The Squirrel Buster Nut Feeder is mainly meant for hulled peanuts, but you can use a variety of other nuts, mealworms, or even dried fruit. The newest addition to this feeder is a second smaller mesh that you can interchange. This now allows you to use sunflower seeds! The smaller mesh is also great to use when the grackles are around, as they have little patience for clinging and pecking. Like most of the other Squirrel Busters, the Nut Feeder is adjustable and also really easy to fill, take apart, and clean! Stop by soon to check it out!
