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

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.

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.

Ninzerbean (author)  onlygod11 hours 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)  alee13yesterday
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
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!
Ninzerbean (author)  thumplover885 days ago
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)  thumplover884 days 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.

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)  SabrinaL212 days 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.

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)  eltyshaun29 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)  eltyshaun28 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)  eltyshaun21 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)  eltyshaun15 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.

Oh eltyshaun this is great news, I feel like we have been through a lot together and I am so glad your hard work has paid off. Thank you for writing!

How can u tell what kind of roaches they are we moved into an apt complex that is infected
infested they moved us apts but the same problem everyone we hv talked to said they hv the same.problem b4 moveing our stuff in this apt we bombed 3times and nothing has resolved this issue
Ninzerbean (author)  llilitu14 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)  Pixiewings815 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)  TerminalxSound21 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)  Inneedofadvice12321 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)  oldyes24 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.
DanDeLion4025 days ago

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.

Ninzerbean (author)  DanDeLion4025 days ago
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)  hueritalopez27 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.
