Overview

Delaware regulates pest control through the Delaware Department of Agriculture (DDA), Pesticide Management Section. The state requires all commercial pesticide applicators to be certified and pest control businesses to be registered. Delaware's compact size and varied landscape, from coastal areas to suburban communities, create diverse pest management needs.

The DDA works to ensure pest control operators are competent in safe pesticide application, environmental protection, and effective pest management strategies while meeting federal EPA requirements.
