Seminole County to Begin Aerial Mosquito Treatments, 9:00 p.m. on Wednesday, August 9

SEMINOLE COUNTY, FL, (August 3, 2017) – In response to recent heavy rainfall, increasing mosquito populations, and the risk of mosquito borne viruses, Seminole County will begin an aerial mosquito treatment beginning at approximately 9:00 p.m. on Wednesday August 9th, 2017, weather permitting.  The area to be treated totals 22,000 acres in the rural eastern part of the County, including in and around Lake Harney, Geneva, and Black Hammock.

“Seminole County has been conducting extensive larviciding and adulticiding operations from the ground,” Gloria Eby, Director of Seminole County Mosquito Control Program.  “With the increased rains following extended drought conditions, many areas of the county are faced with extremely high numbers of mosquitoes that cannot be fully contained by our ground operations using trucks.”


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 disease such as West Nile Virus outbreaks, and are highly effective in reducing floodwater mosquito populations.


The product used in this application, DUET, is registered for use with the U.S. EPA for use in mosquito population control and poses no undue risks to humans or the environment. Residents do not need to take any special precautions during the treatment. DUET is the same product that was used by Seminole County for aerial services last year.

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