Understanding Risks, Signs, and Safe Removal
Our Ethical Approach to Wildlife
Respectful solutions for subterranean neighbors
At Advanced Wildlife Management, we understand that groundhogs play a role in the environment. That’s why we use humane, live-capture methods and ethical deterrence strategies to remove them safely. We take care to avoid harm to the animal while ensuring your home and property are properly protected from future invasions.
Understanding Groundhogs in Our Region
Burrowing wildlife that can undermine your foundation
Groundhogs—also known as woodchucks—are common across Wisconsin and Northern Illinois. These burrowing mammals are most active in warmer months and are often found near decks, sheds, patios, and garages. While they may seem harmless, their tunneling behavior can cause serious structural issues over time.

Warning Signs of Groundhogs
How to tell if a groundhog is your uninvited guest
- Large mounds of soil near decks or buildings
- Holes 8–12 inches in diameter at ground level
- Chewed garden plants or missing vegetables
- Sightings of a large rodent near daylight hours

Habitats and
Entry Points
Where groundhogs dig and how they impact
your property
- Under decks, sheds, porches, or garages
- Along concrete patios or retaining walls
- Near foundations or exposed crawlspaces
- Garden beds or loose soil near buildings
Their burrows can span 20+ feet and weaken the soil supporting important structures.
The Dangers of Groundhog Infestations
Unseen but serious structural and safety risks
Foundation Damage: Tunnels may cause erosion or instability under slabs
Tripping Hazards: Burrow entrances can collapse or trap pets
Landscape Destruction: Extensive digging and plant consumption
Secondary Pests: Vacated burrows may attract skunks, snakes, or other pests
Safe and Humane Groundhog Removal
