What pest is primarily targeted by CO2 light traps?

The primary target of CO2 light traps is mosquitoes. These traps use carbon dioxide as a key attractant, which is a major cue that mosquitoes use to find their hosts. When humans or animals breathe out, they release CO2, and certain mosquito species are particularly drawn to this gas, which helps the traps effectively capture them. The use of light in conjunction with CO2 enhances the attractivity, as many mosquito species are also attracted to light sources.

While biting flies may also be attracted to carbon dioxide, they do not respond to light in the same way that mosquitoes do, making these traps less effective for them. Bees are not attracted to CO2 or light in the same manner and are more focused on flowers and nectar sources. General flies may be attracted to some extent, but they are not the primary target of CO2 light traps, which are specifically designed for the capture of mosquitoes. This specificity is crucial for effective mosquito control strategies, particularly in areas where these pests are prevalent.
