A bug zapper, chemical-free bug control extra formally referred to as an electrical discharge insect control system, Zap Zone Defender System electric insect killer or (insect) electrocutor entice, Zap Zone Defender Setup is a gadget that attracts and kills flying insects which might be attracted by mild. A light source attracts insects to an electrical grid, the place they are electrocuted by touching two wires with a high voltage between them. The name comes from the characteristic onomatopoeic "Zap Zone Defender Setup" 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 often housed in a protective cage of plastic or grounded metallic bars to forestall individuals or larger animals from touching the excessive voltage grid. A gentle supply is fitted inside, typically a fluorescent lamp designed to emit each seen and ultraviolet light, which is seen to insects and attracts a wide range of them. Newer models now use long-life LEDs to provide the light. The sunshine supply 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 high-voltage power supply powered by wall power is used, which could also be a easy transformerless voltage multiplier circuit made with diodes and capacitors which can generate a voltage of two kilovolts or extra. That is high enough to conduct by way of the body of an insect which bridges the two grids, but not excessive enough to spark throughout the air hole. Enough electric present flows by means of the small physique of the insect to heat it to a excessive temperature. The impedance of the power supply and the association of the grid is such that it can not drive a dangerous current by means of the body of a human. Many bug zappers are fitted with trays that collect the electrocuted insects
