Groundhogs dig tunnel systems that can damage structures.
They build underground dens and often hide beneath sheds or wooden structures. If you have seen a groundhog beneath your shed, it has likely established a home there.
Groundhogs and skunks very often share the same shelter.
A groundhog's holes beneath a shed or entrance may also provide access for skunks.
Groundhogs may eat plants, fruit and vegetables from gardens. Because they rarely travel far from their den, a reliable food source will keep them nearby.
Groundhogs live in colonies whose territory may extend across several neighbouring properties. Litters usually contain three to five young. Mating generally occurs in May and births in June after a 33-day gestation period.
The young begin leaving the den after about four weeks while consuming both their mother's milk and solid food. They gradually become more independent and explore their surroundings.
At around two months, young groundhogs are generally ready to leave the den and live independently.
