The Yes-o Mosquito Catcher Insect Killer YIK-04 is a home appliance designed to eliminate flying insects, particularly mosquitoes. It uses a combination of UV light to attract insects and an electric grid to kill them on contact. The device is a "non-poison, non-smell, non-pollution" solution for insect control, making it a healthful choice for indoor use. It typically features two 15W UV lamps, for a total of 30W of power, and a high-voltage transformer for effective zapping. The YIK-04 is a static unit, not a handheld racket, and is meant to be placed in a room to continuously attract and kill insects.
