This mosquito is found in permanent waters, especially where you find plants emerging, like cattails. Their larvae will attach themselves to the plant stem, so using a larvacide in the water may not be very effective. They like to feed on darker days from dusk time on till around midnight. They overwinter in the larvae form in all instars. The females have a severe bite.
The best control for the adults is fogging a treatment into shrubs, wood lines, and hedgerows.
