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

No more roaches!

I had a problem with roaches last year following a roof leak. It grossed me out. It was the big kind that are supposed to live outdoors. They found a way into my attic and it was terrifying to me since I am a big chicken about roaches, nothing else only roaches. I saw this recipe and didn't want to make anything that would be a bait and attract more but then I thought about how they would take it to their nests that I wouldn't even know how to find in order to spray or treat them. I did it and it has been Miraculous!!! Thank you!! No roaches, not one in an entire year! It took less then 2 weeks and even in the two week period I was seeing fewer and fewer. I didn't have a lot in my house but I would see a couple per week and I knew there was a lot in the attic. Had I not used this recipe I am sure I would have seen more and more and been disgusted every time. I saw a bug on my porch last night so I am making the recipe again today. He may have just been from the flower beds but I don't care, it is not starting again here. Thank you very much for taking the time to post this amazing information!!

Thank you so much for taking the time to write. I know it works, that's why I posted it so many years ago. I wish more people would simply do it. I mean just read the ible and follow the instructions.

I have had a serious German cockroach infestation for nearly 2 years. I just spent 2 weeks emptying my kitchen cabinets and moving all the appliances so I could dust boric acid and diatomaceous earth everywhere - everything is back in place and NOW I find your instructions! As soon as I catch my breath I'm going to whip up your formula and start all over. I can't believe I have to take all the switch plates off yet again. My roaches reside mainly in the kitchen. When I make a sandwich I have to be fast. If I have to go back to the fridge for a tomato or mustard there will be at least two roaches running at break-neck sped toward the sandwich! "Shy" is just not a word that applies to roaches. I am slowly making my way through the comment section here and I am amazed at the people who use wicker. German roaches love anything made of straw or wicker. I have had to discard everything made of straw and wicker because those materials provided so many hiding places that they were just teeming with Germans of all sizes - particularly babies and small nymphs. I will let you know how it goes. You have a very pretty kitchen - you must be a serious chef.

I don't know what the Germans use to kill "German" cockroaches but I do know that they call them "Russian" cockroaches!

For a problem as bad as yours I would also suggest that you get rid of any cardboard containers such as cereal boxes, pasta boxes etc., maybe even put evertything with a label into some giant zip lock bags. Also check your dishwasher if you have one. Or any appliances. I think you need to fog the kitchen. Let me know how it goes.

Thanks for your prompt reply! I have already put everything that was in a cardboard box in zip lock bags. From what I have read on other sites, fogging does not work well for Germans because they can hold their breath for 40 min. Is fumigating and fogging the same thing? I have two questions:

(1) How long does this formula stay spreadable? I am a slow worker.

(2) Does this formula definitely work for German roaches? I have now read all the comments and sometimes it is hard to tell if people are discussing palmetto bugs or German roaches. It appears that some people use this formula successfully with German roaches - but, then, there are a few who apparently are not successful even though they affirm that they are following your instructions to the letter. I have a few Palmetto bugs, too. So I am still going to do your formula. It is hard to live in SC and not have Palmettos.

Even though I have read that the only reason you see Germans during the day is because they are experiencing crowding - I don't know that I believe it. I have destroyed four nesting areas in my kitchen during the last month but the number of roaches I see during the day has not lessened. I think the reason I see them during the day is because they are hungry. Since I have been discarding food scraps left on dishes immediately and taking the garbage out every night before bed, daytime roach activity has definitely increased. My German roaches are very aggressive. When I cook, either day or night - as soon as they smell the food, here they come. They crawl right on the stove among the cooking pots. If I'm slicing and dicing, they come right up to the food prep area. They act as though it is their kitchen and I'm just the "worker bee!"

Ninzerbean (author)  LindaF17 hours ago

Dear LindaF1,

The bait will stay spreadable for at least 4 or 5 hours. But you can put it in the fridge and that will give you some more time. I now live in SC too. In the woods even. I still don't have roaches, except a dead one every few weeks, since I baited this house when I moved in 2.5 years ago. Fumigating and fogging are different. I really wanted to say bomb but am afraid Robot will hold up my reply to you. So anyway, I too of course have read all the comments and seen that some folks have had varying luck with the Germans, and I have learned a lot. This works like a charm with the palmetto bugs which was what I was dealing with in Ft Lauderdale. But in SC I have seen both and the Germans are the dead ones I find. No palmettos.

I recently talked to a restaurant owner about this solution and he was going to try mixing up a slurry of the bait and put it into standing water. This is fine for a restaurant but not something you want to do in your home - but in your case I think you might want to try something along these lines because unless you are pulling my leg you have a severe problem. Like your health is at risk from the bacteria and stuff these guys carry. You need to take really drastic measures.

Finding the infestations is fantastic, if not really gross, but I think you may need a severe knock down that only an exterminator can do, not a regular service call but something special. I would call a non- national company to find someone that can work with you and your situation until it is under control and then use my bait to keep it under control. In my situation there had only been infestation inside and it was in the bottom drawer of the oven in the house we had rented. But I'm worried that your problem is even bigger than " the worst infestation he had ever seen" as I wrote about in the beginning of my story in the 'ible.

I'm on vacation and using an ipad instead of my computer so there are sure to be tons of typos here. I hope you can work through them. Pls stay in touch.

LindaF1 aaryak19 hours ago

I admire your tenacity, aaryak. You must know something I don't! I have tried your method with no success whatsoever.

therese87 aaryak2 months ago

I read that if you do this you need to be careful not to leave any trace of the roach guts because that will attract more roaches as they enjoy feeding on the remains of their dead buddies :(

i will try this, but its hard to find the boric acid powder in japan, so i just bought the market ready roaches bait with boric acid. I bought something like rice cake flavor. I hope this will work. I upload an image of what i bought. The box has 16 pieces so i put it on every place that roaches may live. This post help me about boric acid

Ninzerbean (author)  Jonettemardavid23 days ago
I don't know, I sort of don't think this is going to be the same thing as my 'ible. I mean it does not seem to be any different than using the store bought stuff because it is just that. My baiting system is all about putting it (because it is sticky) on the backs of drawers, water pipes, behind toilets, up high, inside walls. I am sorry that you cannot find boric acid powder in Japan. Can you maybe try harder? A chemist shop maybe?
Companies do not want their roach bait to be effective in being brought back to the colony, they want you to see dead roaches laying around so you will think it is working, but that will not get rid of the problem. It will just make you buy more of it. If you use my system the roaches are gone for years and years, you only have to do it right the first time. It takes hours but it is worth it not to have to do it again for years.
I was out of my house for 2.5 months and got home last night and no roaches anywhere - dead or alive.

ok i already able to get the boric acid online and follow this step. i use mapple syrup. i hope they die very very soon. i have seen many of them at the back of the refrigerator, i have clean it and put some of this. ive been using a hoy hoy traps too.

Plus she can order online.

wireman3328 days ago

I first wanted to say thank you for sharing this information. My mother has started having a problem with roaches showing up, and its really started to get to her. She cant stand the thought of it. Im going to make your mixture and spread it where you have shown.

Secondly i want to comment on the social argument going on in the forum. And i'll have to agree with the NOT social side. The definition of a social insect is "any of numerous species of insects that live in colonies and manifest three characteristics : group integration, division of labor, and overlap of generations." Roaches do have two of the three, but miss out on the division of labor. There are no "queen, warrior, or working" roaches.

But yet they do form colonies, and interact as Nizerbean has stated. I read of one study where the group made a cockroach robot that had characteristics so close to the living creatures that it was able to get the whole colony to follow it to anouther living erea. I looked for the webpage that was on before commenting here. While i was unable to find that particular page, it looke like they might be marketing the creation already. But why go through all that when such a simple solution as this is available.

Thank you again Ninzerbean, best wishes.

Ninzerbean (author)  wireman3328 days ago

Thank you wireman, very interesting - thank you for taking the time to write. I think that the comments to 'ibles are as valuable or more so, than the original 'ible.

IS IT ANIMAL SAFE? I HAVE ALOT OF ANIMALS FROM BIG TO SMALL

If you follow the directions on where to put it your animals should not be able to get to it. I know that I would not my animals to eat it but on the other hand it should only hurt things that wear their skeletons on the outside. You should do the research you need to know. Don't just take my word for it.
boni149 days ago

Is it still effective after it get dry and hard?

Do you have to retreat. What about Apt. living? Thanks for info.

Ninzerbean (author)  boni149 days ago
Of course, depending on where you live and how humid and hot it is it will get hard or harder, but you want it to, you don't want it sliding off of all the stuff you have put it on the back of or on top of. If you don't use it all in one day it will be unusable to apply. I would only think you would need to re-treat every few years. I don't have first hand experience with apartments but from what I have learned on here in 6 years I think I would try very hard to get the other tenants on board.
shyatt25 months ago

I made this, after scouring the interwebs for different recipes what i have found is the same. It doesn't warn the roaches not to come back. The point is they eat it and they dry up and die. The roaches in the nests eat those roaches and die also. The syrup and flour/rice powder is the attractant. This is the same technique used in the little pods. Just much cheaper to make a large amount. Depending on your infestation it can take weeks to see results. This is why bombing/spraying to kill visible ones is important. Roaches come in waves as eggs hatch, so you will see them in crease in numbers before they dissipate. This bait will generally outlast the waves of roaches which is why it is much better than the pods. Once you properly bait your house with this stuff and they start dying off your house will be protected as long as it remains appealing to new roaches that come in from outside. Using an oil agent to keep it from getting rock hard can make it last longer. Source: I have successfully destroyed a german roach infestation with this recipe.

boni14 shyatt29 days ago

Thanks for suggesting the oil to prevent drying out and make it last longer.

Ninzerbean (author)  shyatt25 months ago
No, the bait doesn't warn the roaches not to go to your house. Roaches live in a colony like bees, they communicated to each other about where to go get the best food. The German ones live inside, I wrote this 'ible for the regular ones I had to deal with in Florida. When I wrote this back in '08 I think it was, there was no information online about baits, just digging and digging led to me discover that the pest control companies were stopping the use of this type of bait because people were canceling their contracts. Your information is very helpful, thank you for sharing.

best bait I 've heard of.. what also works is, if you see them in a path or a route, sprinkle baby powder down. when they walk through the powder they will suffacate because they breath through the underside. LOVE the borax recipe for places you can t sprinkle powder or for the buggers you don t see. I have wood roaches, because I live in an old house in the woods, and it works on them too! I have seen Florida roaches and they are really, really big and scarey so if it takes care of them, it will take care of every day roaches. thanx for the recipe.

Ninzerbean (author)  reikimaster55553 months ago

Thank you! And thank you for your tip about the baby powder.

shyatt2 shyatt25 months ago

Protip, german roaches use your electrical lines to get around the house. Make sure to bait inside your outlets, take off the coverings and bait inside.

Ivriniel5 years ago
Um, roaches aren't social insects so they don't form colonies.

Yes, they are very sociable.

Ninzerbean (author)  Ivriniel5 years ago
Yeah they are and yeah they do. Being that I saw a colony move one night I know this is true - a river of roaches - millions? Who knows. But check out LittleWolf's comments and some others, they attest to the social and colony stuff.

Ninzerbean,

Although it is clear they live in groups and have some means of communicating, still,I wasn't so sure about a "colony", so I did my own Googling and one thing I found, and thought you might find as entertaining is according to this list:

http://sciencebasedlife.wordpress.com/2011/09/26/w... (scroll down to "Invertebrates") where you will find that while "ants" live in a colony, a group of cockroaches is actually called "an intrusion"... This would imply that no matter where they might be, they are not welcome there!

At any rate, I thank you for your contribution, and for your continued support of this ible you were so kind to share. My story start with me moving in here almost 12 years ago... I happened to see 2 dead roaches the first day I got the keys, so I put off moving for a day and used several foggers to try and get rid of any infestation. I don't know if that helped any but I have had many small harmless spiders, I never had a single cockroach, not dead and not alive. NONE.

Well, until this last new neighbor moved in a few months ago. As soon as he did move in, I noticed a big jug of name brand bug spray sitting on his patio. That's a big clue, as far as I am concerned as to what was to come. Sure enough and it was a few weeks after he appeared on the scene that I saw the first cockroach... And downhill it went.

I must say I started with the easiest of ibles I found on here, the "salt" method... And aside from (presumably) salty feet it did nothing else. Then I went on to the sugar and baking soda... Or was it flour and baking soda? I think I did both. And while I have used Boric Acid (in a mix with sugar and water) to get rid of ants in my garage -And I must say it worked like a charm- I have never used it for cockroaches but am now down to your recipe...

While I cannot doubt how effective it is, theoretically, I don't think it will permanently get rid of the problem because while it might eradicate those that cross the border into my unit, they may continue to thrive where he is at. In all fairness, I should mention that while I do not buy or read the local newspaper in my town, it was shortly after I had spotted the first few roaches in my kitchen that I came across a news stand that showed the front page of the local paper with a huge headline that said "ROACH INFESTATION" discussing how this summer might present a huge challenge with the little critters. So while I maybe attributing the problem to my neighbor by way of the jug of pesticide he has, it might be this whole town that needs to be treated, better yet, eradicated.

And so I think I might be simply delaying the inevitable, that being moving out and letting them have the whole place. And if an when I do move, I will only be taking the bare minimum... No cardboard boxes, no "I'll save this that or the other in case I need it later".

Thanks again for your contribution and I will update you with my success (I hope) or lack thereof!

Ninzerbean (author)  Omarsibles23 days ago

Dear Omarsibles,

If you would be as good a neighbor as you are a writer then I am sure you could approach your neighbor, without blame of course (because it is possible he ended up with a used infested ps3 player as so many others have) and say hey we both MAY have a problem, let's see if we can fix it together. Or how about going to the person who wrote the article in the paper? I am not trying to make money or fame, I have no vested interest in boric acid or any other M.O. other than to rid the homes of the world of roaches.

But you are really a great writer, do you write professionally? Where will you move to? Do you really want to move? Don't let the bugs win! I just visited the greatest town on my way home from months of travel - Fredericksburg, VA. I think I am going to go back with my cape on and rid that town of roaches, and having too many letters in its name. Actually I have no idea if they have a roach problem there or not.

Keep in touch.

Ninzerbean (author)  Ivriniel5 years ago
I just did a Google search on roaches being social and there were many hits - too many to just list one, but really you can look there if you want proof. I put as the headline "roaches are social?" I hope this will convince you. It's one of the reasons they are easy to kill. If you had to kill one at time without their help in bringing poison back to the colony you would never make a dent.
Darkie231 month ago

Hi I follow your step that you has. So far I got it from store. Here what I have.

Hot Shot MaxAttrax Roach Killing Powder with Boric Acid

Normal flour.

Pancake syrup.

I did mixing them. Then my mom start complain because that way I made that for follow your step, it start to dry like rock. I told my mom I just follow the step. So I need to know if I did right thing. I just follow your step, that all.

cdavis381 month ago

After getting rid of them 10 years ago,I cried when I saw one the other day.I'm trying this,because I became so sensitive to chemicals the first time that I don't know if I could handle the exterminators again. I will post again after using it for a month to see how it does.Thank You.

Hello, I have a cocroach problem and every once in a while see one in broad daylight (maybe once every week) and at night when I get home and turn the lights on there are at least 2 or 3 of em in plain sight. I tried a mixture of borax and sugar (2 parts borax to 1 part sugar) which I placed in 5 different likely places around my house, but I'm not sure if it did anything. It has been about a week and I have found a few dead wasps and large dead ants, as well as a brand new trail of tiny live ants, but no dead roaches. I saw no roaches at all for a few days, and signs of trails in the powder I had laid out, but no dead ones around. Then I saw about 3 or 4 all in one room, and now, a few days later as I got outta bed to use the restroom I saw ::gag:: 3 huge ones. They did not look at all like they were suffering the ill effects of borax. They looked very healthy and happy. I am so squeamish I can't squish them, so I desperately used up a whole bottle of hand soap trying to pour it on them, but two got away, and I only was able to suffocate one of them. I think I need to try this recipe, but I have a few questions:

1. Can I use borax instead of boric acid?

2. Does this recipe work on the giant ones I have here in Louisiana?

2. Will I see dead roaches around if it is working properly?

3. Will this recipe continue attracting ants into my house?

Help! Thanks in advance!

Ninzerbean (author)  therese872 months ago

Hey therese87, I'm back, how are you doing with the roaches? Did you find some Boric acid?

I did find some Boric acid. I have not had the chance to make the mixture yet, but I am still seeing signs of having an infestation. My house has some pretty old electric wiring, and all the electric outlets are in the floor. Any idea how I would attach paste underneath them to where it won't just drop to the ground? Thank you! Actually, I have been finding a lot of dead spiders near to the borax mixtures I left out...no dead roaches though.

Ninzerbean (author)  therese871 month ago

Dear therese87,

I know I am going to sound like a grouch but again your questions only would be asked if you have not read the 'bile. Are you sure you are hitting the button that says "view all steps on one page"? You would NOT want to see dead roaches after using this bait. The whole point of it is for them to take it back to where they live so they can spread the news that your place is not a place to go to. They are like bees in how they communicate to each other.

Secondly it should not matter where your outlets are located for you to be able to take the covers off and (against all codes) put the bait inside the receptical.

Again, Borax is not, nor does it even contain, boric acid. If you have roaches and you have not used this mixture that I detail in this 'bile I am unsure of why you are writing about it not working. I am sorry if I seem at all negative, and believe me I have total sympathy with your problem, but the question about the location of your electrical outlets just makes me wonder what you are reading and what you are not reading. Can't u see from the photos that the whole reason for the paste is to be able to put it on vertical surfaces? Behind drawers, behind picture frames, on pipes, inside electrical boxes (again, against code) are not even vertical no matter where they are placed on your walls.

Ninzerbean (author)  therese872 months ago
I'm out of town and it's hard to try and answer from my phone but most of your questions are addressed in the 'ible and the comments. Borax will not work. I'll write more when I return.
FancyCheese2 months ago

I have a problem with large roaches coming into my home. They're not palmettos but the North American variety. I read that they don't live indoors but outside but an exterminator told me that they will sometimes live inside the walls. I don't even know where I'm going with this but I'm writing this in hopes that someone can give me some insight as to how to get rid of them once and for all. It's really taxing on me emotionally because I hate roaches (deathly afraid) and now.. whenever I think I see anything move from the corner of my eye I freak out. The main thing I'm afraid about is that if I do try this method out...could it possibly attract more roaches to find their way into my house?

Ninzerbean (author)  FancyCheese2 months ago
I really understand how freaked out you are. But this method is not going to attract more roaches to your house. Really. Trust me. I swear. Just read the whole thing through, read the comments, take you time baiting your home completely.

By North American variety I think you mean the big ones - those are indeed called palmetto bugs. The German ones are smaller and they do live inside of homes. They are harder to get rid of.
