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 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.

Yes, it says so in the 'ible, you just have to read the whole thing.

hi, let me start by saying I have a huge phobia of roaches, so as you can imagine, I have been having a very hard time since I noticed I had this unwelcomed visitors in my home. First it was only the big ones from outside, so i hired a professional exterminator, they came out once a month, the second month I notice a little one, the third time he came out I pointed it out to him and he said they were german roaches, after googling them I almost had a panic attack, seeing how fast the reproduce, and by then thinking i'd have thousands more, so he came out again and did something he called a "flushout" he used a little can to spray the cracks and cervices of cabinets and inside and many came running out, anyways, I thought that was the end of it. But no, now there's more than before, I see maybe one during the daytime, and a couple at night, mostly when i open the cabinets in the kitchen or in the bathroom, I don't walk into my kitchen at night at all, I'm literally afraid.

So yesterday, I made your magic potion exactly as stated, I found 100%boric acid, maple syrup, and flour, I had a limited amount of time, so I only placed it in the kitchen cabinets, drawers, under kitchen appliances, under sink, in the bathroom, and pantry, which is in the hallway, I saw one there, and behind the tv in the living room, i killed one there one time too, and above all doorframes, tomorrow, I will be going through the pantry, throwing away all boxes, storing everything in plastic containers, and baiting throughly again everywhere, but my question is, today, after halfway baiting yesterday, I saw a few very alive ones during the daytime, so does this bait, actually make them come out more before it starts killing them?

Ninzerbean (author)  belma.rueda16 hours ago
No, seeing more was just because you are opening up everything and so you just noticed more. I'm sure there are plenty of things in your house to feed them without this bait. I don't mean you are not keeping a clean house but roaches can live on toenail clippings for some crazy amount of time. You need to be diligent about vacuuming and vacuuming and getting rid of cardboard and worst of all you have to actually look for where they are living - this is really hard to do if you are like me and I think you are. You have to pull out the stove, look inside the vents on your microwave, shake your game players (gently) and read all of the comnets to learn more than you ever wanted to know. You need to finish baiting the whole house asap. If you don't think you can knock them down enough I would have fog the place, then again vacuum vacuum etc. It's a war, really. But a war you will win. Get some help though to deal with the fear factor. Keep me posted and good luck, it's a huge effort but it does pay off.

How long are you suppose to leave the bait/paste in the areas before cleaning and removing it?

Ninzerbean (author)  juan.mic.516 hours ago
There is no reason to ever clean or remove it, it's out of sight doing it's thing, no need to ever remove it.
Where can i buy the boric acid i was told to use borax i tried it kill a few but i didnt see any improvement i want to try ur receipt asap
Borax is not Boric Acid, it will not work. I just did a google search for Boric Acid and got tons of hits, Amazon, Wal-Mart, True Value, I don't think there are any shortages of where to find it. Good luck.

Dear Ms. Ninzerbean: Your roaches are by far the biggest I have ever seen. If your recipe killed those critters, I know it will send my puny roaches to their eternal rest. II hope your recipe will also eliminate some annoying crickets and just today - a mouse. Just one. Maybe. If your recipe rids my house of these pests, you should be given the Nobel Prize. Thanks for such a thorough, well written and illustrated Recipe to Rid Roaches.

Ninzerbean (author)  Allodyniayesterday
Dear Allodynia, It won't kill mice, and your puny roaches may be the German kind so read all the comments for help with these critters. Thank you for your nomination. If I could just rid the world of roaches I would be so happy. And chiggers too, they are the worst, but at least they don't come into houses.

We had tenants in our new house for a year before we moved in. My husband 'forgot' to tell me they had roaches. I have never been so disgusted by anything in my whole life. I am afraid to go into the garage at night. So far they are oriental ones and only outside and in the garage. Thank you so much for your recipe I am going to use it ASAP. I'm embarrassed to say anything to the neighbors since we are new, but I suspect the neighborhood may have a problem also. If this doesn't work I'm getting a new house or a new husband.

Ninzerbean (author)  suzysmith3 days ago
Yup, I hear ya. But at least your husband is not afraid of them - obviously - so make him dispatch them until you get the WHOLE place baited, and have him help with that as well, it's a big job. Good luck, it will work.
I found a boric acid roach killer at my local wal mart could this work just as good? Im anxious to try this and get rid of them things
Ninzerbean (author)  vanessa.mejia.73 days ago
You will have to read the back to see how much of it is boric acid. The stuff I used was 99% boric acid. Use your best judgement.
Katmom4 days ago

We have such a large problem, I'm not sure where to begin. Don't know how it started...

We see them in every room, especially the kitchen. First it was just kitchen really bad. We live in a 30 year old mobile home that had been updated completely about 10 years ago except the kitchen. We thought it was the cabinets being original and they were eating the cabinets. We remodeled the kitchen this spring with all wood cabinets etc. the problem has not gone away. Since then we have redone the floor and walls of dining room and both bathrooms in that part of house. We have a 2 story addition on the house, but they had never been in that part until recently when the problem seems to have exploded. We have had an exterminator visit 1-2 times a month for over 3 years. We are clean people who keep kitchen cleaned, all food in sealed containers, trash taken out, surfaces sprayed and cleaned with disinfectant type cleaners etc.

They crawl around everywhere in broad daylight. There can be 10-20 crawling around kitchen when it is clean. They crawl over stovetop while I am cooking, I have seem them inside the microwave even after it has been running, they crawl out of the dishwasher every time I open the door(even after it has ran), anytime I open a drawer or cabinet 5-10 will come running out. We even used the Kilz paint on every surface of the gutted walls before putting in new cabinets. We got a new oven, refrigerator, dishwasher, and sink as well. If we have been gone(even in day) or walk in the room at night there are literally hundreds on every surface. We gave up trying to kill them when we see them a long time ago.

They crawl all over the living room, dining room, bedroom, and bathroom walls and ceilings. Just this summer(after finishing kitchen) we remodeled the rest of the mobile home part. (This is the living room/dining room area, master bedroom, and the only 2 bathrooms in house) Because of the remodeling this summer we have painted every ceiling and wall in the mobile home part of the house and there is nothing hanging on the walls. (Note also that mobile home part is on a foundation with a crawl space and addition is on a concrete slab). I have seen them on my bed comforter, they crawl out of the bottom of the alarm clock when I pick it up to wipe off nightstand. They fall off the ceiling onto me in bed at night. I always turn on light and check toilet seat before using it. They crawl on the shower walls.(everything in bath is new - walls, ceilings, shower, tile, sub floor, flooring, vanity, mirror, etc.) we even have new sub floor and laminate flooring and walls in living room and dining room. Kitchen has ceramic tile that was put in about 10 years ago. Sitting on couch one can crawl across you, you will not sit anywhere for 10 minutes and not see one. I am not sleeping now because they have crawled on me at night. I am afraid that I will be in public and one will crawl out from under my sleeve or something.

I don't know what kind of roaches these are. I know I need to thoroughly clean kitchen cabinets and drawers. There is the black specks, dead ones etc. all over in them. But it is impossible to keep them clean with the scope of the problem. Even within a week of getting kitchen done they were dirty. I know they are in all the appliances, toaster, Keurig, microwave, etc. I even see them crawling across the digital clock display on the oven.

I want to try your idea. (Well, I really just want to burn the house down and everything in it. Or move, but the bugs would move with us. Or tent the whole house and fumigate it) I have read every page of steps and over 400 or more of the 600+ comments, but have some questions.

1. What steps should we take before we bait the house, due the scope of this?

2. Should we fumigate/fog/bug bomb the house, clean up the dead and their droppings, and then bait?

3. What is the difference in the above mentioned fogging/fumigating methods?

4. How do I get them out of small and large appliances, clocks, DVD players, game systems, etc?

5. What about our duct work for our central heat and air systems? Should we get them professionally cleaned?

6. What, if anything, should be done in the crawl space under the mobile home side?

Thank you for reading this and I hope you can respond.

Ninzerbean (author)  Katmom4 days ago
Dear Katmon, I don't have good news for you. I think the scope of your problem is too big for anyone but a professional. Then you are going to need a commercial type of shopvac to vacuum up before and after, many times. I have had no luck myself with trying to get them out of appliances. I had to throw out an A/C after hours and hours of meticulous work. You know that expression about sometime you eat the bear and sometimes it eats you, well in the case of appliances that you can't get into every single part, you lose.
I could go into all of your questions but I think you really need to call a small (not national) extermination company that will agree to come out every time you see a bug for one price, until you see no more bugs. Then bait.
My uncle, who refuses to do anything himself had this problem, he wouldn't use my bait, the problem got so bad they were fighting each other over food left on the counter, I refused to visit, then finally he found a small company that agreed to get rid of the roaches - and they did. But because he won't bait with my stuff, they will come back.
I think because you read so many of the comments you know what you have to do, fogging the place yourself will help alot, but your cleanup has to be thorough. The ductwork questions and crawl space questions are best answered by a professional. I wish I could be of more help but you will get this under control and then bait with my stuff. It is just one of those situations where every day it will get better, it can't really get worse right?

Will Borax work? Having a hard time finding Boric Acid..

Jordan I found Boric Acid At Co-Op today. It is on the Table with all the ingredients waiting for you to take action. Your pro-active I love it. -Your Dad. Ninzerbean Thank you for Answering Jordans question I've been buying Borax... lol, I guess we can get a lot of whites whiter... Single Father.

Ninzerbean (author)  JordanEaves_07 days ago
Hi Jordan's dad,
That is pretty funny. Borax is just washing soda so you may add it to the colors too, it's just like a detergent booster.

Well who would have known, thank you for the tip. I just can't wait to see the Results of this 'Ible. The people Next door have a Really Really bad infestation, they moved and new tenants came in last week, Geez, I've never seen so many of the things. Yes I'm a Guy but they Creep me out and scare me so bad my Daughter has to deal with this. I'm signed in as her I think, She's a bit sharper in some aspects...i.e. Computers. We really do appreciate the time you have taken to acknowledge us.

Ninzerbean (author)  JordanEaves_09 days ago

Sorry not to have gotten back to you sooner - no, Borax will not work. Someone found boric acid on Amazon. Have you tried online? Call some small hardware stores where you live. The big names don't seem to carry it because I think if they did they would not need to carry about 40 different cans of sprays and stuff that kill roaches but do nothing to keep them away.

Please I need help...my father purchased a house about 6 years ago which is where we now live...point is every now and then we saw a roach and we always got rid of them with Raid, but about 3 months ago the abandoned house next door got demolished and all the critters for some reason felt they were welcome at my house. I'm talking ants, spiders, roaches, rats ect. Despite all the pests my house got flooded with mostly rats and roaches...the rats we took care of the most reliable way we knew...we adopted cats. Although the cats succeeded in driving out the rat population there is close to nothing they can do about the roaches. Now that winter is approaching these unwelcome guests are just everywhere in my house including the bedrooms(before they limited themselves to the kitchen only!!)and last night one crawled into my ear ewww. I managed to get it out of there and now I'm just scared to go to sleep fearing this will repeat itself. People have mentioned to us over and over how they miraculously rid their homes of roaches and what they used to get the job done but unfortunately all those recipes are dangerous in a household with pets. My question is how can I apply this method in a home with cats and dogs...my biggest concern is our newest cat who is still young and likes to smell and lick everything he sees. Please someone reply with some useful information on how I may rid a household with pets of roaches!!!
Ninzerbean (author)  Carlos4495x37 days ago
See step #7. I think you are not reading the whole 'ible.
I am PETRIFIED of roaches. Just thinking about them makes my skin crawl. I live in an old house built in the late 50's so we have a lot of cracks in the foundation of the house. For the past couple of days I have been seeing more of those critters then I care to see. I am going to try this and hope I have the same success as others.
Where can I found the roach prufe powder
I don't know - try looking online, I have seen it as ACE hardware and it was at the small hardware store where I used to live. Maybe you can order it online...Some people have even found it at the dollar store.
I BEEN LOOKING FOR IT EVERYWHERE

Oh you know what? I meant to address the fact that you are looking for roach prufe powder and I forgot until now - anyway the point is to use Boric Acid. It just happened that the only boric acid I could find back in '09 was the 99% in Roach Prufe. But it's all about the boric acid (never to be confused with borax) and not the brand name. Hope that is more helpful than what I wrote yesterday.

YES IT IS THANK YOU SO SO MUCH
I mixed the exact ingredients exactly how you made it for your own house. As I'm putting out the bait a brave little roach approaches (no pun intended) the bait & turns away from it instantly. So I dropped more in front of him, he goes up to it for just a second and then moves on again. Is this normal?
Ninzerbean (author)  Andreacatanese089 days ago

Andreacatanese08, I was out of town with no internet and some questions did not get answered, so here we go: No, of course this is not normal - BUT the point of using this bait is that you are placing it in places that roaches run around, inside your walls, under the sink, behind drawers and all the other places I detail in step 8. So maybe your little guy was on his way somewhere and was not hungry, maybe he was trying to get away from you, who knows, but putting it out in the open is not how to use it or even why to use it. First of all if you have so many that you are seeing them in the daytime you have to use some other more immediate method to knock them down, get them under some kind of control before using the bait - I say this because there must be reasons that they are out and about - such as that they can find food everywhere, or there is a colony living inside of your game player, the microwave, the dishwasher, under the stove etc. You need to vacuum vacuum vacuum, get rid of all cardboard... you know what - I have to run, just read the comments, read ALL the 8 steps of the 'ible and keep in touch with how it goes. Good luck, sorry again for my late response.

Thanks for keeping in touch, keep at it so you get to 100%.

First off, thank you so much for taking the time to write this! With six young kids, I have been looking for a solution that works and from all the comments, this seems like the best option. I looked on Amazon and it states that the Roach Prufe has been discontinued by the manufacturer. The only other option is 99% boric acid and 1% lure. Do you think the "lure" will have an adverse effect? Thanks again!!
Ninzerbean (author)  maryellenlopez10 days ago
No, I think it will be fine. You are basically just adding more lure, and the other stuff makes it spreadable so it can be applied in places where kids and pets won't come across it. Keep us posted on your success

OMG thank you for this! I am going to the store right now to pick up these items. My apartments will do nothing but spray once in a while and when you keep your house pristine and they're still everywhere..I was dreaming of burning this place to the ground lol. Thank you!
