The EPA Regulates Mosquito Control Insecticides
The Environmental Protection Agency (EPA) has regulated mosquito control through enforcement of standards instituted by the Federal Insecticide, Fungicide, and Rodenticide Act. This legislation mandates extensive testing and documentation for public health insecticides, prior to their registration and use. These requirements are among the most stringent in the federal government and are met through research by established scientists in federal, state and private institutions. This process ensures that the public health insecticides available for mosquito control do not represent health or environmental risks when used as directed.

Cocobear is a liquid that is applied to the top of the water column by a pump up sprayer.
