Mosquito Dunk

Six mosquito dunks per package are enough to keep your gardens and yards mosquito-free for months. Each dunk releases an effective larvicide (Bt Israiliensis) into standing water for up to 30 days. Disks treat stagnant water in birdbaths, flowerpots, gutters, and unused swimming pools. Mosquito Dunks kill mosquitoes before they get old enough to bite.
