Yep, you read that right. This is birdseed formulated with hot peppers! While completely safe (and tasty) to birds, the spice in this birdseed makes it intolerable to the most menacing of backyard critters: squirrels. So, if you love feeding birds and welcoming our stunning avian friends into your outdoor areas but would prefer not to feed every squirrel in the neighborhood, give this stuff a try. It has worked wonders for us!
