This treatment is in addition to the planned adulticide treatment for Williston and Watford City to be conducted by the U.S. Air Force Reserve (USAFR) as these areas located outside of the USAFR treatment zones. The USAFR will likely take place on Wednesday, July 16, near sunset, weather and conditions permitting.

The WCVCD uses Zenivex E20 for adult mosquito control treatments (adulticides), which contains the active ingredient Etofenprox. Zenivex E20 is a product approved for use in residential areas by the Environmental Protection Agency (EPA).

To avoid mosquito bites, residents are advised to take extra precautions when spending time outdoors during the hours of dusk to dawn. Wearing long sleeve tight knit shirts and long pants, limiting time outdoors during these times, and using a mosquito repellent such as DEET, Picardin, or oil of lemon eucalyptus are good actions to take to prevent bites. Residents can help prevent mosquito re-population by eliminating standing water on their property.
