It does repell mosquito - Thermacell Backpacker Mosquito Repeller

The working principle of this device is to warm the mosquito repellant by a very soft candle fire which consumes very little gas. When the device is properly setup, the mosquitos, when entering the nearby area, would become a fool and forget to land on human skins! They look like forget what to do and leave us alone! very interesting! It is the experience when I first use. I am not sure if it will be the same for all situation but my first experience is that it works.
