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 areas like patios and gardens to reduce insect populations. These devices come in various sizes and designs, including portable models and larger units for commercial use. While effective, bug zappers primarily target certain insects and may not significantly reduce overall pest populations. They are often used alongside other pest control methods for better results.
