New Jersey Light Traps

These are stationary traps that are strategically placed in 16 locations in the district from early April through October.  They capture mosquitoes and other insects by attracting them with light and then sucking them into a jar with a fan.  They are collected once a week and the mosquitoes are identified and counted to track population density in those areas.  Since these mosquitoes are dead when picked up they cannot be used for virus detection.
