A bug zapper, extra formally referred to as an electrical discharge insect control system, electric insect killer or (insect) electrocutor lure, is a machine that attracts and kills flying insects which might be attracted by light. A mild supply attracts insects to an electrical grid, where they're electrocuted by touching two wires with a high voltage between them. The identify comes from the characteristic onomatopoeic "Zap Zone Defender" sound produced when an insect is electrocuted. How Does a Bug Zapper Work? Inside Poundland's electric fly zapper bat. Do bug zappers really work? Bug zappers are normally housed in a protective cage of plastic or grounded metallic bars to forestall people or bigger animals from touching the high voltage grid. A mild supply is fitted inside, typically a fluorescent lamp designed to emit each seen and ultraviolet mild, which is seen to insects and attracts a wide range of them. Newer fashions now use lengthy-life LEDs to supply the light. The sunshine source is surrounded by a pair of interleaved bare wire grids or helices.

The distance between adjacent wires is typically about 2 mm (0.079 in). A high-voltage energy supply powered by wall power is used, which could also be a simple transformerless voltage multiplier circuit made with diodes and capacitors which might generate a voltage of two kilovolts or more. This is excessive sufficient to conduct by means of the physique of an insect which bridges the 2 grids, but not high enough to spark throughout the air hole. Enough electric current flows via the small physique of the insect to heat it to a high temperature. The impedance of the ability provide and the association of the grid is such that it cannot drive a dangerous current by the body of a human. Many bug zappers are fitted with trays that acquire the electrocuted insects; other models are designed to allow the debris to fall to the bottom below. Some use a fan to assist to entice the insect.
