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>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>
I moved into a rental house about a week ago and discovered the second night that it was infested. I went outside to take the trash out and saw dozens of roaches crawling all over the house and front door that night. I worried that they were probably inside as well...they were. I walked into a spare bedroom to get something and there was a huge roach on the wall. I'm 30 years old and have never lived anywhere that had roaches. Im terrified and creeped out by them. I live alone now so I had to get the broom and kill it. I was traumatized. I went into my bedroom to discover another roach. I killed it. There was another one on the blinds in the kitchen. I was horrified and realized I'd moved into a roach motel. I sobbed on the floor in my living room cursing myself for moving into this house. But I had already book marked this indestructible - I have an irrational fear of roaches and infestations so I had already researched how to get rid of them in case I ever encountered them.<br><br>I couldn't sleep at the house that night - I slept at my Dad's house. I knew I would not sleep for fear a roach would drop from the ceiling while I slept. I got to work the next day. The First thing I did was call the landlord who said terminix would come out the next day, which I knew would likely not have lasting effects but wanted them to come anyway because i wanted to come at the roaches from all angles. I went back to the house to begin the baiting. When I got there I saw a roach in my living room, during the day. I also saw many in the flowers bed by the front door.<br><br>Then I got to work: I cleaned behind every appliance, made the bait (boric acid came from Home Depot), got rid of all the cardboard, put all food in the fridge/freezer/airtight containers, spray foamed under sinks/behind the toilet, and baited behind every single switch plate and outlet, of which there were many in my house. I baited every door jam and window frame and pipe and kitchen drawer and behind appliances. While doing this I noticed there was a huge hole under the bathroom sink, one that foam wasn't going to fix. I let the landlord know and he said he would send a contractor out to repair it. I also was unable to move the dishwasher bc it was screwed in. I felt like the roaches were probably using those areas to come in from the walls/outside. I knew I would have to get those areas sealed up. <br><br>It took me about 2 hours to do the baiting - the house was already pretty clean and I did not have much cardboard. It didn't take as long as I thought to unscrew the faceplates. That night I waited to see what the roaches would do. I sat there in semi darkness...and they came. It was terrifying. I saw one in the kitchen and one in the living room that I killed. I slept at my dad's. The next day terminix came. They sprayed outside and inside, they baited (the peanut butter!) in the kitchen cabinets, and put a granular pesticide in the soil and flower beds. They told me I had two kinds of roaches - American and oriental. Luckily both of those nest outside. I thought i would see an improvement that night. I went out to dinner and when I returned I found two roaches in the kitchen. I did not sleep there. At this point I was not sleeping in my house, I was not cooking for fear i would draw the roaches in, I was taking all of my trash to other people's houses. I felt like a prisoner and slave to the roaches. But I had faith that the baiting was going to work once those holes were closed. The next night I found one having a party in my dishwasher. Didn't sleep there. <br><br>The contractor came the next day. He repaired the hole under the bathroom sink and foamed the areas behind the dishwasher. He also sealed some areas outpace as well. That night I saw no roaches and slept at my house for the first time in almost a week. I kept waking up in the night to check the kitchen and bathroom. I saw nothing. Tonight is the second night and I have not seen a live roach, outside or inside yet. I have seen some dead ones outside. <br><br>I know that closing that hole under the bathroom sink was the final piece that rendered this indestructible a success, it just took a few days. I think that is why I was still seeing some live ones after the baiting. I was so worried and terrified that I was going to be living with roaches for a year until my lease was up but I think this method really works. I also think the terminix treatment may have helped in the short run to bring down the roach population on my property. I hope to continue to see no roaches and I can actually enjoy my house now. Thank you so much for taking the time to post this. I wanted to post this comment so other readers could see how important it is to do all the steps (like closing holes and such) - I think that is why I did not see results for a few days.
Trudymollyfud, Wow! Thanks for posting, and I think you are very brave - no way would I have sat up all night waiting to see roaches. Your descriptions are great - I love the roach having a party in your dishwasher. The broom idea - wow again, no way would I have been able to do that. I think that this is the longest comment I have ever gotten and I applaud your attention to detail and memory of everything that happened. <br><br>I think that your taking the time to post your progress and success will help a lot of people.
I had to restart my comment. <br><br>Well I've made an account to share my excitement! The day I received my keys to my apartments I noticed there was roaches. I was so mad that I complained to the apartments, all they told me was they had pest control do a full cleaning so roaches might be coming out more &amp; not to worry. So I waited two weeks to move my stuff into my apartment. I prayed that the pest control fixed the problem. Guess what! It DIDNT! no surprise huh. So I tried everything I bombed my place I set up traps I even bought boric acid and put it everywhere. Still didn't work. I had finally given up and it was time to move my stuff into the apartment. <br><br>So the night before the move I researched one more time to see if I could find the answer. I came across this post. Since I already had boric acid I thought well it's worth a try. I read the comments and made sure I did everything right I was determined to get rid of these nasty bugs! So I stayed up for four hours opening outlets and baiting everywhere and everything. <br><br>After I had moved in I realized there was still roaches I thought to my self well I gave it all I had. But a couple days had passed and I saw maybe 3 roaches in my entire place. Then I didn't see any! (well none alive they were dead). I tried not to get too excited as I thought this is too good to be true. But as the days passed i didn't see not one roach. I think I cried for joy for a week. This had actually worked! If you are reading this and you're at your breaking point I'm telling you THIS DOES WORK! But only if YOU DO IT RIGHT! I'm happy to say my place has been roach free for three months THANK YOU NINZERBEAN! for this post. Sorry for the long comment! Thank you again!
<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>
Dear Dseg1512,<br>Thank you for taking the time to write. Comments like yours make me so happy.
<p>My wife and I made this concoction about 6 weeks ago. We applied it to all the outlets and wall switches, bottoms of appliances, back of stove and fridge, all drawers, and every corner of every cabinet front and back. I was doubtful that it was working when on day 4 PA ( post application) I was still seeing them in the early AM when I was up to go to work. On day 6 PA I woke to only see about 4, which was an improvement over the 30 I would normally see. In the following days I had only seen one or two stragglers in our kitchen which is where the main concentration of them had been. It has been about 4 weeks since I have seen any in the kitchen. We are still seeing some in the living room occasionally. I am going to make some more up and put it in the bottom of our sectional, tv stand and the coffee table. We are seeing more in our bedroom and they are getting on us in bed and biting us. Not as frequently as before but it still happens. I sleep with a fan on and anytime a hair gets blown by the fan I jump up and smack the area until I could be accused of self abuse. Paranoia has set in but they will be gone soon completely!!!! This stuff definitely works!!! Thank you for posting this!!!!</p>
Hi ScottS75, you are welcome but it's a wonder to me why you have any at all. Did you foam any places they might be coming in? Did you do ALL the outlets in the whole house? Is there anything you might have missed? Thank you for writing.
What if we don't have an attic , and how do you bait the electrical outlets
It doesn't matter if you don't have an attic. See step #7 for outlets.
<p>First I haven't tried this yet, but I am going to. My house is clean, but I have to have books, boxes of tools, computer parts, wood working projects, ect. My roaches BITE! me. I used a roach bomb (two boxes of them) and when I came home some were dead, but lots were standing around to welcome me back and thumb their noses at me! (We're still here!) I can't wait till winter to freeze them dead, so I'll let you know what happens. Thanks for this 'ible'.</p>
It's true about the biting. My uncle woke up once when he felt pain in his big toe and a giant roach was on it and it had bitten him.
If they are biting I dont think they are roaches. They might be bed bugs.
Don't take this wrong, I know what a roach looks like. Google it. Roaches will bite a human living or dead.
Alright no worries, didnt know that. Never experienced it or heard of it and I've lived in a big city all my life is all.
I'm on my way to the store to buy the ingredients inyour recipe today! We live in an apt building and area with lots of low income people who dont seem to care much about the conditions of their own places so I think we are facing a big challenge because there will always be roaches in the building. Unfortunately this place is our only option for the time being so hopefully we can keep their numbers down in our own unit. In our favor is that our place is small small with few outlets and water entrance areas so hopefully it won't take too long to do the baiting and sealing. Great tip about behind picture frames too! I will absolutely be in utilizing the tips for moving when we get to that point, hopefully in the not too distant future. After reading this and many of the comments I'm feeling more confident about the battle we have ahead of us...thank you
Thank you for all the information and tips. I just got finished baiting and followed all your instructions and im hopeful it'll work soon. Please help, what did you do in your kitchen meanwhile you got rid of the roaches. I know to keep everything sealed in airtight containers but what about the dishes, pots, glasses, etc.. did you wash them out before each use.. i know it maybe be an obvious answer but I've never had roaches before... anyone... please help..
We are currently experiencing a problem with these little f*&amp;#! as well and so we've been cleaning everything before we use it. It's a pain in the butt, but better than take the chance of eating off of things with dirty roach tracks and who knows what they bring along with them. I'm going to the store today to buy supplies for this instructable, I really hope it helps us.
ok so i did the kayro/corn syrup,floor and boric acid mix and laid it in cabints, under sinks, closets, corners, behind fridge and stove and things like that. i also laid the boric acid on the floor behind dressers and stuff the kids cant reach ive did all this 3 days ago and im still seeing them. how long could this take to start seeing a differance
<p>Hey AmandaK16, sorry I missed your comment and it's been 5 days since you wrote - this should take only a day to see a difference. But you may be dealing with Germans which live inside and are hard to get rid of. If this is the case you need to find out where they are living and vacuum like every day. I noticed that you did not mention putting the bait in the outlets and this is the MOST important spot 'cause they live in the walls - the regular ones. We I mean they travel through the walls, all of them. Anyway get some bait inside your walls.</p>
Hi I came across your post in search for help. I started baiting and sealing last night wasn't able to finish but will get to it again right after work. My question is.. what do you do with your dishes, things that get used daily.. like plates, cups, spoon.. etc. When you're going to use them? Do you wash before each use? I just moved into this house, and turns out it has roaches! I have all my dishes still in boxes and I don't know if I can put them in the cabinets because I don't want the nasty roaches to crawl all over them, but we can't keep them in boxes for ever. I've never had roaches and I'm freaking out.. I stay up at night killing them and then up early the next morning cleaning where I think they've been. My kitchen cabinets are empty and I moved all the boxes of dishes outside for now. Please help. I will follow your introductions for baiting... but need more help with what to do with the stuff we use everyday in the kitchen. I will appreciate your help.
<p>YD1, I think that you can put your glasses in your cupboards, if there is no food there the roaches won't be in there. I know you are freaked out right now but seriously this gets better every day. Read a few hundred comments and you will see that you are not alone and that this does work. Also they are very entertaining.</p>
<p>Quick question - will this work for Oriental roaches? I believe that is what we have, as I only ever see these beasts in the bathtub, near the sink cabinet in the kitchen and near our shower. We have a creek that runs behind our house, which will often flood underground and into the yards around us, plus our crawlspace is very damp and the entrance to it is from the outside. I'm freaking out because our landlord refuses to send an exterminator, and when I called for one, they want $200 up front for a one time treatment and then $150 for subsequent, 2 week treatments. We live on a tight budget, so anything homemade will have to be the way to go.</p><p>Also - how do I treat the crawlspace with this stuff? I wouldn't know where to put it, or even if we can't fit under the house to properly apply it. I have also spoken with the landlord about drying the crawlspace out and putting in a sump pump, but she isn't willing to do this for us, as the cost is too much. </p><p>Moving is not an option, as my son needs to be in the school district we're in to get Title 1 services for his disabilities, so I'm just trying to figure out ways to keep us from having to leave our home.</p>
KatC6, First of all you have rights as renters - did you know that by law you have to have screens for your windows? It's a law and you can find out more when you look up your city's building codes. I found this out while building a home and I didn't want screens but I was required to buy them because of this law. When I complained to the city they told that I would probably get one of their blind inspectors so not to worry about it. I asked why in the world there was this law and found out it is mainly for fair housing for renters. If you are living with mold (hey, it's damp so it's got to have mold) from the crawl space I think you might have the law on your side. Just a thought.<br><br>OK, so on to your oriental roaches. I don't know but I think so from the comments I have gotten. Good luck, stay in touch so we will all know if this works for the orientals.
<p>I'm going to start with sealing up the holes first. I literally just opened the closet in my sewing room, looking for needles and noticed a cool breeze coming in. I NEVER noticed it before, but this is the wall that is on the backside of our full bath, where the pipes are. I bent down and found a 12 in x 12 in square hole in the wall!!!! I assume it is so you can get to the pipes easier, but dang! My cat could fit through there if I ever left the door open! That thing will be sealed up, pronto.</p><p>I will let you know how and if the paste works on the bugs we have. </p>
<p>Feeling for a breeze is a great way to feel if there is space to be sealed up - in your case that is crazy but at least you found it!</p>
Hi, this is a great article and hopefully it helps me! I just moved into a new apartment. Everything seemed fine until my first night when all the roaches came out. Im going to try your method but had a question; after some investigating I may not be able to seal everything in the apartment (most but not all). Will this be an issue or should your method be as successful?
Kaichil, if you read the comments, one that is the longest goes into some detail about how this did not work until all the holes were sealed up. I know not everything is possible to seal in many cases and I think it just depends on how bad your infestation is but I am sure it will work anyway, just maybe it will take a few days instead of right away.
My fianc&eacute; decided to move me into his aunts old house. She didn't take care of it, I knew that be he neglected to tell me that our new house was infested with roaches. My biggest fear!! We tried bombing three times and didn't work. I have spent money on pesticides and traps and nothing seems to help. I found a group behind the fridge so I thought maybe that was the nest. Growing up we never had roaches. I am a germaphob and I love to clean. It has to be cleaned a certain way or it is not clean. Anyway behind the fridge I tried cleaning this so called nest but even after I did they were still all over. Is it possible that there could be more than one nest. I mean not only is there roaches everywhere but there's roach crap everywhere too. And it's not coming off the walls is there a tip for that too?
Kjandrews5294, I'm sorry, I just don't know. I guess it is possible. I know it is important to get the marks off of the walls but I don't know what to suggest. I am sure that if you are a germaphobe like I am as well, that very soon that house will be free of roaches. Just keep at it. Especially seal up all accesses for roaches to get into the house.
<p>online amazon says discontinued by manufacture. the probably threatened the guy for putting folks out of business</p>
<p>THANK YOU so much! I had tried professions and then some organic ways and I had almost given up. I tried this 6 days ago and I am blown away at the difference! I am SOOOO close to a roach free home. Thanks again!</p>
Wonderful! Thanks for writing.
<p>Any advice on clean-up? I was a little zealous as I was tired of the infestation and actually put the product all up and down the piping instead on the rim of the connection as displayed in the graphics supplied.</p><p>I think I will actually have to go in and wipe down the stuff off the piping to keep myself safe. Any advice on how to remove both the paste before and after it has dried up. </p><p>I hope that my zealousness pays off.</p>
I don't think it matters. I think you can clean it up with hot water.
ok so ive laid this mix all over my house and ive bombed twice. now im seeing babies but also big and medium sized ones. ive noticed they like to be behind my fridge and my hot water heater that are right next to eachother. i have to babies. its grossing me out. was watching the game and one crawled on the entertanment center while watching. then the babies was eatting on a slug that had gotten in the back door. i sprayed them with bug spray. ive been out my home for a week from bombing and cleaning. i dont have washer in dryer hook up so washing everythibg has been crazy. i just want to go home in not see these things. any other sudgetions
Dear AmandaK16, You should see a difference right away - in my case the exterminators got rid of the major population and THEN baited. But you have bombed twice and put the bait everywhere - just make sure that the bait is their only food source, vacuum constantly for egg cases, feces, roaches, food bits etc.<br><br>I know that this is horrible, simple horrible to live with. It's a war and every day will get better but every day you must improve the situation, clean clean clean, vac, vac, vac, I understand how much of a downer this all is, especially when you have to drive to the washer and dryer.<br><br>Read a few hundred comments, you are not alone, you will find out ingenious ways that they get into your home. But you are going to be OK. The boric acid on the floor won't really do much and it's a bit of a contradiction to how my bait works. But do what you think is best. Keep in touch, please.
<p>Hi, thanks for this great recipe!! going to buy these ingredients today and get started and I can totally see why this will work.</p>
It's obvious. You read the whole thing. I appreciate that.
How often should i repeat putting this paste on? I know they hatch eggs like every month?
It's good for at least two years.
Thank you so much for sharing this! We thought we had gotten rid of our roach problem but they are back, and I'm losing sleep over it... again.<br><br>I just ordered some boric acid and can't wait to try your formula. Will update you on our results in a couple of weeks! Thank you again :-)
