Geepas is a non-polluting automatic electric bug killer. AUTOMATIC FUNCTIONING: This bug killer works automatically. Houseflies and mosquitoes are attracted by the unique color of the UV light and octanol and fly towards the tubes. When the bug comes in contact with one of its tubes, it is immediately killed by the electrified rod. Non-polluting, healthy, and lightweight, this mosquito killer poses no health hazards; however, children should avoid going near it. As the rods are electrified, they can be dangerous if touched carelessly. This device is lightweight and can easily be hung at your desired location. The light is strong enough to attract insects but not too strong to disturb your sleep at night. Two 20-watt tubes are fixed inside. Each is an ultra-violet light with a bright purple glow.
