A bug zapper, extra formally known as an electrical discharge insect management system, electric insect killer or (insect) electrocutor entice, is a device that attracts and kills flying insects which might be attracted by gentle. A gentle source attracts insects to an electrical grid, where they are electrocuted by touching two wires with a excessive voltage between them. The title 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 usually housed in a protecting cage of plastic or grounded steel bars to stop people or larger animals from touching the high voltage grid. A mild supply is fitted inside, Zap Zone Defender Device usually a fluorescent lamp designed to emit each seen and ultraviolet gentle, which is visible to insects and Zap Zone Defender attracts quite a lot of them. Newer fashions now use long-life LEDs to produce the light. The sunshine supply is surrounded by a pair of interleaved naked wire grids or helices.

The gap between adjacent wires is typically about 2 mm (0.079 in). A excessive-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 can generate a voltage of 2 kilovolts or extra. That is high enough to conduct by the body of an insect which bridges the 2 grids, but not high sufficient to spark throughout the air gap. Enough electric present flows via the small physique of the insect to heat it to a high temperature. The impedance of the facility provide and the association of the grid is such that it can't drive a dangerous current by means of the physique of a human. Many bug zappers are fitted with trays that accumulate the electrocuted insects; other fashions are designed to allow the debris to fall to the ground below. Some use a fan to help to entice the insect.
