Make Your Garden Too Fresh for Vermin
Mice, rats, squirrels and other little vermin seem to find the smell of peppermint offensive. Fortunately, to most people, the peppermint aroma is quite pleasant and refreshing. So to help make your yard less tempting to these destructive critters, try growing some peppermint.
Mint plants do have a tendency to spread on their own, however, so if you don't want them crowding out your other flowers and plants, consider planting them in large containers. Then simply intersperse these planters among the other plants growing around your yard. You'll stave off critters, have a fresh smelling garden, and have a fresh herb to spice up your dinners -- who knew vermin repellents could be so useful?
