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 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

Picture of What you will need
maple syrup pour.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.

Oh Tasha-calderon I am so happy you took the time to write - thank you so much for your wonderful words. I have had the worst day and this has made me so happy. I am sending you a virtual hug!
I cannot thank you enough. Me & my children live in a clean roach free home. You have made our place into a home. I am forever grateful! Thank you again!
Ninzerbean (author)  Tasha_calderon1 month ago

Dear Tasha, I know, I understand, I've been there - house into a home sort of thing. It's why, you are why, I wrote this Instructable. To turn houses into homes. I will be forever grateful for your comment.

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)


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.


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.


Ninzerbean (author)  Dseg15122 months ago
Dear Dseg1512,
Thank you for taking the time to write. Comments like yours make me so happy.
Im starting to feel like there is hope and then I read further into the comments that this technique might not work for german roaches... Please help!! I dont know what to do. I have a newborn and moved into this roach infested place shortly after. I didnt know this house was infested like this until the second day of moving. Now theyre in my stuff. Im stuck. I dont know what to do. Please help!! My depression had gotten so bad, I sit here and just cry.
Ninzerbean (author)  Ninergirl9513 days ago
Ninergirl951, I got a comment today that was all about success with German roaches - so don't be sad. Go read it. Go get the stuff, bait, you will be fine very soon. You might be sad because you have a new baby so you probably are sleep deprived which can make everything seem very difficult. But first things first, you are going to get rid of the roaches. Then you will feel great. Really.
Ninzerbean, thank you for your quick response and your encouragement. My husband baited this place according to the instructions. We spent hours doing so. One if my conserns was baiting the rooms, since I had not seen any in the rooms. I felt that by doing so, we would be sort of calling them there to the bait. Well, last night the exact thing happened... I saw one in the baby's room on her dresser and after breaking down just at the thought that they are in my child's things, I went to my room and there was one creeping around on my dresser. What is happening? Is this normal? Or have they just started to invade the other rooms in the house (they were consentrated in the kitchen and bathroom only). Please help me!!
Ninzerbean (author)  Ninergirl951yesterday

Ninergirl951, My guess would be that roaches were already there, even though you did not see them before. The bait does NOT attract them if they were not there before. They live inside the walls so rooms mean nothing to them, they are flowing all through your home on the inside of the walls. That is why I urge people to bait the whole house and not just where they see roaches. You only want to give them one source of food to eat - obviously you are being vigilant on vacuuming and keeping the house super clean.

Some people see a rise in activity after baiting as the roaches search for a food that is not going to kill them, this should go away soon though. Keep vacuuming, getting rid of cardboard, foam up your spaces to the walls under the sinks etc. Keep in touch.

Just came across this and look forward to trying it out... Gotta say I am a little jealous those little effers get maple syrup. Stuff's expensive!
Ninzerbean (author)  FaithF2 days ago
Very expensive - just use Kayro syrup, or cheap pancake syrup.

Thank you so much for not posting a photo of a real roach! It makes the information you gave so much more easy to read!

Ninzerbean (author)  YuriE14 days ago
Ha! You are the first to say so. Obviously you and I are in the same camp.

Definitely :) I will come back here to let you know how the bait worked for our situation too (German roaches in a townhouse).

I never leave reviews UNLESS something is amazing and will help someone else in a positive way. This stuff is amazing and all that is needed for a roach infestation. Our town home was crawling with german roaches and I noticed them as soon as we moved in. I immediately found this recipe and made it that day. I followed every step. Over a 5 day period after baiting, our home went from infested to 1 or 2 roaches. And within a few more days and now 6 months later ZERO! I am making the bate for neighbors who ask if we have roaches....as a gift. Thank you for sharing your recipe! !!
Me and my fiance just moved into a townhouse last week. We have moved our stuff but not us and the kids because we have discovered an infestation of german roaches. He bombed, did home defense, boric acid, we made this paste and put it everywhere. I ran out and finished the house with peanut butter and boric acid. We went to work on it last night, and there were WAY more roaches everywhere.... it freaked me out. Are they coming out because the bait? I mean they are all coming out now. And how long till they start to die from this paste?
Ninzerbean (author)  Bktexas24244 days ago
Bktexas2424, Wow, what great news! I'm so happy for you, especially because you had the Germans and you were successful. They are so hard to get rid of I hear. Whoopee! After 6 months the fact that you came back to say thank you is really nice - thank you.

Where is the best.place to look for the roach nest? Do you have a photo of one?
Ninzerbean (author)  1920ces4 days ago
Do I have a photo of a roach nest? Did you read the first step of this Instructable? No, obviously not. I would normally take this opportunity to repeat the same things I say in most of my comments, which is a repeat of what I write about in the Instructable, but this time I am not going to do that. I'm just not in the mood.

I do want to help you of course, so just read a few hundred comments. That will tell you what you need to know about finding where the colony might be living.

I'm sorry for being snarky but hey, I do my part, I answer questions, I stay up to date monitoring this 'ible - now YOU have to do your part and read it.
I HAVE done my part and read your article several times and a lot of the comments. It is the best advice I have found on this problem.

I appreciate you responding in a timely manner as many other
sites seem to take questions into some black hole.

I apologiize if you think I was asking stupid questions and insulted you.

I am recently single so I am new to handling these types if problems.

Ninzerbean (author)  1920ces4 days ago

OK 1920ces, being recently single does kill a lot of brain cells, you get a pass on this one. If you think that you have German roaches they are harder to get rid of because they live inside vs the big ugly ones that have a colony outside. If this is the case you need to do a good job to decimate the population before or at the same time as baiting so that you have faster results. They like to live in appliances - anything that is plugged in and warm, such as a microwave, an oven, a game player like a PS3 type thing. A lot of my readers tell me about how they rue the day they bought a used "fill in the blank" and later on find out it is infested.

So a nest would be a gross swarming freaking amount of roaches living in one place - if I can't even bare to see a photo of a roach there is no way in the world I am ever going to post a picture of zillions of them in one place - see what I mean? And don't you dare either, I have super powers here and can delete comments.

Hope that helps.

Will borax work the same way as boric acid?

Is it weird that i keep reading this article over and over to comfort myself!?..my husband is at home trying out this method as i type..because as soon as i found this article i had him on a mission! This article gives me hope, thank you for taking the time out to write this..i am praying that this works!! I will comment back real soon!
Ninzerbean (author)  MichellV4 days ago
Hi MichellV, I think that there is a lot of comfort in knowing that you are not alone - no matter if it's a fear of roaches, or just knowing that other people have them and sometimes worse than you do. It also helps to read what other people have tried.

Anyway, it's all very interesting - here I am so afraid of the things and yet I've spent 6 years answering at least 3 questions a week about them. More than one million people have read this 'ible, amazing. My mom calls me the 'Roach Coach'.

But, hey, this will all be a distant memory very soon. You have a good husband - go give him a kiss.
kmarnz6 days ago
Thank you!!!! I cleaned my house thoroughly, and baited the whole apartment according to your instructions, and then sprinkled boric acid on the ground and other areas for a few days. It was terrible in my apartment a few weeks ago. 2 weeks later and I am almost bug free! I still see one every once in a while but this made a huge difference!

Hi ninzerbean. I am 15 yrs old and get SUUUPER depressed whenever i see one. I never even like talking about them so i have a little courage tonight lol. It is wet summer here in florida and ive seen ATLEAST one every week since mid june. They are usually midsized. I keep telling my mom how much it bothers me but she swears that they are just comming in through open doors and drains, and that just spraying raid around the doors and closing drains is enough. Obviously not. I get major anxiety when im home alone at night and see one. I have to kill it with no comfort or support. I literally sleep right next to a can of raid every night just in case and walk to the bathroom with it. She said she'll get some roach traps in the morning but something is telling me that that wont work. She is too calm about the situation and not phased. Last night i heard her shout!! downstairs because a roach was on her hip on the couch. I came downstairs and she told me and was like "its dead now" trying to play it off. I told her i would have died literally if that was me. Its not like she doesnt care because she wants them gone just as much as i do, but she isnt nearly as "passionant" as i am about it lol. Any that i see is about the same size as the last one. Im going to tell mom about this remedy and hopefully she doesnt (but most likely will) blow this off. I saw one outside my room an hour ago ( my bedside raid came in handy?) and am basically typing this and reading comments for moral support since my mom who usually gives me that support is at work
right now. She always comforts me but just because its not an "infestation" she tries to downplay an experience with one like its normal. I feel i shouldnt have to live with a fear of even going to the bathroom at night because of a bug. I cant convince her that just because we dont see 12 a day doesnt mean that we dont have a problem on our hands. Thanks for reading my long comment int advance.lol
Ninzerbean (author)  Skyy0110 days ago
Dear Skyy01, I was once you - my mom moved me to Florida from NJ when I turned 14. I had never seen a roach before then. I was so afraid of them and my mom might have been as well but she did a good job of pretending she was not. It's possible that your mom knows that extermanators don't do much good and she doesn't want to waste money. If only you could show her this Instructable, it only costs a few dollars, probably less than $5 to find all this stuff, a lot of folks have found boric acid powder at the dollar store. I know Ace Hardware in Ft Lauderdale used to carry it. But once you have the boric acid powder the two other ingredients are so easy to find, you can use pancake syrup or Karyo syrup which is cheaper but you might have the pancake syrup already.

I guess the larger problem here is that you mom does not take your very real fears seriously. That has to be job one then. Sit her down, show her that you actually wrote to a total stranger about this, that she HAS to take your fear seriously. It's like a phobia for me, I scream so loud and it's not like I can help myself. I scream and it's only me in the house so it's not like I am faking it and putting on a show for laughs.

Good luck, and please keep in touch so I know you have fixed this situation. I really know what you are going through.
Ha. Totally a phobia for me. I get it from my aunt. She left her whole house last month to stay at my grandmother's because she saw a pregnant spider. Didnt even kill it. Lol. Just packed and left. Its only a few hours after you replied and surprisingly she is going to give this a chance. I had to butter her up a bit cus she was like no no no in fear that syrup would draw the attention of ants. Will it? If not, great. I think the selling point to my mom was when i said it lasts for more than 2 years. She took a long pause and was like "........how long?" XD i think we"ll try this tomorrow. Ill give you an update. Also, i do want to ask if you dont mind, i do believe that these are water roaches btw, since it is a kind of rarity that we see them, and i have my phobia, i instantly want to kill them if i see them because i dont want them near my room/refuge. How will i know if the roach that i see will even go for the bait instead of my bedsheet if i let it live? Is the bait strong enough to be detected from a decent range from the roach? And will this attract ants? Do (possible) water roaches even like sweets like syrup? Thank you so much for your time.
Ninzerbean (author)  Skyy019 days ago

Hi Skyy01, This stuff is great for ants! It does not attract them but if you put it where they are - along their little line, you won't have ants anymore. As for waterbugs/roaches, I don't know, I don't want to know, I have no idea what they are and I do NOT want to be enlightened. But as to the attraction to beds vs bait, you just have to read the whole 'ible again. There is a whole whacked idea I have that roaches live in a colony and they communicate to each other not unlike bees. Once they eat the bait they will tell each other not to go to the house with the stuff that kills them. They live in the walls, so when you see one he is looking for food, not just taking a stroll. The colony is outside though. That is not the case for German roaches - they live inside. Anyway, just read the whole 'ible one more time, read some hundred or so comments and you will see the big picture. Stay in touch - I am thrilled that you got your mom on board. You are not the first kid to write to me and then gets the parent to do the baiting.

Hi ninzerbean. It hasnt been too long but i cannot believe that i havent seen a single roach thus whole week. This really worked. We put it in the loundry room, garage, ac unit, all the sinks, and water heater. The next day, we saw about 5 dead roaches. This worked sooooo well. I am so happy. Thank you soooooo much.

Hi, for the past few weeks walking into my apt has been a nightmare! Im afraid to touch things and i literally just want to cry. My 2 yr old,my husband and i moved into our apt, and for the first month or two all was clear.. Slowly but surely i started seeing more and more..now they just dont stop its so depressing. We bombed the apt the other day, when we came back these roaches seemed to just be dancing around laughing at us. I lost it, i started doing research last night, and i ran into your great article, THANKS!!! WHEN MY HUSBAND GOT HOME FROM WORK I TOLD HIM WHAT TO DO, IM FORWARDING THE ARTICLE TO HIM..AND GOD WILLING I WILL HAVE THE SAME AWESOME RESULTS YOU DID! I WILL COMMENT BACK LATER. its very unnerving to have my two year old constantly saying " mom, theres a bug!" I just want our place back, and clean..

This may be long so I apologize in advance. I just got the keys to my apartment today. After my landlord left I noticed two dead baby roaches on the kitchen counter and I killed a medium sized one on the kitchen floor a little while later, as well as a baby one on the living room wall. One baby had even gotten onto my phone charger cord. I'm semi terrified of roaches, simply because they make me paranoid and feel very unclean, so I get fidgety... I'm just not one for bugs in general. I really want to try your method, so my question is how do I smear it and exactly where. I read the steps and I'm sure that my landlord wouldn't want me cauking the place, so I want to try to accomplish extermination by placing the paste only. How do I smear it? Do I go along the entire molding of doorways or do I place a glob of it at each end? Do I open up outlets and light switches and just place a glob of it or should I smear it along the top, bottom, and sides or just along the thing that I take off? Also, would it be good to place some in this vent thing for the AC? Also, in the kitchen, where exactly does the paste go within the cabinets and should it be smeared there as well I'd just in a glob? I've already brought my belongings in but I just liked them up in one room because I actually want my landlord to have an exterminator come before I employ your method, just to be extra cautious because I'm not from here, nor am I used to roaches, so I'm easily frightened! Also, if you have anymore tips as to the placement of the paste, please don't hesitate to share! I welcome everything! My father told me to get some powder and put down in the kitchen, which in guessing is the acid you've mentioned, but I just want to be sure that they're gone. Even though I've only saw a few, I'm kinda scared to sleep here tonight! Help me please!
Ninzerbean (author)  Char'DeW8 days ago
Char'DeW, Maybe you might want to go back and re-read the whole instructable, especially step 7. All the answers to your questions are in the 'ible so I would just be repeating myself here. It is possible you are looking at the 'ible on a phone and can't see the whole thing or make the photos large like you would be able to do on a computer?

I think it is a good idea to have the landlord come back with an exterminator before you put your stuff out. It sounds like you have a serious problem if those roaches were out in broad day light. There might be a nest in one of the appliances. Be sure to be there when the exterminator comes so he or she can pull back the fridge or stove to look for a nest.
The exterminator is in route to my apartment. As for the appliances, my landlord had a new fridge and stove put in yesterday. Yes, I'm viewing this all on my phone because I haven't had the internet installed in the apartment yet either. At first glance there doesn't even appear to be any in the apartment because my landlord said that he didn't even see any when they were prepping the space for me to move in... Now, how honest he was being is between him and God. All I know is that throughout last night I killed a few baby roaches and I know that if there are babies, there's a momma and a daddy somewhere. The question is where, because before the stove and fridge were installed I didn't see a nest anywhere! Thanks for all your help. You don't know how disturbed roaches make me, I couldn't even sleep last night and I was close to just sleeping in my vehicle. I shook all of my stuff out and put it back in my truck until I figure this out! Thank you again!
