The risk of contracting West Nile Virus may become significant again in Yuba and Sutter Counties this season. As a result the District plans to aggressively combat mosquitoes that carry the virus. By reducing the numbers of mosquitoes, the chances of a mosquito bite will diminish. More importantly, when disease is present, the chances for transmission are lowered. Fogging is performed during a temperature inversion. In the summer months, temperature inversions typically occur around dawn and dusk. Weekly fogging will begin before dawn.
The District takes advantage of the local newspapers, social media, radio stations and the internet to make residents aware of when spray operations will begin. Fogging routes will begin as early as 3:45 AM and may continue until 6:15 AM on Thursday mornings in Olivehurst, Linda, Arboga, Plumas Lake, Wheatland, East Marysville, Live Oak, Tierra Buena, Yuba City (Hillcrest area) and Sutter. Meridian and Robbins will be fogged on Tuesday or Wednesday evenings. Additional town areas and nights may be added if mosquito-borne disease activity becomes elevated. Interested persons can keep informed of spray operations by signing up for the District's spray notification email service and by visiting the District website or Facebook page throughout the mosquito season. Although the materials used by the District are labeled and registered for use in recreational and residential areas, sensitive persons are encouraged to avoid sprays by staying indoors, turning off evaporative coolers and by keeping doors and windows closed during these hours. This program begins as trapping data indicates a rise in our mosquito population but typically starts in late June and continues through July, August and September. During this time, residents that live in a town area that is fogged will be ineligible for individual service at their homes. We would be happy to answer any questions you may have about this program. Please contact our office Monday thru Friday between the hours of 7 AM and 3:30 PM.
