One of our longtime vendors found this book entitled “Outwitting Squirrels: 101 Cunning Stratagems to Reduce Dramatically the Egregious Misappropriation of Seed from Your Birdfeeder by Squirrels” by Bill Adler, Jr. We are looking forward to checking it out!
Maybe in the 3rd edition, they can add a section on outwitting squirrels from eating your lead jacks by using SquirrelGard!
