Ground-based Adult Mosquito Treatment in Sheridan and Roseville 8/6/2013 3:30-6:00 AM

Areas of Sheridan and Roseville are scheduled for treatment for significant mosquito and West Nile virus activity.  An EPA-approved mosquito adulticide will be applied in an Ultra Low Volume (ULV) fog by truck to target adult mosquitoes.

Treatment areas:

  • Sheridan – Residential areas east of Hwy. 65, from Rolling Hills Rd, south to the Sheridan Cemetery. See map here.
  • Roseville –  Residential areas from Hayden Parkway south and west of Fiddyment Road to city border including some unincorporated areas west of the city. See map here.

Since several factors affect treatment activities, such as weather and wind conditions, the District encourages Placer residents to check the District website regularly for any changes to the treatment schedule.
