Florida Department of Agriculture and Consumer Services to Begin Aerial Mosquito Treatments
Seminole County Will Receive Aerial Treatment This Week

 SEMINOLE COUNTY, FL, (September 25, 2017) – In response to increasing mosquito populations as a result of Hurricane Irma, resident complaints, and the risk of mosquito borne viruses, at the request of Seminole County, Florida Department of Agriculture and Consumer Services (FDACS) will conduct aerial mosquito treatments at approximately 9:00 p.m. on Thursday, September 28, weather permitting.  Approximately 49,000 acres in the eastern rural areas of Seminole County, including Lake Jesup, Lake Harney, Geneva, Chuluota, and Black Hammock, will be treated. Federal funding will assist Seminole County with associated costs of the aerial mosquito treatment, as the County has been declared a federal disaster area following Hurricane Irma. In the event weather prohibits aerial treatment on the originally scheduled date of September 28, an alternative date of Friday, September 29 at 9:00 p.m. has been arranged.

“Seminole County continues to conduct extensive larviciding and adulticiding operations from the ground,” said Gloria Eby, Director of Seminole County Mosquito Control Program.  “In the aftermath of Hurricane Irma, 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 curb mosquito-borne disease, such as West Nile Virus outbreaks, and are highly effective in reducing floodwater mosquito populations.

Aerial treatment efforts strategically occur during the evening and do not include the application of materials known to be harmful to humans, animals or other insects, including bees when applied according to the label. The product used, naled, is registered with the U.S. EPA for use in mosquito population control.  The Center for Disease Control has created a website specific to aerial treatment that includes frequently asked questions.

Residents are not required to take additional precautions to safeguard livestock, pets or gardens. The decision to conduct aerial treatment follows other Central Florida counties implementing aerial spraying.

As a service to the local beekeeper community, Seminole County Mosquito Control remains in close contact with the Seminole County Beekeepers Association to ensure bees are not subject to the treatments.
