Abstract
A method of trapping common houseflies and many other flying insects is disclosed. The method utilizes a device comprising an upright array of parallel exposed conductors dimensioned and spaced such that alighting houseflies virtually have to alight in contact with two such conductors, means to periodically apply opposing pulsating charges to adjacent pairs of such conductors which causes such houseflies to dive downwardly toward an adhesive-covered sheet or other means to receive and hold insects diving from the array. The charges are about 25 to 40 volts peak and have a frequency of about 60 to 600 Hz. Applying such charges as a square wave is very hightly preferred.
