A bug zapper, Zap Zone Defender more formally referred to as an electrical discharge insect control system, electric insect killer or (insect) electrocutor entice, is a machine that attracts and kills flying insects which can be attracted by mild. A gentle source attracts insects to an electrical grid, where they are electrocuted by touching two wires with a high voltage between them. The name 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 often housed in a protective cage of plastic or grounded metal bars to forestall individuals or larger animals from touching the excessive voltage grid. A mild supply is fitted inside, typically a fluorescent lamp designed to emit both seen and ultraviolet light, which is visible to insects and attracts a wide range of them. Newer fashions now use lengthy-life LEDs to provide the sunshine. The light supply is surrounded by a pair of interleaved bare wire grids or helices.

The space between adjacent wires is usually about 2 mm (0.079 in). A high-voltage power provide powered by wall energy is used, which could also be a easy transformerless voltage multiplier circuit made with diodes and capacitors which can generate a voltage of 2 kilovolts or more. That is excessive enough to conduct by the body 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 power supply and the arrangement of the grid is such that it cannot drive a harmful current by way of the physique of a human. Many bug zappers are fitted with trays that acquire the electrocuted insects
