The Virginia Department of Agriculture & Consumer Services and USDA Forest Service are cooperating in the aerial application of the gypsy moth mating disruption pheromone in the counties listed below. The application will be conducted using fixed-wing aircraft from daybreak to nightfall.

The timing of the aerial treatments is scheduled to coincide with the emergence of the adult gypsy moth, which normally occurs from mid-May to late June. Weather conditions during April and early May will determine the rate at which gypsy moth larva develop and is therefore a major factor in determining the treatment dates. Since these weather conditions are unknown, the specific treatment dates cannot be determined until just prior to adult gypsy moth emergence. 

VDACS will monitor gypsy moth development during April and early May and provide updates to the schedule below.  Please check this webpage periodically to obtain final treatment dates for your county.
