Mosquito Dunks provide long term, sustained, release protection - each Dunk continues to kill mosquito larvae for 30 days or more.

Used by professionals for more than a decade, Mosquito Dunks® have proven their value in destroying Mosquitoes - by killing the larvae before they mature into biting adult pests.

Made with natural B.T.I., Mosquito Dunks represent a major breakthrough for people and the environment when compared with the traditional toxic chemical approach to mosquito control.

Once a month float a Dunk in the Water Garden and every place water accumulates around your home - you'll be rid of mosquitoes for the whole season. Each Dunk will effectively treat up to 100 square feet of surface water regardless of depth. Dunks may be broken to treat small areas.

Unused and dried out Dunks retain their potency indefinitely. That's a great shelf life.

Kills developing mosquitoes before they become breeding, biting adults including those that may transmit West Nile Virus, Equine Encephalitis and Heart Worm Disease (in dogs and cats). Safe for plants and fish.
