A portable bug zapper zapper, more formally called an electrical discharge insect management system, electric insect mosquito killer or (insect) electrocutor entice, is a gadget that attracts and kills flying insects that are attracted by mild. A mild source attracts insects to an electrical grid, where they're electrocuted by touching two wires with a high 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 bug zappers actually work? Bug zappers are normally housed in a protective cage of plastic or grounded metallic bars to forestall individuals or larger animals from touching the excessive voltage grid. A mild source is fitted inside, usually a fluorescent lamp designed to emit each visible and ultraviolet mild, which is seen to insects and attracts quite a lot of them. Newer models now use lengthy-life LEDs to supply the light. The sunshine supply is surrounded by a pair of interleaved bare wire grids or helices.

The distance between adjoining wires is usually 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 via the physique of an insect which bridges the 2 grids, rechargeable bug zapper 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 excessive temperature. The impedance of the power supply and the arrangement of the grid is such that it cannot drive a harmful present by means of the physique of a human. Many cordless bug zapper zappers are fitted with trays that accumulate the electrocuted insects
