A simple, effective alternative to the arm-flailing method of shooing away deer flies and horseflies, this decoy mimics the look and behavior of their voracious predator, the dragonfly. Clipped to your hat or backpack with the metal clip, it waggles and bobs on its wire, imitating a dragonfly’s natural quick, unpredictable flight patterns, to ward off flies with the illusion of a threat. Designed in Canada and tested in Ontario’s cottage country, it comes in various colors, depending on supply.
