An insect elimination device has an outer grid with an inner grid disposed within the outer grid. A voltage source powers the inner grid, the outer grid or both. A warming tube is disposed within the inner grid and provides a thermal lure. A UV light source is disposed within the warming tube to provide a first optical lure. A control circuit controls the duty cycle, which is greater than 0% and less than 100%, of the UV light source while the voltage source is powering the elimination zone of the inner grid and the outer grid to keep the thermal lure within a predetermined temperature range. |
