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
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!

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!

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.

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)  eltyshaun22 days 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)  eltyshaun21 days 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)  eltyshaun14 days 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?

Ninzerbean (author)  eltyshaun8 days ago

Hi eltyshaun, thank you for keeping in touch. I will get to your question in a moment but first I have to ask how you can see roaches eating the bait - it should be in places that you can not see - behind drawers, inside the walls, around pipes under your sink, etc. Most roaches are doing their roach thing out of sight, the bait should be out of sight too. It really should not be possible for you to see them eat the bait.

But do not remove it when the Terminex (in my experience the worst of them all) people come, but make sure it is out of sight. Remember that the exterminators make money by getting rid of roaches for a month, then they come back. If the roaches did not come back the exterminators would go out of business. That is why they don't want you to use this bait. If you don't have roaches (and soon you won't) the exterminators will be out of a job.

The roaches ARE hiding in your walls - the stuff they use will cause the roaches to hid or die but only for a month. That is the dumbest thing I have ever heard. Does it make sense to you? You could be a jerk and ask for proof of what they are saying, but just make sure your bait is hidden - as it should be anyway - and let them do their thing, as long as you don't have to pay for it. I wouldn't let them in if it were me, but it probably won't hurt. I am just not into chemicals around my house.

Well to answer your question how I saw the roaches eating the bait, I put some bait above the windows frames and door frames and particularly on the window frame I saw 2 of them eating it. I told you, I had a pretty bad infestation since they were coming out during the day. Now since I last wrote you 4 days ago, I haven't seen any, even when I get up late night, early morning, I don't see one, not even a baby one. I can't thank you enough and I did think that was odd what the guy told me cause when I told the terminex guy I had bait everywhere he said good and didn't even spray any area. he most know something. Anyways, thanks again! I'm still gonna keep in eye out though just in case. If anything changes, Ill be right back on here hitting you up.

Ninzerbean (author)  llilitu7 days ago

Dear Llilitu, To find out what kind of roaches you have, you will have to research them, maybe online. That is way beyond the help I am willing to give because it would mean I would have to look at photos of roaches. Ugh. Could you delete your other two comments that are repeated below as they are just duplicates.

Well i was in my kichen, cleaning and making sure food in shelves were sealed. Made the bait like you said except my house is only 1000 sq. Ft. The next morning saw one eat some of bait and run to hiding place. Now they just walk past thr bait. Going to do rest of house today. Does it lose its sme or something the longer it sits? Because they sure arent going for it.
Ninzerbean (author)  Pixiewings88 days ago

Pixiewings8 - you should not have the bait where you can see it. See step 7 for where to place it. They are walking past the bait on their way to a dark damp warm place, those are the places you want to place a bit of bait, but really you need to follow the instructions in step 7.

Hi. Thanks for the reply. I did put it where you said in step 7. In outlets, on pipes, behind drawers, behind stuff on shelves, under stove, etc. That was just extra places where I put it

You are so brave! Thanks so much for posting this, I'm going to have to gather my courage and get it done. Hopefully it works well on German roaches.

Ninzerbean (author)  TerminalxSound14 days ago

Germans are harder because they live inside - you will have to search out their inside-nests to get a handle on them because they breed so quickly that you have to knock them down before you will see dramatic results from my bait. Read lots and lots of comments - there is a of experience to learn from there. Good luck, be brave. Look at game players, microwave ovens, get rid of all of your cardboard. All the info is in the comments and the 'ible itself.

We have to move out of our home asap. Between work and having a child it was hard to find a place in the city so quickly. We have never had a roach problem but I have seen a friend who did and it was horrific. I have severe anxiety and I couldn't deal living how they had to with my child. We have luckily found an apartment that is available. The apartment is nice, other then not have central ac and heat. However, they said the previous tenant had bad roaches. They assured me that the apartment was bombed 3 times and cleaned and the fridge was taken out. They keep assuring me it's nothing to worry about and told me they would bomb again if need be but shouldn't have to. I don't have a lot of options but is this a mistake moving in? Sure re roaches are gone now but since this is an apartment will they be back shortly after signing our life away?? Please help!!!!
Ninzerbean (author)  Inneedofadvice12314 days ago
I think it is good that the management was upfront with you about the previous tenant. But roaches like inside the walls, in warm and wet places like behind the pipes going into the walls. Bombing and removing the fridge is not a 100% sure thing to be sure there are no more roaches you would have to look carefully for any feces, or egg cases. You would have to pull the oven away from the wall and look carefully inside of it. Does this place have carpet? I would look under that before you move in. If you have no choice then at the very least use my bait everywhere before you move in. I am just a bit suspicious - why did they bomb the apartment 3 times? 3? Why wasn't once enough. Maybe pay an exterminator a small fee to thoroughly inspect the apt?

This is great advice. I flip houses for a living. Most of the houses I buy are initially in bad condition and are usually with a roach problem. From my experience, I would say I've been pretty successful getting rid of roaches. I would like to add a few more tips to supplement.

- Boric Acid Method. Works great! The important thing is to make sure you put it throughout the WHOLE HOUSE. This includes attics, AC, water heater, and all those other places where applying becomes a challenge. Instead of open areas, apply around edges, behind stuff, nooks, and crannies. Should be somewhat labor intensive. Gotta do this for at least 2 weeks.

- Winterize. This is probably the most interesting trick I picked up. Roaches need water to live. They can live for weeks without food, but die much sooner without water. What I do is cut off the water supply at the main. Then, winterize the home. Winterizing is basically pouring an "anti-freeze"-type solution in your pipes so they don't freeze. Its safer than it sounds. Basically, roaches don't drink this water. No water equals no roaches. This will require you to live away from your homes for a while. Then de-winterize. Turn on all the faucets and let the pipes clear out for about an hour. Get a plumber to do this. I pay my plumber $50 for winterize/de-winterize services.

- Boric Acid Part 2. I usually do this last. Spread some boric acid in powder form around the perimeter of your home. Roaches don't usually eat the powder form but they'll stay clear of it. If they trespass, they they will get some on their bodies. This will be absorbed, or they'll lick it off. Either way, they'll die from it.

Hope this helps.

Ninzerbean (author)  oldyes17 days ago
Great info about winterizing for those that can do this. It's nice to know that you are selling roach-free homes.

I go into detail in step 7 about where to apply the bait but most people skip that step. Since it can take 4 hours to do an average home by yourself how do you do it for 2 weeks? After you bait the whole house what are you doing for the other 13 days of the 2 weeks you refer to?

Thank you for commenting.

Some of them are very difficult to eradicate because they will form multiple colonies all over the house in every little place they can get into. They ESPECIALLY like warm places with small entry points. This means inside appliances and other electrical equipment like cable tv boxes, audio equipment, computers, power adapters, chargers etc. The female will stay inside there laying egg sacs and the tiny young ones will come out and spread the infestation.

Yes! I can't repeat this information enough.
You probably did but you weren't specific on how many days it took
How many days did it take to get rid of all the cockroaches
Ninzerbean (author)  hueritalopez19 days ago
Every situation is going to be different of course. For my situation I never saw a live one again after baiting. I am pretty sure I say that in the 'ible.

@ninzerbean - hello! We just moved into our first house, which is very old and saw NOTHING at all upon moving in - no signs of roaches whatsoever. Before we left for vacation, I noticed an "adult-sized" roach on the kitchen counter, killed it, and had a mini meltdown. Upon getting back from vacation, I noticed a small roach (like the size of half a hole punch) on the stove and then saw another the next day, also on the stove. I was having such a freak out that I pulled all appliances away from the wall - to see no signs of roaches behind them, just dust and some old toys, which I cleaned up. I also checked the cabinets and wiped them out again. We immediately baited following the steps you have provided. We did this about 3 or 4 days ago but we continue to see about 2-3 smallish (again like half the size of a hole punch) bugs. Does this method also work for these "babies" that seem to be coming from the oven? We've only seen two that were even close to being adult-sized (or so I think) - which I understand there could be MANY more, eeek. Along with everyone else, I am having major anxiety issues with this. Should I just continue to be patient and let the bait work its magic, or is there something else I should be doing? The only location we have ever seen any bugs at all is in the kitchen.

Ninzerbean (author)  nomobugs22 days ago
Firstly you must bait the WHOLE house, this will take a few hours. It doesn't matter that you are only seeing them in the kitchen, they are there for food but they live all over inside the walls. Be sure to view each photo, read all 8 steps. I think you have the regular ones and the little ones are babies that are hatching from egg cases. Yes, I understand you are freaking out. You have to get a grip and put this fear into perspective - there are far worse things so think of one of the more very worse things and dwell on that while you pull apart your stove.

I was happy to read that you pulled everything away from the wall to investigate but believe me they are somewhere. Think about what they like to be able to find them - warmth, wet, dark. Think about anything that you leave plugged in, if it is plugged in it gets warm. Roaches have no bones, they can flatten themselves into and under the tiniest places.

And yes, to your question, this bait will kill the babies you are seeing. Read the comment section, take a break and go investigate for any openings to the walls behind your dryer or washer, under the sinks where the pipes come in from outside, behind your dishwasher. Plumbers and builders do not care at all if the holes they make to install pipes are sealed. Really, they just don't care. Amazing eh?

Seeing an adult before you left on vacation worries me, if it was in the daytime especially. Anyway, stay in touch, let me know how it goes, especially if you find any anywhere unusual or if you didn't bait the whole house and it you find any holes that you can seal with expanding foam. That will make a HUGE difference. Just keep in touch, we can all learn from your experiences.

I don't think we will throw the eco-system out of balance if we rid the world of roaches.

Sevin Dust it dose MIRACLES!!! Solved my problems with in TWO DAYS!!! I had german roaches and many other roach species I had never seen before in my life RUNNING WILD!! In my new apartment I had major axiety. My god mom told me about Sevin Dust. Its a powder for out door use on gardens but my god mom has used it for years inside her home and it has never been an issue for her pets or kids and She did not mix it with anything she told me just pour the powder every were in corners and spread it out wearing gloves or a spoon but you can mix it if you want to be more discrete and dont want your guests seeing powder all over your place. I personally did not give a damn I perfer my guests to see powder then nasty roaches any day of the year! I poured the powder in the edges of each room in my apartment and spread it out with a spoon. I put it on counter top edges, inside cabinets, at the bottom of my windows and doors. I even went a step further and spread it on my patio and grass next to my apartment. The second day the roaches were gone!!! My god mom informed me it kills mice as well and its good to put the powder down every 4-8 months. I have researched the Boric Acid and its very popular as well but I did not find out about it till after using the Sevin Dust wich is now my new Best friend!!
Ninzerbean (author)  Jiad24 days ago
Jasmne.Dai, Here is a link to the Material Safety Data Sheet on the poison you have put inside of your house - dangerous to you, pets, children, bees, plants, the water system, you name it and you have harmed it. I would suggest a respirator and lots of vacuuming to get rid of it. Or call in professionals, you are at risk. It is not a product to use inside, it is not a product to even touch with your hands, it is DANGEROUS and you should warn anyone who comes into your house until you can get rid of it. I'm sorry to tell you this but after you read the MSDS I think you will be as concerned for your health as I am.
Jiad Ninzerbean24 days ago
Thank you I do appreciate but again my GM and I have recently meet others that have used this for years as I stated before inside the home and has never had an issue and they are very healthy people and the animals and kids have never had a issue and mind you my GM Is now in her early 50's her 3 kids now in there twenties. She started the use 10 years ago. I meet her friend that actually got her hip to this and she has a hudge house and a big family along with pets and has never had a issue. She infomed me once she got it on her skin nothing happened. She simply washed it off. I think that warnings label over do it some time for the companies saftey they dont want to be sued lol but I feel if it were that bad the people who I know that have used it would have all been sick or some sort of issue by now. So to each its own if you dont feel its safe in your opinion its simple dont do it.
Ninzerbean (author)  Jiad23 days ago


I appreciate that you don't think there is any harm in the insecticide that is for outdoor use that you are using inside because no one you know has gotten sick. I appreciate that you are, like myself, trying to help people - but this is not the place to advocate a known poison such as Sevin dust when what I am trying to do here is give a nontoxic way to rid people of their roaches, a way that won't harm our eco-system, bees, dogs, cats, pets, children, a bait that can be applied as a paste so that it can be applied in places that animals and kids can't get to by mistake and even if they did it is not toxic. Your method posted here in the comment section, is only going to confuse people into thinking that I advocate Sevin dust. I don't - and this is why: from the MSDS: "Repeated overexposure may cause more severe cholinesterase inhibition with more pronounced symptoms. May lead to rapid onset of nausea, vomiting, diarrhea, abdominal pain, involuntary shaking, excess salivation, pinpoint pupils, blurred vision, profuse sweating, temporary paralysis, respiratory depression, and convulsions. Do not take internally. Inhalation Harmful if inhaled. May produce symptoms similar to those from ingestion. Avoid breathing dust. Chronic or Delayed Long-Term, This product or its components may have target organ effects. This product or its components may have long term (chronic) health effects."

Call me overly cautious, but why take a chance with a chemical such as Sevin powder, that if you get on your skin you need to wash for 15 minutes and call a poison control center? The common sense that you are advocating tells me to read the directions. MSDS's have saved the lives and quality of life for many people who otherwise would still be using toxic solvents in an unsafe way in schools and workplaces without otherwise knowing the long term effects of doing so.

For the long term health of everyone who comes into your house, eats food that your prepare or wonders why there are no bees outside, I can only urge you to get that poison out of your house.

Jiad Ninzerbean24 days ago
I showed my GM and some friends your method and they liked it as well and found it to be A great ideai!!! Its just they are used to the Sevin Dust method.
Jiad Ninzerbean24 days ago
And also I forgot to add that MSDS sheet is no different than poisons I have read up on in the past that can be placed in the home to rid bugs, mice etc... Its common sense you dont go around putting things like this inside your mouth or sniffing it up your nose. Thats asking for trouble. Now another product I used in the past that is really good BUT caused my eyes to burn and turn red was Raid spray and When I use bleach it dose the same thing. I actually had to open windows. Its alot of things that can harm you. That every day people use on the regular and again its just common sense. Im not going to be sniffing in Raid or bleach up my nose eithor.
Hello. Thank you so much for posting this and checking up on it. I used this recipe about a week ago. I have it all over my house. Ever since I did it, it has been so much worse though. I see them everywhere. Before it was just in my kitchen. Now I am seeing them all over my house. It is literally causing me so much anxiety. I am pregnant with two toddlers which doesn't help. I have read the whole post multiple times, so I'm pretty sure I did it right. Is it normal for them to all come out after doing it? Is there anything else I can do? We will be buying a house next year and more then anything I don't want to bring them over. We will be leaving all the kitchen appliances. Thank you so much for your time.
