Groundhogs, also known as woodchucks, are a large species of rodents. These wild animals are only found in North America, and can live as far south as Alabama and have lived as far north as Alaska.
They are referred to as “edge dwellers” and prefer to live in areas such as woodlands and forests in winter and fall, and in open fields, grasslands, and suburban backyards in summer and spring. It is rare that a groundhog will move more than 0.5 miles from its burrow.
However, as urbanization is affecting the natural habitats of wildlife, including groundhogs, these animals made our towns and cities their home. They are getting more adapted to urban settings, are less and less frightened of humans and keep burrowing even when humans are around.
Do Groundhogs Live in the Ground?
As the name would suggest, groundhogs live inside the ground. Their holes lead to the underground burrows that they call home. This is where they spend most of their time. Groundhogs use these tunnels as a place to stay safe from predators, and as an ideal place for hibernation and raising their kits.
Are Groundhogs Problematic?
Just like other rodents, the groundhog’s teeth never stop growing. Their two chisel-shaped, long incisors can grow up to 1/16th of an inch per week. To keep these teeth at a reasonable length, groundhogs need to consume a large volume of food to wear their teeth down.
However, this isn’t usually the main problem for homeowners. The primary nuisance concern in regards to groundhogs involves their tendency to dig.
Groundhogs have muscular bodies, powerful short legs, and sharp claws which enables them to dig deep burrows. They accomplish building their burrows extremely well, and this is why they are sometimes called the “underground architects”.

What Do Groundhog Holes Look Like?
All groundhog burrows are laid out in practically the same way. Typically, these burrows will have one and sometimes two main entrances with up to six exits. These entrances look like large crescent-shaped mounds of excavated soil and dirt that’s placed right outside the entrance hole. A groundhog hole will appear roughly ten to twelve inches in diameter. The burrow also has one up to four secondary entrances.
The burrows can reach up to 50 feet in length but tend to be no deeper than 6 feet. When a groundhog starts building its burrow, it digs inward for several feet, and then it inclines the tunnel upward for a few more feet. After that, it will continue digging horizontally for another 15 to 25 feet.
These burrows are extensive, with numerous chambers used separately as a latrine as well as for sleeping, hibernating, and nesting.
Can Groundhogs Damage Your Property?
Groundhogs are definitely something that homeowners need to worry about. Their tunneling systems might lead to significant damage to your property.
These animals are able to dig and move a great amount of dirt, and when this activity happens near a house structure, for example under a concrete deck or a patio, the absence of supporting dirt might cause a vulnerable foundation that is prone to cracking.
They feel safe building homes under or around houses as the structure provides overhead stability for them. However, due to the tunneling nature of groundhog burrows, water damage and erosion can become a serious issue for the homeowner.
With rainy weather, these tunnels can fill with water and lead to water flowing directly underneath the house. This can lead to issues with the foundation, i.e. disruption of the existing water balance, and drainage problems during severe weather conditions.
You may find increased moisture in the basement which can, in turn, lead to mold developing throughout the building. The water-logged tunnels can cause the soil to become eroded, which may lead to the entire failure of the house’s foundation.
Due to their powerful teeth and big appetites, groundhogs can also do damage to crops and plants in your garden. For this reason, you may want to get rid of this wildlife before your garden gets destroyed.
Fortunately, there are ways that a homeowner can deter groundhogs from their property. The only thing that’s effective is to humanly trap and release the wildlife further away. DIY groundhog control methods are proven to not be working most of the time. Thus, your best option is to hire an experienced wildlife control company.
