Moles burrow year-round, creating more shallow tunnels for spring, summer and fall, then deep tunnels for the winter months. They can tunnel very quickly, around one foot per hour in ideal conditions. They prefer sandy soil, moist earth, lawns, gardens and woodlands. They typically are not found in heavy, dry clay soil. Their eyesight is terrible and they are very sensitive to light. The only time you would ever see them running above ground (if ever) would be at night. They prefer solitude, and will not ideally share a tunnel with other moles. Shrews, gophers and voles, however, typically try to invade their perfect tunnels.
