Abstract: An insect trap including a suction device to suck insects into a catch where they are killed or detained. The insect trap also includes a catalytic reactor that uses a portion of the air and a combustible fuel to produce CO2. The CO2 is expelled from the trap at one end and the intake air is sucked in at the other. Intake and outlet ports for the intake air and lure respectively are angled toward each other. Accordingly, more insects that are drawn to the lure become trapped in the intake air.
