SUMMIT MOSQUITO DUNKS 6 PACK
Use Summit Mosquito Dunks in ponds or standing water to kill mosquitoes and black fly larvae for 30 days or more. While the Mosquito Dunks float, they slowly release a long-term biological mosquito larvicide, BTI, killing the larvae before they hatch into adults. This biological mosquito control is safe for use around children, fish, pets or wildlife. Treats up to 100 square foot of water surface.
