Aquatic Mosquito Control General Permit

This permit is for government entities and individuals who plan to use larvicides or adulticides to control mosquitoes. This permit does not apply to homeowner use of insecticides for residential control of mosquitoes.

The application of mosquito larvicides or adulticides to Waters of the State requires permit coverage, whether it is a direct or indirect discharge. For example, a direct discharge is the application of larvicides directly to surface water, while an indirect discharge is the settling of adulticides onto a surface water even though the water was not the target area.
