I don’t know about you, but when I see a cockroach, my first instinct is to get rid of it. Using bleach to kill a cockroach (Blattella germanica and Ectobius vittiventris) seems like a good idea for many people. But does bleach kill cockroaches?

Bleach will only kill roaches if they drown in the stuff. But that’s unlikely since cockroaches won’t go near bleach because they hate how it smells.

Unlike effective pesticides, bleach doesn’t stick to roaches. Therefore, cockroaches won’t ingest bleach through grooming or spread it to other cockroaches in the area.

So, to put it mildly, bleach is an ineffective pest control solution. You can’t even use bleach as bait because roaches dislike the smell of bleach.

Bleach is also potentially dangerous to humans and pets, so you don’t want it in areas where children and pets have access to it. And due to its corrosive characteristics, bleach can easily damage any surface you apply it to.

Can bleach kill roaches?

Bleach can kill roaches. But using bleach is not an easy method to eliminate cockroaches from your house. If you want a practical way to kill roaches, you need to use chemical or natural pesticides to get rid of your cockroach problem.

While traditional roach baits kill roaches through touch, bleach only works if these pests drown in the toxic solution.

Bleach is effective for killing many types of molds, bacteria, viruses, algae, and mildews, but it’s not an effective pesticide. Realistically, bleach is a household cleaning chemical, not a pesticide.

Due to its pungent smell, bleach doesn’t work as bait. Its strong scent will repel roaches in the area, but it won’t kill them. For a pesticide to work, it can’t repel pests. If a solution repels roaches, they won’t come in contact with the stuff.

To make bleach even more ineffective as a pest control measure, roaches don’t spread it to other roaches in the area. So, even if you kill one roach with bleach, that’s where it ends. So, you have to use bleach roaches one by one, which is an impossible task when your home may have thousands of cockroaches hiding.

Therefore, bleach is a fail when it comes to eliminating roaches from your home.

Cockroaches are nocturnal pests which means that these pests are most active during the night. But, even if you see one roach during the day, there may be a serious roach infestation in your house.

Dark areas, garbage, leaky pipes, left-out food, and cluttered spaces draw cockroaches indoors. Once inside, they make their presence known through unpleasant smells and stains and the spread of pathogens once inside.

There are many signs of a cockroach infestation. One day you might walk into your kitchen at night, flip the light switch and find a single roach on the countertop. Or, you might find entire ‘nests’ of cockroaches in your home one day.

Cockroach nests are where roaches congregate; they’re often dark, damp, warm, and close to food. Roaches leave behind feces and stains, shed exoskeletons, egg cases, and bad smells wherever roaches go.

What’s worse, many people have allergies to roaches, so your body may warn you before seeing these pests.
