A bug zapper, Zappify Bug Zapper extra formally referred to as an electrical discharge insect control system, electric insect killer or (insect) electrocutor lure, is a system that attracts and kills flying insects that are attracted by gentle. A gentle 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" 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 often housed in a protective cage of plastic or grounded steel bars to stop people or bigger animals from touching the excessive voltage grid. A gentle supply is fitted inside, often a fluorescent lamp designed to emit both visible and ultraviolet mild, which is visible to insects and attracts a variety of them. Newer fashions now use lengthy-life LEDs to provide the light. The sunshine supply is surrounded by a pair of interleaved naked wire grids or helices.

The space between adjoining wires is typically about 2 mm (0.079 in). A excessive-voltage power supply powered by wall energy is used, 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 through the physique of an insect which bridges the 2 grids, however not high sufficient to spark across the air gap. Enough electric present flows by way of the small physique of the insect to heat it to a high temperature. The impedance of the facility provide and the association of the grid is such that it can't drive a harmful current by means of the physique of a human. Many bug zappers are fitted with trays that gather the electrocuted insects
