A bug zapper, more formally referred to as an electrical discharge insect management system, electric insect mosquito killer or (insect) electrocutor lure, is a gadget that attracts and kills flying insects which can be attracted by light. A mild supply attracts insects to an electrical grid, the place they're electrocuted by touching two wires with a high voltage between them. The title comes from the characteristic onomatopoeic "zap" sound produced when an insect is electrocuted. How Does a Bug Zapper Work? Inside Poundland's electric fly zapper bat. Do cordless bug zapper zappers really work? Bug zappers are often housed in a protective cage of plastic or grounded metal bars to prevent folks or larger animals from touching the excessive voltage grid. A mild supply is fitted inside, often a fluorescent lamp designed to emit both visible and ultraviolet gentle, which is visible to insects and attracts a wide range of them. Newer fashions now use lengthy-life LEDs to supply the sunshine. The light supply is surrounded by a pair of interleaved naked wire grids or helices.
The distance between adjacent wires is usually about 2 mm (0.079 in). A excessive-voltage energy supply powered by wall power is used, which may be a simple transformerless voltage multiplier circuit made with diodes and capacitors which may generate a voltage of two kilovolts or more. This is high sufficient to conduct via the physique of an insect which bridges the two grids, but not high enough to spark throughout the air hole. Enough electric current flows by the small body of the insect to heat it to a high temperature. The impedance of the facility supply and the association of the grid is such that it cannot drive a harmful present through the body of a human. Many bug zappers are fitted with trays that accumulate the electrocuted insects
