DNR Suppression Program
Counties may apply to this program to be considered for spray treatments if gypsy moth populations are at damaging levels. If you would like your property considered for spraying because of high gypsy moth populations, contact your local and county gypsy moth coordinators to make your request.
DATCP Slow the Spread Program
This program sprays to slow the spread of gypsy moth populations to the west. Traps are set in counties where we expect to find small, isolated populations of the pest spreading westward. Trap information helps determine spray locations.
