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.
