All spraying operations are conducted between 10 PM and 6 AM.
Spray missions are conducted based on trap counts and landing rates that are collected to assess the situation on a daily basis throughout the District. This is a required strategy as we can not apply pesticides without justification.
Areas to be treated are hi-lighted in yellow. If no zones are hi-lighted there are no planned missions. The map is updated by noon each day.
*County-wide Aerial Adulticiding is rescheduled for 9/22/2017 from the hours of 8 PM to 5 AM.
