Mosquito Control Section


The Delaware Mosquito Control Section provides statewide services to more than 880,000 residents and more than 2 million visitors annually to maintain quality of life and protect public health by reducing the possibility of mosquito-borne illnesses, such as West Nile virus.  Our employees focus on controlling larval and adult mosquito populations and treating mosquito breeding habitats. Mosquito Control uses the latest Integrated Pest Management approach – source reduction and the judicious use of insecticides.

    We’re not just about mosquitoes….

    The Mosquito Control Section is also active in projects to restore and enhance wetlands habitats. One of our major projects is the Northern Delaware Wetland Rehabilitation Program, a collaborative partnership between DNREC’s Divisions of Fish & Wildlife and other natural resource agencies. Together, we’re working to restore up to 10,000 acres of degraded urban wetlands along the Christina/Lower Delaware River corridor.

    We also work to reduce mosquitoes while improving habitat resources for fish and wildlife through our Open Marsh Water Management (OMWM) efforts, and management of coastal marsh impoundments for tidal exchanges, water levels and microhabitats. To learn more about Delaware OMWM, please read "Guidelines for Open Marsh Water Management in Delaware's Salt Marshes" published in the journal Wetlands and “Open Marsh Water Management in Delaware: 1979-2007” published in the Proceedings of the New Jersey Mosquito Control Association.
