Will Bleach Kill Bees?

Bleach does not kill bees, unless the bees are drowned in bleach liquid. Bleach is a pesticide, not an insecticide, which is required to kill bees effectively. Bees may die from being submerged in any liquid, but bleach is not intended for killing insects.

Bleach is effective at killing bacteria and sanitizing homes, public transportation and hospitals. When mixed with other common household cleaners, such as ammonia or Drano, bleach can become a volatile chemical that produces toxic gases and explosive substances akin to rocket fuel. In addition to being found in liquid form, bleach is found in powdered household cleaners, including Ajax and Comet.
