A bug zapper, extra formally known as an electrical discharge insect control system, pest control device electric insect killer or (insect) electrocutor trap, is a device that attracts and kills flying insects which might be attracted by light. A mild source attracts insects to an electrical grid, the place they're electrocuted by touching two wires with a high voltage between them. The name comes from the characteristic onomatopoeic "zap" sound produced when an insect is electrocuted. How Does a Bug Zapper Work? Inside Poundland's electric bug zapper fly zapper bat. Do bug zappers really work? Bug zappers are usually housed in a protecting cage of plastic or grounded metallic bars to forestall folks or larger animals from touching the high voltage grid. A gentle source 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 source 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 high-voltage energy provide powered by wall power is used, which may be a easy transformerless voltage multiplier circuit made with diodes and capacitors which may generate a voltage of 2 kilovolts or extra. That is excessive sufficient to conduct by the body of an insect which bridges the 2 grids, but not excessive sufficient to spark across the air hole. Enough electric current 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 association of the grid is such that it can not drive a harmful current by the physique of a human. Many outdoor bug zapper zappers are fitted with trays that gather the electrocuted insects
