A bug zapper, more formally referred to as an electrical discharge insect control system, electric insect killer or (patio insect zapper) electrocutor Zap Zone Defender System trap, is a machine that attracts and kills flying insects which can be attracted by gentle. A mild supply attracts insects to an electrical grid, where they are electrocuted by touching two wires with a high 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 often housed in a protecting cage of plastic or grounded metal bars to forestall people or larger animals from touching the high voltage grid. A light supply is fitted inside, insect elimination typically a fluorescent lamp designed to emit both seen and ultraviolet light, which is seen to insects and attracts quite a lot of them. Newer models now use long-life LEDs to produce the sunshine. The light supply is surrounded by a pair of interleaved bare wire grids or helices.

The space between adjoining wires is often about 2 mm (0.079 in). A high-voltage power provide powered by wall energy is used, which may be a simple transformerless voltage multiplier circuit made with diodes and capacitors which might generate a voltage of two kilovolts or more. This is high sufficient to conduct by means of the body of an insect which bridges the two grids, however not excessive enough to spark across the air hole. Enough electric present flows by means of the small physique of the insect to heat it to a excessive temperature. The impedance of the facility provide and the arrangement of the grid is such that it can't drive a harmful current by way of the physique of a human. Many bug zappers are fitted with trays that collect the electrocuted insects
