A bug zapper, extra formally referred to as an electrical discharge insect management system, electric insect zapper killer or (insect) electrocutor trap, is a machine that attracts and kills flying insects which can be attracted by light. A mild supply attracts insects to an electrical grid, where they are electrocuted by touching two wires with a excessive 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? best bug zapper zappers are normally housed in a protective cage of plastic or grounded metallic bars to prevent folks or larger animals from touching the excessive voltage grid. A mild source is fitted inside, typically a fluorescent lamp designed to emit each visible and ultraviolet mild, which is seen to insects and attracts a wide range of them. Newer fashions now use long-life LEDs to produce the light. The sunshine supply is surrounded by a pair of interleaved bare wire grids or helices.

The gap between adjoining wires is typically about 2 mm (0.079 in). A high-voltage energy provide powered by wall power is used, Zappify Bug Zapper brand which could also be a easy transformerless voltage multiplier circuit made with diodes and capacitors which can generate a voltage of two kilovolts or extra. This is excessive sufficient to conduct via the physique of an insect which bridges the 2 grids, but not excessive sufficient to spark throughout the air gap. Enough electric current flows through the small body of the insect to heat it to a excessive temperature. The impedance of the facility supply and the arrangement of the grid is such that it can not drive a dangerous current by means of the body of a human. Many bug zappers are fitted with trays that collect the electrocuted insects
