A bug zapper, more formally known as an electrical discharge insect management system, electric insect killer or Zap Zone Defender Testimonial (insect) electrocutor entice, is a gadget that attracts and kills flying insects which can be attracted by mild. A light supply attracts insects to an electrical grid, Zap Zone Defender where they're electrocuted by touching two wires with a excessive voltage between them. The identify 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 normally housed in a protecting cage of plastic or grounded metal bars to stop folks or larger animals from touching the excessive voltage grid. A light supply is fitted inside, often a fluorescent lamp designed to emit both seen and ultraviolet gentle, which is visible to insects and attracts a variety of them. Newer fashions now use lengthy-life LEDs to supply the sunshine. The light source 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 provide powered by wall power is used, which may be a easy transformerless voltage multiplier circuit made with diodes and capacitors which can generate a voltage of two kilovolts or more. This is excessive sufficient to conduct by the physique of an insect which bridges the 2 grids, however not excessive sufficient to spark throughout the air gap. Enough electric present flows through the small physique of the insect to heat it to a high temperature. The impedance of the power supply and the arrangement of the grid is such that it can not drive a dangerous current via the body of a human. Many bug zappers are fitted with trays that gather the electrocuted insects
