West Nile Virus Detection
Oct 15, 2025 08:49AM ● By Solano County Mosquito Abatement District Press Release
DIXON, CA (MPG) - On Oct. 8, the Solano County Mosquito Abatement District (SCMAD) detected West Nile virus in mosquitoes off Tremont Road, Robben Road and near Bristol Way and Kingston Court in Dixon.
Residents in the affected areas are advised to take necessary precautions to avoid mosquito bites, especially if planning to spend time outdoors in and around the detection area. Recommended measures include using EPA-registered repellents containing DEET, Picaridin, Oil of Lemon Eucalyptus or IR3535, and wearing long-sleeved shirts and pants during peak mosquito activity hours.
Solano County Mosquito Abatement District technicians are conducting targeted control efforts in the affected area to reduce the mosquito population. These areas will continue to be monitored.
West Nile virus is primarily spread through mosquito bites. A mosquito becomes infected after biting a bird carrying the virus and can then transmit it to humans through subsequent bites.
Most people infected with West Nile virus do not show any symptoms. However, some individuals might experience fever, headaches or body aches. In more severe cases, the virus can lead to hospitalization or, in rare instances, death. Anyone experiencing symptoms is urged to contact their healthcare provider.
Certain groups are at higher risk for serious illness from West Nile virus. Older adults and individuals with chronic health conditions, including diabetes, high blood pressure, cancer or kidney disease, are more vulnerable to complications.

Preventing West Nile virus starts with mosquito control. Residents are encouraged to eliminate standing water around their homes by emptying flowerpots, buckets, pet dishes and old tires. Bird baths and pet bowls should be cleaned weekly and over-watering of lawns and gardens should be avoided.
Fixing leaks is also important. Broken sprinkler heads and leaky faucets should be repaired promptly to prevent water buildup.
To secure your home, inspect window and door screens for holes and ensure they fit properly. For those with pools or ponds, regular maintenance is essential. Pools should be kept clean and water circulating. Free mosquito fish are available for neglected pools, ponds, or water troughs to help control mosquito breeding.
