The Florida Keys Mosquito Control District will conduct aerial spraying from 6:30 to 8:30 a.m. this morning over Key Largo, Ocean Reef, and the Lower Keys, weather permitting. It will be rescheduled to Sunday if canceled.

Airplanes will treat Mile Markers 98 to 107. Helicopters will treat Geiger Key and the Saddlebunch Keys, from about Mile Marker 10.5 to 15.

They will spread Dibrom, an adulticide applied at 0.75 ounces per acre, whose active ingredient is naled, which the district has used for almost 30 years.
