Just a tablespoon of Squirrel Away mixed with 5 pounds of birdseed is enough to make squirrels run from your feeder. Made from capsaicin, which is the spicy part of chili peppers. Squirrel Away is despised by mammals but completely odorless and tasteless to birds. In fact it is an excellent source of Vitamin A for them. One 1.5 oz. package of Squirrel Away treats 25 lbs of birdseed. Due to changes in shipping regulations, we cannot ship this item to California.
