Areas of western Placer County are scheduled for treatment. An EPA-registered mosquito adulticide will be applied in an ultra-low volume fog by aircraft in an effort to address high mosquito numbers and West Nile virus activity.

Depending on wind speed and direction, the aircraft may not be traveling directly over the application area. The material will be applied in such a way that any wind will deliver the material into the target area.
Please note: Since several factors like weather conditions affect treatment activities, the District encourages Placer residents to check our website regularly for any changes to the treatment schedule.
