A bug zapper, Zap Zone Defender Review extra formally known as an electrical discharge insect management system, electric insect killer or (insect) electrocutor entice, is a machine that attracts and kills flying insects which can be attracted by light. A gentle source attracts insects to an electrical grid, where they're electrocuted by touching two wires with a high voltage between them. The name comes from the characteristic onomatopoeic "Zap Zone Defender Review" 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 Zap Zone Defender Review grounded metal bars to forestall people or larger animals from touching the excessive voltage grid. A light supply is fitted inside, typically a fluorescent lamp designed to emit both seen and ultraviolet light, which is visible to insects and attracts a variety of them. Newer fashions now use lengthy-life LEDs to provide the light. The light source is surrounded by a pair of interleaved bare wire grids or helices.

The gap between adjacent wires is typically about 2 mm (0.079 in). A high-voltage energy provide powered by wall energy is used, which could also be a simple transformerless voltage multiplier circuit made with diodes and capacitors which can generate a voltage of 2 kilovolts or chemical-free bug control extra. This is excessive sufficient to conduct via the physique of an insect which bridges the two grids, but not high enough to spark throughout the air gap. Enough electric present flows by the small body of the insect to heat it to a high temperature. The impedance of the power provide and the arrangement of the grid is such that it cannot drive a harmful present through the physique of a human. Many bug zappers are fitted with trays that accumulate the electrocuted insects
