6/6/2023: The Williston Vector Control District is tentatively scheduled to conduct a ground adulticide treatment for Williston spray blocks 3, 4, 8, 9, and 10 between Wednesday, June 7 and Friday, June 9. Treatment will take place near sunset, weather and conditions permitting. Updates will be posted on this page.
Williston Vector Control 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, citizens 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. Citizens can help prevent mosquito re-population by eliminating standing water on their property.
