A bug zapper, more formally called an electrical discharge insect management system, electric insect killer or Official Zap Zone Defender (insect) electrocutor entice, is a device that attracts and Official Zap Zone Defender kills flying insects which are attracted by light. A mild supply attracts insects to an electrical grid, the place they are electrocuted by touching two wires with a high voltage between them. The identify comes from the characteristic onomatopoeic "Official 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 stop folks or larger animals from touching the high voltage grid. A gentle source is fitted inside, typically a fluorescent lamp designed to emit each seen and Official Zap Zone Defender ultraviolet mild, which is seen to insects and attracts a variety of them. Newer models now use long-life LEDs to provide the light. The light source is surrounded by a pair of interleaved naked wire grids or helices.

The distance between adjoining wires is usually about 2 mm (0.079 in). A high-voltage power supply powered by wall power is used, which may be a easy transformerless voltage multiplier circuit made with diodes and capacitors which might generate a voltage of 2 kilovolts or more. That is excessive enough to conduct through the body of an insect which bridges the two grids, insect zapper however not high enough to spark throughout the air hole. Enough electric present flows through the small body of the insect to heat it to a excessive temperature. The impedance of the power provide and the association of the grid is such that it can't drive a dangerous present by the physique of a human. Many bug zappers are fitted with trays that gather the electrocuted insects
