Aerial spraying again Saturday

-A +A
Two 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 Saturday evening, officials said. The samples were found in fields west of Roseville to Locust Road, north of Baseline Road to Sunset Boulevars 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 it’s not unusual for positive samples to turn up in agricultural areas at this point in the season. “We are responding as we normally would when addressing mosquito issues in this part of the country,” he said. 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 five mosquito samples that tested positive for the West Nile Virus. ~ Staff report ---------- How to combat mosquitoes: Drain any standing water that may produce mosquitoes.
