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.


West Nile virus

West Nile virus (WNv) had been confirmed in mosquito populations within our District.

Benton County Mosquito Control District (BCMC) routinely collects mosquitoes in traps for the purpose of monitoring mosquito populations and testing for the presence of mosquito-borne illness.  BCMC has the ability to perform in-house testing of mosquito samples, though some samples may require additional testing to confirm/deny the presence of WNv.

Zika Virus

Zika virus has been getting a lot of attention lately.  There is much we don't yet know about this virus, but presently there are two factors that should be considered with regards to Benton County Mosquito Control District residents and visitors:

(1) The mosquito species of primary concern, Aedes aegypti, is a tropical species primarily.  It has been found domestically in the southern United States.  Another species of concern, but not as competent a vector (transmitter of disease) for Zika is Aedes albopictusWe do not have either species in our District.

(2) The Zika virus needs to be present for the transmission cycle to occur.  There is no evidence that Zika virus is naturally present within Washington State.  Cases being diagnosed in the US have either been travel related or sexually acquired from someone that has traveled to an infected region.

There are many emerging theories about the Zika virus; we will update information as needed.  If you would like more information on Zika Virus related topics, please visit the Centers for Disease Control (CDC) website: CDC - Zika virus
