Aug. 18, 2021. Reno/Sparks, Nev. The Washoe County Health District (WCHD) – Vector Borne Disease Program (VBD) will be conducting aerial larviciding applications on Thursday, Aug. 19, 2021. Aerial treatment will begin in the North Valleys and end in the southern portion of Washoe County covering approximately 800 acres.
Aerial larviciding is done by helicopter and targets areas with dense mosquito larvae in the water or wetlands to hinder their ability to grow into full-sized biting adults. The main way West Nile virus is transmitted to humans is through mosquitoes. Aerial larviciding is environmentally friendly and done by dropping non-liquid granular products with the goal of maintaining safe recreational environments in Washoe County.
The main areas of focus will include the North Valleys, Swan Lake, South Meadows, Double Diamond, Damonte Ranch and Washoe Valley Areas.
Larviciding has no effects on pets or humans who are in those areas…
