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 cannot apply pesticides without justification.
Areas to be treated are highlighted in yellow. If no zones are highlighted there are no planned missions. The map is updated by noon each day.
All missions are subject to change due to weather.
