A little chipmunk skipping through a garden is cute, but a chipmunk gang becomes a problem. The first step to deterring them is to limit their food supply. Chipmunks feed on spilled birdseed beneath feeders, and they steal food from pet food bowls. Although chipmunks love tulips and many other bulbs, they avoid eating daffodils. Plant plenty of those, as well as crocus, which they also leave alone. The second step is to add fencing. Would your garden look attractive enclosed with a small picket fence? If so, attach 1-2-inch hardware cloth, which resembles coarse window screening, to the back side of the fence. To keep chipmunks from burrowing into your no-chipmunk zone, bury the hardware cloth 6 inches belowground and extend it 2 feet above the ground. Hardware cloth comes in rolls-cut it with tin snips or wire cutters. A third step is to move the location of their nests. If chipmunk holes are present in your yard, their nests are quite close, because chipmunks seldom travel more than 50 feet from their burrows. Watch for them early in the morning and late in the afternoon, and see if you can locate their homes. If you discover that they're nesting beneath a woodpile or another source of cover, you may be able to move the cover-and the chipmunks-a good distance away from your garden.
