Washington County Mosquito Control is responsible for managing mosquitoes by an integrated mosquito management (IMM)strategy. Integrated Mosquito Management is a comprehensive mosquito surveillance and control strategy that utilizes available mosquito control methods singly or in combination to reduce their numbers to tolerable levels while maintaining a quality environment.
Key elements to the mosquito control program:
- Provide public education and outreach in the community
- Conduct mosquito surveillance using a variety of field and laboratory methods to monitor mosquito populations and mosquito-borne diseases
- Use biological and/or chemical control methods when conditions supporting mosquito production cannot be removed or altered sufficiently
- Distribute mosquito fish to Washington County residents for use in their ornamental ponds, water troughs and other potential breeding areas
-
Coordinate surveillance and control efforts with other local, state and federal governmental agencies
