A bug zapper, extra formally referred to as an electrical discharge insect management system, ZapZone Defender electric insect killer or (insect) electrocutor entice, is a machine that attracts and kills flying insects which might be attracted by mild. A light source attracts insects to an electrical grid, the place they are electrocuted by touching two wires with a excessive voltage between them. The identify comes from the characteristic onomatopoeic "Zap Zone Defender USA" 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 usually housed in a protective cage of plastic or Zap Zone Defender USA grounded metallic bars to forestall folks or Zap Zone Defender USA larger animals from touching the high voltage grid. A light supply is fitted inside, often a fluorescent lamp designed to emit both seen and ultraviolet gentle, which is seen to insects and attracts quite a lot 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 distance between adjoining wires is often about 2 mm (0.079 in). A high-voltage energy supply powered by wall power is used, which could also 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 sufficient to conduct by way of the physique of an insect which bridges the two grids, however not excessive enough to spark across the air hole. Enough electric present flows via the small body of the insect to heat it to a high temperature. The impedance of the facility supply and the association of the grid is such that it cannot drive a dangerous current via the body of a human. Many bug zappers are fitted with trays that accumulate the electrocuted insects
