No-Squirrel® brand wild bird food has been scientifically formulated to attract a full range of wild birds to your feeder, while keeping squirrels at bay. Squirrels can quickly damage or even destroy expensive bird feeders, while scaring off the very birds you are trying to attract. Each seed in No-Squirrel® has been coated with a natural extract of the pepper plant, that, while having no effect on birds, is very distasteful to squirrels. One bite and the squirrels will go running!
