A flying insect trapping device configured to be used with a fuel supply containing a combustible fuel, the trapping device comprising: a supporting frame; and, an insect inlet configured to receive flying insects; and, an insect trap chamber communicated to the insect inlet, and configured to receive the flying insects from the insect inlet; and, a combustion device configured to provide an interior space for continuous combustion of the combustible fuel therein to create an exhaust gas comprising carbon dioxide; a plurality of heat exchanger elements extending inwardly into the interior space of the combustion device for conducting heat generated by the continuous combustion; an exhaust outlet configured to receive the exhaust gas and allow the exhaust gas to flow outwardly therethrough so that insects attracted to the carbon dioxide in the exhaust gas will fly towards the trapping device; and, an electrically powered vacuum device communicated to the insect inlet and constructed to draw the insects attracted to the trapping device into the insect trap chamber via the insect inlet; and, a heat sink configured to dissipate heat; and a thermoelectric device for generating electric current as heat transfers from a first side thereof to a second side thereof, the thermoelectric device having the first side disposed in contact with the combustion device and the second side disposed in contact with the heat sink to enable heat generated by the continuous combustion, including heat conducted by the heat exchanger elements, to be transferred to the heat sink via the thermoelectric device to generate the electric current, the thermoelectric device being electrically coupled to at least the vacuum device to power the vacuum device; the interior space is a hollow interior space; the combustion device includes a turbulence reducing structure for substantially laminating flow of a mixture of the combustible fuel and air, and a catalyst element disposed downstream of the turbulence reducing structure; the combustion device includes a heat zone; characterised in that the combustion device includes a laminating zone upstream from the heat zone and a catalyst zone downstream of said heat zone; and the heat exchanger elements include a plurality of heat exchanger fins in the heat zone, said heat exchanger fins extending radially inwardly into the interior space of the combustion device, said heat exchanger fins conducting heat away from the interior space of the heat zone while minimizing disruption of the flow of exhaust gas flowing through the combustion chamber. a supporting frame;
