(US6145243-A)   NOVELTY - The apparatus includes an insect trap with an inlet for entering of insects. A gas source is capable of providing gas having a temperature above ambient temperature. An attractant exhaust system coupled is to the CO2 gas source. The attractant exhaust system cools heated CO2 gas and releases an insect attractant that consists of the cooled CO2 gas near the trap inlet at a temperature above ambient temperature and below approximately 115oF.    USE - The invention relates to methods and apparatus for attracting and trapping or otherwise disabling insects, and, in particular, to a counter flow device that introduces CO2, gas and then cools the CO2 gas for use as an insect attractant in an outflow from the trap.    ADVANTAGE - Allows the apparatus to be easily transported to a selected position out of doors while it may generate all the electrical power it needs to operate continuously and virtually unattended for an entire month on a single, standard 20-pound tank of liquid propane fuel.
