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
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.

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_calderon2 months 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.

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!

I just moved to a state from one where these demons are really not an issue. My family needed a change and be able to explore grow and see beautiful things but we got this apt and it seems to b infested with at least 2 kinds of roaches!! I have never dealt with them my whole life. We cant just up and move and as mentioned above they would only come with me neways. I am freaking out... I am a very clean person. One might say close to a perfectionist even a lil ocd. I sweep n mop with bleach i tried sprays and otc baits or roach "motels" and the roaches just r only getting worse. The apts manager sent me n exterminator, as said above also he helps zero :( i have been here for bout a month. I barely slept since, been 2 the hospital twice cuz i cant eat or sleep n get headaches from being malnutrition and dehydration. I wont drink outta the cups without washing and keeping uo with 3 lil 1s i just dont have time to do that for myself and end up skipping it to do the extra tending so they have it. no joke I've lost 35 pounds since. In 1 month!! I am so grossed out i cant eat this coupled with anxiety n level if ick stress this is causing makes my whole body hurt. I am absolutely miserable! The only thing i manage is fighting roaches. N i cry omg do i cry. I cant take anymore!! I want to have to win this fight so bad and i want to make sure i do it all correct but also safe for my babies. Do you know if this substance is safe if kids find it? Also i dont have any flour and am so determined to get started on this i cant just sit here n wait to try this til i can get some. Would bisquik work you think? Or does any1 no if the peanut butter actually worked? Also the fridge, stove, dishwasher (which seems to accumalate the most of them inside and out!) where do i put the stuff inside as u say? Like where do i take the whole things apart? I have to fight these things. I'm sorry if I'm being dramatic but they r so gross and relentless. I am so emotionally and physically exhausted. Your instructable and response have given me hope. It says above that its worked for every person who wrote. Even in apts and with large infestations. Its the only thing i found that has ALL positive feedback and is somthing i havent tried. I cant get to a store for at leastv1o hours thats when i will get all the sealing stuff but i wanna start smearing this stuff n cleaning until til then I will be checking this thing like every hour or else i will hav to wait another day til i can get flour 2 do it exactly as it says. If bisquik would work i can start this treatment soon as naptime! lol this recipe has to save me. There seems to be nothing else.
Thank you and wish me luck
Ninzerbean (author)  kosnopfal15 days ago
Hi Kosnopfal, I think Bisquick will work just fine. For where to put it see step #7, you are going to be putting it in places where no one is going to see it, much less get to it. Pull out the kitchen drawers far enough to put a dab behind them. The bait sticks to most surfaces and that is why it is so easy to use, you can place it on vertical surfaces that are out out sight. It takes time to do it all over, but don't skip any places. Do your WHOLE appt., not just where you see them. And stop cleaning with bleach - it's not good for you or the kids. Your vacuum should be your best friend right now, not bleach.

I don't know where you read that this method works for everyone, I can't say that, everyone's situation is different. Not everyone is willing to do all the work this takes. This is a war, you have to take all the steps - like sealing up cracks and spaces where a bug with no bones can slip though, with expandable foam. Good luck, keep me posted.

I know how depressing this can be, but soon this will be a distant memory. Each and every day this situation will get better, try to enlist your neighbors to do the same thing. If one apartment has roaches and the other apartments in the building are not using this method, chances are that all of the apartments are affected.
Thank you for your responses u are an angel! From the feedback on your instructable most seemed to be positive and successful. I am gonna put it in as many of the out of sight spots i can find 2day and as soon as my husband gets off he is going to put it by the vents, outlet covers, and do the sealant stuff. We were wondering about the appliances. Do we take them apart 2 put it inside? What do you suggest i clean the floors with? I was told sum floor cleaners atrract them and that they dont like bleach ao that i just went with that cause I'm scared to attract them worse. Everyroom except the bedrooms is ceramic tile so it has to be washed with somthing on a daily basis. Any pointers?
Ninzerbean (author)  kosnopfal14 days ago

Hi Kosnopfal, I don't think you need to wash the floor every day. Vacuum it, but really, I don't think I have washed my own floors more than 4 times in the last 3 years. I don't like to wash them I guess, the kitchen floor gets washed more but still I think you do not need to daily mop the floor. But if you do, use something environmentally friendly, or hot water.

As far as the appliances - you probably have a nest or colony, get your vacuum ready. I don't think you need to bait the appliances, they are just a place that is nice and warm for your roaches to live, but they still need to go out and explore so no need to bait inside the appliance. If the heat of turning it on is not killing them you really have to wonder don't you?

We even did like boric acid bottle said n put it alll along the baseboards & cupboards. I seen sum walking right over it... Is that right? Did i do it wrong? Lol i feel like i did like a voodoo sayonce ritual like when the surround their home with salt but with acid lmao. My mom called n my husband says she cant talkt shevis dropping acid in the bedroom lol

kosnopfal, I went thru the same thing years ago when my Son was only a few months old, I had never seen nor been exposed to such disgust,. I was up all night every day fighting like 6 different kind of roaches. About using the boric acid, u have to make sure you don't make plumes of dust from it- it is a gentle process, when applying into cracks, baseboards, gently pour some borax acid on floor, then with a paint brush, gently brush it into crevices etc. the thing is your appliances. You see alot of times they hide in your toasters, microwave, all electronics. YOU HAVE TO WRAP THE APPLIANCE IN PLASTIC, AIRTIGHT. A GREAT TIME PERIOD WOULD BE 2 WEEKS IN THE SUN., IF POSSIBLE. Even stereos.! Im talking seriously. In that apt,. I lived at, at the crease where the ceiling meets the wall, is where they would nest. Quite GROSS! Well I made a paste of boric acid, flour, and some paint (same color as ypur wall) And its TEDIOUS but- you make it like a paste along the whole crease. it will harden, and if the roaches try to eat thru it. they DIE! Also on lids, under your refridge, under cabinets, use the sugar, and baking soda combo., Good Luck!

Ninzerbean (author)  kosnopfal12 days ago

kosnopfal, I am not a proponent of putting out boric acid powder. It's what some people do but it's not part of my system for reasons I describe in the 'ible. It does not teach them not to go to your house because it is not food that they eat and bring back to the colony or nest, they have to run in it to get it on them and it's just not what this whole system of mine is about. It can only be put on horizontal surfaces, it doesn't stick, you can't put it in out of the way places, and because you need to be vacuuming just about every day you will just vacuum it up.

Okay i did it... Took us 2 days but we got every crack, caulked the windows, sealed fridge & front door in2 the apt, put the goop EVERYWHERE, plugged all drain, even sealed off the dishwasher lol. So how long til i start seeing em dead? We r completely exhausted n so hungry we spent all our money 2 get decent cleaning supplies as we got here with nothing. I figured i could sweep carpet n wash floors with my hands but after these things we had 2 get pesticides, a vacuum, mop, good safe cleaning products etc. But omg we feel like we been up 4 days n r just so weak between kids, cleaning n the roach war we never stop but cant energize with no food or sleep i cant take nemore. I feel like a crackhead like the bastards r all over me or watching me waiting 2 come steal ne meal i may even think of lol We cant eat nething made here or they come out n appitite goes away immediately. Just tried 2 make lunch 4 the kids n out comes 1 from the stove. How long does it take til they die from the goop? Also i 4got 2 ask about vents, how do i keep them from coming in those? What does a colony or nest mean n what do i do 4 those?
Ninzerbean (author)  kosnopfal12 days ago

Kosnopfal, you should see results right away, within a day. The vents? Well take them off and put some bait up there. If they are coming in the vents then there must be a way they are getting into them, if you can't find out how then at least bait inside of them.

A colony or nest would be like a bee hive, thousands living together. If you find they are infested in your appliances or any electronic equipment then you have to try to get rid of them, like take a chunk out of the population and then you will see results from the baiting more quickly.

Well sealed and baited 2 the best of my ability neways... Less u can thinkbof nething else?

Cuz dishwasher is stuck we cant pull it out, we tried but my husband screwed it locked shut, put bait inside it b4 hand of course, then sealed around the outside with sum sealing product. N well baseboards and trim idk wut 2 do with those less i remove them completely, I'm thats a no no in and apt lol And cupboards. Short of taking them off i dont know how 2 c behind them. We did put seals around them and baited them as well but if there is a nest back there how would i get 2 it with out removing the whole cupboards...
O and i have horrid allergy problems in life and the past couple days i cant breathe... U said they cause allergies to flare? Do u know if regular allergy meds help 4 roach allergies? Lmao ya i dont i will asking a pharmacist THAT question any time soon! But my throat just burns like heck n I'm all stuffy...not fun. This has to stop. I just keep racking my brain... Thee only place a nest could b would b baseboards and trim, dishwasher or cupboards. All three are sealed and have bait, will that beat em if there is a nest, u think?
Hello ninzerbean! Ok so 2 days... I am so dum when it comes 2 these things lol i talked 2 my husband n he is the 1 who put it everywhere cuz i freak out. I watched from a distance as i cleaned and did the statanic boric acid ritual round thee whole apt. But he said he didnt c nething resembling a nest. U said like a bee hive , right? I would think that would have been noticeable cuz he pulled out all appliances n put the goop around them all in his process of everywhere even took sum covers off n looked and gooped inside even shook some up a bit. None even came falling out in fact we barely saw any while we were going crazy on this place. I even had him recheck the stove n fridge yesterday. So i dont think the nest if there is 1 is in there. U think they can nest in a dishwasher? Can 2 different kinds of roaches nest in the same item? As 4 the vents, we definately baited in and around those as well as its an apt and we figured they touched other apts vents in places we surely could never get to. Also i am wondering what seeing results would mean? I FEEL like i am seeing less but i am still seeing them... Is that normal? And it only seems 2 be the bigger ones. What about baseboards... Ne suggestions on how 2 seal or bait those? I heard they can nest in those. How long before i bring my crazy 2 my new landlord? Lol

o and sorry if my writing turned kinda text like. I hope its all easy to make sense of. I am horrible at talking in type lol

Thanks so much sharing! Thought I might add a little something for those who have basements...start applying all these steps in your basement first! Those nasty little critters will come into a basement without you even knowing it and infest your living space in nothing short of a nanosecond! This stuff really works!

Ninzerbean (author)  BeckyD45 days ago
Hi BeckyD4, it was just today that I was thinking of explaining that it is important to know how a house is built to understand where the monsters live and how they have egress to the whole house through the walls. Like the electricity lines. Thank you for your comment to help those with basements.

ectonas1238 days ago

Thank you SO much for posting. I really, really, really hope this works. I've tried just plain boric acid but once I think they're gone, I see another one. Yesterday night, I was frying some chicken around 6PM and one flew out from under the oven. I think our biggest problem is that we can't remove our oven/cabinets and they seem to be coming from there. I just had a couple of questions! After placing the bait in different locations, how long should I keep the bait there? When and how should I remove it?

Thank you so much!! I hope to respond once again after the appropriate time and hopefully I'll be sharing only good news.

Ninzerbean (author)  ectonas1238 days ago
Etonas123, once you place the bait, because you are putting it in such out of sight places, there is no need to remove it, it just stays there.

The roaches may be living in the area between your cabinets and the inside of the walls, try to find any way that they are being able to enter your home and block that up.

Hello there i was needing advise .. I have been leaving in my home for 4years and never had a problem with roaches .. latley i have seen maybe 3 to 4 everynight and varies from kitchen to bathroom but now they going to rooms . Its still 2 or less.. i believe its my neighbors or like I readed in one of your comments that it could be the dirt of the plants ??? I have a beautiful big Hiscubs plant right by my door outside you think this could be why im getting them? Or my dirty neighbors that i have seen with lots of their crap outside my side of my house .. Is there any way i could use this stuff you mention as a boundary between my home and theres so the roaches dont come to our side???
Ninzerbean (author)  sochil9 days ago
Sochil, the only thing I have heard of that may act like a barrier is diatomaceous earth. But I have my doubts that it will work this way for you and your situation. I think it's best to bait your house and make friends with your neighbors - like a challenge, I know it will be hard but you can do it. You could say something like 'Hey dirtbags, uh, I mean neighbors, I have roaches and I am worried that you might have them too, do you want to use this great bait to put around your house?

Anyway at least bait your own house and seal up any and all cracks with expandable foam to create a physical barrier to keep the roaches out.

Well obviously I hit the wrong button somewhere. Anyway... my wife and I did this today in our kitchen. Our former nasty dirty neighbor left us the gift of disgusting when she left. Hopefully this Roach Killer cocktail will work....fingers crossed. I will keep ya posted.

Hi I was hoping to do this to my apartment but I read over 300 of the comments but am still worried if it works because I recently used hard boiled egg yolk sugar and boric acid mixed to a play dough consistency put around my apartment. I am seeing more roaches but dont know if they are dying. If i use this solution, what exactly will happen to my apartment will i see alot come out and die within a couple of hours or just alot come out to eat it. Thank you

Ninzerbean (author)  MelvinN11 days ago
Hi MelvinN, Yes, I have read that too - that there is more activity after baiting, my theory is that the bugs are frantic and looking for a safe source of food. But it does work, you have to do all of the steps, get it inside of your walls, get rid of any actual infestations that are living in an appliance or some such thing.

As for what you will see - I do not know. I think some of what you will see depends on how bad the situation is.
Nida asad12 days ago
Hi, No, i added sugar and a lil water to make te flour thick and it was sticky when i pit that in kitchen cabinets and drawers, behind stove and refigrator...
Why i used sugar is that you have mentioned to make a syurp of sugar and water.. How do i make it? Rather than using raw sugar, should i make syrup By cooking it on stove to have thick consistency?
Thanks for ur quick reply :)
Ninzerbean (author)  Nida asad12 days ago
Nida, I can only respond to what you write, if you write that you used sugar instead of what I suggest in the 'ible, and I respond to that and THEN you tell me you added water... well whatever, but if (and again, I am only responding to what you have written) you tell me the places you have put the bait and then are complaining about it not working when I think I am so very clear that you have to bait your whole house, not just where you see them, that you have to get inside the walls via the switchplate covers and outlet covers and I post photos in step 7 of where to put the bait and you say that you have only baited the kitchen, well, it just is frustrating to me. If you do all the steps and it still does not work for you - that is the time to post your complaints. But not until then. I answer questions on this 'ible almost every day, I don't do it for money, I do it to be nice. If my way does not work for you please let everyone know, but not until you do it the way I have outlined.

If you are viewing the 'ible on a phone, I can understand that what you see is limited so forgive my frustration. It is just that sort of day for me.
Nida asad12 days ago
Also , one more thing, if i have to make syrup with sugar, ehat would be the quantity of sugar?
Ninzerbean (author)  Nida asad12 days ago
This is not the best solution - making a simple syrup (which is an actual thing and is very google-able) 'cause it actually costs more to make then just buying Kayro or using fake maple syrup (also known as pancake syrup) or that sort of thing. It is also not as syrup-y. But here you go: equal parts water and sugar boiled until sugar dissolves.

Hello! First, I want to say THANK YOU SO MUCH! This has given me so much hope. Here is my story: I just moved to sunny southern California from Nebraska. I moved all my belongings in a moving POD in cardboard boxes. When my stuff arrived I noticed it was very dirty in the POD and it had been sitting in a storage locker until I found an apartment. I moved in and the FIRST night I saw a roach. I freaked out, I am a very clean person and hate bugs. So I called the apartment company and they sent "their person on contract" out to spray (a week later of course). I was skeptical so I put down Combat roach baits and kept everything dry, clean and all food put away/sealed up. So while I was definitely seeing less roaches I was still seeing 1 or 2 only at night (at first it was 3-4). Then I found your 'ible. Two days ago I sealed up as many cracks and I could and tonight my roommate and I made your bait and put it EVERYWHERE! I can't wait to see if it works. I think we have the german ones, they are small grayish brown. I think they are coming from the water heater in the kitchen. I tried killing the nest but I can't exactly get INTO the water heater. It is in a small cabinet so I can't really get in there either. I tried to vacuum it out but I'm not sure how much good it did. They might be in the dishwasher because it is next to it. I hope I didn't bring them in from the moving POD but I don't think that is the case. Either way I'm never doing that again.
A few questions:

1: I accidentally added too much flour so it was more equal parts flour and boric acid. Will it still work?
2: How do I get them out of the water heater to kill the nest?
3: Do you think its fair I ask my apartment company to sent someone out to clean behind it and the dishwasher since they were here when I got here?

I really appreciate any feedback you have. I wish I could move but my roommate and I signed a one year lease and we are both broke graduate students we start school this week. I also found out after moving in the apartment complex is a big "party place" for all the undergrads at our school (lots of spilled beer) there is probably nothing we can do about it :( I keep trying to be positive and reminding myself of what you say in the comments, "So many people have it so much worse than me in the world" It is true. I have a roof over my head and food to eat and clean water, I should be happy. But i have been crying every single day, I'm at my wits end. This was suppose to be a fresh start and a new chance and I feel like I'm living in my nightmare. Please help! THANK YOU!

Ninzerbean (author)  livvy8812 days ago
Hi Iivvy88, I know how you feel, really. But first of all you have done a great job of investigating and you seem to have found out where the roaches are so go back to the landlord and request that the water heater and dishwasher be inspected and the issue resolved. You live in a world of social media having so much power - the power to post photos of what you are seeing attached to the name of the apartment complex and owner will go along way. I think you might want to talk with a lawyer first though. I know you are broke but as a grad student you must know someone in law school right? And of course this is only as a last resort, you of course you will want to hint about this action you are going to take when you talk to the apartment manager person. Be as nice and sweet as pie though. You have to deal with this person for a whole year and you don't want to do anything but be super nice. How about bringing cookies to this person even? This is not a problem that can't be solved.
Besides that, you are now armed with knowledge about apartment living and your next one will be inspected (and sometimes that does not help) and maybe something about roaches added to the lease.
I think your mixture will be just fine. But if you are not sure, just mix up another batch. Sealing up the cracks will help so much - but your biggest issue is the water heater and dishwasher - they may be living in the insulation and that has to be resolved. Take photos - they are worth a ton of tears when you are talking to someone in charge.
If they send out another exterminator, don't mention what you are doing on your own, they will tell you it does not work because they don't want to be put out of business. Just don't even bother trying to talk sense to them. They have become as programmed and well trained as the bugs.

Stay in touch and let us all know how this proceeds with the apartment company, also you may not need them after you bait anyway. Just be sure to put it everywhere and vacuum as much as possible.
Nida asad12 days ago
Hi,
I made the bait with 4 tbsp boric acid, 2 tbsp wheat flour and 1 tbsp sugar.. One day passed but roaches didnt even taste it .. And there are no dead roaches too!! .. Whats gone wrong ??
Ninzerbean (author)  Nida asad12 days ago
Well for starters you made a powder with those ingredients. It has little to do with my 'ible for making a paste that can be applied to vertical surfaces and put behind drawers and on top of doors etc. I don't know where you put it or why you used sugar instead of syrup. I don't think that is going to work.
