Rain Barrels in Georgia

Mosquitos love sitting water, so don't be a sitting duck! These EPA-approved mosquito dunks release Bacillus thuringiensis subspecies israelensis (B.t.i.), a bacterium toxic to mosquitos as well as Black Fly and Psychodid Fly Larvae. Mosquito dunks can be used in rain barrels, ponds, bird baths, water gardens or almost anywhere that water accumulates! Safe for the family and the environment. One dunk will treat 100 square feet of water for 30 days. Dunks may be broken to treat smaller areas.
