A bug zapper, more formally called an electrical discharge insect management system, electric insect killer or (insect) electrocutor lure, is a system that attracts and kills flying insects which are attracted by mild. A light supply attracts insects to an electrical grid, the place they're electrocuted by touching two wires with a high voltage between them. The identify 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 protecting cage of plastic or grounded metallic bars to forestall people or rechargeable bug zapper larger animals from touching the excessive voltage grid. A gentle source is fitted inside, often a fluorescent lamp designed to emit each visible and ultraviolet mild, which is visible to insects and attracts a variety of them. Newer fashions now use lengthy-life LEDs to provide the light. The light supply is surrounded by a pair of interleaved bare wire grids or helices.

The space between adjoining wires is usually about 2 mm (0.079 in). A excessive-voltage power provide powered by wall energy is used, which could also be a simple transformerless voltage multiplier circuit made with diodes and capacitors which may generate a voltage of two kilovolts or more. That is excessive enough to conduct by the body of an insect which bridges the 2 grids, but not high sufficient to spark across the air hole. Enough electric current flows through the small physique of the insect to heat it to a excessive temperature. The impedance of the facility provide and the arrangement of the grid is such that it can not drive a harmful present by means of the body of a human. Many rechargeable bug zapper zappers are fitted with trays that gather the electrocuted insects
