A bug zapper, more formally referred to as an electrical discharge insect management system, electric insect killer or (insect) electrocutor trap, is a device that attracts and kills flying insects that are attracted by gentle. A gentle supply attracts insects to an electrical grid, the place they're electrocuted by touching two wires with a excessive voltage between them. The title 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 actually work? Bug zappers are normally housed in a protecting cage of plastic or grounded steel bars to prevent folks or bigger animals from touching the high voltage grid. A light source is fitted inside, typically a fluorescent lamp designed to emit each seen and ultraviolet light, which is seen to insects and attracts quite a lot of them. Newer models now use lengthy-life LEDs to supply the sunshine. The sunshine source is surrounded by a pair of interleaved bare wire grids or helices.

The gap between adjacent wires is typically about 2 mm (0.079 in). A excessive-voltage energy provide powered by wall energy is used, which could also be a easy transformerless voltage multiplier circuit made with diodes and capacitors which may generate a voltage of 2 kilovolts or extra. This is high sufficient to conduct through the body of an insect which bridges the two grids, Zap Zone Defender however not high enough to spark across the air gap. Enough electric present flows by the small body of the insect to heat it to a high temperature. The impedance of the power provide and Zap Zone Defender the arrangement of the grid is such that it can not drive a harmful present by way of the body of a human. Many bug zappers are fitted with trays that gather the electrocuted insects
