In collaboration with the Williams County Vector Control District (WCVCD), the United States Air Force Reserve (USAFR) will be conducting an aerial spray mission over Williston between August 5, 2025 and August 8, 2025, if weather and conditions allow.
The large military aircraft will be flying at low elevations during the mission. Treatments will take place near sunset.
The USAFR will be using Trumpet with active ingredient Naled for the adulticide treatments. Trumpet is 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 during the summer months. 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.
