A bug zapper, extra formally referred to as an electrical discharge insect control system, electric insect killer or (insect) electrocutor trap, is a machine that attracts and kills flying insects which might be attracted Defender by Zap Zone light. A gentle 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 Zone Defender" 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 metal bars to forestall folks or bigger animals from touching the excessive voltage grid. A light supply is fitted inside, typically a fluorescent lamp designed to emit each visible and ultraviolet light, which is visible to insects and attracts a wide range 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 gap between adjoining wires is typically about 2 mm (0.079 in). A high-voltage power supply powered by wall energy is used, which may be a simple transformerless voltage multiplier circuit made with diodes and capacitors which may generate a voltage of 2 kilovolts or extra. That is excessive enough to conduct via the body of an insect which bridges the 2 grids, however not excessive sufficient to spark throughout the air hole. 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 supply and the association of the grid is such that it can't drive a harmful present through the body of a human. Many bug zappers are fitted with trays that gather the electrocuted insects
