Image shows an electric UV mosquito killer lamp, also known as a bug zapper or insect killer. Functionality: It uses UV-A light to attract flying insects like mosquitoes, flies, and moths, and then eliminates them with a high-voltage inner grid. Features: It typically includes a collection tray for easy cleaning and is designed for indoor use. Effectiveness: The UV-A tube emits a specific wavelength (e.g., 365nm) to maximize attraction, and some models have an enlarged grid for increased killing efficiency. Safety: It offers a poison-free method of insect control, making it suitable for various indoor spaces.
