Thank you for visiting the Website for the Benton County Mosquito Control District. Since 1969 we have been providing mosquito control services. We hope that this website answers your questions and increases your knowledge of mosquitoes and mosquito control activities. If you can't find what you're looking for, please feel free to contact us.
The Benton County Mosquito Control District is dedicated to responsibly improving the quality of life and increasing public education in our area. The District accomplishes this by utilizing Integrated Pest Management (IPM) strategies. IPM is designed to utilize cost-effective control measures to reduce mosquito populations and the diseases they potentially carry, while being environmentally sensitive.
Communication and cooperation with property owners, residents and governmental agencies are critical components in the effort to reduce mosquito populations. Benton County MCD strives to be open and responsive to our community.
Aerial (Plane-Based) Spraying for Adult Mosquitoes (Sunday, July 24th) - Completed. Thank you.
Certain areas within the Benton County Mosquito Control District (the District) have been showing sustained West Nile virus (WNv) in the mosquito populations. In an effort to reduce these mosquito populations and limit exposure to the WNv, the District will be using a contracted flight company to perform adult mosquito applications with a fixed-wing plane. Spraying can begin at sunset and will take a couple of hours (there are 3 blocks; Richland, Grandview/Prosser area, and NW of Mabton). Higher winds, rain and environmental conditions can delay or prohibit spraying all together.
