The Florida Keys Mosquito Control District will conduct aerial spraying from 6:30 to 8:30 this morning over the Upper Keys as well as Cudjoe Key, weather permitting.

Airplanes will treat Middle and Upper Key Largo, and Ocean Reef, Mile Markers 98 to 107, as well as Upper Matecumbe, Windley and Plantation keys, and Lower Key Largo, Mile Markers 80 to 98.

Helicopters will treat Cudjoe Key.

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.
