Chipmunks are a common species of ground squirrel. They thrive where ever they can feed on bird seed, spring flower bulbs, acorns and various seeds. Due to the abundance of food, they seem to be even more plentiful in urban and suburban areas than in the forest. They live in underground burrows beneath sidewalks, patios, porches and retaining walls. Usually chipmunks cause no harm to landscape and vegetable plants. But, when their populations become high, they may eat buds from woody plants, bulbs and their blossoms. Their system of tunnels and burrows may also cause paved surfaces to settle and crack.

If control is needed, you can reduce their population by using snap-type rat traps. Protect emerging spring bulbs by covering with chicken wire. Natural predators such as foxes and snakes also help to maintain a balanced population of chipmunks.
