An apparatus is described that utilizes ultraviolet rays as an attrahent for winged insects. It is asserted that ultraviolet radiation is much more effective in attracting insects than the ordinary electric light. The apparatus consists essentially of a mercury vapor lamp of about 3,500 candle power mounted above a basin of water 1.1 meters in diameter. An aspirator driven by an electric motor connects with the base of the lamp and draws the stunned insects into a fabric bag. The basin of water traps those not drawn in by the aspirator. A high degree of efficiency in disposing of various moths, beetles, flies, ants, winged aphids and mosquitoes is claimed for the apparatus.
