There are several mole species in North America but the Eastern Mole is one of the most common to be considered a pest. These blind beauties live under ground and dig a network of tunnels and chambers. Moles are small, weighing in at only about 3-5 oz. and are about 6-8 inches long. Don’t let their small size fool you. They are great diggers and have a voracious appetite. They primarily eat earthworms and other underground insects. Most moles are territorial and breed in the winter. They live for about 3 years. They are usually considered a pest due to their digging.
