US Patent 7181885 Insect trapping apparatus

An insect trapping apparatus and associated method attracts insects, such as mosquitos, by emitting a carbon dioxide gas as an insect attractant and producing a heat signature from the insect trap characteristic of a warm blooded animal and a blue light of a wavelength that attracts insects into the insect trap. The carbon dioxide gas is exhausted together with moisture through a vertically extending exhaust tube to minimize cooling of the carbon dioxide gas and minimize condensation of moisture while attracting insects through an inflow channel of an insect trap to trap the insects therein.
