Due to weather conditions, the Florida Keys Mosquito Control District could not conduct planned spraying missions Tuesday.
The agency rescheduled the spraying for today, weather permitting.
Aerial spraying from 6:30-8:30 a.m. will take place in the Upper Keys.
Airplanes will treat Middle Key Largo and Upper Key Largo from Mile Marker 98 to 107.
They will spread an adulticide applied at 0.75 ounces per acre, whose active ingredient is naled, which the district has used for almost 30 years.
