The Placer Mosquito and Vector Control District announced today that the adult mosquito fogging scheduled for Wednesday 9/30/09 has been cancelled due to cool temperatures and expected windy conditions.
Adult mosquito populations have increased in some areas of Placer County over the past several weeks. While West Nile Virus activity seems to be slowing, recent high temperatures and adult mosquito abundance, continue to present a risk to public health.
Adult mosquitoes from three areas of western Placer County, Sheridan, Critter Creek Rd., and the area near Locust Road at Baseline Road, have tested positive for West Nile Virus.
Ten new West Nile Virus positive mosquito samples were reported today across western Placer County. Areas most affected are: North Lincoln, Sheridan, Western Roseville along Dry Creek, and the agricultural areas along the Placer-Sutter County border.
