Operating principle: Mosquitoes are phototaxis, and the mosquito trap lamp's beads emit light to attract them. Additionally, the micro-temperature effect simulates a humid, carbon dioxide atmosphere, and the fan stirs the surrounding air to create a vortex (mode 3). Once a mosquito is drawn into the capture window, it cannot escape the vortex and is not captured. After approximately one month, the mosquitoes die from dehydration.Safety and health: The mosquito killer uses ultraviolet light to attract mosquitoes, fruit flies, gnats, moths, insects, and other flying insects into the lamp. The mosquito trap is non-toxic, chemical-free, and silent. Ideal for nurseries, maternity wards, and adults, protecting human health and environmental safety.Simple and portable: The flying mosquito lamp's interface is USB, compatible with various USB adapters such as power banks, computers, laptops, etc., and can also be used with a power bank or laptop when camping. Perfect for home, office, kitchen, restaurant, school, hospital, patio, yard, and more.Maintenance: The electric fly killer is designed with a removable tray at the bottom of the device to collect dead flies. When you need to clean and disinfect the mosquito trap, simply twist and open the container underneath, empty the container to dispose of the mosquitoes, then rinse and disinfect.
