Mosquito Surveys
Larval Surveys
Vector Control technicians locate, evaluate, map, and monitor hundreds of mosquito breeding sites countywide. Every breeding source is coded, based on habitat characteristics, and identified with grid numbers on the county map. This provides an overview of mosquito species and their locations, densities, and flight ranges. Larval surveys also furnish information on the effectiveness of control operations.

Adult Mosquito Surveys
The number and abundance of mosquito species is estimated by surveys of the mosquito adult population. This is accomplished by collecting mosquitoes at strategically located sampling stations throughout the county using CDC light and oviposition traps designed to attract and capture adult mosquitoes. Also, pooled mosquitoes are shipped to the Tennessee Department of Health laboratory for arbovirus identification.
