The numerous ways to use bleach seem endless. It is commonly used around households as a cleaner, but a quick internet search will reveal many uses beyond killing germs.
A common question we hear about bleach is how effective it is at killing or keeping away pests. Today we are going to explorer specifically “does bleach kill roaches?”.
Yes, bleach does kill roaches. The bleach either needs to be sprayed onto them or the they must ingest the liquid. This may seem like a quick and cheap solution to eliminate roaches, but please consider the following first.
While cockroaches are notorious for feasting on just about anything, it is improbable that they will swallow bleach. This includes food, for example, that has been soaked in bleach and left out over night as bait. Even if a few roaches were to swallow the bleach, it likely only going to eliminate a tiny percentage of the household roach problem.
Exposing the roaches to a high-strength dose of bleach will kill them. Their bodies typically need to be thoroughly soaked in the bleach to effectively kill them.
Drenching only the roaches that you see is not a good solution to a roach problem since numerous other roaches are likely hiding in the immediate area. In other words, if you kill one or two via the bleach method, you really are not attacking the source of the roach problem, which is the nest.
