM
This could mean you have a nest in your house, usually the nest is outside. Thousands and thousands will live in a nest and go foraging into houses and bring back food to the nest, and of course eat it themselves. The boric acid makes them sort of shred from the inside out, or blow up, anyway, they die, fast. So I don't think what you are seeing is unusual but I am concerned that you might have a nest inside your house. This calls for bigger measures, maybe a commercial fogger is in order to get things under control.

Anytime you use water in this bait, it will harden very fast. But of course this pasta water is what is attracting your bunch. They will learn from this though and I don't know how long it will work to draw them out.

I am still concerned that you have too many to deal with on your own. But keep me posted.
KRod in reply to NinzerbeanOct 24, 2012. 11:15 PM
Update: 6 days later
What a difference 6 days has made! I am still finding 4-5 dead bugs every morning. I ran out of boric acid about 5 days ago so and will be buying more tomorrow so I can thoroughly take care of the bathroom. I am finding dead adults and live babies in the bathroom.
I am hoping we do not have a nest in here. We live in a six-plex (like a duplex but 6 houses connected together). Our problem started when some unruly characters moved out of the first unit (we are in the 2nd unit). The landlord sprayed their place and I think it made them all come over here. I have heard of other neighbors having problems through the years off and on. The people who live in the first unit now have not seen any. I'll keep you posted on further results.
KRod in reply to KRodNov 11, 2012. 6:19 PM
They are gone!! I did some boric acid "maintenance" and bought the sprayable foam to seal cracks. We even found a half-dead black widow spider that we think might have eaten a poisoned roach! Thank you again for this info. I never thought we would be able to get rid of so many this way but we did it!
Ninzerbean (author) in reply to KRodNov 12, 2012. 2:27 AM
Yipee! Tell all the neighbors! Make some money - offer to do it for them.
Stazy1378 says: Nov 4, 2012. 9:12 AM
Ok.....we did it today. We used the ketchup and mustard bottle idea. But, didn't add water. I did a whole bottle of 100% boric acid (dollar general) it's about 3 1/2 cups and added karo and molasses and two cups of flour. I mixed in syrup until it would squeeze out of the bottles (after we chopped abot half the tip off of the bottles) and then I took had the bowl of doom and stuck a putty knife in THAT. So the three of us have been squeezing and spreading the stuff everywhere......man, I hope this wraps it up. I've got them knocked down already. My kitchen is a fortress as it is...but the suckers have been spreading out (just a few here and there) on the hunt for food and water. DEATH TO THEM ALL!
koadave says: Oct 25, 2012. 1:50 PM
Have to share what I just saw. We live in Hawaii, where there are 2 common kinds of roaches, the "B-52's" that are up to 2 inches long and FLY, and a smaller version that doesn't fly and prefers to live in the soil. Both of these hardly qualify as "roaches" to me, as they prefer to stay outdoors, and only occasionally wander inside. They don't hang out in the regular roach places inside and don't look for food. Lately we have been having a bout with German Browns, which love to live inside and scrounge food. Tried boric acid by itself, with minimal results. Today i mixed up some of this goo of doom, and thinned down the leftover so I could pour it on top of the scum in our septic tank. The solution hardly landed before the B-52's were all over it! I mean pushing and shoving each other to get at it! The germans were a lot more cautious, but within a minute or two they were at it as well. Further proof that this stuff works. I'll post later for how it goes inside. Thanks for the info.

GDParduhn3 says: Oct 5, 2012. 9:52 AM
has anyone tried adding a Sterilizing agent to your mix ,, ???


I have been using one and now switching to a new one,, you add a 1 oz bottle or measured amount to any other product/ sprays/ (your bait) and wala not only do they die but their eggs and and their carcass become a sterilizer against any other roaches making more babies !!

Roaches i have come to find out, eat their fallen comrades bodies so the more you taint them the better !!

which is another reason you don't see as many dead ones as you should.

--------------------

im not shure why but i spoke with a pest control service/ products sales shop owner and he stated that once you get the boric acid wet its rendered useless ,

However he also stated that diatamasous earth was useless agaist roaches as well and great as a cleaner..

i say the more the merrier as every colony probably has an ingrained "watch list " of sorts of what to stay away from.

For example, many will climb the walls to avoid a foggers fumes and stay at shoulder height just below the heat and above the cold narrowly escaping the cloud, ( i have only seen older large ones do this.)

(of course once found being intelligent i make sure they never share this information with the others.)

Ninzerbean (author) in reply to GDParduhn3Oct 5, 2012. 10:54 AM
That is NOT true about the boric acid becoming wet and becoming useless - unless the guy meant with water and dissolving. Anyway what sterilizing agent are you thinking of?
TrissieEtta says: Sep 29, 2012. 1:37 PM
Would this bait still work by putting into small plastic containers with holes in that would allow roaches to enter but keeping pets from consuming the bait? Would the roaches go into the containers to get the bait?
Ninzerbean (author) in reply to TrissieEttaSep 30, 2012. 12:41 PM
The whole point of a sticky bait is to put it in places pets can't get to. What would stop a pet from picking up a plastic container? Also the containers would prevent you from putting the bait inside the walls, on pipes, over doorways, behind drawers etc. It really defeats the whole reason why this system works.
HStich says: Sep 9, 2012. 2:42 PM
Hi! We recently noticed Smokey Brown roaches in our basement-turned-playroom. The room has walls, carpet, toys & school-things. We never bring food down, but last week my daughter let her cup leak with a little milk. Also, my mother-in-law gave us tons of boxes (many cardboard) of old books she's been storing and we are thinking either it started there or in our terribly messy gutters and leaf piles around the house. (I can't get my husband to do gutters for anything!) About a week or two ago we notice lots of tiny babies, some 'teens' and a few bigger ones. I freaked out and cried "Infestation!" I immediately bought boric acid and gel bait and put it out. Still saw a couple babies and a big one and then came across your site. Put your paste out last night and checked back when it got dark and the hubs saw two big ones on the wall and left them, as they were near some bait. But I haven't seen any today, even dead ones. (I also put some bait all on the back porch, as the dog's food attracts them like crazy, so we need to figure that out... My point is, I'm worried that I'm seeing very few roaches, since just a week ago I saw one down there every time I turned around. (I saw a couple in the upstairs, but nothing like the basement.) Since I haven't even seen dead ones, should I worry? Are they dying in the walls? I guess I should be happy that they are few all of a sudden, but I'm worried for some reason. Could it be that fast? Maybe my infestation wasn't like I thought? Or are they meeting to form another plan to invade my house?! Thanks, by the way! :)
Ninzerbean (author) in reply to HStichSep 10, 2012. 5:09 AM
You are OK, the roaches have to eat the food to die, they usually eat some and bring some back to the colony. They die a slow terrible death so it is not like you would put the poison out and see dead roaches in a hour, more like just what you are seeing.

The dog's food is another story and one I will have to think about. Well there are some obvious ideas but I am sure you will think of them too.

I think the cardboard is what brought them to your basement, not the spilled milk, or even if there was a bit of food, it would not matter, but the point is that they won't come back - you must do a really thorough job though, it takes time and effort, but it should last for a few years.

My house up in the woods in SC is finally safe from roaches, I only ever see an occasional dead one. It's spiders I am contending with now.
HStich in reply to NinzerbeanSep 14, 2012. 10:26 AM
Good luck with the spiders! I feel like bugs have just been invading us lately! One more question, though I know you aren't a professional bug researcher. ;) I'm not seeing anymore (besides a dead one here or there) in the basement, but all of a sudden I'm seeing 8 tiny babies a day, UPSTAIRS, all in one spot in the kitchen. I'm constantly killing them. I can't tell from where they are coming, but they are always in the same spot and there are usually two at a time. It's driving me crazy. Does this mean it's working you think? Or is this a bad sign? Thank you so much for your comforting advice!
Ninzerbean (author) in reply to HStichSep 14, 2012. 1:49 PM
Hmmm I would say to do your kitchen again - did you pull the drawers out as far as you could and put the bait on the back of them? Babies mean egg cases, I don't know how long they take to hatch but you must have a slew if you are seeing them every day, the cases are somewhere where your vacuum has not reached. Vacuum again. Not a real bad sign, it just means you missed somewhere.
mpatton6 says: Aug 9, 2012. 6:28 AM
This is just not working! I applied it Sunday everywhere and it is Thursday, now I'm seeing them in day time and all over my walls when before I had only been seeing them at night. They have also gone to the upstairs bathroom when I hadn't seen them there at ALL! : (
ZaneEricB in reply to mpatton6Aug 20, 2012. 10:38 AM
I talke dto a Pro the other day about other options besides poison....

He said Crushed Bay leaves = keyptonite for roaches and

SALT your carpet.

Your problem sounds a bit more intense though and may require a professional....
Ninzerbean (author) in reply to mpatton6Aug 10, 2012. 1:11 AM
Please go over the 'ible again to see if there is anything you missed doing. Seeing roaches in the daytime means they are being crowded out of their colony and means a really bad infestation. Are you getting rid of anything that could be harboring a colony? Check your under the oven area - maybe there is a pull out storage place? Really this stuff works very well, but you must do your part and thoroughly clean too. Is is possible the colony is actually living in your house - and you will have to find it. This is very rare. Truly it is unheard of for this stuff not to work. Please let me know any more details so that maybe I can figure out why it is not working for your situation. It does take a long time to do it correctly in an average size house this could mean 2 or 3 hours - do you think you have done a good job? Have you read any of the comments or all of them to see if you can glean something there that may apply to your situation? I really want to help so let me know.
ZaneEricB says: Aug 20, 2012. 10:36 AM
I have to admit I was slightly skeptical, but....If I see a roach its dead now!

I used the basic formula you suggested, but I decreased the amount of flour and added alittle water so I could use a caulk gun to apply this roach terminator to pipes, nooks, crannies, and other various roach homes. and just to make the smell more roach freindly, and cheaper, I used molasses.

This stuff was thick, smelled great(hard not to taste it... :) ) and kills roaches and wards off ants. I had all the ingredientsand this was too easy not to try.

Thanks for the help!
Hatebugs says: Aug 10, 2012. 9:21 PM
I don't have any roaches (thank goodness), but I am very paranoid about the possibility of getting them. A couple of my neighbors have roach and mice problems in their homes, and I worry. I have a detached garage, and I did get some mice last winter, but I also found quite a few dead ones after I put out some stuff I picked up at Home Depot. No signs of mice or roaches in the house, but I am very paranoid. Is there anything I can do to make sure they stay out. Since I moved in less than a year ago, I still have some unpacked boxes in my basement, but I'm slowly going through them. I was thinking of trying your Death Paste as a "just in case," but I'm afraid that if I don't have either in the house, that the sweet mix will just attract them. I want to keep them away, not invite them...even if it is to kill them.
Ninzerbean (author) in reply to HatebugsAug 11, 2012. 5:25 AM
I really think it would be best to use the bait even if you do not have roaches, it will not attract them to your house any more than nail clippings and crumbs or cardboard would.

As far as mice and rats go I have been so impressed with a $30 device I bought from Home Depot that plugs into an outlet, you can use an extension cord to place it anywhere if the outlet is not close enough for you. I had rats and mice in my old house when I first moved in. They ran around in the ceiling at night and it was terrible. I bought one of these things and the problem was solved immediately. I know it works because I had them in the garage loft - I found the droppings - and I put one up there too, the reason I know it works so well is that about 3 years later I found droppings and checked the "ratinator" and it had burned out, the little red light was off. I really like this little device because the dogs can't hear it, I can't hear it - even when I put it up to my ear, and it really works. You don't want dead mice or rats in your walls stinking up the place, this thing just makes them go away because it makes a hight pitched frequency they don't like. I hope that helps - and I wish I knew what it was called, I just call it the "ratinator".

lind2176 says: Jul 17, 2012. 6:22 AM
Thank you very much for your detailed how-to!
Here's my background before asking my question:

Just recently moved from the Pacific NW (which has no cockroaches, not where I'm from) to Georgia. The hubs and I have moved into an apartment and, you guessed it, we are experiencing cockroaches. Most of which I have seen either on the kitchen floor or the bathroom. Our apartment gets sprayed inside every other month. They sprayed last week, and already just this morning I saw one sprint across the kitchen floor. I'm beginning to wonder if the spray they use really works, so I'm going to give your method a try.

I'm going to take your advice and take off the switchboards, put it behind the drawers, and around the pipes. I'm trying to think of any other places in the kitchen to put it, but running out of ideas. If you have any other ideas, please let me know. We don't have kids or pets, so we are not too concerned about the toxic part of it.

Here's my question: once I apply this "goo of doom", should I be prepared to see more cockroaches due to the attraction of the paste? As ridiculous as this sounds, I'm almost more comfortable killing a few cockroaches individually throughout the week rather than seeing big groups of them. Now that I'm thinking about it, I'm getting real nervous just thinking of the new group hang-outs I'll be making for the roaches. Or do they eat and run?

If my memory keeps up with me, I plan to post a follow-up. Thanks again for all of your help.



Ninzerbean (author) in reply to lind2176Jul 18, 2012. 6:42 AM
No, strangely you will not see piles of dead roaches. I think they take the food back to their community and most of the time they die there. After I apply the bait I may see one or two dead bugs - and I believe they are the ones that made me put out the bait in the first place.

Another good place to put the bait in your kitchen is anywhere up high - on top of your cabinets if that is possible. Just think about hight places and wet places and food and cardboard places.

This is going to work. Think about it - your exterminator comes every month, if you didn't have roaches why would he come? You would let him go. That is why what they use is made to not work very well, and certainly made to not last a whole month. When in doubt about anything that is a puzzle follow the money.

Thanks for writing and I hope you will follow up.
lind2176 in reply to NinzerbeanJul 27, 2012. 12:50 PM
Okie doke, it's been almost two weeks after applying the Goo of Doom in all of your recommended places and here is the result: no more live cockroaches! WOOHOO!! We have seen three so far, all dead. We are loving this, and feeling much better about our situation.

It's kinda funny, when we put this all together, it smelled like a maple bar donut lol. No wonder the bugs would go for this stuff! Thank you very much for all of your help and for this recipe. I am spreading word around about this stuff, because being in the South, we definitely aren't the only ones with a cockroach problem.

Thanks again!

Esmagamus says: Jun 24, 2012. 7:05 AM
I hate having bugs around the house, all sorts of them. Ants, flies, mosquitoes, roaches.

So, this time, I went all the way and bought myself a bottle of industrial (used in restaurants), permanent, non-staining bait. All I have to do is mix a cap full of the stuff with two litres of water and spray it everywhere. Every time we see roaches, they're dead. And so are flies and ants. Have I mentioned there are no spider webs anymore?

Looking at the sort of trouble you had baiting your home, I'm glad mine is made of stone and doesn't really have hollow walls and crawlspaces.

Hope you get rid of those pests permanently. Your house is lovely.
RoxieLynn in reply to EsmagamusJul 6, 2012. 3:18 PM
I would like to know the name of this product also. I have tried several sprays which seems to feed them instead of kill them.
Esmagamus in reply to RoxieLynnJul 6, 2012. 4:43 PM
One thing you'll notice on the domestic insecticide sprays is that the active ingredient concentration is below 1%. So, not only they are not very poisonous, they'll also dissipate quickly. What one needs with these persistent infestations is a poison that will stay there when you're busy doing something else. It is also important that the insecticide is present in sufficient quantities and takes a longer time to act than sprays so the bugs will have time to carry it back to nesting areas and poison whole colonies.

Again, I don't know what you will be allowed to buy, as these products are very poisonous to fish but any permethrin based product will do a good job as it is both poisonous and repellent to insects. Toxicity to humans is also low and I know it is common practice in the US to soak military uniforms in the stuff.

If you do want sprays to kill airborne insects, there are machines that take special cans of spray insecticide and release a puff every few minutes. Those sprays have higher concentrations and will kill flies instantly.

Do a thorough cleaning of your home, especially your kitchen. Rip the baseboards under the cabinets, wash that hidden area thoroughly and apply permanent insecticide, plus rat bait and ant bait to create a denial zone. If you force them to seek alternative routes, they will show up where you can see them.

If your home is made of wood, you'll have to have additional precautions that I am not qualified or experienced enough to give, as homes in my area are exclusively built out of masonry and thus have no crawlspaces or access to insulation areas.


Go to a farmer's supply warehouse and I'm sure they'll have the stuff I'm talking about in powder or oil emulsion form. They usually spray cattle pens with it.

I can't stress this enough: follow the manufacturer's instructions, watch out for contamination of food preparation surfaces, fish tanks, etc. Be responsible and in doubt, ask and use common sense.
Ninzerbean (author) in reply to EsmagamusJun 24, 2012. 2:58 PM
But wait wait, what is it? I have moved into the woods, I feel like I have made a huge mistake that I can't get out of, spiders every where, bugs that I have never even seen before or knew existed, and I baited with my stuff and it worked great and then this morning a roach just drinking water out on my deck.

I dumpster dive and there are funny little roaches on everything, I have never seen this before. I am so deep in the woods I can only talk on the phone outside on the porch. I hate bugs. I feel like a prisoner in my house now, I have been so attached by chiggers I think I will have scars for life. My dogs are fine, I am not. What did you use, how can I get some? The spiders here are out of a nature channel show. The mud wasps even build their nests on door handles.
Esmagamus in reply to NinzerbeanJun 25, 2012. 1:35 AM
I suspect you're carrying eggs home with your dumpster diving. Do get some sodium hypochloride solution (13% concentration bleach)) and thoroughly disenfect all you're bringing home.

I can't tell if the exact product I used is available on your area. I used a Bayer product but, since I'm away from home the whole week, I can't tell you the name right now.

Any decent farmers supplier should have a permethrin-based insecticide for wall applications. Cattle farmers usually spray any fly resting place with the stuff. They touch it, they die. That's the sort of product I'm using. I mix a sprayer full of it and coat every surface with it. Walls, under cabinets, on top of cabinets, around baseboards, under stairs ledges, around windows, doors, drain holes, ceilings, you name it.

Pay attention that the stuff you buy is non-staining. I will give you that bayer product name when I get back home. :)
Ninzerbean (author) in reply to EsmagamusJun 25, 2012. 6:50 AM
I'll bet you are right. I use my leaf blower and sometimes the pressure washer on the stuff but it must not be enough. I know where there is a feed store so I will go there, thank you ever so much, you don't need to get back to me with the name, knowing it is permethrin based is all I needed to know. And non-staining.
hollyglo says: Jul 2, 2012. 12:08 AM
First of all, thank you so much for this. I'm simultaneously roach-phobic and very antsy about pesticides (plus we have a dog who crawls around everywhere), so it was such a relief to find something that works without poison.

I moved to North Carolina and had never even seen a cockroach before in my life until we realized our kitchen was infested (mildly, but still). We followed your instructions and baited the whole house. We never saw an adult alive after that (I once opened an unused drawer and found three huge dead ones—ugh), though we continually saw young ones that had presumably not yet gotten to the bait. The house was old, and the landlord wouldn't do his part in maintaining it so it wasn't a prime roach habitat, so we ended up moving. Our new house is newer and easier to keep clean, but there are tons of cockroaches outside at night. I don't know if it's common to see them on the outsides of houses here or not. They look like woods cockroaches based on Google searches (they don't breed indoors), but I've seen one or two that looked like German or American, and some huge black ones on the shed at night (Oriental?). We were very careful when we moved to clean and inspect everything, and we left any suspect appliances, so hopefully we didn't bring any inside from the old house. We didn't have time to bait until this week, so in the meantime I set Combat bait out, out of my dog's reach. We're going to do the big baiting job in the next couple days.

My question is, does it make sense to bait outside as well? Would it work to put some bait above our exterior front door, which is covered by a porch? What about our shed? My only worry is that having it outside would mean critters like birds could eat it, and I definitely don't want to hurt them. I just like to spend time on the porch, and I don't want cockroaches joining me—and I'd really like to prevent them from taking much of an interest in entering the house if they can get to some outdoor bait, take it to their nest and never return.

Boric acid is so benign to everything except bugs that I think you will be fine, the way it works could never work on an animal, it wont poke holes in their skin. But animals also won't be attracted to it and it will be put in crevasses that an animal can't ge to anyway. Go ahead, it will help, but it won't be the cure-all it is inside. The big black one's are called water bugs. I have seen them before, gross beyond words.

Remember to be vigilant about cardboard coming into your house - get it out as fast as possible. Use any opportunity that a hole is cut into a wall for what ever reasons, to bait that area. I am having a mess of work done on my house and am jamming bait everywhere. In this heat it tends to melt so try to think of gravity and melting temperatures when applying.

I am sad and disgusted tonight.! I work late; it is very unpleasant to turn the lights on to find roaches every night. It is equally upsetting to discover that the small apartment you rented 4 weeks ago has an ongoing infestation of roaches. While I see the occasional small one, most are the disgusting Palmettos; mind you, this is a $1000 a month rental in an area of million dollar beach homes - Isle of PalmeETTOS is what is should be called. Like another post, I too have heard, 'it's SC'. SHOVEL it elsewhere, this is gross! In fact, I am so upset with seeing 2-3 nearly each day, now the slightest fruit fly is freaking me out! I did buy traps - sometimes I am lucky and I do find them dead. There is actually a mirror here, it has shells painted around it; and it has a roach painted on the glass - it is not attractive. I did not put it here. I want to put a post-it note over it. I already bought another product; I will spray tomorrow before I leave for work. If this doesn't work I will ask the Landlord to try your product - I have not the strength for this. I have long hair; everytime it moves and tickles me I think ROACH! I am sitting and I catch one out the corner of my eye - gross. Last night, while washing up for bed, in the mirror (a different mirror) was a reflection of one crawling on my shower bar. I check in my bed each night, for fear one is there. I turn the vaccum on constantly (it has become a fixture in my living room); and I don't care if it bothers my Landlord above! What a nightmare. I want out of my lease. If all of SC is like this I am happy to move - seriously. So sad and YUCK!!! Thank you for allowing me to vent here - I hope this is allowed! Great article too!!!

Hi , i been living in my condo for 5 years now and when i first moved in i demolished the whole kitchen, bathroom , i changed the floors i put everything brand new , after a year i started to see roaches i think i got them from the next door people, then i told the manager and he sent a exto and put some gel then i only saw a few but then as time passed i started getting more and more and now i have a lot and its annoying me i can't stand them , i tried ur recipe but i still see them , well not like before but there still there crawling around i did what u said to do , do u think that since the next door have them i will always see them in my condo , i just want to get rid of them for good i have 4 kids and they get scared when they see them , i don't like eating at my place or sleep in my bedroom anymore there all over the place. Pls i need ur help what should i do.
Ninzerbean (author) in reply to xena1356Jun 21, 2012. 4:08 AM
Somehow your message did not get to me until now. There is no reason you should be seeing roaches, really. Is there any way for them to be coming from next door that can be blocked off? They have no bones and can get though the smallest of cracks. Those cracks can be sealed up with expanding foam. I can only suggest that you bait again and do a more thorough job. Did you pull out all the drawers and bait behind them? Have you read through all the comments and seen any advice there that may help? I swear this works - I just moved to SC where everyone here seems to accept the fact that there are roaches, but I don't! I had the house for one month and there were roaches everyday. When the house was buit they had pipes installed into the walls and used the exterminator to shoot poison into the wals. I had them come and saw some dead roaches after 2 days. Three days later there were plenty of live ones, I used my bait and now they are all gone. It really takes a long time to bait your whole house, please try again, it will work.
Kuvisha says: Apr 11, 2012. 3:08 AM
Hi!

I just moved into a new apartment and the place is crawling with roaches! YUK!

I have a feeling that the whole building might be infested, do u think this is still a good idea because i don't want to attract them all to my unit, i"m grossed out enough as it is but desparate to be rid of them for good!

Please please help!
Ninzerbean (author) in reply to KuvishaApr 15, 2012. 6:23 PM
Yes, of course! Read all the comments, it is a great idea. They are pretty smart buggers, they will spread the message to stay away from your place. You won't attract any more than are there and you will see results right away. Don't worry, it's going to be fine.
sbarton2 says: Apr 8, 2012. 6:23 PM
Just moved into a rental property a few months ago, the place was crawling with roaches. Used this recipe and I've only seen a few tiny cockroaches since. Great tip!
Ninzerbean (author) in reply to sbarton2Apr 9, 2012. 3:42 AM
Oh do it a quick touch-up, you shouldn't be seeing any. Maybe you missed a few places? It is a BIG job to do a whole place, but of course the pay off is BIG too. Thanks for writing!
Bakesalee says: Apr 1, 2012. 1:10 PM
I'm not concerned about toxicity - I am concerned about using anything that will actually attract roaches into my place (honey, syrup). Puke! How am I supposed to live? I saw a big one by my bathtub when I was sitting down to pee last night. Luckily I have a girlfriend who has her own apartment so I could leave. I'm back home now, but I'm not feeling good about it.
Ninzerbean (author) in reply to BakesaleeApr 2, 2012. 3:57 AM
Silly Bakesalee - the roaches are already there at your place. You need the syrup to lure them to the stuff that will kill them. Then they go tell their buddies and roaches will both leave and get the message not to go back to your place.
I'm at my mom's house now (in Florida), she is a bit of a pack rat and there are a lot of cardboard boxes and old books and what not - BUT in two weeks here I have not seen one single roach. She used my formula about two years ago.
kill-a-watt says: Oct 16, 2010. 12:04 PM
Well my Dad had an infestation, so I was able to try this recipe out.

I mixed it in a old plastic takeout tub. We wrote "poison" on the sides and top.

He only let me do the kitchen, and the first few weeks we had no progress. A week later I did the entire basement, reaching up  to smear some goop on each of the overhead beams. That (and perhaps waiting) made a huge difference.

Now, he only sees a very tiny roach like every three days. Amazing.

The only change I did was to add a bit of water to make it more spreadable.

I'd recommend going to the dollar store to get a paint scraper. It will come in handy to stir the recipe and to put a little dab of everything everywhere.

I still haven't done behind the switchplates yet. Maybe he'll let me now.


I'm going to do this for myself, in my own home as a prophylactic measure. ;-)
Ninzerbean (author) in reply to kill-a-wattOct 16, 2010. 1:41 PM
Great feedback, thank you, if only he would let you do the whole house...
kill-a-watt in reply to NinzerbeanJan 29, 2012. 8:00 PM
I'll do a follow-up here and say that he hasn't seen a roach in over a year. I think we got them all. Since for the first 30 years of my life I can safely say there were zero roaches in that house, I don't expect a re-infestation unless my Dad gets real unlucky again (we think they came in on a bag of onions). The onions were in the basement, so maybe that's where the reserve roaches were coming from. Hitting all the overhead beams perhaps killed the basement ones too.

I did go and put a little dab on all the U-traps on all the upstairs sinks. All that poison is still there, so we should be still protected.

Just think if you could smear a bit of this stuff on every 2x4 while your house was being built.
kill-a-watt in reply to kill-a-wattJan 29, 2012. 8:29 PM
also, I found 5 oz bottles of boric acid powder at Dollar Tree, for a dollar. The powder is 99% and dyed blue. One bottle was enough to do the job. I bought extra because it makes good brazing flux too. (see http://www.youtube.com/watch?v=Ij_z-JY0nU4 )

I want to emphasize to slowly and carefully mix the boric acid up, as it's easy to kick it up and breath some of it in. I had a bit of a cough for a few days afterwards that I still recall even though it's been over a year. Once it is all mixed, it will be a like putty and the inhalation issue will be gone.
Ninzerbean (author) in reply to kill-a-wattJan 30, 2012. 3:25 AM
Thanks Kiil-a-watt,
I will add that part to the instructions. I'm happy for your dad finally too, I was worried when he wouldn't let you do the whole house at first. I wish it was not blue because my house is for sale now and I have to go around and wipe up all the blue that dripped because the last time I did a retouch I forgot to add flour and it never hardened up.

I totally agree that a house should be treated while it is being built. Why don't you start a little business when the housing market turns around?
strmrnnr in reply to NinzerbeanFeb 25, 2012. 3:11 PM
If you could make the mixture to go in a refillable chalk gun, or pre-filled tubes, you would really be able to do a slick job for new construction
millerck in reply to strmrnnrFeb 29, 2012. 2:49 PM
A squeeze bottle like a ketchup bottle or a restaurant style condiment bottle works really well. You just have to clean it out really well after use.

I've used similar type bottles for various things. Just make sure to label them appropriately to avoid cross contamination. Even cleaned out, it would suck to use a borax paste applicator for a mustard bottle. I can't see that going to well. :)

You are so welcome, sometimes I think because we live in such a 'new and improved' age that we forget about the things that worked perfectly well without being improved, and it makes us feel powerless because we don't think we can improve things ourselves without the help of a professional. Then to find out that the professionals are only working to keep themselves in a job by using a poison that will make the roaches only go away for a month so you think you are dependent on the 'professionals'.

This method of using Boric acid and a sweet substance has been around forever. I remember my great grandmother using it when I was a child. The reason it works? The Boric acid when ingested will bubble up and and whatever digestive system the roach and or ant has explodes internally. She mixed Boric acid with just enough honey to make a think paste.  She saved soda bottle caps to use as containers which she placed in cupboards ect. Also next to ant trails.  Sometimes the old fashion way is the best way !
Ninzerbean (author) in reply to Art-tartNov 21, 2011. 4:50 AM
How true! Most people have been brainwashed into thinking they have to rely on a pest-control company - for pest-control that just makes the roaches and the pest control company come back every month. I like your Great Greandmother's idea of the bottle caps for certain places where little curious hands and little dogs can not get to them, but it's pretty easy just to smear it behind switch plates and on top of pipes. Roaches like to be up high and some places it's just not possible to balance a bottle cap. Thanks for commenting.

csprinkle says: Sep 1, 2011. 11:04 AM
I live in Mazatlan, Mexico, where we have what are called "American cockroaches".
They are about 2 inches long and about 3/4" wide at their widest. No exaggeration. We also have tiny ones, about a half inch long. They are ALL disgusting, but those big ones scare the hell out of me. I woke to one crawling on the back of my leg and thought I was gonna lose it!
Thanks for posting this instructable...I'll be buying boric acid -- and by the way, you can get boric acid in most pharmacies in the US. No prescription required, but it's usually kept behind the counter and you'll have to ask for it.
Semper Fi Barbie says: Mar 19, 2011. 9:37 AM
This is awesome! I just moved into a new house last month. Unfortunately, my roomate brought roaches with her. Its not that I can't stand roaches, I can't stand them in my kitchen. And it grossed me out that they started living inside the microwave. I am from Southern California and now live in Florida so I've never seen this before. I think I am gonna give this a try since my furbabies can't keep up with the roach population.
tmorris13 in reply to Semper Fi BarbieAug 8, 2011. 1:27 PM
Unfortunately, they are in Southern California, as well. I know, as we now have roaches. We think they traveled down from the upstairs unit, since they showed up shortly after our neighbors moved out :( I'm hoping this instructable will help us.

Thank you so much for this. I'm going to apply this as soon as I get home. I have not seen any palmetto bugs since I but Boric acid by itself around the garage, but I am having trouble with German Roaches. They are everywhere. I bought some boric acid from a Family Dollar store here n Houston. They sell it for $3 in case somebody is looking for it. It's 100% boric acid and it's a pretty good size bottle. It's in the poison section.
Gonna try this out. Thank you so much!!!!

Excellent 'ible! And those sculptures are a riot.
I caught on to Roach-Pruf back in the States, some time in the '70s or '80s. Loved it, but I always just used the straight dust. I even treated the Chinese restaurant I was working at at the time--one afternoon I pried the wainscotting off the walls and dusted behind. The owner never knew why the roach population dropped so dramatically. My inspiration came the day I placed water glasses for a four-top and one of the ladies pointed out that one of the glasses had a swimmer. Embarrassing, to say the least. But the restaurant got a free treatment that the owner never knew about.
I've moved on since then, and now live in Taiwan, where I can buy boric acid (way cheap!) at the local chem shops.
I think I'll try your sweet bait system; it sounds better than what I've been doing all this time.
Thank you!
Ninzerbean (author) in reply to milesfromneihuFeb 13, 2011. 10:43 AM

Furballs says: Feb 6, 2011. 5:45 PM
Veery interesting. My 11 floor apt. building is infested with German roaches, by far the most common ones here in Canada. Luckily they don't lay eggs around the place, but they do drop those cases full of tiny new roaches everywhere. UGH ! It's not possible to completely eliminate sources of food and water in a place like this, and besides, I read an article that claimed one roach lived over a month sealed in a glass jar with one human hair and no water. No info on how long the hair was but even if your home was close to sterile, they'd still find food, I think. I hate 'em, but I've had to get over the creepies, or never sleep, cause I've lived here over 20 years. The current landlord is a jerk who won't do pest control. I've been using diatomaceous earth, which really does work. But it is kind of slow, does not stick well on vertical surfaces, and it's really dirty looking. My floors and cupboards always look kind of dirty and dusty because of the D. E, and it's always getting stirred up into the air, and it's not good to breathe it, I know. I had heard of boric acid but did not know it was so effective. The newest gel paste that the pest control companies use works but costs a fortune. I think I paid over $60. for one tube of that stuff. No way I could afford that. Because I'm constantly getting new roaches from all the other apartments, I've been very discouraged, but your paste sounds very doable and far less messy. Soon as I find some boric acid, I'll let you know what results I get. Funny, I remember my grandmother used to use boric acid wash for the eyes if you got dust or something in them when I was a kid and even though it's no longer sold for this purpose, clearly there is little to worry about in terms of toxicity, even for my cats, should they manage to catch and eat a sick roach. Something I hope I never actually see happen :-).
Ninzerbean (author) in reply to FurballsFeb 7, 2011. 4:05 AM
I agree with you about removing food and water - that is impossible. This will work, do it right away for right-away relief. The roaches will send signals to the other roaches in your building not to go to your place, they are very smart. You may even want to post a link to this 'ible where all the tenants can see it. Then the whole building could become roach-free. Just read all the comments, you will understand how important it is to be thorough.

Ninzerbean (author) in reply to WeissensteinburgJul 26, 2009. 11:40 AM
Well be sure to ask if they do any baiting. If you don't have bugs you aren't gong to call them - they know this so it's not in their best interest to get rid of the bugs for very long.
Weissensteinburg in reply to NinzerbeanJul 26, 2009. 11:44 AM
Not in our case, we've had an annual contract with them, and they have to come out as often as we call them. They do our termites checks and all the regular things, too.
Ninzerbean (author) in reply to WeissensteinburgJul 26, 2009. 12:35 PM
That's what I used to have too, I think this old house was just too much for them because I was calling John every week and after a few months of that they started putting me off about his coming out, making excuses, not calling me back, etc. I was not used to living in a house where I was seeing roaches and I wasn't going to put up with it.
jack8559 in reply to NinzerbeanNov 10, 2010. 8:00 PM
It sounds to me that you should have ended your contract with them immediately and asked for a partial refund for the rest of the year - If you aren't going to do the job, I want my money back NOW!!! Great instructable BTW!
Ninzerbean (author) in reply to jack8559Nov 11, 2010. 2:32 AM
Yep, I should have done that but there was more to the story that revolves around termites,and them drilling holes in my patio and ruining the look, it took a year to resolve, I die prevail but it was tons of writing letters and getting second opinions. Thank you!
platinumluv says: Oct 6, 2010. 8:11 PM
oh, one more thing! when i moved here, i forgot my can of Roach Prufe, so i got another brand of boric acid. The granules of this one are really more big, kind of like salt instead of the fine ground powder of the Roach Prufe. Do you think the finer one is better? Thanks!
Btw..whenever i see a picture of a roach on a website, i have to cover it with my hand -i can't bear the sight of them in pix too, lol!
Ninzerbean (author) in reply to platinumluvOct 7, 2010. 3:49 AM
Hmmmm, I don't know, it doesn't sound to me like you are using it to make the bait. Get the real stuff and make some bait. We sound a lot a like in our fear.
platinumluv says: Oct 6, 2010. 8:04 PM
Hi..i really want to thank you for this article. I was looking up ways to control a roach problem that sems to come and go in my apartment, and i stumbled upon this site and your instructable.
I learned of boric acid a number of years ago, and everytime i moved into a new apartment, i was armed with a caulking gun & duct tape (to seal off every possible crack or crevice i could find, sealed off the areas around the pipes) and my can of Roach Prufe. I would sprinkle the boric acid into the cracks, baseboards and such, then seal it up with caulk. it literally would take me an entire day to do that, but it always paid off. Until i moved into this apartment....
I keep my apartment spotless all the time. i didnt even see one for a year and a half- i was so happy. Until recently. I heard someone new moved in on my floor and now i see at least one a day. mainly in the kitchen or bathroom. this morning i opened my linen closet and was greeted by one on the door. I'm terrified and soooo not looking to coming home at night :( when my boyfriend is here, it doesn't scare me as much, but when he's gone, and i know that it's me alone against them...i freak out. I even sleep with my bedroom light on now! And this morn i woke up, crept into the kitchen, and saw a tiny baby one on the counter, then, killed it, flushed it, then like 5 mins later, i saw another baby one! I was like huh? So i looked under my toaster, and ewwww...a dead roach with 2 more lil babies alive and well around it! I killed the babies and flushed the dead one, then later when i came in from work, i battled about 8 more lil babies! So i took the toaster into the bathroom and shook it out into the toilet, and i saw....a roach egg casing. threw away the toaster immediately!!

My question is: Particularly in regards to this baiting system, If you see one running, is it better to let it get away or kill it? I allllways kill them first by spraying it with Shout - yes, the stain fighter, it works, lol! and then i pick up the dead roach with a huge wad of paper towel (i dont want to feel it..ewww). I ccan't fathom the idea that one will get away and breed an then will come many more.
Sorry this is such a long post, but i had to vent. And it's great to know that i'm nt the only one with a SERIOUS FEAR of these disgusting creatures! I just want to be comfy in my lil one bedroom apt because i don't have the option of packing up and leaving :-(
Ninzerbean (author) in reply to platinumluvOct 7, 2010. 3:47 AM
Well I don't have experience in apartments but there is something about not seeing any roaches in my house until about two years after the treatment that makes me think they put out some signal or sign that says to other roaches "don't go there", they really are big colony bugs. So to answer you question about killing them... I don't know, mainly I don't know because like you, killing them is so creepy, in my whole life I have only killed two and both were to protect my son (in my mind, not like he was going to get eaten or anything) and the bravest thing I have ever done except have eye surgery so as not to have to wear glasses (stupidest thing I ever did). I guess in the end it is important to kill them, but once you bait your apartment you won't have them to even kill. That was sad about your toaster, try not to think about it. Yes boric acid powder will kill them if they run across it but more importantly make up the bait so they will eat it and bring it back to their colony. This is just foolproof. It really works. Thanks for writing, you are going to be OK.

wrestler285 says: Sep 9, 2010. 1:05 AM
ok i recently applied this a few weeks ago. since then i've noticed that the number of roaches i see has increased. my brother told me this might be cause they are being agitated by the poison. if this is true please let me know.
Ninzerbean (author) in reply to wrestler285Sep 9, 2010. 3:45 AM
It's a thought but I have never seen or heard of that happening - and it should not happen. There may be a few things to explain it though - first of all did you do everything I suggest in the instructions? I mean did you apply it in all the places I suggest? That is important, and it does take a long time to do - the switch plates on all your electrical outlets being taken off and put back on, behind each drawer in your kitchen, near water pipes, up high (door molding). Secondly, do you live in an apartment where there might be another infestation near by that is out of control? There must be some variable that is giving you this unsatisfactory result. The only roaches you should be seeing are dead ones and that is only in the first week. After that there just won't be any to see.

I promise you, if you do this right you will not have roaches, promise. Please get back to me and let me know if you have followed the directions really well or just sort of, and also where do you live, state or country.

Just as an antidote, a friend of mine here in South Florida who left his sliding glass doors open to the outside all the time had an exterminator every month but still had roaches, it took him two weeks to finish his whole house with my recipe, he only did half his house the first time and was still seeing roaches, I told him he had to do the WHOLE house and then, after he did - no more roaches! He let his exterminator go.

Hey nice ible! I don't have roaches here (mostly too cold) but what we do have is ant invasions every summer. I was shown the boric acid by a friend but I didn't want the powder blowing around my house so I mixed it in a plastic container with water and sugar to attract the ants. Soon there was a river of ants going to the poison! Then there was a river of "drunk" ants then there weren't any at all! I think your formulation could work similarly for ants.

Hey - I'm thinking about doing this in my apartment to cut down on having to do potentially illegal messing-with-things-you-don't-own (aka, I don't know if I can actually open up light switches and things). Where did you put this bowl of death?
EmmettO in reply to jesuisraviSep 7, 2010. 6:52 PM
We put it where we see ants. I imagine the same would apply to roaches

Really great idea to make a paste. I never thought of that. :( Good pix, too. I discussed a roach problem I had with an entomologist (someone who studies bugs), and he told me that roaches and mice (for two) can't belch. They get the boric acid inside them, get gas, and explode. They have no choice but to die. He further told me that roach eggs can take as long as six months to hatch, so don't think it's not working just because you see a few babies for 3 or 4 months. They will also die quickly.

gingerchew says: Aug 3, 2010. 4:52 PM
I just did this to my little one-bedroom apartment... it only took an hour and a half, start to finish. I have two questions: 1. Do you think it will really work in an apartment? In my case, there is one other above-ground apt and a basement apt (& both residents said they'd never seen roaches - I moved in a month ago and only saw one the other night, and again the next night, and it could have been the same one for all I know). 2. How long do you think it will take before they are totally gone? I have a definite phobia of the suckers - the first one I found was on my BED, and the second was on my bedside table! THANK you for this superb article!
Ninzerbean (author) in reply to gingerchewAug 3, 2010. 5:15 PM
I think that if you have more than the one you saw - and I think it may have been the same one twice, that it will be gone in less than 3 days. I honestly don't know if it will work in an apartment because I have no first hand experience of that situation. Your neighbors may or may not be telling the truth, but from my experience in my own house it seemed that the roaches communicated with each other (don't laugh) and sent out the word that my house was no good to be in. I don't know how else to explain the fact that I was not seeing dead ones for 2 years. Read through all the great comments for extra help and hints, the combined knowledge of so many of us is a super resource. You are going to be fine, I promise. It does take a long time to do it right, an hour and a half is right, people don't believe it takes so long to do a house.
gingerchew in reply to NinzerbeanAug 15, 2010. 4:21 PM
It has worked! I was sleeping here again within days of baiting. I'm sure that the roaches do spread the word... and thank god! I think I'll just do it again in 6 months to a year (since it's an apartment) if I haven't moved. Thank you again, so much!
Ninzerbean (author) in reply to gingerchewAug 15, 2010. 8:05 PM
I was thinking of you today as I was re-doing my own house and wondering how you had made out. I figured after 2 years it was time and I had seen two dead one's in the last month. But I don't even want to see dead ones. I should be fine now for about a year for sure. Isn't it a relief? Glad to have helped.
gutzybroad says: Aug 4, 2010. 1:53 PM
Thank you for your artical. I had all of the products in my house already. I had the boric acid already for the roach problem but I have pets and grandchildren who visit regularly so I only could put it in a few places. I live in florida and the infestation is horrible in the home we bought. I was seriously thinking about tenting the house but the cost is outragious. Im going to try this first. I will repost with results. wish me luck thanks again
Ninzerbean (author) in reply to gutzybroadAug 10, 2010. 4:59 AM
Good luck, you will be fine, but I warn you that you have to be prepared for hours of work. Taking off all the switch plates... pulling out the kitchen drawers. But you won't have to do it again for at least a year, maybe more.
CherylTX says: Jul 2, 2010. 3:09 PM
Thank you thank you for posting this! I was so sick of seeing those giant roaches (water bugs, whatever) crawling on the outside of my house when we come home at night, and dodging them on the front porch. I mixed up your concoction. The boric acid I found was 100% so had no blue in it and the mixture wound up looking like cookie dough. Put it in all the recommended places inside the house, even though inside hasn't been a problem I figure it's just a matter of time. Started on the outside of the house and when I was done and came back to the front porch, found a giant roach already chowing down on the Cookie Dough Of Death. In broad daylight! It must be irresistable! Two days later there are giant roach bodies scattered around near the house but NO live roaches crawling on the siding anymore! Woohoo! Thanks again!
Ninzerbean (author) in reply to CherylTXJul 19, 2010. 4:43 AM
That is so funny! Anyway, I am so glad to have helped you, I found two dead ones in the house last week so after two years I guess it's time for another application of the Cookie Dough of Death. Thanks for your feedback.

This is amazing! I bug bombed our house once, and it worked. However, i really hate the idea of filling my house with a toxic cloud of poisons. This is perfect for me! I am more afraid of roaches than I am of poisonous snakes. It will be a relief to be free of them. Thank you!
Ninzerbean (author) in reply to electrikitten28Jul 16, 2010. 4:57 AM
I wish I could go into business with this but it would mean I would have to go into houses that had roaches - I just would freak. It takes hours and hours to really do your house right, but it sure works.
shortw says: Jul 10, 2010. 12:07 AM
Lowes hardware used to sell a bait that had the consistency of peanut butter , but it came in a stiringe . It worked wonders for many years to come. But they discontinued it years ago, I guess it worked to good and they could not make enough money by selling there other poisons.

under_roach_attack says: Jun 29, 2010. 1:39 AM
As i type this i am at day 4 of the man against roach war that has be declared in my home. First i bought some pet friendly organic bug dust, but it seem like it was not working or taking to long to work, or maybe i'm just getting tired of seeing the enemy. So i did the boric acid mix, only that in my mix i added alittle water, nothing major just enough to help make it pasty. I wanted to know would that affect the killing affect? My next tool of death that i plan to use is chinese chalk, which is illegal but is suppose to be a one hitter quiter for roachs. I'm open for all advice on the matter.
Ninzerbean (author) in reply to under_roach_attackJun 29, 2010. 3:50 AM
I don't think water will matter if you added it to the kayro syrup or honey or maple syrup, but if you just added it to the boric acid itself it won't so any good. The sweet stuff is the bait, the poison is in the bait. Read all the comments posted here and see if you can find some tips. But really this is going to work. It is now almost July 2010 and when I posted this ible last year it had been about 10 months and so here we are a year and 10 months later and I have still not seen a roach. I did a touch up when I did the 'ible but that was it.

razz1969 says: Jun 28, 2010. 11:36 PM
I also have a severe infestation that I inherited from the previous tenets. It took a whole 5 minutes to make and about an hour and a half "feeding" the roaches. "Feeding" you say, that's right by the time I was finished spreading the bait the roaches was feeding on it by the masses. Only time will tell. If you have a crawl space and or an attic you can use a leaf blower to propagate the boric acid and that should stop any future re-infestations. You can also do the same on you yard to kill fleas. But please use a respirator not dust mask, and on a still dry day.
Clemtasm says: Jun 27, 2010. 1:42 PM
I noticed your comment about keeping boric acid out of your eyes. Interestingly enough, it's a common ingredient in eye drops: http://answers.yahoo.com/question/index?qid=20080515090341AACNhbn (first to pop up in google search)
Ninzerbean (author) in reply to ClemtasmJun 28, 2010. 5:15 AM
Yep, if you read all the comments you will find some information that Goodheart wrote about that subject. I was just writing what the back of the container said. I am reading a great book called "The Poisoner's Handbook" and you would not believe how many things like arsenic and cyanide used to be used in regular household goods in the 1920's. It's an amazing look at the ways and whys of forensic medicine working with the police to solve what had been unsolvable murders and simple accidents.

I had a severe problem when taking down an attached utility room to rebuild. We are talking Atila the Hun war of roaches behind a sheet of old ply-wood. We were armed with magazines, spray, a lot of EEEEKKKSSS!! AAAAhHHHss and so fourths battling the now lift off kamikaze dive bombers. We had hit the mother load nest. Talk about freaking out. Me and my friend both tweaked our backs and sprained our ankles to save our own lives. As the author states "low and behold the internet to the rescue". I originally found the borax/sugar mixture. It did work wonders on those escapees that managed to fly up into the roof space and when they came to cannibalized their own squashed mates, that we borsugar dusted they got a lethal tasty treat. But now I am going to try this sticky concoction to further lure the enemy into a trap and hopefully win completely without the dusty mess. However, borax sucked up in the vacuum will kill fleas that may hatch in there if you have pets. thanks for the recipe and your story. Love the pics.
Ninzerbean (author) in reply to olulpanaJun 25, 2010. 7:52 PM

sam12587 says: Jun 11, 2010. 1:30 PM
Good instructable. I got a house with the same issue. I had to gut the bathroom and the plumber had me sprinkle borax all over the space & walls the tub & shower would occupy. Then after he'd installed the new pipes & tub/shower surround he told me to put borax in all the walls as I dry walled the room & to wear a mask so I wouldn't breathe it in . I did. I haven't seen one bug inside since. I have seen them outside but not in my house. I didn't even mix it with sugar and they still eat it and since it's in the walls my family is safe. This is the same chemical put in ant traps & some roach traps. I also use borax to make organic laundry soap - not sure what "yuvaliat" is concerned about. My understanding of this chemical is that it's only toxic to mammals if breathed in or if eaten by the pound (yuck). great instructable - I never could figure out how it could be stuck to stuff. If my walls fail me then I'll definitely be doing this.
Ninzerbean (author) in reply to sam12587Jun 11, 2010. 2:27 PM
There has been a lot of comments here about the differences between borax and boric acid which is not the same thing, I am glad you don't have bugs and that is what is important.

CrystalDyes says: Jun 10, 2010. 5:45 PM
As a lifelong resident of Florida, I've seen every kind of roach known to mankind over the last 60 yrs. One of the things that has significantly reduced the infestations for everyone is the change from paper grocery bags to plastic. We all saved our bags to put in the garbage cans. What we didn't know is that roaches loved the brown paper and the glue so every week that we brought home more bags, we re-infested our homes. I've learned that eliminating the bags as well as any cellulose food packages (storing stuff in plastic containers) has allowed me to live without an exterminator for over 40 yrs. Still get an occasional palmetto bug coming in from outside but no German cabinet roaches.
AustynSN says: Jun 10, 2010. 12:44 PM
I've been using a VERY similar formula for the ant problem we have in our home. (We've seen a couple roaches, but it's not too bad yet. Though I still plan on going on the offensive against them once I'm sure the ants are gone.) With my formula, it was 2 parts each peanut butter and powdered sugar with 1 part or less boric acid. With the ants, you have to start small on the poison and slowly add a little more every now and then. The goal isn't to kill the ants, but the queen. They keep taking the poisoned food to her. If the poison is too weak, she doesn't die. If it's too strong, they die before they get it to her. There are now very few ants to be found in my kitchen. With about 20,000 species of ants, there's now way to know how much poison it takes to kill any one particular queen so it's trial and error.

PurpleQueen says: Jun 8, 2010. 1:06 PM
Boric acid can be purchased inexpensively (including shipping) on-line. We got a HUGE bag of it and shared it and expenses with friends and neighbors. Thanks for this posting. P.S. We use boric acid around the outside of the house (between the grass and the foundation) and under the lip of the entry to our lanai here in Florida. Keeps lots of critters from coming in. Ants get it on and in them and take it back to the nest! I assume this is true of other little nesting buggers we have. Doesn't work for dog ticks, tho, unfortunately.
Ninzerbean (author) in reply to PurpleQueenJun 9, 2010. 3:07 AM
What about when it rains, does that matter? The reason I did not want to use the powder in my house is because I vacuum a lot and with the paste I could put it more places. I swear this is so effective I would like to start a business (putting the paste around their homes) telling people they don't have to pay me for a year and only then if they have not seen any roaches.
PurpleQueen in reply to NinzerbeanJun 9, 2010. 6:53 AM
The rain seems to turn it into a kind of paste up against the cement...in Florida so many homes are cement block with stucco, like ours. And, it soaks in a bit, which offends their delicate nature. lol I had friends take me out to dinner at a very nice restaurant and then out dancing because they had paid for bug removal.....lots of money......still had the bugs.....but this works!
ObscureProtection says: Jun 6, 2010. 12:56 AM
I'm currently dealing with a roach infestation myself and I'm sooooooooo grossed out by these buggers. Do you think it's possible to store this formula in an empty syringe for future use? Or do you think it will just dry out? THANKS! I can't wait to try this out!
Ninzerbean (author) in reply to ObscureProtectionJun 6, 2010. 5:16 AM
Maybe in the fridge in a zip lock baggie, or the freezer. A syringe is too small, you need to mix up about a cup to two. It is too thick to be applied with a syringe anyway, a popsicle stick is best.
SMARTARSENAL says: Jun 5, 2010. 7:36 AM
Worked like a charm!! And had some matchbox covers lying around, so also placed some inside the tubes and made my own "motels", was then able to place a few on counter tops behind blender etc.
Ninzerbean (author) in reply to SMARTARSENALJun 5, 2010. 7:53 AM
Excellent! Be sure to pull your kitchen drawers out so you can smear some bait on the back of them.
artquilter says: Jun 2, 2010. 2:21 PM
I don't have much knowledge of roaches, having only seen one in my life, but thinking more of any bugs life, even if the adults die, if they lay eggs somewhere, those would be the 2nd round.  So how bombing once would work is beyond me...I'd think this method would continue to work because the bait is sort of permanent...there would always be a little of it somewhere to continue working on other generations of roaches.

Has the author of this instructable gone back to see if bait is diminishing?
Ninzerbean (author) in reply to artquilterJun 2, 2010. 2:57 PM
The bait is now rock hard but really has not diminished to my eye. I still have not seen a roach - dead or alive. It's been a long time, I think close to 2 years now. I probably should mix up some fresh bait and do it again just to be safe. It will most likely take seeing a roach for me to do that though. 
margann says: Apr 29, 2010. 11:07 AM
I once came home to thousands of them in my apartment. Truly an experience I'll never forget. Come to find out, the apartments around me had bug bombed while I was gone. I filled every crack and crevice in my home with steel wool. If I couldn't or shouldn't (think electrical outlet)  put steel wool in, I sprinkled boric acid. Both scratch their carapace and kills them. For a while I would come out and sweep up the dead with more glee than a nice person like me should have. It was a big job, but 2 years later I was still roach free and my wall neighbors were not.

CraftyLuna says: Mar 14, 2010. 7:25 AM
So it's been two days, no noticeable difference yet. I found a bug identification website and found out I have German cockroaches, which are the most insidious kind.  The recommendation on that site is to move. :( 

Perhaps this will just take more time, or perhaps I need to put out more bait. Or maybe I need a stronger mixture?
Ninzerbean (author) in reply to CraftyLunaMar 14, 2010. 8:08 AM
 Hmmmm, you have to try to get rid of the roaches you see too, go look at littlewolf's comments, his mom would find the nests (ugh) and that seems to help, I didn't have that problem, give it another day CL, I have tremendous confidence in this stuff.
CraftyLuna in reply to NinzerbeanMar 14, 2010. 8:38 AM
Eek! Ok, I know they are in the workings of the oven, but I don't know how to take apart an OVEN to get in there!  I did bait behind the oven and turned on the self-cleaning cycle and I saw a bunch of the little ones come out, so I was hoping they went for the bait. Maybe we just have SO many (and we do, major infestation) that it will take more time for them all to try the bait. Most of the ones I'm seeing are babies, perhaps they just hatched and haven't found the bait yet.  I will give it more time, but I'm starting to think we'll have to leave for a weekend and fumigate.
Ninzerbean (author) in reply to CraftyLunaMar 14, 2010. 8:49 AM
 Your vacuum may become your new best friend. You may have to keep it out for a week straight. It does sound like you have a terrible problem but I know this will work, but you must get rid of the live ones you see as it will help a lot. Keep me posted. I don't think you need to take the oven apart but take out the tray at the bottom if you can, the one that holds pots and pans if you have that kind. 
CraftyLuna in reply to NinzerbeanMar 14, 2010. 9:14 AM
Hmm, don't have that tray at the bottom.  Grossest thing ever: I see them crawl across under the plastic where the display is, right across the numbers. (ew ew ew) I'll see if my boyfriend can help me get the top part off.

By "get rid of the live ones" do you mean spray them?  I have spray but I hate it because it's so toxic.
Ninzerbean (author) in reply to CraftyLunaMar 14, 2010. 9:18 AM
 No, I'd never spray either, I mean vacuum. Your boyfriend is a saint.  Tell him so. Don't cook him dinner though. I mean with that oven.
macgeek says: Mar 12, 2010. 5:26 PM

CraftyLuna says: Mar 12, 2010. 11:21 AM
i just mixed up the stuff and put it all over my house, in all the places you said.  This old Atlanta house has at least FOUR different species of roaches that I've seen, and every night if you want to get a drink of water from the kitchen they are ALL OVER the counters, so I really hope this works. Those electronic sonic pulse things that you plug into the walls?  Such a joke. The roaches were actually nesting behind them. 
Ninzerbean (author) in reply to CraftyLunaMar 12, 2010. 12:51 PM
 Yes, it really works, you are going to love getting up in the night and not seeing roaches, I know I do. I got one of those sonic things for rats that were living in my ceiling and I have to tell you that they really work for rats, I had no more after the first night I plugged it in, then a year later I found evidence of rats in my loft in the garage so I got another and now I have no rats there either. Just thought I'd tell you in case...
elias.alberto says: Jan 21, 2010. 9:04 PM
 My dad has been using boric acid powder, which he used to buy in any drugstore, to make a recipe to kill roaches. But the recipe he has been using for ages is 50% boric acid, 50% wheat flour, and a variable amount of grated ONION (about one onion for each 1kg of recipe). It seems those roaches will eat we usually eat, so you can mix anything edible to the recipe and they will eat it.
Ninzerbean (author) in reply to elias.albertoJan 22, 2010. 4:30 AM

Ninzerbean (author) in reply to stripedstarfishJan 4, 2010. 3:05 PM
It's going to work, but let me know anyway. I LOVE being roach free. But, wait, can't you just add more boric acid powder to un-sticky it?
Transquesta says: Jul 27, 2009. 9:57 AM
Thanks for the great instructable. Yeah, living in the southern U.S. I've known about Roach Prufe/boric acid for a while, but it doesn't help to remind people from time to time. Then, too, unless you want to spend a whole LOT of extra money, you don't necessarily have to buy this specific brand. Any old generic form of boric acid/corn starch mix will do. Speaking of which, you really don't have to form it into a paste unless you want to put it into locations where you can't use the powder/'dust.' Be aware that most of the boric acid variants of 'roach powder' contain some kind of 'bait' in the mix off-the-shelf: flour, sugar, corn starch or similar. Be also aware that A) you're not the only one who is terrified of cockroaches (it's the 'Palmetto bug' variety which sends chills down my spine), B) this isn't the only instance of the pesticide industry trying to kill what works (think Chlordane), and C) roaches--especially--will be a RECURRING problem regardless of how much food/water you leave out. Roaches come in via grocery bags, boxes, etc. mainly because the glue that holds such items together drives them mad. It's like cockroach catnip.
citizen251 in reply to TransquestaDec 15, 2009. 3:04 PM
Here in the Southwest (Tucson) we have something similar. It's called a Palo Verde Beetle and can actually break the skin when it bites you. My friend once saw one crawling in my house. He screamed like a little girl and squealed, "It's sentient!" To this day I don't know why that was the first thing to come to his mind. Did I mention they fly? They fricking fly!

Good Gawd, Man!  That skeester's big enough to ride!  It looks like one of those things from the movie Damnation Alley.


. . . I'm sorry, just call me a p*ssy and be done with it, but if I saw anything like that in MY house I'm pretty sure II'd have to move.  (FWIW, I used to live in Tucson 'back in the day,' and I never saw anything like that.  'Bout the only creature of note were hovalinas, and the only thing I remember about them was that they were fast.  They looked like little jets moving across the mesa.)

Here in Florida we deal almost exclusively with palmetto bugs but they are just giant roaches. Once I found one in my car - after I had parked it (or I WOULD have had a wreck) and I had to call my mom to come get me so we could switch cars.
Transquesta in reply to NinzerbeanJul 28, 2009. 11:24 AM
Try waking up one night with one of those 'palmetto bugs' staring up at you as he's sitting on your chest. :-) In southern GA where I was living at the time, they grew big enough to ride!

Ninzerbean (author) in reply to clonerNov 9, 2009. 1:38 AM
 Yeah, that may be tough. I was sure every country has Boric acid powder though,  it is so common, obviously I am wrong, maybe someone can send it to you.

tmross4 says: Oct 10, 2009. 4:08 PM
If you mix honey and boric acid into a paste, it's good for all the ants that like sweet stuff. I put some on a plastic coffee can lid and then placed another, slightly smaller lid that I pucned some small holes into, on top to give a tight fit, then hung the whole thing right in the middle of an ant trail on the outside of my house (high enough so kids and pets could get to it), and within a week, no more ants!
canida says: Oct 9, 2009. 2:16 PM
Awesome.  Our new digs are directly over several restaurants, so after a coupld of sightings we're about to go on roach patrol here at Instructables HQ!  We'll try your technique, and report back.
Ninzerbean (author) in reply to canidaOct 9, 2009. 2:25 PM
Well at least you know not to eat at those restaurants! But you will solve their problem as well. It's so funny that your very own site will have the answer to a problem. Please report back. 
kimiga says: Aug 25, 2009. 6:07 PM
Thanks for the great instructable. I am actually in the middle of baiting my house with two cups boric acid 1 cup flour and 1 cup maple syrup/a couple table spoons of honey. The consistency I'm getting is more like playdough than peanut butter though. Is this fine or should I add water/more honey( i ran out of syrup) to make it softer? I was also thinking of applying it on the outside of my house near any entrances, but I don't know if that will attract more pests into my house or not. Suggestions? I'll update after a week, the problem is mainly in my kitchen. We see and kill one big roach almost every night, and its getting very distressing. Conventional baits have not been working for us. Here's hoping for the best.
spikez in reply to kimigaSep 8, 2009. 8:44 PM
i've been building a roach problem steadily for the past 3 yrs from lack of care in the nights prior to crashing It's become a big problem and was seeing them continually during the day. initially we tried the boric acid dry powder & sugar mixture in little cups around the ktichen and in warm places in the house (tv, computer, etc) Slight effect but the suckers would walk thru the powder with no effect (i hope they eventually died a painful poisonous death). Tried the goop mixture but mine turned out more like play dough as i had to substitute sugar/water instead of maple syrup. Now the problem has decreased but i see the little ones regularly and if i turn on the oven the whole tribe emerges. So i know they hide out in the oven but i can't bait in there and i've baited pretty much everywhere else. What else can i do? More goop? Maple syrup goop? Put the bait in the oven and take it out when i have you use it? Plus i'm pregnant so i'm scared of touching the stuff so i make my husband touch it.
Ninzerbean (author) in reply to spikezSep 9, 2009. 1:28 AM
Well if you read what LittleWolf writes it seems that he had the same problems as a kid. I do think you need to mix up stuff the right way and try again. Get rid of those little cups because they don't mix with babies. You want to bait inside the oven - but not where you cook, in the guts of the oven. This is a common place for them to live. A vacuum will really help here. You want to be trying to find and destroy the egg cases. Kayro syrup is cheap and good, cheap pancake syrup is the same stuff with color. Maple syrup is expensive and not necessary really (it's all I had on photo day). Remember inside your walls. Go on a vacuuming kick where you vacuum every day for a 2 week stretch. This is going to get better and fast. Really. Just take a deep breath and start over from square one with the goop.
spikez in reply to NinzerbeanSep 30, 2009. 6:35 PM
mixed up new goop with honey this time as we don't have pancake syrup available here. it's much softer than the old goop so i'm hoping it will make a difference with summer coming up. I baited using the Little Wolf tracking method need the gap between my kitchen bench and cabinets (lots of poop there). A week in there isn't a marked difference. How long did it take to empty your kitchen?
Ninzerbean (author) in reply to spikezOct 1, 2009. 4:32 AM
I saw a difference right away, I went from seeing a roach every week to only one dead on in 10 months. There were more around than once a week but you have to understand how terrified I am of them, I didn't go looking for them. I think what you have to do in your case is follow LittleWolf's mom's procedure in that you have to clean out the nests of live ones in your home before you bait. In your case I would use vacuum and use that boric acid powder as a thing to put down on the ally-ways you are seeing poop. Next day vacuum, next day you should see no roaches - re read LittleWolf's stuff, they found nests in the TV and all sorts of places. It was Mexico, it sounded like a never ending war. But Spikez, this works, it will work, you may have to do a bit more work than I had to but you will be roach free. Don't forget to bait inside your walls, and especially around water - pipes, toilets etc. Let me know.
spikez in reply to NinzerbeanOct 1, 2009. 11:10 PM
thanks for the advice, i don't have any poop around the pipes but i've baited pretty much everywhere. I've noticed since the 1st goop baiting that the roaches have disappeared from the Coffee water tank but i still see the little guys regularly and the big ones when the oven is turned on.
spikez in reply to NinzerbeanSep 9, 2009. 4:58 PM
thanks for the advice, i'll try vacuuming the oven. i have brick walls so i don't think they can get in there?
kimiga in reply to kimigaSep 5, 2009. 3:42 PM
It's been about two weeks and I have very good news. We don't see the adult sized roaches in the house anymore. There was one found in our living room(where we've never seen roaches before) but we baited that room immediately after killing it and have not seen anything since. In our kitchen where most of the activity occurred we did see a couple of tiny roaches, smaller than a pill, but they were either dead or not feeling too well because they didn't scurry away at all. We also moved the rags and soap dish off the sink counter during the evening, and have not seen anything since. Thanks again, this has been so effective. I've told my friend who recently moved into an apartment, and even though he has not seen or heard of any roach complaints, he is going to bait his whole apartment with the stuff, just in case.
Ninzerbean (author) in reply to kimigaSep 5, 2009. 8:46 PM
Fantastic. Thanks for letting us know, it is so instant grat that it's like there must be another answer but it's the bait. Living without roaches is in your power and not the pest (not)control company's any more. Power = yum.
Ninzerbean (author) in reply to kimigaAug 26, 2009. 1:47 AM
It's going to turn rock solid when it sets up so yep, add a bit of water or syrup or what have you to make it a bit more like peanut butter just so it is easier to put around. This will work I promise.
kimiga in reply to NinzerbeanAug 26, 2009. 3:40 AM
Do the roaches still go for the bait after it sets rock solid?
Ninzerbean (author) in reply to kimigaAug 26, 2009. 5:25 AM
I'm sure they do - it's just impossible to spread around on the pipes etc. If they didn't still go for it there would be roaches again right away. I think there is a hidden roach language where they talk to each other and say "stay away from that house, they have really bad food" or something to that effect.
aaronanalog says: Oct 1, 2009. 8:05 AM
Ok, well I tried everything else and nothing works. I just got a portable dishwasher and after washing my dishes they were inside the dishwasher ! YUCK !!! We have been eating fast food for over a week now because we do not want to use anything in out apt. I have no idea where so many came from so fast. So I mixed up this stuff and applied it everywhere there is a trace of water or a hidey hole for those nasty things. I will repost again in a few days with the results :-)

No, the people downstairs moved out and now that I think about it they had packages delivered every day so maybe that was the source. I love this idea of the paste though. I mixed 3 parts boric acid to 1 part flour and pancake syrup. I hope it works.

FWIW, the manufacturer of 20 Mule Team Borax says that their product is 99.5% percent straight borax... I haven't tried this approach, yet. Darn sure going to try, though... the apartment complex where I live is seriously infested with them
Ninzerbean (author) in reply to slanderAug 3, 2009. 9:14 AM
But Slander, it's not the same stuff - you have to get boric acid not borax.
cloner in reply to NinzerbeanSep 16, 2009. 1:25 AM
Borax, also known as sodium borate, sodium tetraborate, or disodium tetraborate, is an important boron compound, a mineral, and a salt of boric acid. It is usually a white powder consisting of soft colorless crystals that dissolve easily in water. Boric acid, also called boracic acid or orthoboric acid or Acidum Boricum, is a weak acid often used as an antiseptic, insecticide, flame retardant, in nuclear power plants to control the fission rate of uranium, and as a precursor of other chemical compounds. It exists in the form of colorless crystals or a white powder and dissolves in water. It has the chemical formula H3BO3, sometimes written B(OH)3. When occurring as a mineral, it is called sassolite. Borax is more common in groceries here in the philippines than boric acid.
Grimarr in reply to clonerSep 16, 2009. 1:08 PM
Yeah, I was being dumb and not getting my facts straight before I said anything.
Ninzerbean (author) in reply to GrimarrJul 31, 2009. 6:44 AM
It's not the same thing - I checked. Anyway Boric acid is only a few dollars when you can find it by itself. Roach Prufe is around $7 USD and would last you years. And years.

Ninzerbean (author) in reply to LilithAvalonSep 5, 2009. 1:28 PM
It is so disturbing to think of your pets eating roaches that I just don't know what to say, of course it may harm them but I think it's more important not to have roaches around for them to eat in the first place - this can only be a win win situation as you don't know where those roaches (poisoned or not by you) may have been before being in your rat's mouth. It's just best not to have roaches around - poisoned or not. And yes, I know rats eat roaches. So do possums, I love possums just for that reason.
hannahruth0 says: Aug 25, 2009. 7:09 PM
Thanks for the super funny, well-written ible! I picked up plain boric acid at the local drug store, used pancake syrup from Walmart, and used whole wheat flour I had. Total cost = $10. Hopefully the roaches like it. I gobbed it all kinds of places.

Dear Liat, I know how you feel. Been there. I don't know if mice will die as it's not a very toxic poison to animals but I'm sure they will eat it. Have you tried rat poison? Let me know how you fare - it works so wonderfully fast.
yuvaliat in reply to NinzerbeanAug 13, 2009. 4:54 AM
Well, now I'm not sure what to do I read a lot about boric acid since yesterday and it seems to be quite toxic, see for example:
http://www.pesticide.org/boricacid.pdf

We're growing organic vegetables (just for ourselves), so we don't want to use toxic things.

Thanks,
Liat.
Ninzerbean (author) in reply to yuvaliatAug 13, 2009. 5:43 AM
That's a great article but I don't understand your concern as it confirms my instructions on how best to use it - out of possible reach of humans and pets. The article is clear that of all pesticides type things it is "the least toxic" - not to bugs of course, but to humans. I don't know how putting the bait inside your walls and behind kitchen drawers will affect your organic garden. I personally don't advocate using the powder alone - that is not in my 'ible. The point is that by making it a paste you have the ability to place it in areas powder wont go, and it won't be vacuumed up as a powder would. Do what you think is best for your situation. I really care about not being exposed to toxic chemicals.

TwinFlower in reply to CreativemanAug 3, 2009. 10:38 AM
When I was looking into using this for ants I did see that it should work for termites too. Here is an article that talks about making bait traps for termites: http://www.termite-1.com/Cost-Of-Tenting-For-Termites/Does-Boric-Acid-Kill-Termites.php
I read another article that suggested a mixture of Boric acid & propylene glycol. The probylene glycol should help the boric acid penetrate the wood and will also provide some protection from future termites invading.
Good Luck Creativeman.

Ninzerbean (author) in reply to CreativemanAug 1, 2009. 3:18 AM
Hey Cman, sorry I missed your question. I don't think this would work for termites. They eat wood - unless you mixed up sawdust in the mix..... really. That is an idea... I know when companies termite proof your home they drill holes all around it - every 12 -18 inches and inject a poison that acts as a barrier. I don't know if that works either though.
Goodhart in reply to CreativemanJul 26, 2009. 3:11 PM
If you can get them to walk through the dry powder, it would. Any insect has an exoskeleton and they are easily dissolved by boric acid.....the problem is getting it to them in a sufficient quantity to be effective. I have used one part 10x sugar mixed with 9 parts Boric acid powder for ants.....

unclesam says: Aug 4, 2009. 1:00 PM
Ninzerbean, comment re: toxicity of boric acid. There is another product that can be used to kill roaches, fresh-water diatomaceous earth, which is sold as a powder at garden centers. It kills by causing bugs to ooze to death, by strictly mechanical means, but it is not toxic in the chemical sense. A human or pet could eat handfuls without real harm, though it should not be inhaled. It must be FRESH-WATER diatomaceous earth, NOT the more common salt-water type sold for use in swimming pool filters. Diatomaceous earth is mined from ancient defunct lake beds and consists of the crushed shells of long-dead diatoms, microscopic water creatures. At the microscopic level, the crushed shells appear like tiny glass shards, and they work into the soft joints between an insect's shell, cause their insides to leak outside. This product should be provided dry, around whatever is used as bait, or just along baseboards, behind appliances and cupboards, places where it will not likely be just vaccuumed away in the course of housecleaning. It will remain effective for as long as it is left in place. Unclesam
Ninzerbean (author) in reply to unclesamAug 4, 2009. 1:31 PM
Thank you for your info about diatomaceous earth BUT it's not what I'm trying to get across here - you can't do with it what you can with boric acid as an INGREDIENT in bait so that roaches eat it and bring it back to the colony, AND, you can put the bait the 'ible is about in all sorts of places you can't put powders. There are tons of things that kill roaches and some great ones such as your suggestion but they don't work the same way and you can't use them the same way - behind outlet covers, stuck to water pipes under sinks, on top or door jams, behind pictures. I think after 80 something comments on the toxicity of boric acid we have established beyond a doubt that if used with common sense it is not a problem.
Ivriniel says: Aug 3, 2009. 7:57 PM
Um, roaches aren't social insects so they don't form colonies.
Ninzerbean (author) in reply to IvrinielAug 4, 2009. 4:37 AM
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.
Ninzerbean (author) in reply to IvrinielAug 4, 2009. 4:06 AM
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.

Ninzerbean (author) in reply to clonerAug 3, 2009. 9:18 AM
I think you could find a lot of places outside that would be free of getting rained on and I think that is what you should do with your left-over bait after you do the house. I put a lot in my garage too 'cause that is where my laundry is.
ClareBS says: Aug 2, 2009. 7:29 PM
Great instructable. About 35 years ago when I was a student and lived in old inner city housing I discovered boric acid. All I did was sprinkle it along the cracks between the walls and floors. The roaches would walk in it then carry it on their feet back to their lair and their friends and family would groom the roach with dirty feet and, voila, they all died. I didn't have to worry about pets at the time so I didn't have to hide it. And thankfully, they don't live where I do now.
kevvv says: Jul 26, 2009. 12:48 PM
So exactly how toxic is this
mash4077 in reply to kevvvAug 2, 2009. 6:19 PM
boric acid is minimil toxicity to humans look it up it is very common
Eye Poker in reply to kevvvJul 29, 2009. 6:23 PM
The toxic effect on the roaches is that it desolves their exoskeleton.... Not an issue for exposure to you.....unless you have an exoskeleton?!?
Tyler W. Cox in reply to Eye PokerAug 2, 2009. 2:27 PM
Boric acid kills insects in two ways. First, as a poison. Second, by abrasion. Boric acid slices into an insects exoskeleton and creates tiny openings that cause the insect to dehydrate and die. Roughly speaking, crawling through boric acid dust does the same sort of damage to an insect that crawling through glass shards would do to a human.

Ninzerbean (author) in reply to kevvvJul 26, 2009. 1:14 PM
Mike Potter, Extension Entomologist at the University of Kentucky College of Agriculture states that Boric acid is low in toxicity to people, pets and non target animals but very toxic to roaches. I added the comment below because that is what the canister says. It's best to play it safe always. What I really like it that it has no oder.
kevvv in reply to NinzerbeanJul 26, 2009. 6:17 PM

Ninzerbean (author) in reply to kevvvJul 27, 2009. 4:19 AM
After it is mixed with the syrup you can't inhale it, it's not dangerous anymore to you - except if you eat it or rub it into your eyes.
Goodhart in reply to NinzerbeanJul 31, 2009. 9:04 AM
Hmmm, inhaling syrup might not be the best thing to do either ;-)
Ninzerbean (author) in reply to kevvvJul 26, 2009. 1:02 PM
The boric acid powder is hazardous if it gets into your eyes, is inhaled or swallowed. It's alright to get it on your skin but why take chances. You must use a bit of common sense when mixing it up with the flour and syrup, I did it outside, I will make a note to that effect, thank you.
Goodhart in reply to NinzerbeanJul 26, 2009. 3:08 PM
A weak boric acid solution was once used as an eye wash, medically. It really is a LOW hazard chemical :-)

It works best when kept absolutely dry, and if you can get it powdered as finely as possible, so it statically clings to their shells. Then, these social insects can pass the fun amongst the clan efficiently :-)

Boric acid can be bought in the drug store as a powder, but sometimes it is not a very fine powder.
DebH57 in reply to GoodhartJul 31, 2009. 8:55 AM
I agree with Goodhart, when I worked in a hospital nursery we would make a solution of boric acid and sterile water to wash around the newborn babies eyes with. It is very safe for humans.
Ninzerbean (author) in reply to GoodhartJul 27, 2009. 4:24 AM
I have a central vac which is so strong it can suck up noisy children across the street, anyway that's why using the power didn't work for me. John kept sprinkling it around and besides looking terrible (while powder on a red tile floor) I would vacuum it up. That's amazing about it once being an eye wash.
Goodhart in reply to NinzerbeanJul 27, 2009. 5:50 AM
Although it is not recommended as an eye wash anymore, is is a mild antiseptic. It is not recommended that one breaths it in however.

Based on mammal median lethal dose (LD50) rating of 2,660 mg/kg body mass, boric acid is poisonous if taken internally or inhaled. However, it is generally considered to be not much more toxic than table salt, so can be safely used as a fire retardant. F. Jay Murray (2004). "Don’t Lose Sleep Over Borates and Mattresses".

Note: 2,600 mg / kg body mass is approximately 1/2 pound of boric acid for a 200 lb adult. Loosely speaking, 1/2 a pound of powdered boric acid is 1 cup (cooking measurement.) That's a lot of powder to accidentally ingest!
Goodhart in reply to Tyler W. CoxAug 2, 2009. 2:14 PM
yeah, and being an acid, even though weak, it would be awfully sour tasting...

The advice about sealing cracks to the outside is a good first step, but you forgot to mention the most important aspect of pest control. This should go in big bold letters in the first step:

Stop feeding and watering them!

Roaches do not magically enlarge and duplicate themselves. They are living creatures that need water and food. If you leave a bowls water and food outside, you are going to end up with a visiting cat, dog, raccoon, or possum. If you leave a bowl of water and food inside the house, you will end up with roaches or ants.

Granted, roaches may take weeks to dehydrate in a sufficiently humid environment. (Food-grade diatomaceous earth can speed this up greatly.) But they cannot survive and reproduce indefinitely when your house is bone dry.

Insecticide does have its place. Ocassionally you might accidentally leave dishes in the sink overnight, or overlook a puddle of water on the floor. Now and then, roaches will enter the house through cracks or on your shoes. But insecticide should only be used as a back-up method.
Ninzerbean (author) in reply to NobodyInParticularJul 27, 2009. 8:34 AM
I disagree with you - roaches can live for years on stuff we do not consider food - I think they can live for three years on nothing but nail clippings. I don't think of this recipe as insecticide. It's a poison. I would not use insecticides in my house. And what advice about sealing cracks to the outside of the house are you referring to?
Tyler W. Cox in reply to NinzerbeanAug 2, 2009. 2:14 PM
Sorry, but this mixture is an insecticide. http://dictionary.reference.com/browse/insecticide "A substance or preparation used for killing insects." Don't let the word worry you though; technically, table salt is a herbicide.
NobodyInParticular in reply to NinzerbeanJul 27, 2009. 5:13 PM
Good point about the types of food; it is important to vacuum regularly. Roaches can't, however, live more than a few months or reproduce with no water source besides the air. This is particularly true if their only food is dry nail clippings. I used the word insecticides because they are defined as chemicals intended to kill insects. You are probably thinking of a particular class of insecticides, like organophosphate. Some of them are much less toxic to humans and pets, some are much more toxic. As pesticides go, boric acid isn't especially dangerous in single doses. To kill half of a batch of rats, each has to eat a whole 2.660 grams per kilogram of bodyweight (Rat LD50). The lowest dose ever reported to have killed a human was 0.200 grams per kilogram (LDLo). On the other hand, if one is very concerned about the dog or baby eating traps, food grade diatomaceous earth is not a bad choice; it is totally inert in bodies larger than bugs' (provided you do not breathe it in). The advice about sealing cracks was in your picture labeled "expandable foam insulation to prevent bugs from entering". That's good advice too, as you want to limit the number of roaches coming in from outside while you are killing the ones already in the house.
Ninzerbean (author) in reply to NobodyInParticularJul 28, 2009. 11:10 AM
I think your comments are very helpful but I still think that roaches can live on dust, skin flakes in the air, the water that sits in your faucet or the toilet, condensation on pipes, glue on boxes, etc I could go on and on, but these are the reasons that taking away what we consider food and water is just not enough to combat them. I thank you for your "smarts" on this matter but I had been living with this system used by the pest control company for many years and everything was fine until they stopped using it. That's all I'm trying to say and thank you for reminding me about the expanding foam, I had forgotten that.
LittleWolf in reply to NobodyInParticularJul 28, 2009. 12:00 AM
You'd be surprised at how hardy those creatures are. Hate to reinforce any stereotypes, but where I lived in Mexico as a kid there was a ton of roaches. It was a very arid location, high in the mountains, with very very very very little water. My mother battled endlessly against them, pet food was always sealed in a plastic bag out of reach after 8pm, no water, food, dishes, toothpaste, toothbrushes, soap, candles, garbage or anything could be out, because otherwise roaches would walk over our dishes or clothes and we'd have to rewash. Our pets were also cleaned after incessantly, and we had no close neighbors. I remember moving the fridge with my mums once, to clean behind it and it just exploded with roaches... At least I learned valuable life lessons about animals and insects, and the importance of keeping your house clean.
Ninzerbean (author) in reply to LittleWolfJul 28, 2009. 4:56 AM
Oh your poor mom, but LW, she kept your house clean to the extreme and you still had roaches. I know you know how glad I am that this is behind me, I really was starting to hate my house.
LittleWolf in reply to NinzerbeanJul 28, 2009. 9:16 AM
We did try poisons once in a while, until one of our cats got sick with it. He was a roach hunter, and apparently the poison passed on to him. He did not die, but he looked like a goner. After that we stuck to guerrilla warfare against them. We would strike them where it hurt to most; behind the appliances that generated heat. The roaches frustrated us greatly, you can't feel comfortable; specially in your kitchen. One one occasion one even managed to get into our drinkable water and it we had to dispose of it all. It is very expensive, since we don't get drinkable tap water. I learned to recognize the signs of a colony, which places they were more likely to nest in, and how to track them back to it. Ironically, their biggest nest was not in the kitchen, but inside the old box television we had...
boredsahm in reply to LittleWolfJul 31, 2009. 8:40 PM
how do you track a roach and what signs indicate a colony?
LittleWolf in reply to boredsahmAug 2, 2009. 7:53 AM
I am not an expert on roaches, so I can only tell you from my personal experience. When I was a kid, I noticed litttle roaches did not go too fr from where their nest was, while the big roaches ventured farther and would tend to make a new nest somewhere close by. Roach feces look like tiny black dots, the more you see, it means that the more roaches travel that path, and it usually leads to a colony. They don't normally walk accross a room, but they hug the walls and walk behind things, that's where you'll normally find the communal roach paths. Their nesting sites vary a lot, in our house it was inside a TV, in my cousin's apartment in Chicago, it was on the bathroom wall. You'll see roach droppings around the entrance, as well as hollow shells stuck around, and black/brown stains that look like dry coffee spills. Some people can go years without realizing they have roaches in their homes, because they never see them in daylight, and can't recognize the signs of roaches. I've walked in people's homes and immediatly see roach crap and trails, but the homeowners are not aware at all. One particular instance I remember was this family with four small children; their house was infested, but the roaches' colony was in the basement where the people rarely ventured. The roaches would climb up at night to the kitchen thru the water pipes and eat from the food the kids would discard around the house. The mother wouldn't believe me, so I invited her once to get up late at night and turn on the kitchen light and see if she saw anything. It wasn't long before she was asking me if I knew anything about roach poison.
Goodhart in reply to boredsahmAug 1, 2009. 6:27 PM
Indeed, one roach indicates many more not seen.
Ninzerbean (author) in reply to boredsahmAug 1, 2009. 3:09 AM
My understanding is that they all live in Colonies - maybe you could ask LittleWolf that question. I am not as brave as he is. I never want to find a colony again. I saw a colony move one night - it was a river of roaches. Above my head. In my mom's old house. Probably where I got my phobia.
LittleWolf in reply to NinzerbeanAug 2, 2009. 8:02 AM
A friend told me once, about the wild roaches. He lives in Baja California Sur, and he told me of this occasion in which he went camping with some friends. In the middle of the night, as they were thinking of putting off the fire and going to sleep, when he says they starting hearing this "swish swish" sound, figuring it was probably the wind. Then they started seeing some roaches all around, walking over their stuff. Dozens, then hundreds, then thousands, a huge river of roaches covering the ground all around them. And as fast as they came, they were gone.
Ninzerbean (author) in reply to LittleWolfAug 2, 2009. 8:26 AM
Yeah, that was it. B.G. - beyond gross.
Ninzerbean (author) in reply to LittleWolfJul 28, 2009. 11:01 AM
Wow. I propose putting the bait in places that my animals can't get to but of course I can't prevent the cat from eating a poisoned bug. He is more fond of the poor lizards though. I thought I had a bad problem but your family's was much worse. The people who lived in my house before I bought it were very dirty - at least that was the way they left it for me, and that was probably what started the problem.
Ninzerbean (author) says: Aug 2, 2009. 9:00 AM
To everyone with concerns of toxicity, this is a quote from the Wall Street Journal ( 7/30/09) from an article by Gwendoyn Bounds on natural pesticides; "One day my dog Dolly got free from her fence and gobbled up a mouthful of the boric-acid bait. I called a pet poison control hotline (800 213 6680) and was told not to worry, that the active ingredient was "very safe" with low concern for toxicity, and Dolly would be fine". Though I still say to place bait out of reach.
gwendolyn bounds in reply to NinzerbeanAug 2, 2009. 11:00 AM
Hi -- I'm the author of the WSJ piece you cite. (Full story here: http://tinyurl.com/nvw5qx)

Interesting dialogue you've got going here and thanks for reading. It's important to note that amount of product my dog ate was very small. When the poison control hotline responder looked up the details on Mother Earth Scatter Bait, they found it wasn't likely to harm her, particularly because the amount of the boric acid active ingredient (5%) was so small.

Their determination squares with information about boric acid on the National Pesticide Information's Web site.

http://npic.orst.edu/factsheets/boricgen.pdf

Obviously eating any isn't ideal, but in comparison to other products not as harmful.

Good luck with the roach control.
albylovesscience says: Aug 1, 2009. 11:54 PM
boric acid is very dangerous to you and your family if applied incorrectly it must be applied into cracks and corners (it can also mean big trouble for asthmatics)

I do not corrently have a problem with roaches, but I'm more concerned with spiders. In the southern hemisphere (argentina, australia and chile), there are two common household toxic spiders: the (southern) Black widow and the Chilean recluse spider. Would it work on them too?

esotericman in reply to wgarciamachmarAug 1, 2009. 10:55 PM
If you have spiders then you have two things, a place for them to live (including hard to find water) OR your home has food for them. Get rid of the food, no more spiders.
Goodhart in reply to wgarciamachmarAug 1, 2009. 6:32 PM
if you don't mind centipedes, they eat spiders (I think anyways)

No, unless you could get them to eat it or walk across the powder. Try posting your question in the "Questions" part to see if anyone knows anything to do.

This is a very sweet and well documented instructable. I'm lucky to not live with roaches right no (not sure what drew me to even read this, but I'm glad I did!), but I will sure remember this when the time comes. I remember the first time I saw a roach fly. Holy s**t. Sure, they're called Palmetto bugs, but you can call them Happy Rainbow Fun Bugs for all I care - they're still roaches! Gross!!! Ok I'm better. Great instructable. Great pictures. I love your kitchen and am v. curious about all of the other pictures you have here!
Goodhart in reply to scoochmarooAug 1, 2009. 6:29 PM
Yeah, I even consider so called Water bugs, roaches, even though they really aren't the LOOK like giant roaches.....I have seen them grow bigger then my big toe....*shiver*
Ninzerbean (author) in reply to scoochmarooJul 27, 2009. 10:57 AM
You always make me laugh Soochmaroo. The pics of all the bugs are from my yard, the heavy set guy was the artist and sadly he died very soon after those photos were taken. I'd like to say he caught a bug... but I can't. He was a great artist.
eglentyne says: Jul 29, 2009. 2:21 PM
Thank you so much Ninzerbean! We are here in South Texas, so roaches are a constant, even with a clean house. We have used Boric Acid powder to great effect in the past, but I like the idea of being able to 'stick' it to places where the roaches go but the powder won't stay. Our boric acid was white, so we added some green food coloring to it, making it easily identifiable to the people in our house. We have dubbed it the Green Goo of (Cockroach) Death. :)
Ninzerbean (author) in reply to eglentyneJul 29, 2009. 7:37 PM
Awe, thanks, I didn't even know there were roaches in (South) Texas but I have learned there are roaches in Mexico so it figures.

Great instructable. My mom was so afraid of creepy crawlies, she couldn't stand the idea of spraying them with flit (her name for bug spray) and hoping they would die, she had to make sure. She'd nail that bug with her flit and drown it. I guess she didn't mind cleaning up a puddle if she could be sure it wouldn't move.
pindalanderz in reply to rookie1Aug 1, 2009. 10:02 AM
tell her to combine her "flit" and an overclocked adjustable lighter. that takes them out even faster.
Ninzerbean (author) in reply to rookie1Jul 27, 2009. 2:29 PM
Once, I ran next door where construction guys were working and begged for help with a roach I found in my studio, one of the men came over and caught the roach and get this - he squished it between his fingers, it was the grossest thing I have ever seen.
Goodhart in reply to NinzerbeanAug 1, 2009. 6:22 PM
Where there is one in plain view, there is a large family of them behind the walls or in a basement. But this is why Roach Pruff works so well with roaches, since they are social creatures, if the powder is kept dry, and they run through it, it clings to them and they spread it amongst their family, and is slowly wipes them out. Ants are harder to get to crawl through the stuff though....a little powdered sugar mixed in gives them incentive to take it home :-)
TwinFlower says: Jul 31, 2009. 5:20 PM
Thanks for the info Ninzerbean. I don't have an issue with roaches but I do have an issue with ants. After a quick google search I found that Boric Acid is also death to ants. I will have to try your "recipe" and see if it will work on ants the same way.
Thanks for the idea. I have been going nuts trying to find a cheap alternative to getting an expensive exterminator.

Great! When I went looking I went to the little local hardware store in my neighborhood and of course all they had was Roach Prufe so that was what I bought not knowing it was such a common chemical to find.

Thank you for posting this Instructable. I had forgotten about this technique. Excellent work ! I've mixed up a batch now And it's in place to get rid of a few annoying 'roaches that have taken up residence in my kitchen cupboards. It's Winter here (Southern Hemisphere), so they are looking for warmth and the occasional bite to eat. Just a point - Those little black ants that invade during Summer, this recipe will also assist with their removal. Thanks again.

dchall8 says: Jul 26, 2009. 3:08 PM
The idea of getting roaches has universal appeal...in the USA. Surprisingly some people elsewhere have lived with roaches for generations and believe they bring good luck to your kitchen. If you just follow the instructions on the bottle of Roach Prufe you can save yourself a lot of hassle and the slight extra cost of mixing up the extra ingredients. You used 2 cups to do a 2400 square foot house. Since 1981 I've done three houses (with garages), two apartments, and a school library and have not used 2 cups yet. All you need is a light puff of dust out the nozzle poofed into a few strategic spots and you're good to go.
Ninzerbean (author) in reply to dchall8Jul 27, 2009. 4:33 AM
Oh sure, I had a bit left over but you would be surprised how the volume changes when you mix the powder into a paste. I like a really clean house so I tend to vacuum a lot - once a week I guess and I don't have carpets. It does take time to do the whole house my way but it's really not a hassle to mix it up. The cost of any syrup besides maple is minimal. Maybe what I did was over kill 10 months ago but I was in a real state of hating my house, anyway it really has worked.
NightFire says: Jul 26, 2009. 11:11 PM
I despise roaches. Before I ever move into a place, I get Combat Roach Gel and Bait and caulk all of the roach places, then place a bait in all of the hidden corners. The stuff is great. I also have pure boric acid (get it from Wal Greens, or other similar places, less than $2.00 for a pound) that I use in various ways. The last roach I saw (in my place) was about 20 years ago.
