A bug zapper, extra formally called an electrical discharge insect control system, electric insect killer or (insect) electrocutor trap, is a machine that attracts and kills flying insects which can be attracted by light. A mild supply attracts insects to an electrical grid, the place they're electrocuted by touching two wires with a high voltage between them. The name comes from the characteristic onomatopoeic "Zap Zone Defender Testimonial" sound produced when an insect is electrocuted. How Does a Bug Zapper Work? Inside Poundland's electric fly zapper bat. Do bug zappers really work? Bug zappers are often housed in a protecting cage of plastic or grounded metal bars to forestall people or bigger animals from touching the high voltage grid. A gentle source is fitted inside, often a fluorescent lamp designed to emit both visible and ultraviolet gentle, which is visible to insects and attracts quite a lot of them. Newer fashions now use lengthy-life LEDs to produce the sunshine. The sunshine source is surrounded by a pair of interleaved bare wire grids or helices.

The gap between adjoining wires is often about 2 mm (0.079 in). A excessive-voltage power supply 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 2 kilovolts or extra. This is excessive sufficient to conduct by way of the physique of an insect which bridges the 2 grids, however not high sufficient to spark throughout the air gap. Enough electric current flows by the small physique of the insect to heat it to a excessive temperature. The impedance of the facility provide and the association of the grid is such that it can't drive a dangerous present by way of the body of a human. Many bug zappers are fitted with trays that gather the electrocuted insects
