Risk of West Nile virus is becoming elevated throughout Sutter County, as a second sample of mosquitoes has tested positive for the mosquito-borne virus. “We’re beginning to see virus activity in our surveillance system that is becoming widespread making the risk for human infection elevated,” said Stephen Abshier, District Manager. “If you’re going to be outside anywhere in Yuba and Sutter Counties when mosquitoes are active, please don’t take any chances and protect yourself by applying a good mosquito repellent and by wearing long sleeves and pants at dawn and dusk when mosquito activity is high. This will go a long way in preventing mosquito bites,” added Abshier. In response to recent findings and increased virus activity, District staff will continue to aggressively target adult and larval stages of mosquitoes. The District continues to treat urban areas with high WNV activity with truck mounted foggers on Thursday evenings to reduce the adult mosquito population. As a result of the two, mosquito sample, virus detections, we have added twice weekly spraying in Live Oak and also the Shanghai Bend area of Yuba City with the addition of treatments on Monday evenings. Agricultural areas west of Yuba City, north of Marysville, south of Olivehurst and east of Plumas Lake continue to be treated by aircraft for adult mosquitoes with spray missions occurring after dusk on any day of the week. These spray areas can be viewed at the District’s website at Individuals can also sign up for email notification of mosquito spraying at the District’s website or follow us on Facebook.
