Introduction: No More Roaches

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.

Update: By the time I moved from this home described here, the roaches stayed gone for 6 years, I baited one more time inbetween. It is important to click the button right under the title that says '8 Steps' or you will think that this 'ible is only one step long - it is 8 steps long. Be sure to read all of the steps before asking questions. Other questions you might have, might be answered in the comment section. Which is not to say not to ask questions, please by all means do so if you need to.

Step 1: What You Will Need

Picture of What You Will Need

Boric acid powder*
Karo syrup - you may substitute honey, maple syrup, pancake syrup or make a simple syrup of sugar and water.
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 flour - any kind of flour is fine: white, whole wheat, rice, etc.
Enough Karo syrup, or what ever sweetener you choose, to make a peanut butter-ish 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 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 (any flour will do) 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. If you don't get finished baiting in one day put the bowl into the fridge, covered, and it will stay workable for another day or two.

*(Sometimes 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). Also, commenter ScottP6 says he was able to buy boric acid on Amazon for $7 for a pound. That is enough to share with neighbors and friends for years. Any boric acid that you find will be fine though, just make sure it is mostly boric acid.

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

Picture of What My Kitchen Looks Like Now

No more roaches!

Step 4: Once Upon a Time....

Picture of Once Upon a Time....

About 16 years ago I rented a house that was infested with roaches, I called an exterminator who declared it was the worst infestation he had ever seen (in case you don't want to take my word). His company used a bait that had the consistency of peanut butter and he put a little dab of it behind all the drawers (out of reach of pets or children), under the sinks on the pipes coming out from the wall, and he even took off all the outlet and switch plate covers to put the bait inside the walls.

It was a miracle, I never saw a roach again. In that house.

When I moved I used the same service and the same guy (let's call him John because that was his name) did the same thing, but this time is was a new house that I had bought. Once a year John would come back and do the same thing and in 14 years I never saw a you know what. Alive that is. Once in a while there would be a dead one. Back then I had a husband so the dead ones were not so much a problem.

Step 5: Then.....

Picture of Then.....

The husband left, I had to move and buy a new house and guess what? I took John with me, but this time John wasn't using the bait. In fact I was calling John every week for help with the roaches. My new house was new to me but really very old, and it had a lot of roaches. A week would not go by when I did not see one or two or .... more. It was so bad I could not get out of bed at night and turn on a light for fear of what I would see. I implored John to use his magic peanut butter but he just told me "we don't do that anymore". What was a poor girl to do?

The Internet to the rescue!

Step 6: And This Is What I Found Out!

Picture of And This Is What I Found Out!

The magic peanut butter that John's company had been using was so successful that clients started canceling their contracts. Oh. Gosh why hadn't I thought of that - who's going to hire a pest control company if they don't have pests. John wasn't using the stuff that WORKED because if he did his company wouldn't have any business.

It has been 10 months since I ended my contract with the pest control company and I baited my house with my home made poison, and (drum roll please) I have found one dead roach in all that time.

Step 7: How and Where to Use It

Picture of How and Where to Use It

Using the popsicle stick, put a dab of the bait where roaches like to go - up high and near water. They also like to live in your home's walls so undo all of your switch plate covers and outlet covers and smear some on the back of the outlet cover itself. The bait is not sticky so I find it easier to put it in areas where it can sit so it won't fall off. After it dries out it becomes hard and stuck to where you stuck it.

Roaches like to bring food back to their colony and when they bring this food back it will kill lots and lots of roaches, roaches who never even scurried over to your house. This is disgusting but even if he's a greedy roach and just eats and does not share with his buds, when he poops back at the colony and his buds eat that poop they will die.

It took me most of a day to go all around my home looking for out-of-the-way places to place the bait, undoing all the switch plate covers took the longest. Pulling out the drawers in the kitchen was really easy because most of the time you can access the back of the drawer from the cabinet underneath. At my former house it used to take a crew of 2 guys, 4 hours to do the whole house.

The most important places are the pipes coming into your home either for your sinks or you washing machine and dishwasher. Attics and crawl spaces are prime roach habitat. Roaches have no bones so they can slip through the smallest sliver of space. It's gross.

Step 8: Why This Works

Picture of Why This Works

Boric acid powder is a proven roach killer, what I am presenting here is a way to get the roaches attracted to it (sweet smelling Karo syrup) and to eat it (flour and Karo syrup). Making it into a paste enables you to place it in areas where powder alone would not stay.

I read a lot of information online 10 months ago to come up with this solution but aside from the boric acid powder it's not an exact science - I think peanut butter mixed with boric acid powder would work just as well. The thing that really got me really interested is when I read industry information about folks canceling their pest control service because the baiting method was so effective. I made up the recipe based on common sense, what I read, and what I had in the cupboard. The proof is my roach free house. It's a huge relief and I wanted to share.

2015 Update: It's been 6 years since I wrote this and I would like to add an especially helpful comment by NorEaster. There are over 900 comments at this point and they are very helpful, so here is this one, know that NorEaster's comment is about German roaches, which are a whole different bug game:

NorEaster to jules0803
Hope I can help with this. I moved to Hawaii 2 months ago and have already seen more roaches here than I've even seen in all my life (zero). I spend all my days planning and preparing for my escape off this infested island when military orders are up in 3yrs. So far this is my list:

(1) Get many, I mean A FRKN TON of airtight plastic storage bins (ZipLoc weathertight is a brand), it may end up costing, but its the way to go since roaches love to hide & lay eggs in the flaps & weaving of cardboard boxes.

(2) Tiny roaches will live & breed in the motors of appliances so toss them in plastic/garbage bags & store in freezer for a couple days before the move to freeze the life out of them!

(3) wash all your clothes, curtains & bed linens on the hottest setting (without damaging) and IMMEDIATELY move them from dryer into plastic bins so roaches wont have time to attach & hitch a ride.

(4) Those efficient little devils can feed off of the GLUE in your book bindings so throw all your office supplies, magazines, tampons, diapers, etc into the sealed bins with a roach bait station in every bin to feed & kill them & DONT open the bins for a few weeks, so that any placed eggs can hatch, feed & die also.

(5) Do a thorough cleaning of the new place before your stuff arrives, behind fridge & oven, etc then bring your stuff over & shake everything off outside! I know you'll worry what the neighbors think but at least they will see that you obviously are not comfortable living in filth & are taking measures to avoid another such situation. Wipe down & inspect everything before stocking shelves & cabinets & rewash all the linens again for good measure. I wish you luck & cant wait to do this myself in the roach-deterring snowy weather of NewEngland!

Hi I have been following this thread for awhile now and reading all of the comments. I moved into my apartment about a year ago. I never saw a roach until last October... my boyfriends sisters apartment is infested with them and we watched her puppy for a few days and she left the dog food in my pantry while I was at work. I immediately dumped Food grade DE as soon as I got home from work thinking I would be safe. But sure enough, about a week later I found a German cockroach on my bathroom floor. It looked like it was in the process of molting because it was a whitish color and not very big, however grossed me out! That day I went and bought the boric acid. I did not have a lot of money at the time so I used what I had in my pantry. I mixed it with flour, peanut butter and simple syrup. I placed it everywhere. Switch plates, behind pictures, door frames, pipes under bathroom/ kitchen sinks. I also did a deep cleaning in all cabinets and behind my stove and fridge and bleached my entire house pretty much. I was not able to buy the spray foam as I did not have a lot of money. My dad gave me some caulking and I tried my best to seal what I could, however it was super hard to squeez out. There is still a huge hole under my sink. So I let it go and two months later I found a small one on my window sill behind my bed that was flipped on it’s back and appeared to be dying. I feel as though the bait has worked but maybe because I did not spray foam is why I saw one? I am going out to buy the spray foam this weekend and I am going to touch up the bait as well. I’m so stressed out and literally losing sleep because of it. If anyone has any other tips on getting rid of German cockroaches let me know. I want to live in peace without one popping up in my face every few months. I was also given a can of gentrol IGR(insect growth regulator) it basically is like birth control for insects. It comes in an aerosol can. Does anyone know if this is okay to use along with the bait? Thank you for making this post. It really gives me hope that I can win the war on these things.

Ninzerbean (author)SJMxo2018-01-17

I think finding an occasional dead roach is to be expected and while not exactly welcome it is better than finding the alternative. You did the right thing with the DE and might it not be a good idea to turn your boyfriend's sister on to this 'ible? I also want to address the spray foam - yes it's a good idea especially under the sink as roaches love love love water, but even when you do this I believe you will still find the errant roach that makes his or her way in and then will die before he or she gets back to the 'colony' to tell his buddies that your place is now off limits. It's just going to happen and you shouldn't blame yourself or the method. It takes time and the fear lives on a lot longer than it should but one day this will all be a distant memory.

SJMxo (author)SJMxo2018-01-16

Obviously I would not spray it into the outlets.

RainbowS5 (author)2018-01-15

I'm embarrassingly terrified of cockroaches and we've been having an infestation of huge australian roaches the past few months, so I'm going to try this out after a top-to-bottom clean of the house! After some googling, I've found that other people have recommended putting onions and bacon grease into the mixture to make it even more tempting to the little buggers. I'm going to try putting a chopped onion in the blender to really pulp it up, before mixing it into the paste.

Ninzerbean (author)RainbowS52018-01-16

Why mess with success? It takes hours to bait your whole house, why would you potentially waste your time with something like raw smelly onions?

DonS150 (author)2017-12-21

I used this and it seems to be working. I used a raid fogger last week and still saw the german roaches. I found this and decided to try it. Since the application i am seeinng less and les roaches. Only saw one small roach this morning. Great instructions here. Thanks for the article!

Ninzerbean (author)DonS1502017-12-22

Thanks for the feedback. Be sure to follow all of the instructions and you will have success within days.

DougR56 (author)2017-11-20

Made this just now. Dollar general sells 100% Boric Acid 1lb for $2.85. Basically 2:1 BA to flour, added corn syrup and kept stirring until it was really thick. If it was two thin, added small amounts of boric acid until it was stiff. I stirred this mess with a knife, also doubles as an applicator in all the right places.

I'm going to all out war against this things, they destroyed 2 tvs and a playstation, and are in all of the outlets/switchboxes. It's a mess. I will post results soon.

Ninzerbean (author)DougR562017-12-01

A cable box? - I wish you were kidding.

DougR56 (author)Ninzerbean2017-12-03

Nope. Went upstairs today... found cockroaches all over this other cable box. Raid to the immediate rescue before they totally killed it. Sprayed behind 50" tv too. They killed one of those last month in another bedroom. It's disgusting. It's a fight to the death here.

Ninzerbean (author)DougR562017-11-21

OMG! 2 TV's and a playstation? Unreal.

DougR56 (author)Ninzerbean2017-11-30

Plus a cable box. What a nasty freaking mess!

MeganB133 (author)2017-11-30

Thanks so much for this! I just moved to a new house and guess what? Cockroaches! Even the word disgusts me! I have a bottle of green cleaner on my counter for when I see one and can find the nerve to face it. It knocks them dead with one spray, oddly...Still not sure why. Anyway, we have the powder and sticky traps -
which I hate! - but alone its not doing much. This is the solution I have been looking for. Thanks so much! ☺

Ninzerbean (author)MeganB1332017-12-01

Aw it's so awful I know, but this will work, you will be roach free. It also helps a lot to read some of the comments - there are thousands, just to hear that you are not alone, and some of them are so funny you will be laughing.

AnnaH131 (author)2017-11-19

Hi! I finally decided to make this. I have German and cockroaches. So I put it everywhere I just haven’t got a chance to foam yet. The big cockroaches are dead I haven’t seen a live one of course. Now as far as the German ones goes, I’ve noticed the babies will eat it and die but the medium sized ones that have the babies will not eat this stuff once they realize that it’s poison. Thank you so much for posting!! My roach problem has become a small issue instead of a big issue. Making this bait was a great start. I will continue to rid my house of roaches.

Ninzerbean (author)AnnaH1312017-11-20

Holy cow - you are so brave to be watching the roaches eat. If your roaches are that smart - that they aren't eating the bait when they realize it's poison then maybe try a different additive such as jello powder? or anything else that you see them eat. Keep in touch - your empirical evidence is very interesting.

Begone07 (author)2017-03-06

Hi!! I found your site in complete desperation. After reading several hundred comments I was convinced I'd try. So after 2 days of a complete cleaning spree and baiting every outlet and foaming every crevice I could find, im feeling hopeful. My question is
Is it normal to see them more after baiting? I believe I found the nest. Which was Christmas boxes stored in my living room cubby. I just threw the whole thing away. Oh, I live in Florida. So I'm plagued with German ???. Thank you so much!

AnnaH131 (author)Begone072017-11-17

Has it helped since you baited? I have German and cockroaches

bross128 (author)2017-09-24

When I made my peanut butter, I had to add more than 3/4 cup Karo syrup.I'm a little worried that mine was not quite the consistency of peanut butter. It says as it dries it will harden so I think it should still be fine. Even when it hardens, the roaches can still feed on it?

nccountrygirl (author)2016-06-08

hi, I made the magic peanut butter last night and put it out all over my house like you said. This morning I got up and I have live roaches every where and they come right up to you lol what did I do wrong ? Please help !!!!!!

Ninzerbean (author)nccountrygirl2016-06-08

I'm at a loss. This is a new outcome. Wait a day and write me back.

sprowley (author)Ninzerbean2017-08-29

When you poison roaches with boric acid they die slowly. They begin to roam around randomly without purpose as they have been poisoned and no longer act normal, as in hiding during the day. If you see them the next day, during daylight hours when you don't normally see them during the day, it actually means that they have eaten the bait and are in the process of slow death. They are actually losing their minds from the poison and come out at random. This can be confusing as you see more roaches, but it's actually a good sign that your bait is working. You should see less and less as the poison goes to work and keeps working for you over time.

Zaloma (author)nccountrygirl2016-11-13

That's what happened to me

Duncanstevens (author)2016-11-19

I made this yesterday after my housekeeper had been to clean the house. I put it everywhere and wheh i got home there were even more cockraoches running around my kitchen than normal. I have no idea why that would be and what went wrong? I got up this am and opened the one kitchenboard where i normally see a few (and where i baited) and there they were walking around. Please help

Ninzerbean (author)Duncanstevens2016-11-20

This has happened before- I mean twice people have written of such a thing, apparently you have Germans, which live inside the home vs outside, I understand your frustration, others have written of this happening - but I think they are looking for food as they have found the bait dangerous. I hope you will see less every day and then none in just a few days, if not I hope you will write again. Have you put the bait everywhere - the whole house has to be baited, not just where you see the roaches. When I wrote the 'ilbe 8 years ago there were no German roaches where I lived, I had never heard of them. But according to the faithful who write in the comments this will work for Germans as well, pls keep in touch, and read a few hundred comments for help - example - maybe there is a nest in the kitchen you need to find and dispatch.

KirthiR1 (author)2017-07-09

What's the foam? Is it the same as the butter recipe?

AngelaP103 (author)2017-01-22

Does this work for any kind of roaches? I have the small german ones, i think they are called. Is it a pointless endeavor for me to follow these steps? Is there something else I should do? Please help, anyone who has used this stuff for german roaches and let me know if you have had any success. Thanks.

DakotaLally (author)AngelaP1032017-05-18


To answer your questions:

There are more than 3,500 species of cockroach, I'm not an expert, but I would say probable not on every type of roach. Boric acid DOES work to kill German cockroaches.
Is it a pointless endeavor? No. It is highly effective.
Is there something else you should do? If you aren't happy with a professional exterminator's results or cant afford it, there really isn't much other choice.
"Please help, anyone who has used this stuff...", there are hundreds of comments here, including my own, about how they used these techniques to get rid of their infestations successfully.

If you want any specific advice, it is this, read the article again. I'm about to read it again to refresh my memory on the various tactics, I recently employed only one of the suggestions and plan to review the article for other ideas.

DakotaLally made it! (author)2017-05-18

You will not believe the non-sense a pest-control guy just told me!

We just got out quarterly pest control service at our apartment complex. The building has a pretty serious German cockroach problem, I have been trying to defend my unit for over a year now. I didn't keep good records, but over time the population has grown and dwindled, or moved on and returned, however you want to put it.

After they repaired a cracked drain pipe in the kitchen(gaping crack 3-4ft long in large iron drain), they virtually dissapeared. I had also treated most baseboards in the unit with boric acid. They were gone so long I let down my guard a bit, and over time, swept up all the remaining acid (it was like 6 month old by now). Sightings fell so low I actually was able to keep a log of size, location, time of day, if there was any potential lure (3/22-4/28, I saw five roaches, two were tiny babies).

About two weeks ago, after extreme rain hit the area(but I don't think that was the cause), they came back with a vengeance! Full size adults, pregnant females, sightings of 2-3 roaches per day! I have since thoroughly cleaned my entire apartment and treated all baseboards with boric acid(except bathroom, I mop daily with pine-sol).

When they came for routine pest control, I pointed out the boric acid and asked if it would interfere with his spray, if so, I would sweep it up. This dude told me that it wouldn't affect his spray, but that it wasn't very effective either, and that his supervisors have told him that it is bad for your lungs to treat with it. I know you dont want to breathe it, but I asked to confirm it wouldn't just waft in the air by sitting near the baseboards. He told me "I cant really smell it here, so it shouldn't be a problem". WTF? I have accidentally inhaled small amounts during treatment, it has no damn smell at all, of all the products out there, i'm certain boric acid is one of the "safer" options. He also claimed that as soon as they walk through his spray they will die. BS! I am confident that all of his rhetoric was nothing but lies that spread in the industry to protect their own self-interest and income.

Im not saying pest control service is a scam at all, but for roaches, the boric acid community has another follower.

Tljo (author)2016-11-22

Was hoping that maybe you still read these comments and reply! I have a roach problem, help!

Never in our lives have we had roaches. We are pretty clean people and have never had a bug problem before in general.. and then we moved to an apartment in a 4 bedroom flat in downtown Soulard (st Louis). This is a historic district so you are very VERY limited on what renovations you can do.. we are renting however. The building itself is very old. If I had to guess I'd think the are coming from the building next's pretty close and the back looks uninhabitable.. However the interior of our placeisn't terrible, just a little outdated.

Anyways, the week before we moved my boyfriend went in and painted the whole place. He said he saw one roach but that's all and wasn't concerned. However it seemed that someone (landlord or previous tenant who also seems pretty clean, I viewed the apartment while she still lived there) left behind roach hotel trap things. She had moved out earlier so it had sat empty for a couple weeks. My boyfriend mentioned to our landlord he had seen a roach but our landlord insisted that they "were just water bugs" and he "sprayed" (what he sprayed, I don't know).

Fast forward a couple days and we are cooking our first meal in the new place.. right as it's done, I mean literally as we are getting plates down, 5 or 6 pop up over the back of the stove - a medium sized one and the rest were pretty small. Upon researching they look Ike Germans. We sprayed bug spray all around the area and chose to get take out instead.. but now we keep seeing them.. on the stove, on the counter, on and in the dishwasher (keep in mind these are all on the left side of the kitchen which is also the wall that faces that empty looking neighbor building)... now they are progressing to the other side of the kitchen which has the pantry.: if I flip on a light at night a couple will scurry under the pantry doors.. I purchased tempo spray for the baseboard and doors and advion gel bait but does anyone else have any tips?? I'm absolutely terrified of them! We've been keeping everything spotless, and luckily it seems they are only in the kitchen so far, however I've quit eating the food from home cause I'm too grossed out.

Oh and none of our neighbors said they have had any problems. What do I do?? We have a BRAND NEW $1200 washer and dryer in that kitchen that I'm 100% scared they are going to infest!

George BS1 (author)Tljo2017-01-22

Hi Tijo, We had them in our electric range and the dishwasher. What happens in the dishwasher is they come up the drains, then they go to the electronic panel of the dishwasher, behind the push buttons. They love the warm electrical circutry. The german ones are tenacious. YOu have to put bait in dishwasher, they love the dampness inside. One thing I recomend is after you use dishwasher, keep door open to let dry inside with ac on or heat. They can live months without food, bud only a week without water. They love kitchens because of food crumbles, ware electronic wires and mosture of sink and dishwasher. Good luck it is war against them.

Ninzerbean (author)Tljo2016-11-22

After you follow all of the steps and still have roaches lets talk - I don't think that will be the case of course, but you need to do that first. I do not know about the stuff you already used - I only know my method. Germans are harder to kill, it will take finding out where they are living in your house and getting rid of that nest - the vacuum will become your best friend, and then baiting.

Tcoates21 (author)2016-12-22

I tried your bait last night and today i woke and found a dead roach! Im so pleased that it begin to work within one night! Thank you so much!

juliaq (author)2016-12-21

This instructable saved me! We recently bought a home that unfortunately came with a ton of roaches. We spent the entire first weekend following the steps - bait everywhere and caulking/foaming every place we could find. Week 1 we kept seeing them but when we did we were careful to caulk up where they were coming from/running to. By week 2 we were seeing fewer and smaller ones. By week 3 it was only tiny ones and I am delighted to say I haven't seen one at all in week 4! Thank you, thank you, thank you! One helpful tip I read elsewhere is to get a good spray bottle and fill it with soapy water - that will freeze them in place until you can smash them (sorry, gross) - very helpful if they're running up walls or in hard-to-reach corners.

KathySkid (author)2016-11-25

Will this method work for silverfish?

Ninzerbean (author)KathySkid 2016-11-26

I don't know, never tried it but if you do and it works please let us know.

Zaloma (author)2016-11-10

Hi help please I did the remedy but roaches are appearing more and more I did it yesterday and I found more than six alive roaches in the kitchen. That was disgusting

Ninzerbean (author)Zaloma 2016-11-10

Did you skip any steps? You spray-foamed under the sinks? Got into all the switchplate covers, etc. I only ask because you should have immediate results of seeing only dead roaches. Is there a nest inside - meaning you have German roaches - that you have not found? Is everything in plastic, no cardboard anywhere? Yes, that is disgusting, I feel for you, I just don't know what to say other than to make sure you did all the steps, it take a good 4 hours to do a small house.

Zaloma (author)Ninzerbean2016-11-10

I did all the steps yesterday. I mixed two cups of boric acid with one cup of flower, next, I put Coran syrup to make a past like pinaut. Then I did small balls I put them every where in my kitchen behind the fridge, every where in the kitchen. I found 7 german adult roaches and a lot of baby german roaches I am really concerned. Please please please please help me I am crying. I ca not believe how I cooked dinner it was so taught for me to be in the kitchen and meet a roach every 5 minutes. Now I am thinking about how to be in my kitchen tomorrow

Ninzerbean (author)Zaloma 2016-11-10

The purpose of the paste is to stick it to places that are out of the way and where roaches go - like the backs of your drawers in the kitchen, on water pipes under the sink, on top of doors, behind picture frames... I think you need to re-read step 7 to see all of the places to place the bait. I don't know why you made balls of it. You must first see if there is a nest in your house and clean out where they are living to get them under some sort of control first. Just baiting your kitchen won't help, you need to bait the whole house, you need to get inside the walls, you need to clean everything really well and if you think there are roaches in the kitchen find out where and deal with that first. I'm sorry I can't help you anymore than that, I know how terrible this is. Try reading a few hundred of the comments and see if you can glean any more knowledge from them for your situation. German roaches are very hard to get rid of because they live inside vs outside. You must get rid of everything they eat such as cardboard.Your vacuum will become your best friend. It takes a lot of work, but it will pay off in that you will get rid of the roaches. But you must bait the whole house, not just the kitchen.

I just moved to New York. We rented an apartment of one bedroom. But I have a problem. I hate roaches and can't stand them. I sometimes see tinny ones, but the problem is I cannot even kill them. If my husband is home I would cry and tell him please kill it. But if I am by myself I would run to the room. I have seen them most behind the fridge and in the bathroom. I am about to use your remedy. I wish I will get rid of them as soon as possible. I am really suffering from them. They cause me to be stressful all the time. Today I bought the ingredients, and on Wednesday I will do it. Thank you so much.

Aw Zaloma,
I know how you feel, I really do. The only advice I can give you is that you have to put it in perspective - think of something much worse you would have to do, then trade that thought for killing a roach. If you put it in perspective you will see that you CAN do it. The first few are really really hard, but I promise it does empower you and you will become stronger than a roach.

Think how much you do not want a very small bug to have this sort of control over you. You can do it, I have faith in your abilities to see the larger picture. There are literally millions of people in the world who would trade places with you and live in a one bedroom apartment in the coolest city in the world (besides Tokyo) in exchange for dealing with some small bugs once in awhile, because where they live there are roaches every day, every hour of every day of their lives.

And the sooner you bait your apartment the sooner you will be roach free. Promise.

It's been a while that I've posted to this but I would like to say it's been almost 2 years ROACH FREE! Everyone is different maybe mine wasn't as infested as others. I know some people need to redo treatments every 6 months or so. I was at my breaking point when I found this and after trying so much this was my last hope. I had just moved in to my new apartment and there was roaches everywhere on the walls in cabinets everywhere. I cried for days trying everything I could to fix it. So I went on google and found this beautiful post. I did EVERY SINGLE STEP. It took over 4 hours to do a three bedroom two bath apartment. I put that stuff everywhere! And I found roaches here and there but DEAD. And since then I haven't seen any since. Please read everything and do ALL the steps. It will give you back your sanity. Thank you so much again my children and I are forever grateful!!!!!!!!

Dear Tasha,
Thank you so much for taking the time to write - I am so glad you are roach-free. I know what a relief that is too.

Thanks Zinzerbean for getting back to me about the caulking. I was able to bait every single outlet and switch in the 3 levels of the house this past weekend because I didn't need to do the caulking. I'm not sure where I picked that idea up - maybe in the comments somewhere... I baited on door frames in the kitchen and bathrooms as well. We had our exterminator come last week (after being out here 6 weeks ago) so I haven't seen any but I closed the AC vent in the kid's bathroom as the large ones were coming in through there. The exterminator told me he would bait one switch plate in each room (big whoop). I still went ahead and did all of them, including the ones that had the magic peanut butter from the exterminator. Many of the electrical boxes were dusty and that it was hard to find a clean area to put the bait down. I halved the recipe and still had a bunch of bait left over that I put in the attic near where I saw a ton of cockroach poop. The tree guy comes out on Wed and I'm really hoping that, along w/the baiting will help take care of this issue. I need to go in the attic and remove the insulation from around the HVAC vent going into the kid's bathroom to see if I can foam and/or tape any holes shut. Another thing I do is use packing tape - I put it around the attic access door (as there is a hole near the edge) and over the outlets in my daughter's room where I saw the poop. Not sure if it helps in reality or just helps me sleep better so I don't worry what's coming out of those holes. Thanks for all your help!

Wow KathleenA21, you have been busy. What a horror story about the AC vent - but it could be good news - there is a leak in your duct work somewhere - air is getting in which causes condensation which causes roaches to come have a drink. Having a leak in your ducts is a waste of money so get a duct person - HVAC to take a look - or you can do it yourself - there must be videos on how to do an inspection. In my house it means getting under the house and no way am I going there - BUT there is special metal tape to use on the ducts - much better than packing tape. Its like really heavy duty tinfoil but sticky on the back. Cool stuff.

I'm in a similar situation to Kathleen, i've read articles and how-to's with similar instructions (it all comes down to the boric acid, prepared in a variety of fashions). This one, is by far the best, the comments, and your "part-time job answering them" have inspired me. I plan to buy the stuff tomorrow.
-Will be posting with results a couple weeks from now.

But, for now, just wanted to say that the "heavy duty tinfoil" is simply duct tape. The Duck brand has totally confused the country - maybe world... Duck tape, is just sticky cloth. Duct tape is what is used in the HVAC industry. If you try and tape a duct with Duck tape, it will start to degrade quickly and be useless within a year.

Hoping you still check comments - we just sold our home and bought a new home. Previous owners were pest control workers, so I know the new home is bug free, as was our previous home. The problem is that we were in between the new home and the old home for a bit and moved most of our stuff to storage for a month while we moved out and moved in. We thought the storage was nice and clean, boy were we wrong.

We found dozens of baby German cockroaches and a few adults in my husband's dresser and a few here and there on the ground. We have bombed (several times), baited, and sprayed the storage unit. But the problem was we had already moved a few things over before we realized there were bugs, like our couch.

The stuff we've moved was just in the garage so we baited some sticky traps for a few days and no sign of any bugs, so we moved the couch inside, as well as a few other things.

Today, we found a baby/juvenile roach in the basement family room where that couch is. I put three of these "treats" in the basement, one in the kitchen, and two in the garage where the rest of our stuff is.

Since it's our stuff that has roaches and not our home, do you think this will be good enough? Should I do more or see if they become an issue first?

Also, these were made with borax, as that's all I could find. Will it still work?
