RENO, Nev. (News 4 & Fox 11) — The Washoe County Health District Vector-Borne Diseases Program will conduct its third seasonal helicopter larviciding application in the early morning hours of Wednesday, July 11.
The larviciding will cover the Silver Lake, Swan Lake, Lemmon Valley, Kiley Ranch, Red Hawk, Rosewood Lakes, Butler Ranch, South Meadows, Damonte Ranch, and Washoe Valley areas to prevent mosquito hatching over approximately 800 acres.
Health officials report the applications will consist of Vectolex, a biological larvicide that only targets mosquito larvae, with no affect to humans, fish, water fowl or other beneficial insects such as bees.
Halting the growth of biting mosquitos can also prevent the spread of arboviruses like West Nile Virus (WNV), a virus most commonly spread to people by mosquito bites.
In North America, cases of WNV occur during mosquito season, which starts in the summer and continues through fall.
WNV cases have been reported in all of the continental United States. There are no vaccines to prevent or medications to treat WNV. Fortunately, most people infected with WNV do not have symptoms. About 1 in 5 people who are infected develop a fever and other symptoms.
About 1 out of 150 infected people develop a serious, sometimes fatal, illness.
While monthly larviciding is expected to reduce the number of mosquitos in the area, health officials remind people that they also should take steps to avoid being bitten by mosquitos.
To avoid mosquito bites:
If you are experiencing biting mosquitos call the Vector-Borne Diseases Program at 785-4599, and staff will investigate the source of these adult mosquitos.
The Vector-Borne Diseases Program also has mosquito fish available for ponds, troughs and other impoundments containing water which will prevent mosquito larvae from hatching into biting adult mosquitos.
