When moles enter homes, it’s typically by accident. Most infestations occur outdoors in gardens and yards. Since the pests are known for their tunneling behavior and live primarily in underground burrows, they generally need to stay outside in the soil. Nevertheless, residents may find moles in the house in basements and cellars from time to time. In most of these cases, the moles are invading older homes with dirt floors, cracks in the foundation, or gaps in the basement windows and panes.
