National Pollutant Discharge Elimination System (NPDES)
Napa County Mosquito Abatement District (NCMAD) is currently applying adulticide and larvicide materials as a part of its Integrated Vector Management program to control mosquitoes, rodents, and yellowjacket nests. All products used by NCMAD are EPA registered public health pesticides. Applications of these products are conducted by state certified mosquito and vector control technicians in accordance with label requirements and NCMAD’s best management practices. Click here for more information about the pesticides used by NCMAD.
Applications will continue throughout the year, as necessary, for in-ground yellowjacket nests and at various sites providing mosquito habitat (e.g. roadside ditches, flood control channels, storm detention basins, catch basins, tidal and freshwater marshes).
This serves as the NCMAD notification for pesticide application under the NPDES permit. For more information contact us at 707.553.9610.
