CANCELED: Aerial Adulticide Treatment In Western Placer Tonight, August 19, 7:30-11 P.M.

*Due to wildfire smoke and unpredictable wind conditions, we were unable to safely conduct the planned aerial adulticide treatment last night. We are shifting to ground-based treatments although ground-based treatments do not allow us to treat as many areas as aerial applications. 

We will continue mosquito and WNV surveillance activities and provide updates as they become available. Should the smoke and weather conditions change, we will reassess our aerial application options to do our best to protect public health in Placer County.

Planned Aerial Adulticide Treatment

What: Adult mosquito treatment
Where: Western Placer County
When: Tonight, August 19, 7:30 – 11 p.m.

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

Depending on wind speed and direction, if tonight’s application is able to move forward, the aircraft may not be travelling directly over the application area but will be applied in such a way that any wind will deliver the material into the target areas as seen in the map below. Areas of Lincoln, Roseville and south Placer County near the Sacramento County border, may see the plane flying overhead.

Areas of 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 tonight, August 19, 2020, between 7:30 and 11 p.m.

  • 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.

Tahoe Basin Plague Update

On August 17, 2020, our neighboring county reported that a resident in South Lake Tahoe tested positive for plague. We are encouraging visitors and residents of the Tahoe Basin area to be aware of the potential risk of rodent-borne disease and protect themselves.

What is plague?
Plague is a rare, yet highly infectious and potentially deadly disease. People may be exposed to plague through the bite of an infected flea, handling an infected rodent or exposure to an infected pet. It is also important to avoid dead rodents as infected fleas may be jumping off the dead animals and seeking new hosts nearby.

How to Protect Yourself from Plague
  • Avoid camping, sleeping or resting near rodent burrows.
  • Avoid contact with wild rodents like ground squirrels, chipmunks, woodrats, mice and marmots and their fleas.
  • Do not feed wild rodents in picnic or campground areas.
  • Do not handle sick or dead rodents.
  • Wear long pants tucked into boot tops to reduce exposure to fleas.
  • Apply insect repellent containing DEET on socks and trouser cuffs.
  • Keep wild rodents out of homes, trailers and outbuildings.
  • Report any sick or dead animals to forest, campground or local health officials.
  • For protection of pets, keep pets leashed and away from dead rodents. If a pet becomes sick after visiting a high-risk area, take the pet to a veterinary clinic and inform them that the pet has been in an area where rodents have plague.
Symptoms of Plague
Early symptoms of plague include high fever, chills, nausea, weakness and swollen lymph nodes in the neck, armpit or groin. Individuals who develop these symptoms within two weeks of possible exposure should seek immediate medical attention. Plague is curable in its early stages but may be fatal if not treated early.
