Anti-Mosquito Spraying
NUEVO (CNS) – For the second time in roughly two weeks, Riverside County vector control officials will conduct anti-mosquito spraying in Nuevo, covering a total 253 acres, to eradicate growing infestations that pose a potential risk to public health.
The Department of Environmental Health scheduled “ultra-low volume” insecticide spraying between 4 a.m. and 7 a.m. Thursday in the following three locations:
— Mystic Field, specifically the area bounded by Lakeview Avenue to the south, Reservoir Avenue to the north, Orange Avenue to the east and Magnolia Avenue to the west;
— East Nuevo, bounded by Reservoir to the north, Lakeview to the south, Fifth Street to the east and Sixth Street to the west;
— and the largest space, covering 172 acres, encompassing portions of west Nuevo, specifically Ninth Street to the north, 10th Street to the south, Reservoir to the west and Yucca Avenue to the east.
This week’s spraying will be the second time for the area since July 31, when the exact same spaces were targeted.
According to Department of Environmental Health Deputy Director Jenay Marcotte, concentrations of mosquitoes in the area that tested positive for West Nile virus have raised ongoing concerns about the potential for transmission.
Anti-mosquito spraying involves the use of chemicals approved by the U.S. Environmental Protection Agency. Pesticides are emitted as a mist dispersed from machines anchored in the backs of pickup trucks. Marcotte recommended that during operations, residents stay indoors and keep windows closed until at least 15 minutes after the trucks have departed.
Two human WNV infections have been documented in Riverside County so far this year. Additionally, statewide, seven infections have been recorded to date in 2024, according to the California Department of Public Health. One of those, in Northern California, resulted in a fatal outcome.
In 2023, 21 human WNV infections were documented in Riverside County, none of which resulted in fatalities. No cases were documented in 2022, according to the county Emergency Management Department.
Mosquitoes typically become carriers of the virus after feeding on an infected bird and can then spread the potentially lethal strain to animals and humans. Those at greatest risk include seniors and individuals with compromised immune systems.
Symptoms may never materialize, but can include fever, headache, nausea, body aches, skin rashes and swollen lymph nodes.
Mosquito season in Southern California generally spans May to October. To reduce exposure to mosquitoes with WNV, residents are urged to:
— spend as little time as possible outdoors at dawn or dusk, when mosquitoes are generally on the move;
— wear long pants and long-sleeved shirts during outdoor activity in mosquito-prone areas;
— use insect repellent;
— ensure door and window screens are fitted properly to keep bugs out; and
— get rid of standing water, aside from pools properly treated with chemicals.
Anyone with concerns should contact the Department of Environmental Health at 951-766-9454.
