Risk of West Nile virus continues to be high throughout Sutter and Yuba counties as more mosquitoes test positive for the virus. “We continue to see ongoing and high virus activity in our surveillance system that is widespread and the risk for human infection is elevated,” said Michael Kimball, District Manager. “Residents need to remain vigilant in protecting themselves from being bitten by mosquitoes” added Kimball. “We want to remind everyone to stay protected by always wearing a good mosquito repellent and by wearing long sleeves and pants at dawn and dusk when mosquito activity is high” Kimball emphasized. 
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. We have added twice weekly spraying in east Marysville, Sutter and Olivehurst with the addition of treatments on Monday evenings. Monday evening fogging routes have been added to NW Yuba City as well as SE Yuba City south of Lincoln Road. Agricultural areas west of Yuba City, north of Marysville, south of Olivehurst and east of Plumas Lake will be treated by aircraft for adult mosquitoes when necessary 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. A surveillance map can be found there as well which shows the location of WNV positive dead birds, mosquito collections and sentinel chickens.
