Description The Department of Ecology monitored methoprene concentrations in surface water samples from Grant County Mosquito Control District No. 1 during the 2005 application season. Methoprene (Altosid) is permitted for use to control mosquitoes in Washington State. It mimics a juvenile growth hormone, preventing mosquito larvae from maturing into adults. Unable to metamorphose, the mosquitoes die in the pupal stage.

The Water Quality Program wanted to know what kind of methoprene concentrations occur when there is treatment and to verify that the concentrations are not a significant concern for aquatic life.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
