Mosquito Control Program
The Seminole County Mosquito Control Program is a section of the Watershed Management Division out of the Environmental Services Department.
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.
AERIAL SPRAYING
After Hurricane Milton, standing water left by flooding has caused a significant increase in mosquito breeding. With over 800 mosquito service requests currently in the system for Seminole County Mosquito Control, aerial spraying is a critical step in reducing high mosquito populations and protecting public health. Aerial spraying quickly and safely reduces the number of adult mosquitoes in large geographic areas, when conducted according to regulation. The risk of a mosquito-borne disease outbreak is greatly decreased when mosquito populations are reduced.
The State of Florida, under the Mosquito Control Incident Response Team (MCIRT), which is a specialized unit within the Florida State Agricultural Response Team (SART), will conduct aerial spraying over the highlighted areas on Wednesday, October 30. Spraying will take place from dusk to dawn. Completing the aerial mission is dependent on weather and other existing spray missions in queue.
There will be no spraying on Halloween, Thursday, October 31.
UPDATE: All aerial spray missions were completed for Seminole County on Wednesday, October 30. There will be no further spraying on Friday, November 1.
