Aerial Spraying

You can get general information on aerial spraying for mosquito control to help answer some of your questions.  Learn about the effectiveness of aerial spraying, insecticides used and more.   

2017 Mosquito Season

Miami-Dade County completed aerial spraying for mosquitoes on Friday, June 16. 

Canceled Spray Missions:  The aerial spray mission scheduled for May 16 and June 15 were canceled due to poor weather conditions.

2016 Mosquito Season 

Miami-Dade County used aerial spraying during the 2016 mosquito season to help control the mosquito population in Miami Beach and the Wynwood area north of downtown Miami. These areas were identified by the Florida Department of Health as areas with confirmed cases of locally transmitted Zika. Wynwood and Miami Beach are no longer considered areas of active transmission. 

Truck Spraying

The County performs truck spray treatments to eliminate mosquito larvae and adult mosquitoes. Larvicide treatments are conducted using Buffalo Turbine equipment to apply the organic pesticide BTI to eliminate mosquitoes at the larval stage. When necessary, Mosquito Control crews perform adulticide treatments by truck to eliminate adult mosquitoes. Equipment used in both applications is mounted on pickup trucks.

A fine mist of the pesticide product is applied as the trucks move along the street. When operated, the spray equipment emits a sound similar to the buzz of a lawn mower. Larvicide truck treatments are typically performed overnight in the pre-dawn hours. Adulticide treatments are performed at dawn or dusk when adult mosquitoes are most active. Every effort is made to avoid use of the pesticide product when residents are active.
