I use garlic powder. You can buy a large bag (5 Lbs?) from Amazon. It is cheaper in bulk, a lot better than those little bottles you buy for the kitchen. Squirrels do not like the smell. I can't shoot them because they seldom come above ground until the weather warms. They eat the roots of my plants, mostly Hollyhocks. I have desert ground squirrels (I think) that are about the size of a chipmunk. They could be gophers the way they tunnel everywhere, even in the hard desert soil between my raised beds.
