Registered Pesticides For Mosquito Control

Registered Pesticides For Mosquito Control
To allow pesticide users to have more choices of less hazardous pesticides in mosquito control
and to prevent the development of resistance to a particular pesticide, the Agriculture, Fisheries
and Conservation Department has registered 5 new pesticides and relaxed the formulation and
concentration restrictions of 3 registered pesticides. A listing of some registered pesticides that
can be used for outdoor mosquito control is presented in the table below for easy reference.
