Aerial Adulticide Treatment In Lincoln And Western Placer Tonight, August 26, 7:30-11 P.M

Planned Aerial Adulticide Treatment

What: Adult mosquito treatment
Where: Lincoln and Western Placer County
When: Tonight, August 26, 7:30 – 11 p.m.

PLEASE NOTE: Due to fires, wind and unstable weather conditions, tonight’s treatment may be rescheduled.

Areas of Lincoln and Western Placer County are scheduled for an aerial adulticide treatment tonight due to high adult mosquito counts and positive West Nile virus mosquitoes. An EPA-registered mosquito adulticide will be applied in an ultra-low volume fog by aircraft to target adult mosquitoes.

  • Residential and commercial areas of North Lincoln, north of Auburn Ravine west of Lincoln Blvd
  • Both sides of S Brewer Road north of E Catlett Road
  • Residential and rural areas west of Fiddyment Road in Roseville to the Placer/Sutter County line south of Sunset Blvd W and north of Baseline Rd.

Adult mosquito control treatments are made to prevent the transmission of West Nile virus to people. A number of factors including the aircraft, weather conditions and adult mosquito and disease surveillance information must be considered for a safe and effective application. Due to these factors, the District encourages Placer County residents to check the District website for any changes to the planned treatment schedule and accompanying treatment area maps.

Wind speed and direction is especially important during adult mosquito applications. The District only uses aerial mosquito control contractors who use specialized systems to allow the pilot to measure the wind and fly in a way to deliver the material into the target area. This means that sometimes the aircraft will need to fly upwind of the target area to compensate for the wind.

Increased West Nile Virus Risk in Placer County

The Placer Mosquito and Vector Control District’s mosquito and West Nile virus testing showed an increased risk of WNV transmission in the following areas of Placer County:

1. All rural areas in western Placer County
2. Western Lincoln west of Lincoln Blvd.
3. Western Roseville west of Fiddyment Rd.
4. Northern Rocklin especially along Pleasant Grove Creek

Residents in these areas are advised to stay inside during dusk and early evening hours and wear protective clothing and an EPA registered repellent if you have to be outside.

The District will be conducting mosquito control treatments in these areas to reduce the amount of WNV infected adult mosquitoes.
