The Virginia Department of Agriculture and Consumer Services and USDA Forest Service cooperated in the aerial application of the spongy moth mating disruption pheromone in the counties listed below. This mating disruption pheromone application was conducted using fixed-wing aircraft from daybreak until evening on June 12th, 2025. At this time, all Slow The Spread (STS) aerial spray treatments in Virginia are complete for the year.
The timing of the aerial treatments is scheduled to coincide with the emergence of the adult spongy moth (mid-May to late June) for the mating disruption pheromone. Weather conditions during spring and early summer will determine the rate at which spongy moth develop and is therefore a major factor in determining the treatment dates. Due to unpredictable weather conditions, the specific treatment dates cannot be determined until just prior to spongy moth emergence.
VDACS will monitor spongy moth development in 2026 and provide updates to the schedule below. Please check this webpage periodically to obtain future treatment dates for your county or call 804.371.2175 for a pre-recorded message with daily treatment schedules.
