How to identify Groundhogs

Groundhogs, also called woodchucks and whistle-pigs, like to graze and sun themselves in yards, fields, and meadows, and dig burrows in prairies, open forests, meadows, and pastures. However, they will gather in suburban neighbourhoods if food is plentiful.

They feed on grasses, clover, alfalfa, dandelions, snails, grasshoppers, grubs, berries, apples, lettuce, corn, carrots, and hackberry, mulberry, and maple leaves.

Signs of an infestation

A surefire way to know if you have a groundhog problem is by looking for signs of digging. Burrow holes and piles of dirt can indicate that a groundhog has taken up residence on your property. Destroyed crops and damage to ornamental plants from clawing and scent marking can also point to a groundhog infestation.

Habitat, Diet, and Life Cycle


Grazing habits, the availability of food, and seasonal changes all influence groundhogs in their quest to find a perfect denning spot. Summer burrows are often constructed near the middle of the home territory, while winter burrows are dug deep enough to stay below frost levels and are usually located near protective cover. Prairies, open forests, meadows, and pastures are all ideal sites. Contrary to other species of pest animals, the building of roads, clearing of forests, and planting of fields have actually helped groundhog populations grow.


The diet of the groundhog consists mainly of the vegetation surrounding its home. This includes clover, grasses, weeds, and flowers. Other food sources include tree bark, bird eggs, and small invertebrates. Groundhogs mainly feed during the day and sleep at night. As an animal that hibernates, groundhogs are known to store fat as winter approaches.

Life Cycle

Female groundhogs give birth to litters of three to five pups. Young groundhogs are known to wean very early and leave the mother by the time they reach two months of age. Sexual maturity usually occurs within the first two years of life, and most groundhogs live for about five years in the wild. Due to factors like predation and disease, that lifespan can be much shorter.
