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.


Mosquito Samples Test Positive for West Nile Virus

West Nile virus has been found in multiple locations throughout the District. Just because a section is not "red' does not mean WNv is not present; the District does not and is not capable of taking samples from every part of the District. One should assume that WNv is active within the mosquito population regardless of where you live or play.

Additionally, Culex pipiens (a species that we have in our District that is capable of transmitting WNv) will be looking for areas to overwinter as Fall approaches. The combination of temperatures and diminishing daylight hours triggers the response in the species. Culex pipiens will look to overwinter inside structures (barns, sheds, garages, homes, etc.). If you should notice mosquitoes in your home or garage suck them up with a vacuum or shop-vac.

Samples of mosquitoes tested in-house by Benton County Mosquito Control District have tested positive for West Nile virus. Please refer to the map below.

You are the best line of defense against mosquito bites. The District advises using precautions to limit exposure to mosquitoes.

  • Repellent; your best defense against bites
  • Evening & morning have higher mosquito activity
  • Pour out, standing water weekly
  • Even one bite can cause illness
  • Long-sleeve shirt & pants

We highly recommend that you use (if possible and appropriate) a Centers for Disease Control (CDC) approved repellent listed for mosquitoes. You can learn more about repellents at this link; Repellents.
