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 described here, the roaches stayed gone for 6 years, I baited one more time inbetween. It is important to click the button right under the title that says '8 Steps' 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, might be answered in the comment section. Which is not to say not to ask questions, please by all means do so if you need to.

Step 1: What You Will Need

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.

<p>Ninzerbean, </p><p>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--</p><p>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 &amp; 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 &amp; called a professional exterminator. He came and sprayed outside and the baseboards. </p><p>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 &amp; a hole leading right outside. I took the entire cabinets to the dump &amp; fixed the hole. ( I installed all new cabinets)</p><p>I WOULD STILL SEE ONE IN THE RESTROOM EVERY NIGHT!!!!!!!</p><p>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. </p><p>I HAVE NO MORE ROACHES!!! </p><p>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.</p><p>I'm just in denial.. Is this real? Are they really gone?! </p><p>What you posted here works! ....Don't take &quot;shortcuts&quot;, &amp; these steps do pay off.</p><p>THANK YOU!</p>
how long did it take to see get results after placing this remedy in the recomended places?
Nevermind. I read 2 or 3 days. Dee dee dee moment
Dear Dseg1512,<br>Thank you for taking the time to write. Comments like yours make me so happy.
Hi Ninzerbean, it's been a year since I tried your magic &quot;peanut butter&quot; &amp; had been roach free living in bliss. Until now.<br><br>Sadly, they've come back with a vengeance &amp; I've been finding a dead one every morning for the past week. Tonight I'm awake because I found a live one and cannot sleep. Should I reapply the mixture?<br><br>I have no idea what could've brought them back? We haven't brought anything into the house &amp; the foam remains in place. <br><br>Any advice is greatly appreciated
I thought they were gone four times and they kept coming back. The first two times they were still the big ones but the third time they were medium sized and then tiny. The tiny ones are the last ones I seen inside. I found out later thats kinda normal when you bait. I still see those things outside and thats why Im here. The shopvac is your friend ?. Im going to try this mix outside. I have no love for these things.
<p>Dseg1512, Something brought them in, not back, just in, you must have bought something that had them attached or inside, it could be as simple as a used game player, a box of contaminated food, a bag of potatoes. Just get on top of this right now and they will be gone. The bait does not wear out in a year, it just has to be something that came into your house that had them living in it. Anyway just re-bait so there is fresh lovely stuff around and it will be OK very soon. I may be about to have the same problem myself because I had to bring back a ton of stuff from a relative's home that was infested with roaches. I've already seen one dead one and I know there could be more.</p>
<p>Thank you, thank you, thank you! I am a neat freak, and I was struggling with bugs even though the house was spotless. It was incredibly stressful. I enlisted my husband's help, and we followed your instructions. I bought the boric acid, flour, and syrup at a Family Dollar store for under $10. We went through several cans of spray foam and tubes of caulk, and it took a couple of days to make sure we got every crack. We took off every light switch plate and outlet cover and put the goop inside. We did cabinets, door frames, everywhere. It has been a little over two months, and we haven't seen a bug since. I seriously can't believe it. We were so skeptical for the first few weeks, and we kept waiting for them to come back, but this stuff is MAGIC! I just cancelled my pest control service. If anyone out there is thinking about doing this, DO IT!!! I cannot thank you enough for this! It is life changing!</p>
Hi Tiderem, what a great comment. I'm going to feature it. Thank you for taking the time to write about your success. Once you no longer have bugs you forget how much angst they used to cause.
<p>I didn't even realize how many things in my life were revolving around those creatures! I can now have visitors without worrying that one will scurry across the floor. I can get a drink in the middle of the night without having to dry the sink afterward, and I can even leave a glass of water on my bedside table. The floor was spotless, and I would never have walked around without shoes on until now. I was living in constant fear, and now I can just relax and enjoy my home. What a difference! </p><p>Also, for those of you who are planning to try this, I used a Tupperware kind of container that was airtight, and the paste is still workable over 2 months later. No need to refrigerate! I have been putting a little bit on my porch around my potted plants after every rain to keep the ants out of my plants. </p>
<p>HA! I just posted a comment wondering if this would work against ants. So there you are! How well does it work on those nasty beasties, Tiderem?</p>
Yes this stuff even kills ANTS i used it with peanut buttter. I even sprinkle a band around our house when rain is not in tbe forecast.
Have not had ANY bugs in months! Haven't even seen one roach or ant dead or alive, so it seems to work for ants as well.
Boric acid can be bought at any hardware store in the poison section . Even in drug stores in eye wash read lables . 98% Boric acid is all you need it will kill all your bugs nothing else is needed . Pest control companies have been using it for years .
<p>I have bought the plain Boric Acid. I like those cheap chicken pot pies and will cook one and eat it saving the bowl thing it is in. I put a little Boric Acid in it along with a small piece of bacon from breakfast in the center. I place them under cabinets in kitchen and bathroom so our pets not get into it. It does take some time unlike a kill one now spray. But, they will be gone!</p>
<p>Dear Ninzerbean, I must write to thank you for this. My hubs made the dreadful mistake of taking a game system home that he found on the side of the road. Turns out it had an epic nest inside of you know what. We did some research and cleaned up target areas very well and sealed up all food, plus bought some gel bait which had actually worked quite well for me at an apartment about 15-20 years ago. Over the course of the next 2 months though we started finding more and bigger live ones. When I saw one crawling along a door board as I got coffee one morning, I reached my tolerance level (which was already next to nothing due to childhood and adulthood past trauma with the things). I began to research more to see what I should expect or what I was doing wrong, when I found this page. It took awhile to do our house because it's pretty large and tell you the truth, every single step could not be followed to the letter because we rent and we don't want to make the washer and dryer water hookups so difficult to access, for example. We didn't even foam up under the kitchen sink.<br>The day we began the process of applying the bait, before we had applied any, one adult came out in broad daylight. I was freaked because I already knew from what I read that it's a very bad sign when they come out in daylight, although he may have been disturbed by our cleaning and clearing activities. Anyway, after just getting a basic start with the kitchen stuff, we stopped seeing them daily. A couple days later, we discovered some super tiny (live) babies near the stove- a spot we frequently saw them around a particular cupboard- I realized not only did that cupboard have a sliding door that slid into the wall which was probably a prime breeding ground, but also we hadn't done a lot of bait there, so I baited up that door. The next weekend, I turned on the stove and a small one came out of the stove.... you better believe this was not a happy thing for me to discover. I spent that entire day getting into the cracks we had previously missed on the stove because I actually had to take part of the stove apart to get into those cracks that were full of caked in crumbs from a few years at least that we've lived there because we didn't know how to get to it before. After spending basically a whole day getting everything I could out of there and baiting some strategic spots around there that wouldn't affect our cooking.... well, we haven't seen a single one since that day and it has now been 3-4 weeks. I am SO impressed! And happy to have my wonderful house back!</p>
<p>Oh and I did also go around and do all the outlets etc. that I could around the whole house over the course of a few weekends, I read that you should here, even if you've only seen them in one place like the kitchen, like us. The game system had started out 3 rooms away though in the garage, so keep that in mind, and we never saw any in the garage after the first few weeks.</p>
<p>Roommate found a live roach tonight, a big one apparently. Will be revisiting the foaming step!!!! Looking for other commenters on seeing a big live one months later too, I know there was some with this experience..</p>
<p>CarrieW7, A big rain can bring in a roach or two - any chance you live where we have had all of this rain and flooding on the East Coast?</p>
<p>Hi Ninzerbean,</p><p>I was somewhat relieved to see your comment. I am actually on the West Coast and we did just have a good rain which we desperately need being in stage four drought at this point. I'm also still a bit concerned, it was a big one according to the eyewitnesses and not slow either. And in the most common spot we've ever seen them, that cupboard door. We had no outdoor or any nests before my husband introduced them to our home unintentionally and it has been so peacefully roach-free for several months I think now. Although on second thought, maybe a few of the suspicious mothy-looking things I wondered about before were actually just what I feared. Anyway, they didn't ever used to be here and I hate to think they're still nesting somewhere. They are the German kind, so they don't live outside from what I understand. Which is even worse, and I have no idea how when I put seemingly so much bait in their paths. We've also been struggling with a huge ant infestation pretty much since the end of the roaches. Apparently a big thing all around our area.... we never had them before either.</p>
<p>CarrieW7, This bait will work for ants as well, if you smear it along their paths, you will need hot water to clean up later but I did this at my mom's house and it worked with in hours. But on my next visit they were back so I did it again, I don't know if they are still gone but I think I was not diligent enough to trace them to where they were coming in.</p>
Ok I might be blogging incompetent. I've tried 3 times to comment and it never shows up. We had the magic peanut butter put in by the exterminator a month and a half ago. My husband just saw one in the kitchen this morning and killed it. Should I be concerned? Is this normal only a month or so in?? Should I call the landlord again?
<p>I think the politically correct phrase is blogging impaired. Or would it be blogging challenged?</p>
<p>They probably came up with a less effective peanut butter solution to keep their business. I'd do it myself, if i were you.</p>
Thanks ?
<p>I'll second the effectiveness of a borax-sweet stuff mix against ants.</p><p>Had a bit of a problem in the kitchen. Did all the usual clean up, clean and clean again routine and they were still around. Mixed up the dregs of a jar of strawberry jam with some borax, smeared a little bit on a couple of pieces of cardboard and put them where I'd seen the ants. </p><p>Next morning the bits of cardboard were swarming with ants so I disposed of them and replaced them with fresh bait. Next morning, same thing but not as many ants. By the fourth day there were maybe half a dozen ants to be seen and a week later, none.</p>
Big roach called a waterbug can find its way after a rain they are huge but not to worry they breed outside they dont infest like the german roaches
Hi!! I found your site in complete desperation. After reading several hundred comments I was convinced I'd try. So after 2 days of a complete cleaning spree and baiting every outlet and foaming every crevice I could find, im feeling hopeful. My question is <br>Is it normal to see them more after baiting? I believe I found the nest. Which was Christmas boxes stored in my living room cubby. I just threw the whole thing away. Oh, I live in Florida. So I'm plagued with German ???. Thank you so much!
Does this work for any kind of roaches? I have the small german ones, i think they are called. Is it a pointless endeavor for me to follow these steps? Is there something else I should do? Please help, anyone who has used this stuff for german roaches and let me know if you have had any success. Thanks.
Was hoping that maybe you still read these comments and reply! I have a roach problem, help!<br><br>Never in our lives have we had roaches. We are pretty clean people and have never had a bug problem before in general.. and then we moved to an apartment in a 4 bedroom flat in downtown Soulard (st Louis). This is a historic district so you are very VERY limited on what renovations you can do.. we are renting however. The building itself is very old. If I had to guess I'd think the are coming from the building next door..it's pretty close and the back looks uninhabitable.. However the interior of our placeisn't terrible, just a little outdated.<br><br>Anyways, the week before we moved my boyfriend went in and painted the whole place. He said he saw one roach but that's all and wasn't concerned. However it seemed that someone (landlord or previous tenant who also seems pretty clean, I viewed the apartment while she still lived there) left behind roach hotel trap things. She had moved out earlier so it had sat empty for a couple weeks. My boyfriend mentioned to our landlord he had seen a roach but our landlord insisted that they &quot;were just water bugs&quot; and he &quot;sprayed&quot; (what he sprayed, I don't know).<br><br>Fast forward a couple days and we are cooking our first meal in the new place.. right as it's done, I mean literally as we are getting plates down, 5 or 6 pop up over the back of the stove - a medium sized one and the rest were pretty small. Upon researching they look Ike Germans. We sprayed bug spray all around the area and chose to get take out instead.. but now we keep seeing them.. on the stove, on the counter, on and in the dishwasher (keep in mind these are all on the left side of the kitchen which is also the wall that faces that empty looking neighbor building)... now they are progressing to the other side of the kitchen which has the pantry.: if I flip on a light at night a couple will scurry under the pantry doors.. I purchased tempo spray for the baseboard and doors and advion gel bait but does anyone else have any tips?? I'm absolutely terrified of them! We've been keeping everything spotless, and luckily it seems they are only in the kitchen so far, however I've quit eating the food from home cause I'm too grossed out. <br><br>Oh and none of our neighbors said they have had any problems. What do I do?? We have a BRAND NEW $1200 washer and dryer in that kitchen that I'm 100% scared they are going to infest!
<p>Hi Tijo, We had them in our electric range and the dishwasher. What happens in the dishwasher is they come up the drains, then they go to the electronic panel of the dishwasher, behind the push buttons. They love the warm electrical circutry. The german ones are tenacious. YOu have to put bait in dishwasher, they love the dampness inside. One thing I recomend is after you use dishwasher, keep door open to let dry inside with ac on or heat. They can live months without food, bud only a week without water. They love kitchens because of food crumbles, ware electronic wires and mosture of sink and dishwasher. Good luck it is war against them. </p>
After you follow all of the steps and still have roaches lets talk - I don't think that will be the case of course, but you need to do that first. I do not know about the stuff you already used - I only know my method. Germans are harder to kill, it will take finding out where they are living in your house and getting rid of that nest - the vacuum will become your best friend, and then baiting.
I tried your bait last night and today i woke and found a dead roach! Im so pleased that it begin to work within one night! Thank you so much!
<p>This instructable saved me! We recently bought a home that unfortunately came with a ton of roaches. We spent the entire first weekend following the steps - bait everywhere and caulking/foaming every place we could find. Week 1 we kept seeing them but when we did we were careful to caulk up where they were coming from/running to. By week 2 we were seeing fewer and smaller ones. By week 3 it was only tiny ones and I am delighted to say I haven't seen one at all in week 4! Thank you, thank you, thank you! One helpful tip I read elsewhere is to get a good spray bottle and fill it with soapy water - that will freeze them in place until you can smash them (sorry, gross) - very helpful if they're running up walls or in hard-to-reach corners.</p>
Will this method work for silverfish?
I don't know, never tried it but if you do and it works please let us know.
I made this yesterday after my housekeeper had been to clean the house. I put it everywhere and wheh i got home there were even more cockraoches running around my kitchen than normal. I have no idea why that would be and what went wrong? I got up this am and opened the one kitchenboard where i normally see a few (and where i baited) and there they were walking around. Please help
This has happened before- I mean twice people have written of such a thing, apparently you have Germans, which live inside the home vs outside, I understand your frustration, others have written of this happening - but I think they are looking for food as they have found the bait dangerous. I hope you will see less every day and then none in just a few days, if not I hope you will write again. Have you put the bait everywhere - the whole house has to be baited, not just where you see the roaches. When I wrote the 'ilbe 8 years ago there were no German roaches where I lived, I had never heard of them. But according to the faithful who write in the comments this will work for Germans as well, pls keep in touch, and read a few hundred comments for help - example - maybe there is a nest in the kitchen you need to find and dispatch.
<p>hi, I made the magic peanut butter last night and put it out all over my house like you said. This morning I got up and I have live roaches every where and they come right up to you lol what did I do wrong ? Please help !!!!!!</p>
That's what happened to me
I'm at a loss. This is a new outcome. Wait a day and write me back.
Hi help please I did the remedy but roaches are appearing more and more I did it yesterday and I found more than six alive roaches in the kitchen. That was disgusting
Did you skip any steps? You spray-foamed under the sinks? Got into all the switchplate covers, etc. I only ask because you should have immediate results of seeing only dead roaches. Is there a nest inside - meaning you have German roaches - that you have not found? Is everything in plastic, no cardboard anywhere? Yes, that is disgusting, I feel for you, I just don't know what to say other than to make sure you did all the steps, it take a good 4 hours to do a small house.
I did all the steps yesterday. I mixed two cups of boric acid with one cup of flower, next, I put Coran syrup to make a past like pinaut. Then I did small balls I put them every where in my kitchen behind the fridge, every where in the kitchen. I found 7 german adult roaches and a lot of baby german roaches I am really concerned. Please please please please help me I am crying. I ca not believe how I cooked dinner it was so taught for me to be in the kitchen and meet a roach every 5 minutes. Now I am thinking about how to be in my kitchen tomorrow
<p>The purpose of the paste is to stick it to places that are out of the way and where roaches go - like the backs of your drawers in the kitchen, on water pipes under the sink, on top of doors, behind picture frames... I think you need to re-read step 7 to see all of the places to place the bait. I don't know why you made balls of it. You must first see if there is a nest in your house and clean out where they are living to get them under some sort of control first. Just baiting your kitchen won't help, you need to bait the whole house, you need to get inside the walls, you need to clean everything really well and if you think there are roaches in the kitchen find out where and deal with that first. I'm sorry I can't help you anymore than that, I know how terrible this is. Try reading a few hundred of the comments and see if you can glean any more knowledge from them for your situation. German roaches are very hard to get rid of because they live inside vs outside. You must get rid of everything they eat such as cardboard.Your vacuum will become your best friend. It takes a lot of work, but it will pay off in that you will get rid of the roaches. But you must bait the whole house, not just the kitchen.</p>
I will redo tho remedy I still have the ingredients. Tomorrow I will clean the whole appartments very well and after that I will make a past not balls in all over the house thank you for spending time and writing to me. I feel good when I read your comments
I just moved to New York. We rented an apartment of one bedroom. But I have a problem. I hate roaches and can't stand them. I sometimes see tinny ones, but the problem is I cannot even kill them. If my husband is home I would cry and tell him please kill it. But if I am by myself I would run to the room. I have seen them most behind the fridge and in the bathroom. I am about to use your remedy. I wish I will get rid of them as soon as possible. I am really suffering from them. They cause me to be stressful all the time. Today I bought the ingredients, and on Wednesday I will do it. Thank you so much.
Aw Zaloma,<br>I know how you feel, I really do. The only advice I can give you is that you have to put it in perspective - think of something much worse you would have to do, then trade that thought for killing a roach. If you put it in perspective you will see that you CAN do it. The first few are really really hard, but I promise it does empower you and you will become stronger than a roach. <br><br>Think how much you do not want a very small bug to have this sort of control over you. You can do it, I have faith in your abilities to see the larger picture. There are literally millions of people in the world who would trade places with you and live in a one bedroom apartment in the coolest city in the world (besides Tokyo) in exchange for dealing with some small bugs once in awhile, because where they live there are roaches every day, every hour of every day of their lives.<br><br>And the sooner you bait your apartment the sooner you will be roach free. Promise.
It's been a while that I've posted to this but I would like to say it's been almost 2 years ROACH FREE! Everyone is different maybe mine wasn't as infested as others. I know some people need to redo treatments every 6 months or so. I was at my breaking point when I found this and after trying so much this was my last hope. I had just moved in to my new apartment and there was roaches everywhere on the walls in cabinets everywhere. I cried for days trying everything I could to fix it. So I went on google and found this beautiful post. I did EVERY SINGLE STEP. It took over 4 hours to do a three bedroom two bath apartment. I put that stuff everywhere! And I found roaches here and there but DEAD. And since then I haven't seen any since. Please read everything and do ALL the steps. It will give you back your sanity. Thank you so much again my children and I are forever grateful!!!!!!!!
Dear Tasha,<br>Thank you so much for taking the time to write - I am so glad you are roach-free. I know what a relief that is too.
