A bug zapper, more formally referred to as an electrical discharge insect control system, electric bug zapper insect mosquito killer or (insect) electrocutor lure, is a device that attracts and kills flying insects that are attracted by gentle. A gentle supply attracts insects to an electrical grid, where they are 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 cordless bug zapper zappers actually work? Bug zappers are usually housed in a protective cage of plastic or grounded metallic bars to forestall folks or larger animals from touching the excessive voltage grid. A mild supply is fitted inside, typically a fluorescent lamp designed to emit both seen and buy Zappify Bug Zapper ultraviolet gentle, which is visible to insects and attracts a variety of them. Newer models now use lengthy-life LEDs to supply the sunshine. The light source is surrounded by a pair of interleaved bare wire grids or helices.

The space between adjoining wires is often about 2 mm (0.079 in). A excessive-voltage power provide powered by wall power is used, which could also be a simple transformerless voltage multiplier circuit made with diodes and capacitors which might generate a voltage of 2 kilovolts or extra. That is high sufficient to conduct via the physique of an insect which bridges the 2 grids, but not high enough to spark across the air hole. Enough electric present flows by means of the small physique of the insect to heat it to a high temperature. The impedance of the power supply and the association of the grid is such that it can't drive a harmful current by way of the body of a human. Many buy Zappify Bug Zapper zappers are fitted with trays that collect the electrocuted insects
