The Sutter-Yuba Mosquito and Vector Control District has detected the first evidence of West Nile virus (WNV) in Yuba County in 2024. One mosquito sample collected on Tuesday, June 25th in the east Marysville area has tested positive for West Nile. Thus far, we have had no detections of WNV in dead birds, sentinel chicken flocks or humans in 2024. Hot daytime temperatures are hastening mosquito production, with traps showing an increase of this WNV vector for this time of year. The District’s surveillance system continues to be in full operation and mosquito control efforts are being instituted in areas where detections are made.

The Sutter-Yuba Mosquito and Vector Control District would like to remind the public that prevention of mosquito bites is the best way to protect against West Nile virus and other mosquito-borne viruses at home and when traveling.  Taking simple steps to prevent mosquito bites are the best ways to keep you and your family healthy. Remembering the 4 “D”s is an easy way to help prevent mosquito bites:

D – DEET – apply mosquito repellants containing DEET, picaridin, oil of lemon eucalyptus or IR3535 when mosquitoes are active or biting.  These are the EPA approved mosquito repellents recommended to prevent bites ( Always follow package instructions for appropriate age and directions for use.

D – Dawn and Dusk – limit outdoor activity at dawn and dusk when the mosquitoes that carry WNV are most active. Wear long sleeves and pants if you must be outdoors when mosquitoes are present.

D – Doors and windows – keep screens in good repair and keep mosquitoes out, by making sure that the screens on your doors and windows are not broken or torn.

D – Drain all standing water around the outside of your home – buckets, jar lids, tires and flower pot trays are some common places. Report green swimming pools to the District.

Residents are asked to report dead birds to the California Department of Public Health website at or by phone at 877-968-2473.
