Weed and Mosquito

The Division's primary functions are the management of mosquitoes and noxious weeds throughout Cascade County. These functions are facilitated through integrated management techniques involving the use of herbicides and insecticides, biological control agents, promotion of land use practices that prevent or mitigate problem development, and provision of education and public awareness programs. The Division works with and assists landowners in the areas of problem identification and mapping, management plan development, grant application, and the acquisition and distribution of biological control agents. The Division also has portable sprayers available for county residents to rent for noxious weed control.

The Weed and Mosquito Division had thirty-two (32) employees during 2018. Of these employees, three (3) are full time, leaving twenty-nine (29) as seasonal/temporary employees. Of the full-time employees, one (1) is the Division Superintendent and two (2) are field supervisors who work in both the weed and mosquito areas.
