Due to recent rainfalls, the Mosquito Control district will continue aerial larviciding missions over the western portion of Key West from 6:30 to 9:30 a.m. Thursday, weather permitting.
A helicopter will be spraying Bti, which is a mosquito larva-specific bacteria, mixed with water and applied as a mist to combat Aedes aegypti, the mosquito that can transmit dengue fever. Though dengue has not been confirmed in the area since 2010, the district is conducting the sprays to reduce the overall mosquito population.
All applications are subject to change should high winds and/or rainfall cause a need for cancellation. The district would then reschedule another date to spray.
