It fits to your belt and repel bugs within a 15 feet radius wherever you are on the go. “Eliminating the need to apply chemical-based sprays, the device automatically emits the subtle floral scent of geraniol, a plant-derived essential oil that naturally repels mosquitoes, ticks, and no see-ums.”

In fact research at the University of Florida indicates that this tiny gadget is even more effective that DEET, the chemical widely used in most bug repellents. All it requires is a pair of AA batteries.
