Mosquito Control Program


Information about the "Gallinipper" mosquito:

Although various media outlets have suggested that these mosquitoes are new and "invading Seminole County", this is simply not true.  This mosquito, Psorophora ciliata, has been found all over the eastern United States including all parts of Florida.  Seminole County Mosquito Control works year round to pre-treat areas associated with this mosquito and other species by applying material that can last from 30-180 days. 

The map below shows it's range:
Range of Psorophora ciliata

A full description of the mosquito and it's habitat can be found here.

Some information of special note:  This mosquito is not known to transmit any mosquito borne diseases and is typically found in rural areas.  Central Florida is home to between 30 and 40 species of mosquito.  Controlling disease-carrying mosquitoes is our primary duty.


The Seminole County Mosquito Control Program is a section of the Watershed Management out of the Public Works Department.

Mission Statement

Our mission is to provide environmentally safe, effective and economically responsible mosquito control for the residents of Seminole County. Seminole County Mosquito Control promotes cooperation and communication with property owners, residents, and other government agencies to help in these efforts.

Seminole County Mosquito Control conducts routine inspections and treats areas as needed based on weekly routes, as depicted in this map. All adult mosquito control measures are conducted after justified in accordance Florida Administrative Code 5E-13.036.
