How to Use Baking Soda/Baking Powder to Naturally Kill Cockroaches


I recently discovered a container of baking powder that had expired in my kitchen cabinet. Instead of throwing it out, I decided to do something useful with it by creating a cockroach-killing powder.

That's right, baking powder and baking soda are cockroach killers - natural, non-toxic alternatives to poisonous commercial cockroach-killing formulas advertised on television.

**********

You'll Need:
- baking soda or baking powder
- any kind of granulated sugar
- empty container
- small, shallow containers or dishes (wide, plastic bottle caps work nicely)


Directions:
    1. Mix equal parts baking soda/baking powder with equal parts sugar.
    2. Place the mixture into your container of choice.
    3. Shake it up so the mixture is evenly distributed.
    4. Pour some of the mixture into the shallow containers/dishes.

To Use
:


Place the shallow containers of your cockroach-killing powder in corners and areas where you think cockroaches often roam. The sugar in the mixture will attract the cockroach to eat it, and the ingested baking powder/baking soda will kill the cockroach by expanding inside its stomach, killing them from the inside out. The container must be shallow enough for cockroaches to easily reach the mixture inside. Although this mixture isn't toxic to animals or children in such small doses, it's still probably best to keep it out of their reach since you don't want them touching or eating things cockroaches have come in contact with.




**********

I can say from personal experience that this powder mixture truly works. After I began using this mixture, I have found dead cockroaches in random corners of the house. This is a much cheaper and better solution to a cockroach problem than using commercial cockroach killers, as not only are they toxic to the environment, they also help create new generations of stronger cockroaches immune to numerous industrial poisons.

    1. Oh no! I'm sorry to hear that this isn't working for you. I only had a very minor cockroach problem, but it sounds like you have a serious infestation that perhaps a few baking soda traps won't solve.

      If there is anyway for you to get to the source of the problem, that might help. I imagine you already know that cockroaches are drawn to standing water, food and crumbs that are left out. Also remember to seal up the holes where cockroaches might be getting into your home. I've found this is usually through kitchen and bathroom drains, and in the spaces around pipes leading into the house. I also make it a habit to plug up the drains in my kitchen and bathroom before I go to bed, as cockroaches are most active at night and are able to crawl up through and around drainpipes to get into the house.

      I don't know if this will help, but it's worth a shot. I sincerely hope you find a solution to your problem soon!

    2. Ok well the theory of this is logical but I would imagine it would be hard to put enough of this out for a large roach problem. From the poster's comments I would venture this might be german cockroaches he/she is trying to get rid of they are notoriously bad once you are infested. Plugging drains is actually a really good idea. I haven't figured out how in the world to plug my shower drain. The tubs & sinks in the rest of the house are easy. I see asian roaches in this one bathroom each and every day. I am trying to figure out where this one particularly large one is really going when it disappears. But on the point of why baking soda works you are actually mistaken. The baking soda expands in the roaches stomach and kinda pops them open from the inside out. Its DE that cuts them and also kills them. DE is often the poweder that the pest control companies put behind appliances. I see roaches a lot also in my kitchen as well and our pest control company had coated behind my range and refrigerator with DE. But when they pulled out to check for tracks through the DE there were none. Now two other home remedies that I know of are shallow containers of cheap wine (though this won't work with cats at all, but I did want to mention it) and making a catnip tea to essentially wash your floors with. I have to say though this could also drive the prior poster's cats nuts too though. But with cats around you really have to be careful what you use to treat the roaches. Roaches cause all sorts of asthma problems and the cats could be effected by this too. If you can find where the roaches come out of and it is a place the cats don't get to the same location I would try putting DE there instead of the baking soda & sugar. The other thing I can think of is maybe one of the DIY pest control places sells a IGR (Insect growth regulator). It is used sparingly and only in places you are sure that the roaches are crossing so sadly you do have to watch the nasty little beasts to figure out where they are going and came from. You should probably also ask them how to safely apply DE when you have cats around. DE may also help with bedbugs. But the big problem with bedbugs unless your bed you sleep in has a proven mattress protector to keep out bed bugs and you get rid of any upholstered furniture you may bring your problem with you.

      But I think I would highly consider moving. It sounds like the place you are currently in needs to be seriously bombed and left alone for a long time to kill everything. I wish you luck.

    3. Thanks Bennett Leve! You are right about how baking soda actually kills cockroaches, that was my mistake. Thanks for correcting me, and for offering other solutions to cockroach problems as well.

      And yes, for very serious cockroach infestations, a little baking soda probably isn't going to do the trick - unfortunately. But I don't think it comes to anyone's surprise that they're incredibly resilient little bastards.

      As for your shower drain, if it's the kind where the drain is flat and in line with the bottom shower floor, without any actual "cup" to plug, then you have the same problem I do. What I do is put a rubber mat over the drain and put something heavy on top of it. It's not pretty, but it does the trick.

      Caulking is also something everyone might want to try to plug holes around drainpipes and around cabinet crevices to keep cockroaches out of the house.

    4. My roommate and I decided to try and clean some odor out of our apartment that the high humidity and rains have brought out. We put baking soda all around the carpets through the apartment and let it sit a couple days. I didn't know it would effect the roaches. This place has been over run with them from day one. We have tried everything you can imagine. I haven't seen a single one since we put out the baking soda and he said he has only seen one. It's been two weeks now, My cat has been sick off and on for a while now but with the bugs gone he is getting better. We have decided to vacuum it and replace it every few days. We both would rather walk on backing soda then live with bugs. Try putting it all around that for a while and it might drive them out.

  3. I live in a 34 yr old building in Georgia( 8 stories) ! I am grateful for the baking soda tip. I am already putting it out all over. This building was recently completely renovated. I think it has disturbed these long time dwellers! I constantly clean up behind my husband! Wish me success. This is a roach here&there. I just don't see how they live here. I am a clean freak!

    2. I use eucalyptus oil in my Rainbow vacuum cleaner. When Hurricane Ike came through and flooded out neighborhood, it was terrible--mosquitoes, bugs, and especially mold and mildew.
      I was lucky that my house didn't flood although I had to come home in a boat. However, part of my garage flooded. I discovered an antique book from my great aunt that had not been put up high (I didn't know it was in the garage with a box of books). It smelled horrible--the same smell that permeated our neighborhood. I discovered that when I put a cotton ball with eucalyptus oil in a plastic bag with the book (not touching book--but in a little open plastic bag), then sealed up the book--all the mildew odor was gone. I tried it with other things in my garage and it worked.

      Once many years ago, I moved into an apartment that was infested with cockroaches (those little ones) and they were even in the refrigerator--and the apartment had already been exterminated a couple of week before we moved in. I put boric acid around all the walls and in all the cabinets--every wall. The roaches were gone in 3 days--and I did not see one again. I left the boric acid down for about two weeks, then vacuumed (with the water filtering vacuum cleaner)--but reapplied in kitchen and cabinets--and around porch. I did not have trouble with roaches again while I lived in that apartment. (I used a dust mask while working with the boric acid because I'm sensitive to dust.

  5. I have heard peppermint oils help get rid of the roaches is this true?

    1. I have heard that! Never tried it as a cockroach deterrent myself, but in my experience, essential oils don't seem to last very long when sprayed into the air or into corners of the house. So my worry would be that I would need to constantly reapply the peppermint oil to make it work. If you try this, please post another comment and let us know whether it was effective!

  6. This sounds like a good solution. I just have one question. Won't the sugar bring ants?

    1. I believe this mixture is just as effective on ants as it is on cockroaches. Unfortunately, I can't say for sure whether this would eliminate more ants than you would attract. But I only have a cockroach problem, not an ant problem, and I haven't noticed any signs of ant infestations after laying out these traps ... so far.

    2. If you use powdered sugar instead of granulated it will kill ants as well for sure.

  9. When we lived in Jordan my Mom would put about a 1/4 cup of kerosene down the drains every so often and during bad seasons but some in the water when she washed the floors as well. The houses thier are made of cement however so I would not recomend this for a wooden house! It did work though.

    ReplyDelete
    Replies
    1. I would strongly advise against doing something like this. Not only is kerosene highly toxic to humans and animals, it is very bad for the environment and dangerous if you pour it down the drain. I have no doubt that this method probably works, but in the interest of protecting the environment in as many ways as we can (and protecting your health!), I would encourage you to try greener alternatives in combating pesky cockroaches!

  11. I use equal parts of baking soda and baking powder with a sprinkling of powdered sugar and it really does keep them away. In the rainy season my neighbors complain of ants coming in, yet I do not have the problem. I live in an apartment complex in Texas where roaches thrive. My son is a pest control man, he initially could not find any cockroaches! with this treatment along with a cap full of bleach in my dish water that I wipe the entire kitchen counters down with. He was telling me that the reason I do not have roaches or ants and my neighbors do IS because of the soda/powder mix ~ it pops them. Just thought I'd give ya'll my thoughts and encouragement.

  12. HI, I TRIED THIS MIXTURE, AND IT DID NOT WORK FOR ME. I ALSO TRIED BOILED EGG YOLK AND BORIC ACID, AND PEANUT BUTTER, BAKING SODA AND BORAX. HAS NOT WORKED. I HAVE TRIED THE HOUSES, STICKY BAITED TRAPS AND THE GEL. I HAVE VACUUMED THE CABINETS, AND FRIDGE. I EVEN USED RAID ON BASE BOARDS. TO NO AVAIL, I STILL HAVE ROACHES. I HAVE HEARD THAT IF YOU PUT BORIC ACID ON BASE BOARDS THEY WILL WALK IN IT AND CLEAN THEMSELVES UP AND EAT IT AND DIE. I AM WORRIED TO USE THIS WITH BUT I PUT BAKING SODA AROUND THE HOUSE, AROUND THE LIVING ROOM, BATHROOM AND KITCHEN, BEHIND THE COUCH AND SPRINKLED ON COUNTER TOPS AT NIGHT, DO YOU THINK THIS WOULD WORK, I AM SO TIRED OF THIS. I THOUGH IF THIS WORKS THE ROACHES WILL DIE AND MY COUNTERS WOULD GET REALLY CLEAN FROM THE BAKING SODA. YOUR IDEAS WILL BE HELPFUL . THANKS

      The yellow Listerine works as a spray directly on them to kill but not as a dettern . We even have loose geckos that have had babied yet still have them

      My dad is 83 don't cook much yet still has roaches so disgusting

      Sprayed everything known

      N we are very sensitive to the chemicals

      I used to buy a white n red can at Kroger's that did not have a chemical smell can't find it now

      I'm not sure what the heck works wish I knew

      I have a clean home n I have some hate them

      Having a clean vs dirty home doesn't cause roached I've seen very clean homes w roaches

    Yes it worked. Takes a long time. I'm almost to four weeks. But, you can see the amount of roaches decrease steadily. Lots of dead ones in the beginning. Still am killing a few every day, nothing like I moved into. They were everywhere even after bombing twice. One to three a day now. Doesn't bother the dogs a bit and that's the best part. Also someone on another site said to fill a spray bottle with 1/4 cup or so of dish soup and fill with water to spray them. Don't know if it kills them or not, but it slows them down so you can wack them. I think I'm winning ! Best of luck and thank you, Deb

    1. The spray bottle with dish soap and water really works, but you have to run faster than they can. If you are able to give them a few squirts of solution, it will suffocate them immediately and kill them. The only downside to this is you really don't want them to die immediately since it is preferable they return to their nest and kill the entire nest.

      Delete
  14. for drains that you cannot plug up, pour dish liquid down the drain at night. Just a squirt or two and also squirt it around the drain. This keeps them from crawling out into your home from the drains. They breathe through the body and dish soap suffocates them!

  17. Give the Baking Soda/Sugar Mixture a little more time. If you have a Serious problem it may take a little longer to work, its not an Instant Kill Formula. Just keep sprinkling the Mixture down in corners and areas where Roaches are seen. Within 30 Days you will be Roach Free. Using this mixture is Safer than using Chemicals. You also need to Monitor your indoor Humidity. High Humidity will attract Roaches and Ants. I know its hard to keep waiting, especially when you see them running in all directions. Be Patient. Do You live in a Northern State?

  22. My daughter and kids moved into an apartment. Roaches were everywhere. There was supposed to be an exterminator come every week, but he didn't. When I went to visit, I took matters in my own hands, and sprinkled Baking Soda on all baseboards and plugged up drains nightly. In the last 2 months, we have seen less than 15. I know that its working, because one of the traps behind her fridge has several roaches on it that look like they are close to bursting. Yaaay baking soda.

  23. I have been using Diatomaceous Earth after my landlord has sprayed many many times. The DE seems to be finishing them off. I have it on my counters and that seems to be where they land. I read here that you can put it behind the stove and fridge. I'll do that too. Our neighbors aren't very clean and the roaches come in from that side of the house. Others in our neighborhood have a problem with them, too. It's a shame we all can't just be free from the filthy things!

    1. Although baking soda and baking powder are considered dangerous to dogs, he/she would have to ingest an incredible amount for it to have a toxic effect. It's best to consult your veterinarian to determine exactly what it was that killed your dog.

      That said, I'm so sorry for your loss and I hope you get some closure about what happened to your pet.

    2. So this is what you need to do, Mix the Baking soda with an equal amount of sugar and use a little bit of water to make a past. Fill the bottle caps with them and put the caps in discreet corners where often often see the roaches. Clean all the surrounding areas either with a bleach solution or a solution with water and White Vinegar. The vinegar is like acid to the roaches. The water/Soda/sugar solution is irresistable to them...so much so, that they let off a pheromone to tell the rest of the colony where the food source is.

      They will keep consuming the mix until their internal organs explode because of the gases and that leads to death.

      I tried it as a last resort to paying for pesticides/bug deterrents. I even used to blob in the middle of carpet tape so that they get caught in the sticky bit. To ensure that it really works you have to make sure there are NO OTHER FOOD SOURCES ANYWHERE

      4 weeks on not a single cockroach.

      Delete
    3. Sugar/Baking Soda/Water.... That's the mix you should aim for.

      Delete
  25. And just to add....

    The sweet smell of sugar entices the roach out of hiding to eat it, as well as the baking soda. Then, when the roach drinks water, the baking soda reacts, creating gas inside of the roach which causes its stomach to burst, killing the roach. Since other roaches feed on dead roaches, they also acquire the fatal substance and subsequently die. Follow these steps to use sugar and baking soda to kill roaches in your home.

    this does take a while but it does work. just make sure you wipe down the surrounding areas with bleach or a solution of water and white vinegar if you can bare the smell. cockroaches leave traces of pheromone for others to follow when they find a food source. If you don't want to see them climbing walls or scuttling in specific areas, wipe does areas down and restrict your bait to areas where you may not see them.

  26. I've seen this working. And it takes some time depending on how bad it is. Roaches are also investigative. If you make the mixture into a paste if the roaches check it out, even if they Dont eat it right away, they will when they clean their antennae and front legs as the paste is very sticky.
