How does a mosquito trap work?
Since the emergence of West Nile Virus (WNV) in North America in the 1990’s, mosquito traps are becoming increasingly popular in backyards across the U.S. and Canada. Most mosquito traps utilize a combination of carbon dioxide (CO2), heat, light, and chemical attractants to lure biting female mosquitoes to a suction device (vacuum) or glue board which then traps and kills the mosquito. As more and more female mosquitoes are trapped, the breeding pool is essentially reduced. Over time, the population in the area around the trap will collapse. This may take several weeks after the installation of a mosquito trap.
