A bug zapper, Zap Zone Defender Setup extra formally referred to as an electrical discharge insect management system, electric insect killer or (insect) electrocutor entice, is a system that attracts and kills flying insects which can be attracted by light. A light source attracts insects to an electrical grid, where they are electrocuted by touching two wires with a excessive voltage between them. The identify comes from the characteristic onomatopoeic "Zap Zone Defender Setup" 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 protecting cage of plastic or grounded metal bars to forestall individuals or bigger animals from touching the excessive voltage grid. A gentle source is fitted inside, typically a fluorescent lamp designed to emit both visible and ultraviolet light, which is seen to insects and attracts a wide range of them. Newer models now use lengthy-life LEDs to supply the light. The light supply is surrounded by a pair of interleaved naked wire grids or helices.

The space between adjacent wires is often about 2 mm (0.079 in). A excessive-voltage energy supply powered by wall power 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 extra. That is high enough to conduct via the physique of an insect which bridges the two grids, Zap Zone Defender Setup but not high sufficient to spark across the air hole. Enough electric present flows by means of the small physique of the insect to heat it to a high temperature. The impedance of the ability supply and the arrangement of the grid is such that it cannot drive a dangerous current by the physique of a human. Many bug zappers are fitted with trays that collect the electrocuted insects
