Pine Tree Farms Insect Suet Cake is a wonderful treat for the feathered visitors in your backyard. This hand-crafted, 100% edible suet is made from rendered beef suet and blended with ground peanuts, finely cracked corn, and nutritious black soldier fly larvae-making it a high-fat, high-protein snack birds adore. You can use this suet cake in standard suet feeders or combination seed-and-suet feeders, giving you plenty of options for welcoming more wildlife. Just place the suet cake in your feeder and get ready to enjoy the colorful parade of bluebirds, chickadees, grosbeaks, jays, kinglets, nuthatches, titmice, warblers, woodpeckers, wrens, and many others that will happily stop by for a bite.
