What is a Mosquito Dunk®?
A Mosquito Dunk® looks like a small, beige donut which floats on standing water. As the Dunk® slowly dissolves, it releases a bacterium which is toxic to all species of mosquito larvae. Mosquito Bits® are a granule that contains the same active ingredient found in the Dunks®, but unlike the Dunks® the Bits release the larvicide immediately.
What is the active ingredient in Mosquito Dunks®?
The active ingredient in Mosquito Dunks® is Bacillus thuringi-ensis subspecies israelensis. (B.t.i.). B.t.i. is a bacterium that is deadly to mosquito larvae but harmless to other living things.
How do Mosquito Dunks® work?
While floating, a Mosquito Dunk® slowly releases a long-term biological mosquito larvicide at the water’s surface. This larvicide gradually settles in the water, and while it travels through the water it is eaten by the mosquito larvae growing there.
Where should Mosquito Dunks® be used?
Just float a biodegradable Mosquito Dunk® in water troughs, koi ponds, birdbaths, rain barrels or any place where water collects and remains for periods of time. When female mosquitoes lay their eggs in standing water treated with a Mosquito Dunk®, the larvae will hatch and begin to eat the B.t.i. The B.t.i. will kill the mosquito larvae before they can grow up to become biting and disease-spreading adults.
