Trapping and Disease Surveillance

Sarasota County has several dozen carbon dioxide bated traps placed throughout the area which serve as a method for population surveillance. During mosquito season, May 1 until Oct. 31, these traps are collected several times per week and adult mosquitoes are counted.

For disease surveillance, Mosquito Management Services uses specialized traps to attract blood fed female mosquitoes. Sentinel chicken populations are also monitored year-round.


Spray Criteria

Treatments (spray missions) are scheduled only on an as-needed basis. The type of treatment, whether it be ground or aerial, is based upon what zones are being selected. 

Several components contribute to missions which include adult population data, disease surveillance data, and service requests. If you have an issue with mosquitoes in your area, submit a Service Request today!
