Each summer the Ohio Department of Agriculture deploys approximately 12,000 gypsy moth traps across the state to monitor movement and evaluate, detect or delineate newly established colonies. Proposed treatment areas are determined in the fall prior to the treatment year, based on the catch numbers and the available funding between the state cooperators. Products and application rates are determined based on the catch numbers and other environmental factors.
