An outdoor bug zapper is a high-efficiency electronic device designed to clear patios, decks, and yards of flying pests like mosquitoes, flies, and moths. It utilizes a powerful **ultraviolet (UV) light** to lure insects toward an electrified internal metal grid, where they are instantly eliminated upon contact. Built with weather-resistant housings to withstand rain and humidity, these devices often feature a protective outer cage to prevent accidental contact by pets or birds. While highly effective at reducing insect populations in localized areas, they are most successful when placed away from seating zones to draw bugs away from people.
