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. This is especially useful in Taiwan, where cockroaches can become a really big nuisance.

**********

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, 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!

  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?

    ReplyDelete

    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.

    1. Baking powder probably works too, but I think baking soda might be more effective, since it is a stronger leavening agent.

  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.

    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!
