Picture of No More Roaches

I have wanted to write this Instructable for a long time but could not bear the thought of a photo of a roach. I found a plastic one; problem solved. I think you get the idea from that sentence that I am just a little bit, somewhat, sort of, come to think of it, mildly, TERRIFIED of roaches. This is the story of how I got rid of the roaches in my home and they have stayed gone for 10 months now after just the initial treatment.

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

Step 1: What you will need

Picture of What you will need
maple syrup pour.jpg
mixed.jpg

Boric acid powder*
Karo syrup - you may substitute honey, maple syrup, pancake syrup or make a simple syrup of sugar and water.
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 flour - any kind of flour is fine: white, whole wheat, rice, etc.
Enough Karo syrup, or what ever sweetener you choose, to make a peanut butter-ish consistency mixture

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

For a 2800 square foot home with 4 bathrooms, I mixed 2 cups of boric acid with 1 cup rice powder (any flour will do) and about 3/4 cup of Karo syrup. I used a plastic bowl to mix in and stuck the bowl and left over bait up into the attic/crawl space when I was done baiting. If you don't get finished baiting in one day put the bowl into the fridge, covered, and it will stay workable for another day or two.

*(Sometimes available in hardware stores in the US as "Roach Prufe" (this was the only way I was able to buy it, the canister is 98% boric acid and 2% blue coloring). Also, commenter ScottP6 says he was able to buy boric acid on Amazon for $7 for a pound. That is enough to share with neighbors and friends for years. Any boric acid that you find will be fine though, just make sure it is mostly boric acid.

Ninzerbean,

First off let me start by saying thank you so so so much for sharing this! I finally have my sanity back after endless nights of sleep deprivation, and hugging a can of raid every night! (not literally, but yes always ready on my night stand). -- I apologize for the length of this--

My family and I moved into a home that my father owns and was previously rented out to filthy tenant. Of course, it was infested with huge flying American cockroaches. I cleaned every inch of the house literally on my hands and knees & repainted. I too am TERRIFIED of roaches, and can't count how many times I cried, squealed, jumped, and yelled for my husband every time I saw one. At times I would be brave enough to spray them myself, but they would charge towards me!! AHH, My husband finally got tired of all the crying and complaining & called a professional exterminator. He came and sprayed outside and the baseboards.

I would see some dead, but I would still see a lot alive, if not more than ever. I studied them one night sitting at the kitchen table around midnight and I noticed that one by one by one they came out from behind the kitchen cabinet where the sink goes. Long story shorter- there was a nest back there & a hole leading right outside. I took the entire cabinets to the dump & fixed the hole. ( I installed all new cabinets)

I WOULD STILL SEE ONE IN THE RESTROOM EVERY NIGHT!!!!!!!

SO, this is where you come in! I did EVERYTHING you listed in the steps. I have gone through 4 cans of foam, and atleast 8 of silicone caulking. This house had so many gaps, and crevices! I spent countless days just sealing every room! In addition to this, I also bought new weatherstripping.... I strategically placed the boric acid paste in every room, every outlet, every door way. I didn't skip a single one.

I HAVE NO MORE ROACHES!!!

After 2 or 3 days of putting the paste, I saw ONE live one... It's now been two weeks and I haven't seen one. Not even a dead one.

I'm just in denial.. Is this real? Are they really gone?!

What you posted here works! ....Don't take "shortcuts", & these steps do pay off.

THANK YOU!

Dear Dseg1512,
Thank you for taking the time to write. Comments like yours make me so happy.
I recently (6 months ago) moved in an apartment with old neighbors and people who live above me. Well recently killed a few without knowing what they were and asked my girlfriend if maybe she knew and she had no clue what i was talking about like i was a lunatic. I saw one in the bathroom and tried to kill it but they can fit through anything (tried using a brush i dont care i throw the thing away and buy a brand new one) i am in the process of moving so i brought some boxes home which i think might have been the route cause of this whole nastiness! I read the steps to moving whwn you notice you have roaches but its all mind boggling, i have never seen or had roaches in my house in my life! Im a total neat freak so i had no idea about them until i read what they were and im horrified and disgusted! I wanted to tell the apartment manager but itd only make a bigger deal out of this. As of this moment i am not sure what to do, i have TONS of clothes more so than a 21 year old guy should have and im afraid to even touch them now because roaches are the nastiest thing in the entire world and i swear to it! I mean ive had ants before during the summer but roaches!? Thats beyond ants, thats beyond anything gross! My question to you is, what exactly do you suggest i should do?
Also, it is 3:53 am and i am scared to walk anywhere or eat anything or even sleep for that matter! These things as what ive read can be anywhere its so gross! I certainly am not cool calm and collected about this one bit. My question still remains the same, but not just about the clothes. Lol. This "article" totally made me feel not so alone. Thank you and i hope you respond asap!

I think anything you're asking is probably covered in the article... The comment she added at the end even says something about clothes/sheets, etc... What else are you looking for, suggestion-wise?

Ninzerbean (author)  CristianoC24 days ago

Dear CristianoC2,

What exactly should you do? Well this "ible sort of kind of is all about telling you what to do, so I sort of am puzzled as to what to tell you to actually do besides to go back and read it and read a few hundred comments - those comments are so helpful. Then follow the instructions and you should be fine. Yes it is gross but you have to put it in perspective. There are worse problems in the world, right?

deago992 days ago
Thanks for the info, I made this today and baited my apartment. How long do it take before you know if it works or not?
Ninzerbean (author)  deago992 days ago
About a day. If you don't see results that soon you may not have baited your whole place, or you may have German's which live inside and therefore you have to find the nest and dispatch it first. Also follow ALL the steps - seal up gaps.
So I'm back I couldn't find my previous post to comment there so here's a new one back then I followed your method after like a lot of people sleepless nights with German roaches that infested my home and treatments and expensive fumigations that didn't work! Anyways after a whole week of deep deep cleaning and putting your magic potion everywhere after about two weeks I was almost roach free and after then no more roaches at all! Then a few months after I moved, I had no more roaches and I put the stuff around the kitchen and bathrooms of the new place, anyways everything was good until a week ago I bought my son a used tv and today I saw a German roach in the room where the tv is! I cried! I can't go through that again! I immediately made some more boric acid and put some on back of the tv and around the room and closets and other rooms and bathrooms adjacent to that room but I'm freaking out! I think the kitchen should be ok since I had put the boric acid mixture down 4 months ago when we moved but I still put some extra, do you think I have a new infestation within the week the tv has been here? And do you suggest I re-do the whole house or should that be ok?? The tv is mounted to the wall otherwise I would've thrown it out but then again the roach was already out so I'm not sure it would've done any good either! Thanks so much for your help! I really hope I don't have a big problem again it was horrible!
Ninzerbean (author)  belma.rueda3 days ago

Belma.rueda, so sorry I missed your comment 5 days ago, I was traveling and working on my ipad which is hard to do, anyway thank you for writing. Oh those nasty TV's! I am afraid there will be more than the one your saw. You need to get that TV vacuumed and vacuumed! There could be a real infestation inside and you don't want them to find any more hiding places. The German's are just terrible to get rid of. I don't think you need to re-do the whole house if you did it right the first time, that will last for years. I'm just worried about how many are in the TV and if they have spread. I think for your peace of mind you have to get that TV down and examine it to make ultra sure. Keep in touch. Good luck.

Hello I wanted to know will any brand of boric acid work or does it need to be that roach prufe I'm looking for online at the different hardware stores and they don't seem to carry it thanks
Ninzerbean (author)  helloitzme693 days ago

Any brand is fine, just try to get one that is in the 90% or higher boric acid. Sorry for the late reply.

We have been battling this war for almost two months we've been sprayed twice and baited once by the "pros" I just made this mixture and put it everywhere like you said along with some serious deep cleaning. Haven't seen any upstairs or in our bathroom. Only the kitchen and now the living room. This situation is literally making me crazy I'm freaking out everyday I refuse to eat or cook at all in my house until this problem is completely gone. I am truly praying this stuff works! Eating out everyday and the lack of sleep and amount of stress is wearing me and my wallet down!
Ninzerbean (author)  JessW33 days ago
Hi JessW3, I know, I understand. It does seem to cloud everything. I promise though that this will work. Most importantly seal up any areas in the house where they can enter from the walls (where they live) or the outside. Get rid of cardboard boxes. Pull out all the appliances that are hooked to water and see if you need to seal the holes for the pipes that come into the inside from the outside to the appliance.

I have said this before but it doesn't hurt to repeat it - killing them does not last. This bait is something they will bring back to their colony, feed to their friends and watch them die. Then they will communicate to each other not to go back to your house. People don't believe me, they say they are not like bees. But in some ways they are in that they do communicate to each other. Of course if you have German's it is much more difficult to get rid of them because unlike the large american ones they live inside. Sometimes they come in in a play station, or a used microwave.

But you are going to be fine, this works. Keep in touch, read a few hundred of the comments. Share how it goes for you.

Gd afternoon Ninzerbean, I moved into my apt a few mnths ago and have in this last month strted seeing roaches running out here and thr. This is a very old building and cld tell from cleaning b4 my initial move in tht thr was a roach problem at sum point but thght that it had been taken care of since my apt had been vacant for over a yr and tht im really just now seeing them.I hav a 2bdrm apt with living rm dining rm and 1bthrm but i hav only seen them in my kitchen coming from the cabinets and sink area my bthrm near sink area and in my hall from crevices whr the wall and floor meet nvr in bdrms living rm or dining rm. I strted out just using Raid spray and i noticed them coming out more i guess running from the fumes...idk but i kno whr thr are a few thr are a thousand!!! Im afraid of the pests and its frustrating but i cnt live like this even with the few roaches i hav seen!! I am a clean person i sweep and mop daily i dnt leave food out and i keep kitchen clean and dry no dishes left behind dirty in sink but i still see them (although just a few) i hav spoken to neighbors who hav lived here for several yrs and they also hav the issue which i knew since i hav nvr had them so i cldnt hav brght them...my issue is im so afraid to bomb my apt for fear tht my problem will get worse and they will come running from everywhr or strt running throughout the rest of the house and take over!!! My other concern is tht if my neighbors are not taking steps to get rid of thr bugs tht i will always hav the roaches!! I came across ur solution for this and hav been reading comments and feedbck all morning and feel hopeful tht this can b remedied and i too can b roach free but can u tell me how effective the bait will b for my home even if my neighbors choose to just deal with the bugs and not do anything to get rid of them?!?! I hav the ingredients for the bait and plan to treat my entire apt and i most definitely need the product to seal the holes whr the pipes are (they are huge way too big for actual size of the pipes.) Thr is water damage under kitchen sink i can see so i think tht is whr the majority of them are living but bcuz i kno the whole building has had the bugs for yrs i just want to do wht i can to clear my home!!! If u cld answer my questions on how to handle my situation with my neighbors taking no action and how it wld effect my goal to get rid of them i wld greatly appreciate it!! Any ideas and/or suggestions are welcomed and if i didnt provide sum info u need please ask!!! I am so paranoid i get up at nite to spot them i cnt sleep and so worried they are going to totally invade and take over my apt...Im a single mother of 1 and cant afford to pick up and move so if i can solve this problem with ur bait it wld b a blessing!!! Thx and i hope u can help me!!!
Ninzerbean (author)  twhite07828 days ago
Dear Twhite0782,
I think that your problem CAN be solved. I am about to buy an apartment myself. Not that that matters but I too will for the first time be dealing w neighbors. So first of all sealing up your space so roaches can't come in is the number 1 most important thing to do. I do not know about bombs but can only imagine that they are a short term solution. I believe that sealing and baiting will be the only thing you need to do. If you see any live roaches after that there must be a spot that is still open.
I know you are sure you didn't bring them but is there anyway they could've come over with some video game box or appliance? I have been running this 'ible for so many years and I have read horror stories of appliance infestations that the owners had no idea about.
I also urge you to have your neighbors read this 'bile. The buggers live in the walls so if everyone can just block up openings with caulk and foam and spackle and seal the home the bait will do the rest and they won't come back for years and years. But even if your neighbors don't do anything, I think that surely you will soon have no more roaches.

Hi we just moved out of a highly infested apartment. Where we live now there are no roaches of any kind. But......We brought em with us. I've killed about thirty this past week. Yeah that many. I've set traps and am cleaning every night. Not leaving n e signs of water. How effective is this and how long will it take to see results thank you !
Ninzerbean (author)  ladyofcesar1 month ago
I am going to suggest that you read some of the 800 comments to get an idea of how effective this is and how long it takes to see results. Perhaps there in the comments you will see similarities of some other people in your situation and can therefor gage how long it will take, what it will take (getting rid of the objects you brought with you that are being used as a home for the colony) so that your question can be answered. I wish I could help you more than that but without more information about your situation I can only suggest that if you did not see your questions answered in the 'ible itself then the comment section would be where to look.
Yes. The comments are very helpful. So we Apparently brought em in air conditioners tvs and space heaters. Its starting to get bAd my nine month old cant sleep in his crib n e longer because he has asthma n starts to have cough spells becAuse bAby roaches are all over it. Where do i put the mixture exactly ? This house has no roaches but we unfortunately brought them with us. Thanks for responding too.
Ninzerbean (author)  ladyofcesar1 month ago

See step 7 for where to put the mixture. Maybe you are only seeing the first 2 steps. You have to find those things that you brought the roaches in on and maybe get rid of them or take them apart and then use an air gun compressor type thing to really clean them out. I tried this myself with an air conditioner and I could not take it completely apart, after 2 weeks bagged up in the hot sun with a box of boric acid sprinkled all over it, it still had roaches and I had to throw it out. So I know first hand how hard it is to get them out of appliances. It may be impossible. Some have suggested freezing the appliances. I don't know. But act fast before they get into more places. Vacuum every day. It's really hard when they have built a colony inside your house. It can seem overwhelming but it will get better every day if you just keep vacuuming, and bait too, but you need to knock down the population when it is this bad, before the bait will work. Keep me posted though, I really care.

So i am buying the ingredients later today. We've been low on funds and havent been able to buy the stuff lol. I will keep u posted. Wish me luck !!

Hi,

I signed a lease for a vacant house and while renovating it (long story), I found out it's infested with German roaches. I hired an exterminator and he put out the magic peanutbutter, but the German roaches are harder to kill than the palmetto bugs.

I THINK I have an advantage because I'm not moved in yet, but it's been 3 weeks and these beasts are still there (although much less).

Before I hired the exterminator, my neighbor bombed the house, which killed about 40% of the population, I think. Then I hired the exterminator, and his bait also produced a large amount of dead roaches, but only at FIRST.

Then I bought a steam cleaner and I blasted the roaches out of the kitchen cabinets and from underneath base boards, and then I had the guy put out more peanutbutter (it's called Advion Syngenta Cockroach Gel Bait, and after I saw what he used I ordered it online.) Anyway, so I cleaned like a mad person, then my neighbor set off some bug bombs, then I cleaned again, then the exterminator put out the Advion Syngenta Cockroach Gel Bait. And you know it LOOKED like all the roaches were gone because I did not see any new ones that were dead lying aroung, but then when I started to paint the house, I saw a bunch of antennas sticking out of all the outlets! My roaches live in the wall, quite happily, actually. So i FREAKED OUT because they came out and feasted on the fresh paint. So I cleaned some more, and then made your paste with really delicious maple syrup that I actually did not want to share with those beasts and I took off ALL the light switch plates and outlet covers and I put the bait there. And I realized I had access to the inside of the walls through some of those light switch holes. And I threw Harris Roach Tables (made of Boric Acid) into the walls through the outlet and light switch holes. I am hoping that the roaches will eat the boric acid in the walls and die before they make it back into the house :(

I wanted to move in this months, but the roaches are still there :( It was a horrible, heavy infestation, and I decreased the population, but I just found out that the fridge is infested with roaches - how can I get them out of there? Like how do I get rid of the nest? You always said "get rid of the nest" but HOW?

Please, could you tell me how I can de-roach the fridge? I do not have the $$$ to replace the fridge. Thank you so much

Ninzerbean (author)  brathly198223 days ago
Awe, this is such a drag.

When I say get rid of the nest or infestation I mean physically - vacuum vacuum vacuum. I really am so sad to read this, I wish I could make better but I am stumped - how are they getting in? Are there any holes you can plug up? Can you rent a large shop vac for a week and vacuum inside the walls? Is there carpet? Can it be removed? Maybe they are eating the stuff under the carpet? I am brain storming here - but do not move in until you have this fixed - as in NO roaches. And for the time being unplug the fridge and anything else that stays warm. Let me know if any of these ideas help. Obviously they are really hungry if they are eating paint. Hmmmm, what could you put in the paint that might kill them? Boric acid! Some people have lured them out with bowls of pasta water, you know the water that has a bunch of starch from cooking pasta in it.

Hi!

Thank you for replying to quickly!

I heard that German roaches do not come in from outside, they are only brought inside. So the previous tenants brought them in, and I think the reason that I haven't been able to get rid of them is that there were still eggs in the wall that were not affected by bait and spray.

It takes up to 4 weeks for the eggs to hatch, so even if it looks like all roaches are dead, there may still be some unhatched egg sacks somewhere, that hold up to 40 tiny baby roaches.

I think I'm dealing with the 2nd generation since I've started fighting them.

Unfortunately, I do not have access to the walls :( the whole in the wall are just big enough to push a boric acid tablet through.

In addition to baiting, I also dusted every crack in the wall with Diatomaceous Earth. I'm just using all methods I can think of at the same time. I want to get rid of the roaches sooooooooo badly!

Ninzerbean (author)  brathly198223 days ago

Well be sure to stay in touch, everyone can learn from what you are learning. Let us know if the diatomaceous earth works. After you move in go and get a cat. They love chasing roaches but I just would not want to pet mine for a long time afterwards. I can still picture in my mind little Peanut with a roach in his mouth, a big palmeto bug, he's been dead for 15 years and it still grosses me out.

Oh my kitty has been on top of the hunting game! She first stalked the bathroom then kitchen and I told my boyfriend I bet anything she's hunting those suckers at night!
I wish my mittens (thats my cat lol) would hunt n kill them. She just would watch them go by.

hi,

you may use some insect growth regulator to break the reproduction cycle of the roaches. There are several products, such as "Gentrol Point Source IGR Insect Growth Regulator". combined with the boric acid you should get rid of your pest.

raerae37510 days ago
Okay so inam very excited to try this I am going to do it tomorrow yes this is posted late cause I cannot sleep and am paranoid so long story no way to make it short.
I just moved into my apartment three days ago and keep seeing a ton of roaches they were all coming from behind the cabinets in kitchen and bathroom so right away I started spraying and put down boric acid behind fridge and under dove and sink well they still kept coming out during day and night so then I decided to coulk the cabinets in kitchen behind fridge and under counter top and after I did that I bombed twice so I have seen way less you knows lately then before but now im seeing them coming from under the light in kitchen and from the top of cabinets so its getting to the where me and my mom are so paranoid that its effecting our sleep. So I decided to do some research and found really svafy stuff that they can eat your skin toe nails finger nails leave lesions crawl in your nose ears this is not helping situagion but I am going to take off all plugs and do that stuff behind there and get the foam stuff cause I honestly don't know where to go from here cause I have a two year old and this scares me terribly. Thank you for all your patience reading this long story and all these comments makes me feel tiny bit better that ppl go through se thing
Ninzerbean (author)  raerae37510 days ago

Yep, we are all in this together. Knowing that there are lots and lots of people with the same problems helps. And you will get rid of your roaches. Promise.

My friend calls this morning and asks if she can stay with me and my kids a while. I say it's okay, then help her move her things (in plastic garbage bags) into my 4 story home. I have 5 kids, so crumbs are a given. She tells me once her stuff is already in my house, that the apartment she was only in a week, had a few roaches. Then the land Lord sprayed and she hadn't seen them Again. But she brought things from there into my home and now I'm petrified. What can I do?
Ninzerbean (author)  SarahE610 days ago

Well this is one of those things that happens to me all the time - no good dead goes unpunished. The only bad thing I think that your friend may have brought over are electronics - play stations, microwaves, stuff that roaches love to live in 'cause they stay warm. So inspect those items very very well. There would be no harm to bait your home but at 4 stories this is going to take a few days to do. Just to be on the safe side of course. I think it is important to have your friend and you look very carefully at everything she brought with her. Keep in touch, let us know if you find anything.

hmr82315 days ago
I am going to try this, since we moved here 6 months ago we see a huge dead bug every now and then and my boyfriend convinced me they were beetles from outside but this morning was the last straw I went to pick up a dead bug with toilet paper and it sprung to life and went under my sink! It was like 4 inches long I am traumatized, my question is will this harm me if I'm pregnant, I am 5 months
Ninzerbean (author)  hmr82315 days ago
No, just do everything I say to do, dust mask, etc. It's not something you want to breathe, pregnant or not. Get your near-sighted boyfriend to mix it up, outside, with a dust mask. But there is no harm in your applying it.
