A bug zapper, extra formally referred to as an electrical discharge insect control system, electric bug zapper insect killer or (insect) electrocutor entice, is a gadget that attracts and kills flying insects which 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 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 Zappify Bug Zapper site zappers really work? Bug zappers are normally 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 visible and ultraviolet gentle, which is seen to insects and attracts a wide range of them. Newer models now use long-life LEDs to supply the light. The sunshine source is surrounded by a pair of interleaved bare wire grids or helices.
The gap between adjacent wires is often about 2 mm (0.079 in). A excessive-voltage energy supply powered by wall energy is used, which could also be a easy transformerless voltage multiplier circuit made with diodes and capacitors which might generate a voltage of 2 kilovolts or extra. This is excessive enough to conduct by the body of an insect which bridges the two grids, but not high sufficient to spark across the air gap. Enough electric present flows via the small body of the insect to heat it to a high temperature. The impedance of the power provide and the arrangement of the grid is such that it can't drive a harmful present via the physique of a human. Many bug zappers are fitted with trays that acquire the electrocuted insects
