Instructables
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.

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 or maple syrup or pancake syrup
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 rice flour
enough Karo syrup to make a peanut butter like 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 too 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 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.

*(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).

Step 2: What my kitchen used to look like

Picture of What my kitchen used to look like
For every roach you see there are probably 100 hiding in the walls. If you see a roach in the daytime it means you have such an infestation that they are crowding each other out of their hiding places. Did I say gross?

Step 3: What my kitchen looks like now

I was so excited to buy this product and get started on my road to clean happiness! !
But when I went to our local HARDWARE STORE they tell me ROACH PRUFE HAS BEEN DISCONTINUED! !!
What? !?
Everywhere? Probably worked TOO good and was putting Exterminator businesses OUT OF BUSINESS, is my guess.
So now please tell me. Will another brand of BORAC ACID WORK? This bottle says 100 percent, no coloring nor scents. I cannot live like this. It's exhausting to be bleaching DAY and NIGHT, be on top of everyone who comes into my apartment AND it's so embarrassing! ! Somebody HELP ME!

I'm sooo desperate to get rid of these filthy roaches that when I couldn't find Roach Prufe i bought some other brand that says it's 100 0/0 BORIC ACID. PLEASE tell me if I follow all steps to this recipe I too can be rid if these nasty roaches FOREVER! !
I bought 2 bottles and am going to make enough for ALL 8 (2 bedroom) apartments. Other wise I think theyd never REALLY. Go away, right?
I'm on my way home now to try this and I gotta tell you, I'm excited! !
I just moved in with my 9 year old grandson and it's ridiculous how I have to bleach morning noon and. Night!!

BTW, we do not see signs of roaches inside our house. We use Ortho Home Defense from Lowes on the base of the exterior and interior walls every few months and have been lucky not to have a problem...or so I thought!

Sounds like your potion is effective and has helped so many people...kudos! I came across your Instructable after I found roaches under my house living on the fiberglass insulation between the floor joists. We had a small flood in our kitchen, and in order to dry our wood floors I went under the house to see if the insulation was wet. It was, so I pulled it all down and found live roaches living happily on top of the insulation. I know the water must be the attraction for them, but if we only had the water problem for a couple of weeks, I wonder if the roaches were there before? We will replace the insulation that was wet, but I'm afraid that roaches may have gotten to the other insulation as well. ? Replacing all of the insulation will be costly and doesn't promise to solve the roach issue. My question...what would you do in this situation? Thanks!!!

I read all steps multiple times before even attempting to try this. I am like you, cannot even open an encyclopedia with a bug photo in it. My husband and I bought our home several years ago and it is surrounded by trees and near a pond. I have never seen a roach before moving here. The yard is polluted with them, they are under every rock. Ewwwe! We saw 2 inside before we moved in and then never saw any more for a few years. It appears that they come in through the basement. I do not see them often but, it has been mor frequent in the last few years. I would rather die than call an exterminator. We live in a rural area where everyone would talk & think that you were just filthy pigs. Not true. After exhausting every idea, I came upon your intstructible. First of all, may God bless you for trying to help others! I followed your instructions to the letter at the beginning of October 2014. Never saw any after the 23rd of October. Then all of a sudden, they are coming back. First, I found a few dead ones. That was ok. Dead is good! Now, I have seen 2 live ones crawling in my living room on 2 different occasions. Do I need to repeat the process? It absolutely worked for 3 months. No exceptions. Why are they back now? Have you experienced this, or has anyone else? I trust your responses because you really do know what you are talking about. Please help me.

I have a long trail of roach infestations in my lifetime. :( I am currently living in townhouse apartments that have a German Roach infestation. Needless to say, it is uncontrollable. I treat the apartment, but it does nothing to the amount that are in this entire building. After 3 long years in this horrid place, I am happy to say that I am moving to a HOUSE. A real house!

Only.... I'm not so happy anymore. We had seen the house initially and checked for roaches. Cabinets, sinks, stove, bathroom, refrigerator, top of closets and doors all clear! No feces and no roaches, dead or alive. We happily paid our security deposit and signed the 1 year lease! We have decided to leave behind all furniture except our mattress and dog crates, which we would clean and inspect very well before the move. Well, all was for not, my dear friends! We received the key and went to shampoo the carpets/clean over the house before moving anything in.... And behold!!! Roaches. A couple dead here.... A few babies there. And the fridge.... Pulled it out to a nest behind/in it. And they're German roaches! I wouldn't have expected anything else of course!

"Enough is enough! I'm sick and tired of these monkey fightin bugs in my monkey fightin life!" - edit of Samuel L. Jackson 'Snakes on a Plane'

^ Without the edits.... That's how I felt at this point. We brought this issue to the landlord immediately and showed him the fridge and other areas. He said he had never seen that many... maybe one or two babies here and there. *facepalm* When there are babies.... There are parents/adults. Common knowledge to mankind in general about all living species. Anyways, he agreed to have an exterminator come and treat the house. So a plus!

Only, anymore, that is only a temporary solution. I have witnessed that personally. So after the exterminator came (today), she said based on what she saw behind the fridge... It was a heavy infestation (yay!).

The house has been empty for 2 months which I hope has tamed them down some, and I plan on using this method to treat the entire house before moving anything over. Thank you for this informative and helpful post and all the wonderful comments! It means the world to people like me who can't seem to shake these disgusting bugs from my life! Wish me luck! ;)

Happy Baiting everyone!

Happy Baiting Kate! I am glad you read the comments, though there are more than 700 there is a lot of knowledge there. Good luck, after all you have been through you really deserve to live roach-free forever. Keep us posted on your progress. Has the fridge been removed/replaced? From what I have learned on here used fridges can be the source of many problems.
I unplugged the fridge immediately when I found the nest (It was running since the power was on) and pulled it away from the wall. It has been treated and about 50 dead ones fell out of it when I went in after the exterminator had left. I flushed all dead roaches down the toilet that I found to ensure any egg sacs were not going to hatch. We plan on replacing the fridge as soon as our finances permit! I will definitely post any results I have within a week or two. :)
Ninzerbean (author)  thumplover881 month ago

Be careful if you replace it with a used one. You are very brave, 50 roaches would have had me running down the road.

So an update is in need! I baited the entire house upon moving in 2 weeks ago and have seen only 3 roaches since! My husband and I have been very clean and DRY with the kitchen/bathroom and have kept our pet food bowls clean and sealed in with their food when it is not meal time. The fridge (which we have not replaced yet) has been roach free completely (have been daily checking 4-6 times) the entire 2 weeks.

I'm so happy I live in a home now that I can walk on the floors with no hesitation! My previous apartment was so bad you couldn't go barefoot without stepping on the hundreds of babies that stormed the kitchen floors at night. :(

I will be reapplying bait as needed and plan to do a total re-baiting every 6 months or so. Again, thanks for all the wonderful help and comments from everyone :)

Hi there! So I just moved in with my dad in Vegas. I understand the heat but it's dry? I don't know. Anyways, there's the German cockroaches that came in with used furniture. A armoire and a used TV that was included. (Maybe that's why it was so cheap?) Not a lot bevause i rarely see them. Anyways, they leave us alone but still crawl on the tables, walls and in the cabinets in the kitchen. They don't bug me as much because I lived on a ranch near a pond where it was infested with the red and black ones that bite during the night. So as long as they stay away, I'm not too worried. And also the fact that we are moving next month because the landlady won't get rid of them. The couch and ottoman are being left because we know for a fact that's where they are. And everything that can be left, will be. So what my question is, even if we do happen to bring along 1 or 2 (or 3 or 4), think it would be effective to do this just as a kill them off at the beginning and hopefully prevent them from repopulating?
Ninzerbean (author)  katieh9323 days ago
Absolutely. Yes, bait the next house you move to right away.

Idk how it is everywhere but here if you're renting and there's a roach infestation the landlord has to get rid of it or you can get the lease terminated. So to those people who are renting and feel stuck because of the lease check the laws in your area you may be able to end it.

Hi,

I have recently purchased a place abroad. I work from home and plan to spend half my time there. During my last brief visit (I went to arrange for some building work to be done), I found quite a few dead cockroaches, and I have a total phobia. When coming back home and doing research from a safe distance, I realised that the black spots I had seen on floors, inside kitchen drawers etc. is roach poo and that the thing which looked a bit like a mouse dropping is an egg case. When I wipe up the black spots, new ones appear so I am pretty sure there must be quite heavy activity going on although I have not seen many live ones (1 half dead, and 2 babies in December). I feel quite optimistic after reading your "'ible" and have ordered 2 kinds of gel in addition to everything I need for your recipe. I go back in 2 days time and look forward to trying to sort everything out, although I am also dreading it.

My main worry is that I am having the whole place fully rewired, which means a few weeks of loads of new holes being made in the walls and so on. There will probably be a lot of dust. I'll try to keep it as clean as possible, but do you think the building work will interfere with the baiting? I'll follow the caulk/foam tips for pipes, around windows etc. where no work is being done. Once it is all done, I'll do the electricity sockets as suggested.

It is really good of you to be so responsive and helping so many people, good on you!

Ninzerbean (author)  karamba7126 days ago
Dear Karamba,
If I answer your question may I come visit? It sounds great in that it is sure to not have any roaches. Anyway the new wiring is a GREAT time to stick the bait in the holes in the walls. This is really super news. Roaches don't care about dust and dirt, they are looking for food. Just make sure your workers are neat freaks in that they don't stick food remains inside walls - a common practice - out of sight out of mind. Soda drinks are almost normal to find inside walls. But all in all this is the perfect time to bait. Get that stuff into every hole and opening that is made during the rewiring. Enjoy your roach-free second home!

If this works, and I am hopeful, you will be more than welcome ;-) I have some commercial gel baits which I will use in places as well.

I got here late last night, and I am pleased to say I have found no more dead roaches and no more faeces. I am happy, but also don't quite believe it. I am still going to blitz (although with a bit less urgency than I thought) and bait the flat, but I think and hope it was less bad than I thought and that it should all work out in the end.

Hello,

First I like to thank you for your information you provided. But there thing is I live in the UAE and I just moved into a new studio that have roaches every. Where. Mainly the kitchen, the toilet and pretty much anywhere. But here I don't think I'll find the exact same poison you're using to kill those unnecessary insects. Could you please tell me a substitute to use or maybe the anything with the same effect. I got the studio for a year and I know for a guy I shouldn't be afraid of those, but I have the biggest phobia. I almost got a heart attack once seeing a dead one upside down.
Ninzerbean (author)  George.A.Baskharon25 days ago
Is there a reason you can't order boric acid online in the UAE? There is no substitute that I know of that is as safe to use, but I guess any poison disguised in something delicious would have the same effect. But it would have to be really inert - have no smell or bad taste. Really, I just don't know.

Hi! Thank you for your well written instructable. i mixed flour, honey, boric acid powder as per your instructions two days ago. I baited my house as you suggested, especially around the kitchen area. I know it will take time to work but I have been seeing almost double/triple the amount of roaches in the past two nights after i placed the baits. I have been holding off on killing them on sight (one because they gross me out and two because I'm hoping they will eat the food and take it back to their lair.) I haven't seen them eat it (I put a few in cabinets in the corners so that I can check on the bait). Should I be worried that there the ratio isn't right? i mixed the flour/boric acid and added honey until it looked like peanut butter. I would greatly appreciate any advice! I've been poring over the comments but didn't find anyone saying that there was a big increase in roaches.

Ninzerbean (author)  aryali1 month ago

There have been comments about seeing more roaches after baiting, they do die down (puns are always intended) but it does mean that you have a nest somewhere inside that you must deal with first. Keep the vacuum out to use if you don't like killing the ones you are seeing. I know what you mean about grossing out. Normally seeing more is NOT the case but because it has been written about at least twice I think it is because you have not gotten rid of the infestation, so it will take longer. But that is only my guess. My infestation was beaten down by the professionals and then they used the bait to keep them away.

Your ratio is just fine btw. Just make sure you put it in ALL the places I suggest in step 7.

Thanks! I put them in all the places my dad and I could reach. They are german roaches and I saw that you suggested they might be harder to get rid of. I will let you know of any updates. Thanks for the reply. I checked behind the fridge, under the sink and in the cabinets but couldn't find the infestation. I'm not quite sure where else to look. If anyone has input please let me know. I

Ninzerbean (author)  onlygod1 month ago
Try getting some foggers and leave them on when you go out for the day. That should do the trick for the short term. I would not use my bait because it takes a long time to do it right and you are on vacation!

I just found this post and I definitely want to try it! The thing is, I'm pretty sure there is a colony inside at the least the electronic part of my oven (it runs on gas but has electric for the settings and such). Any advice on specifically where to bait for this? I can probably move the oven away from the wall but can't really take it apart and I'm nervous about putting any bait inside. Not sure how it would react with the gas. The house is a rental and the oven belongs to the landlord.
Ninzerbean (author)  alee131 month ago
You will need to get rid of the colony first. For many reasons this is the best solution. I would suggest a strong vacuum. Or better yet ask for a new oven from the landlord.
I doubt that they would provide a new oven for that reason... They'd say I brought the pests in. I can try a vacuum, I'm just not sure how to get to the inside of the electric panel

We moved into a house a few weeks ago and we are a bit out in the "sticks" and have noticed 1-2 roaches here and there but my husband was sure that they were waterbugs. I do not clean my drawers and insides of cabinets every week but I keep the surfaces and everything else as clean as I can. I am up at night very often and the other night i noticed a roach climbing up my drink. EW, i was able to kill it and look at it and determined it was a male german roach.( 2 black stripes and wings, ironic- because I grew up in germany) Today i started cleaning out all cabinets, behind the stove and the fridge. I found a roachfamily ( about 10) hiding in a cabinet we do not use at all, there is no moisture there either. I presented your Idea to my husband and hope we will try it out before getting an expert. I will definitely report back!

Ninzerbean (author)  SabrinaL21 month ago

There must be a link between your growing up in Germany and the... just kidding. Anyway have your husband read the comments, maybe a few hundred or so, ask him if he wants to see roaches at the end of each month or not at all. Exterminators do not stay in business if you don't have roaches. They have to make sure that the roaches only stay out of sight for 30 days so that you know that your money is doing something. So you will keep getting monthly pest control.

eltyshaun2 months ago
I hate roaches. The sight of them makes me go crazy. I recently broke up with my girlfriend and we are both neat freaks. So I had to get my own place asap. I found this place thst seemed nice. Was I in for a big surprise. I woke up in the middle of the night to get myself sonething to drink and they were everywhere. I also noticed there were different kinds big,small and tiny. I nearly lost my mind. Went to the store and bought all types of Tupperware to store dishes,utensils you name it. Whatever else that couldn't fit like my cups, store them in my refrigerator. I complained to the apt manager and he sent the exterminator out there twice. Yeah they killed a few but it seemed like more can to take each one they killed place. I even went to try to attack them on my own. I used thst roach combat blurt stuff that people were praising online, did nothing, still more came. I even put boric acid all over my house. Killed a couple but stil more came. I even watched a few evade walking into the boric acid powdered. Now I have intelligent roaches. Its getting so bad now I'm finding them getting into my bedroom which has never happened before. I'm afraid to wake up with a festation on my bed or even worst crawling on my face. I looked at some of these comments and sulfur acids is definitely a no no cause I'm afraid it might affect my tenants. Please someone give me advice that they know will work. I have 9 months on my lease and I'm high tailing it out of there if I cant get a grip on this situation. I wont even buy new furniture afraid they will get in it and start a colony. Guests, forget about it. Its an embarrassing and I dont want anyone thinking im a dirty person or they are scared to eat in my house. SOMEONE HELP ME PLEASE!!!!!!!!!!!!!!!!!!!
Ninzerbean (author)  eltyshaun2 months ago
Why are you asking for help before you have tried this? I understand how upset you are, I was that upset as well, that is why I wrote this 'ible. But you are going to have to use it before it works. It's like how hard it is to win the lottery if you don't buy a ticket. Be sure to read all 8 steps, read a few hundred of the comments, you will be fine very soon. Really.
I will try it, I also read a woman on here who is a stay at home mom tried it and she still was having the issue. I was beginning to think we both might be dealing with the same issue. I've spread boric acid roach enoz all over my apt snd it has failed. I'll try your method and can you tell me approximately how long it will take so I may contact you with the results?
Ninzerbean (author)  eltyshaun2 months ago

To determine how long it takes to see results you have to put your situation in the best possible light - look thoroughly inside for inside populations, look to see how to plug up any holes you have or spaces that roaches can come through, make sure you have almost no cardboard and your kitchen area is perfectly clean etc. The less you do all of these things the longer using my bait will take to work and viceversa. For the people I know personally, whose houses I have been in, it takes one day to see results. It can take about 4 hours to bait an average sized home. Using expandable foam and a vac and other prep can take a whole day. At the point I used it on both of my houses since I wrote the 'ible I saw results the next day. But the evidence of a severe problem at this, my second home, took a few weeks to be finally done with ever seeing a roach, alive. It was not until I redid the kitchen last year and was pulling the insulation out from between the studs that I saw that this house was a roach house for sure. It was very gross, but they were all dead. It had been over a year since I had baited.

Eltyshaun, this can be confusing information because I tend to write too much and everyone's situation is different, but depending on how big your problem is and how much prep work you do before baiting will determine how fast your roaches leave. Ideally it will be the next day.

Spreading boric acid powder around is the opposite of what I am trying to get you to do here, that will not keep roaches away, you won't do much good at keeping them away if you just kill some. You have to make your house a known death trap to the roaches, teach them not to come back. I urge you to re-read this comment, and the 'ible, and few hundred or so comments to get a grasp on what your problem is like compared to others and how hard you have to work. But once it's done it's done, your roaches won't come back for years and years.

Ok I'm going to purchase some foam sealant today and start the process. I'll keep you informed on the results. Wish me luck!!!!!

Ninzerbean (author)  eltyshaun1 month ago

Hey eltyshaun, give me an update, how's it going?

Hey Ninzerbean, first off I want to say thank you for your helpful information and for staying in contact. I did what you ask and for the first couple of days I saw a few take the bait and after consuming it, they would crawl away. Then a couple days later I would still see a couple around and a few always in my kitchen sink. I also saw some dead ones on the floor and in the corners. I started killing the ones I saw alive hoping I was helping the situation. Then a day later it got really cold outside and then I saw a couple. Now I see one or two every now and then and a couple days after that I've only seen one so far. Now for the past couple of days after that, I walk in the kitchen and I don't see any around like I use to, but I'm sure maybe one will come out or even 2 so I figure its still working its magic. I was right so now one or two would come out a couple to a few days later at a time especially the baby ones. So I'm still keeping an eye out because I have started the treatment on December 30 and it is now the 15th of January. I'm hoping by the end of this month, I wont see any more roaches. A new realty company has taken over my apartment complex and they have hired terminex and they want us to remove any baits or powders associated with killing roaches so that the stuff they use wont cause the roaches to go into hiding in the walls. I really don't want to do that because I feel that if I leave the bait that you recommended, in time it just might work and get rid of all the roaches. What's your thoughts on everything I just posted?
