The Williams County Vector Control District (WCVCD) plans to conduct ground and aerial adulticide treatments across the County between July 10 and July 12, 2025, weather permitting.
Ground adulticide applications using DeltaGard are scheduled for the evening of Thursday, July 10 (tonight) in Trenton and Ray.
An aerial adulticide application using Imperium is planned for the evening of Friday, July 11, over Trenton. If weather conditions do not allow, the mission will be rescheduled for Saturday evening, July 12.
All treatments are weather-dependent and may be rescheduled to ensure effectiveness.
Both DeltaGard’s and Imperium’s active ingredient is Deltamethrin, and both products are approved for residential use by the Environmental Protection Agency (EPA).
Residents are reminded to stay at least 300 feet away from Vector Control trucks while fogging operations are in progress.
