A bug zapper, extra formally known as an electrical discharge insect control system, UV bug zapper bug mosquito zapper electric insect killer or (insect) electrocutor trap, is a system that attracts and kills flying insects which can be attracted by gentle. A light supply attracts insects to an electrical grid, the place 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 mosquito zapper Work? Inside Poundland's electric fly zapper bat. Do bug zappers actually work? Bug zappers are normally housed in a protecting cage of plastic or grounded steel bars to forestall individuals or bigger animals from touching the high voltage grid. A gentle source is fitted inside, often a fluorescent lamp designed to emit both visible and ultraviolet light, which is visible to insects and attracts a variety of them. Newer fashions now use lengthy-life LEDs to supply the light. The light supply is surrounded by a pair of interleaved naked wire grids or helices.

The space between adjoining wires is often about 2 mm (0.079 in). A excessive-voltage power provide powered by wall energy is used, which may be a simple transformerless voltage multiplier circuit made with diodes and capacitors which might generate a voltage of 2 kilovolts or extra. This is high sufficient to conduct by means of the physique of an insect which bridges the 2 grids, however not excessive sufficient to spark across the air hole. Enough electric present flows by means of the small body of the insect to heat it to a excessive temperature. The impedance of the power provide and bug zapper for patio the association of the grid is such that it can't drive a harmful present by the body of a human. Many bug zappers are fitted with trays that acquire the electrocuted insects
