Chipmunks are cute and can be destructive to wires, gardens, lawns and foundations when they multiply. You can try baiting them with peanut butter in traps and relocate. They also sell repellent in stores to spray on trouble areas. Some people when RVing throw mothballs under them to repel the chipmunks from chewing their lines. You can also encase the wires with mesh wire or a box where possible. The last resort is an exterminator.
