SAN JOSÉ, CALIF. - Thursday, February 14, 2013. The Santa Clara County Vector Control District (SCCVCD) reports that the operations to control for the breeding of Salt Marsh Mosquitoes in the Alviso Marsh, Smith Yard Marsh, New Chicago Marsh, and Zanker Marsh were completed today at 12:00.

The aerial treatment was carried to minimize the number of "winter salt marsh mosquito” (Aedes squamiger) and reduce the risk of mosquito bites to residents in the surrounding communities. Post treatment samples will be collected to evaluate the effectiveness of this aerial larvicide treatment.

Aedes squamiger lays its eggs in the moist soil in late spring and early summer.  These eggs can lay dormant for many years, even after repeated flooding.  High tides and seasonal rains, together with the short days and cooler temperatures of winter, cause the eggs to hatch as early as November.  Although this species has not yet been shown to transmit West Nile Virus, it is known to bite viciously during the day and can fly over 20 miles from its breeding grounds to feed on humans and other mammals.
