A bug zapper, extra formally referred to as an electrical discharge insect control system, electric bug zapper insect killer or (insect) electrocutor trap, is a gadget that attracts and kills flying insects that are attracted by mild. A mild supply attracts insects to an electrical grid, where they are 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 bug zappers actually work? Bug zappers are usually housed in a protective cage of plastic or grounded metal bars to forestall folks or rechargeable bug zapper bigger animals from touching the high voltage grid. A light supply is fitted inside, rechargeable bug zapper often a fluorescent lamp designed to emit each visible and ultraviolet light, mosquito zapper which is visible to insects and attracts a variety of them. Newer models now use long-life LEDs to supply the light. The light source is surrounded by a pair of interleaved bare wire grids or helices.

The gap between adjacent wires is usually about 2 mm (0.079 in). A high-voltage power 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 2 kilovolts or extra. This is high sufficient to conduct by means of the body of an insect which bridges the 2 grids, however not high enough to spark throughout the air hole. Enough electric present flows through the small body of the insect to heat it to a high temperature. The impedance of the facility provide and the association of the grid is such that it can not drive a dangerous present via the body of a human. Many bug zappers are fitted with trays that accumulate the electrocuted insects
