The recent heavy rain has created instant ponds and lakes, such as the ones covering the Sawgrass Mills parking lots, magnetize mosquitoes. To combat that, Broward County will be spraying Thursday night and Friday night to kill the larvae of Zika-carrying mosquito Aedes Aegypti.
But they won’t be spraying Naled.
A University of Michigan study linked Naled, used in Florida for many years as a mosquito fighter, to motor dysfunction in Chinese babies. Broward County’s using Vectobac WDG, the active ingredient of which is Bacillus thuringiensis israelensis (Bti).
The county’s release describes BTi as “a naturally occurring, biodegradable bacterial mosquito larvicide which is not harmful to humans, pets, bees, aquatic habitats or environmentally sensitive areas. It is certified by the Organic Materials Review Institute (OMRI) and is registered for use by the US Environmental Protection Agency.”

Broward County Highway and Bridge Maintenance Division Director Anh Ton e-mailed the Miami Herald, “We have no plan to use Naled at this point.”
Ton said Thursday night’s spraying, which will be from 10 p.m. to 6 a.m. in parts of Hollywood, will be the second larvicide spraying of the season. The county sprayed around three schools for at-risk teens last week.
Thursday’s Hollywood spray zone is bordered by Sheridan Street/Southwest 16th Street on the north; Pembroke Road on the south; Interstate 95 on the west; and Dixie Highway on the east.
Friday’s spraying, also from 10 p.m. to 6 a.m., will cover Fort Lauderdale from I-95 on the west to Southwest Fourth Avenue on the east; and State Road 84/Marina Boulevard on the south to Southwest 12th Street/Davie Boulevard on the north.
Also, Friday night, spraying will occur in an area framed by University Drive on the west; Rock Island Drive on the east; Oakland Park Boulevard on the south; and Northwest 44th Street on the north.
Residents and business owners are reminded to eliminate as much standing water as possible to prevent mosquito growth.
