A bug zapper, extra formally referred to as an electrical discharge insect control system, electric insect killer or (insect) electrocutor entice, is a device that attracts and kills flying insects that are attracted by mild. A gentle source attracts insects to an electrical grid, where they are electrocuted by touching two wires with a high voltage between them. The name comes from the characteristic onomatopoeic "Zap Zone Defender" sound produced when an insect is electrocuted. How Does a Bug Zapper Work? Inside Poundland's electric fly zapper bat. Do bug zappers really work? Bug zappers are usually housed in a protective cage of plastic or grounded steel bars to forestall people or larger animals from touching the excessive voltage grid. A mild supply is fitted inside, usually a fluorescent lamp designed to emit both seen and chemical-free bug control ultraviolet mild, which is visible to insects and attracts a wide range of them. Newer models now use lengthy-life LEDs to provide the light. The sunshine supply is surrounded by a pair of interleaved naked wire grids or helices.

The gap between adjacent wires is typically about 2 mm (0.079 in). A high-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 may generate a voltage of 2 kilovolts or extra. That is excessive sufficient to conduct through the physique of an insect which bridges the two grids, however not high enough to spark throughout the air hole. Enough electric present flows via the small physique of the insect to heat it to a high temperature. The impedance of the ability supply and the arrangement of the grid is such that it can't drive a harmful present by the body of a human. Many bug zappers are fitted with trays that collect the electrocuted insects
