Does Bleach Kill Roaches? Looking For A Roach Killing Alternative


Roaches are known to have resistance to some pesticides or insecticides, this has led many homeowners to so much frustration because nothing seems to work against these pests in their home. This is why many people are now looking for other products that they might be able to use against an infestation.

One of the products that many people are now suggesting that homeowners use to kill roaches is bleach. And while we might know how good bleach is when it comes to cleaning the household, removing bacteria and keeping things white, many of us are wondering if it can act like an insecticide.

Bleach does contain strong chemicals that can even cause irritations in humans. We know that in some occasions, bleach can actually harm the skin, the eyes, the mucus membranes and it can even cause breathing problems especially when used in very strong concentrations. So, does bleach kill roaches?

Does Bleach Kill Roaches?

Bleach can actually kill roaches. When they roaches ingest or come into contact with high concentrations, it is possible for bleach to kill the roach in a matter of minutes. This is especially true if you are able to use the bleach properly and to make sure that the roach will get fully drenched in it.

Bleach can kill roaches by causing a deadly reaction as soon as the roach ingests it. Bleach is also known to be able to kill the bacteria, viruses and parasites that might be living on or inside the roach. This makes it effective since it will not just kill roaches, it will also help you control the spread of infection.

However, there is a huge flaw to the bleach’s capability to deal with roaches. This is because while it can kill these insects, they are not actually efficient killers. This is why you might want to make use of the correct methods so that you can use this chemical mixture effectively against these gross and ugly pests.

How To Use Bleach To Kill Roaches

Bleach is very impractical when it comes to killing roaches. This is because the roaches need to ingest the chemicals first before they will suffer from a chemical reaction and die. Unfortunately, bleach is known to have a very strong and pungent odor that will surely discourage the roaches from drinking it.

This is why there are those that suggest that you try to use bleach to make a bait by mixing it with food items that the roach might find appealing. However, this might still not work because of the bleach’s strong odor. You can also try to make roach traps that will kill roaches by drowning in bleach.

However, you should know that these suggestions are very impractical. They will also not address the roaches that are nesting in inaccessible areas. By far, the most effective method that you can use is to put it in a spray bottle and spray it directly on the roach. But this cannot give you guaranteed results.

Should You Use Bleach To Kill Roaches?


While bleach contains chemicals that are strong enough to kill roaches once they ingest it, you should know that it is very hard to use it properly and get good results. Roaches do not like the smell of bleach and there is very little chance that they are going to eat or drink anything that even has a hint of bleach.

This is why I think that you might be better off trying other alternatives instead of bleach. While I do use bleach to clean my home, I think that I will only get frustrated if I try to use it to kill roaches. You can try to use professional-grade insecticides or boric acid if ordinary roach sprays will no longer work on them.

You should also know that bleach can discolor different surfaces. If you are going to use a spray bottle around the house, you might actually end up discoloring fabrics and furniture without actually making a kill. This is why I do not recommend this product at all for the elimination of roaches inside the house.

Bleach is a very popular product for cleaning pools, disinfecting the home as well as when it comes to making clothes white. While its chemicals are strong enough to easily kill a roach, the roach needs to ingest it first before you can expect to have results. This task is unfortunately, next to impossible.

This is because roaches would not even try to go near bleach, let alone ingest it. And while you might be able to spray it directly on roaches, there is no assurance that the bleach will be able to kill the roach right away by simple contact. This makes bleach an impractical choice for killing roaches at home.
