A bug zapper, more formally called an electrical discharge insect control system, electric insect mosquito killer or (insect) electrocutor trap, is a system 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 excessive 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 Zappify Bug Zapper shop zappers actually work? Bug zappers are often housed in a protecting cage of plastic or grounded metal bars to prevent individuals or larger animals from touching the excessive voltage grid. A gentle source is fitted inside, usually a fluorescent lamp designed to emit both seen and ultraviolet mild, which is seen to insects and attracts a wide range of them. Newer models now use lengthy-life LEDs to supply the sunshine. The sunshine 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 may be a easy transformerless voltage multiplier circuit made with diodes and capacitors which might generate a voltage of 2 kilovolts or more. This is high enough to conduct through the physique of an insect which bridges the 2 grids, however not excessive sufficient to spark throughout the air gap. Enough electric present flows by means of the small body of the insect to heat it to a excessive temperature. The impedance of the ability provide and the arrangement of the grid is such that it can not drive a harmful present by the body of a human. Many bug zappers are fitted with trays that acquire the electrocuted insects
