A bug zapper is an electronic device designed to attract and kill flying insects, particularly mosquitoes and flies. It typically uses ultraviolet (UV) light to lure bugs, which are then electrocuted by a high-voltage grid. Bug zappers are commonly used in outdoor settings, such as backyards and patios, to reduce insect populations. These devices come in various sizes and designs, including portable models and larger units for commercial use. While effective at killing insects, bug zappers may not significantly reduce mosquito populations, as they primarily attract non-biting species. Proper placement and maintenance are essential for optimal performance.
