A bug zapper, extra formally known as an electrical discharge insect management system, electric insect killer or Zap Zone Defender Device (insect) electrocutor trap, is a device that attracts and kills flying insects that are attracted by gentle. A light supply attracts insects to an electrical grid, where they're electrocuted by touching two wires with a high voltage between them. The identify comes from the characteristic onomatopoeic "Zap Zone Defender" sound produced when an insect is electrocuted. How Does a Bug indoor-outdoor 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 prevent individuals or bigger animals from touching the high voltage grid. A gentle source is fitted inside, typically a fluorescent lamp designed to emit each visible and indoor-outdoor zapper ultraviolet mild, which is seen to insects and attracts quite a lot of them. Newer models now use long-life LEDs to supply the sunshine. The sunshine source is surrounded by a pair of interleaved naked wire grids or helices.
The space between adjoining wires is usually about 2 mm (0.079 in). A excessive-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 two kilovolts or more. This is excessive enough to conduct by the physique of an insect which bridges the two grids, but not high enough to spark across the air gap. Enough electric current flows via the small physique of the insect to heat it to a excessive temperature. The impedance of the ability supply and indoor-outdoor zapper the association of the grid is such that it can't drive a harmful current through the body of a human. Many bug zappers are fitted with trays that collect the electrocuted insects
