Mosquito Control Program


In response to increasing mosquito populations in the aftermath of Hurricane Matthew and the attendant risk of mosquito borne viruses, Seminole County will begin aerial mosquito treatments at approximately 8:00pm on Friday, October 28, 2016, weather permitting. The areas to be treated are shown on the below map and comprise portions of eastern Seminole County, including in and around Lake Harney, Chuluota, Geneva, and Black Hammock. 

Gloria Eby, Director of the Seminole County Mosquito Control Program advised that for multiple weeks, Seminole County has been engaged in extensive larviciding and adulticiding (fogging) operations, stating that “As a result of Hurricane Matthew, many areas of the county are faced with extremely high numbers of mosquitoes that cannot be fully contained by our ground operations.”


The product used in this application, DUET, is registered for use with the U.S. EPA for mosquito population control, and it reportedly poses no undue risks to humans or the environment. According to the manufacturer, residents do not need to take any special precautions during the treatment.


Aerial applications provide a greater opportunity to reduce populations in hard-to-reach areas and have been shown to effectively disrupt the mosquito breeding cycle. Aerial applications have been used throughout the country to stem mosquito borne diseases, and are highly effective in reducing floodwater mosquito populations. 

DUET is applied at low dosage rates (1 oz/acre) using specialized equipment that automatically adjusts for aircraft speed, altitude, and wind velocity.
