West Nile spraying Friday evening

-A +A
Seven more mosquito samples tested positive for West Nile virus in Placer County this week, which means that another aerial spraying is due for the area this evening, officials said. The samples were found in fields west of Roseville to Locust Road, north of Baseline Road to Sunset Boulevard West and in a narrow corridor of fields in Sheridan, north of Wise Road, between North Dowd and Placer Roads. The area is a rice-growing region in western Placer County. General manager of the Placer Mosquito and Vector control district Joel Buettner said because of the increased number of infected samples, the areas are now considered “hotspots.” “These samples have only come from two sites,” he said. “Which means these areas are hotspots for West Nile virus activity. Typical district strategies employed in agricultural areas are to control mosquito larvae populations on a regular basis and implement adult mosquito control measures as needed. The area where the most recent positive samples were found will be sprayed and the district will also conduct mosquito larva control in the same area. This year in Placer County officials have found one bird and 12 mosquito samples that tested positive for the West Nile Virus. ~ Staff report ---------- How to combat mosquitoes: Drain any standing water that may produce mosquitoes.
