Each year, over 300,000 cases of Lyme disease are reported in the U.S. alone. Thermacell® Tick Control Tubes provide you with an easy way to kill off disease-carrying ticks in your yard or campsite. Just place the Tubes where mice frequently visit, like flowerbeds, bushes, woodpiles, stone walls, and sheds. The biodegradable, cardboard-filled Tubes contain cotton with a specially treated material that kills ticks. Mice will collect the cotton and use it as a nesting material to line their underground nests. When the ticks feed on these mice, they also feed on the treated material.
