A bug zapper, extra formally called an electrical discharge insect management system, electric insect killer or ZapZone Defender (insect) electrocutor trap, is a system that attracts and kills flying insects which are attracted by gentle. A mild supply attracts insects to an electrical grid, the place they’re electrocuted by touching two wires with a excessive voltage between them. The name comes from the characteristic onomatopoeic “Zap Zone Defender USA” 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 protective cage of plastic or grounded metallic bars to stop individuals or larger animals from touching the excessive voltage grid. A gentle source is fitted inside, often a fluorescent lamp designed to emit both visible and ultraviolet mild, which is visible to insects and attracts quite a lot of them. Newer models 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 space 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 might generate a voltage of 2 kilovolts or more. This is high sufficient to conduct via the body of an insect which bridges the 2 grids, but not high enough to spark across the air hole. 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 present by way of the physique of a human. Many bug zappers are fitted with trays that collect the electrocuted insects
