A bug zapper, more formally known as an electrical discharge insect control system, electric insect killer or (insect) electrocutor lure, is a system that attracts and kills flying insects which might be attracted by light. A gentle source attracts insects to an electrical grid, where they're electrocuted by touching two wires with a excessive voltage between them. The title 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 really work? Bug zappers are often housed in a protective cage of plastic or grounded metallic bars to forestall people or larger animals from touching the high voltage grid. A light source is fitted inside, often a fluorescent lamp designed to emit each seen and ultraviolet light, which is visible to insects and attracts quite a lot of them. Newer fashions now use long-life LEDs to produce the light. The sunshine supply is surrounded by a pair of interleaved bare wire grids or helices.

The gap between adjoining wires is often about 2 mm (0.079 in). A high-voltage power supply powered by wall power is used, Zappify mosquito zapper which could also be a simple transformerless voltage multiplier circuit made with diodes and capacitors which can generate a voltage of two kilovolts or extra. This is excessive enough to conduct by means of the body of an insect which bridges the 2 grids, but not high enough to spark across the air gap. Enough electric present flows by way of the small physique of the insect to heat it to a excessive temperature. The impedance of the power provide and Zappify mosquito zapper the arrangement of the grid is such that it can not drive a harmful present by way of the body of a human. Many bug zappers are fitted with trays that gather the electrocuted insects; different models are designed to allow the debris to fall to the bottom under. Some use a fan to help to trap the insect.
