Full Answer

Bleach is legally considered a pesticide. The U.S. Environmental Protection Agency states that any bleach with a minimum of 5.25 percent sodium hypochlorite that kills bacteria and kills fungi is a pesticide. Mosquitoes need standing water to breed. The best protection is to drain standing water or to turn the objects upside down to prevent water collection.
