North Fork Area Mosquito Trap Data
<-----To view this page best, click on "Toggle Menu Display"
We currently have 33 trap locations throughout our District. They are set one night per week and collect adult mosquitoes for 12 hours. By emiting light and carbon dioxide, the traps attract mosquitoes in the same way humans do. The number of mosquitoes in a particular trap on a given night is about equal to the "landing count" a human could expect in that area over the same twelve-hour period.

The adult mosquitoes that are captured in our light traps are frozen and identified to species. Species numbers are tallied and monitored weekly for peaks and dips in the trap population. A trap that suddenly has a high number of mosquitoes indicates there is a water source near that is breeding mosquitoes. Since each species of mosquito has breeding site preferences, our search is focused.

The same week high trap counts are detected, our crew is on foot in that area, trying to find the water and source of the mosquitoes. Our efforts in locating mosquito breeding sites, when successful, have resounded in the following week's trap counts. If, on the other hand, the trap numbers show no decline, we are back combing the area again.
