VIRGINIA GYPSY MOTH AERIAL TREATMENT SCHEDULE

The Virginia Department of Agriculture and Consumer Services and USDA Forest Service are cooperating in the aerial application of Bacillus thuringiensis var. kurstaki (Btk) and 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 early caterpillar development (April-May) for Btk and the emergence of the adult gypsy moth (mid-May to late June) for the mating disruption pheromone. 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. Due to unpredictable weather conditions, the specific treatment dates cannot be determined until just prior to 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 or call 804.371.2175 for a pre-recorded message with daily treatment schedules. The dates below are subject to change.
