If you want to eradicate mosquitos in your area without having to call for extra help, try mosquito dunks. The circular dunks include BTI, a specific pesticide that is harmless to people, pets, and wildlife. Place the dunks wherever water accumulates, and you’ll be rid of the pests for the entire season. The dunks kill mosquito larvae before they mature into biting adults. “It’s very effective and safe for everything,” Bennett says.
