Distraction is key to keeping pesky squirrels from raiding your bird feeder, and this contraption has mastered it. Attach ears of corn, fruit or peanut butter to the dowels. As the squirrels go for the food, their weight causes the dowels to spin. And that’s when the fun begins. Mount on a tree, post or fence. Some assembly required. Kit includes wooden dowels, a hub and screws. USA. Hub: 3.25"Diam.; dowels 12"L.
