Tred-Not Deer Fly Patches 4-Pack

Deerfly Patches are 2" by 6" flesh-colored traps that attach to the back of the cap or hat. Deer flies target the patch and are quickly caught. They are no longer a nuisance flying around your head or biting. Deerfly Patches have been field tested by Ohio State University and the Michigan Department of Fisheries and Wildlife. People like them because they have no chemicals and no odor, nothing greasy to rub or spray on your skin. Tred-Not has studied deer flies intensively for nearly thirty years and have done extensive research and testing on their biting habits. They have tested all insect repellents....they don't work effectively on deer flies. In the development of their Deerfly Patches, they have tested and proven different habits of the deer fly to determine why they bite some people more than others. They have experimented with carbon dioxide emissions, body heat emissions, motion and non-motion, clothing colors, reflective objects, smooth and furry surfaces, body odors, as well as environmental conditions... location, time of day, sunshine/cloudy, warm/cool, etc. From their research and development, they have created the best control for deer flies.
