A **mosquito zapper** is an electronic device designed to eliminate flying pests using a combination of light and electricity. It typically utilizes ultraviolet (UV) light to lure mosquitoes and other insects toward an internal high-voltage metal grid. Upon contact, the grid delivers a swift electric shock, instantly neutralizing the insect. While many models are designed for outdoor use to clear patios and decks, compact indoor versions are also common. Modern zappers often feature protective outer housings to prevent accidental contact by humans or pets, providing a chemical-free alternative to traditional bug sprays and repellents.
