Center for Disease Control Mosquito Trapping

CDC (Center for Disease Control) Light traps are used to collect and monitor adult mosquitoes.

Traps are set in the late afternoon and run throughout the night. The traps are collected and picked up the next day to be examined and identified at the BLSG facility.

When each trap is set out it is filled with dry-ice. As the dry ice breaks down it omits CO2, a primary attractant to female mosquitoes.  The female mosquitoes sense the CO2 and are drawn to the trap and the trap’s fan blades force them into the catch bag which is collected for identification and disease testing.

If you see a trap please do not disturb.
