Groundhog removal inPenn Yan, NY

That is why groundhog work begins with reading the property rather than the single opening a homeowner noticed. The visible entrance is often the least important part: the tunnel may run under a deck footing, along a shed skid, beside a foundation wall or beneath a walkway, and the excavated soil has to come from somewhere.

It is also why the outcome is measured structurally. Over time, undermining shows up as a settling slab, a shifting shed, a leaning deck post, an eroding bank or a hollow spot in a lawn that gives underfoot.

Overhead cover

A deck, shed or slab is a ready-made roof over a burrow that would otherwise be exposed.

Workable soil

Loose, drained backfill around structures and along grade changes is easier to excavate than compacted ground.

Reliable forage

Lawns, gardens and field edges provide the vegetation that supports a resident animal.

Seasonal cycle

Groundhogs are true hibernators, so burrow use is heaviest through the active season and around emergence.

Low disturbance

Quiet edges of a yard — behind a shed, under a rear deck — see very little foot traffic.

An existing burrow

Vacant systems are attractive to the next animal, including other species that will use them.

How do I know the hole in my yard is a groundhog burrow?

Groundhog entrances are typically large — roughly eight to twelve inches — and the main opening usually has a visible fan of excavated soil. Secondary exits are cleaner and set away from the main hole. Location matters too: burrows tend to sit at cover such as a deck edge, shed corner, bank or fence line.

How deep and how far do the tunnels go?

A burrow system is considerably larger than the visible opening suggests, with connecting tunnels, more than one exit and separate chambers. That is why the inspection looks at what the system runs beneath rather than just the entrance.

Can a groundhog damage my foundation or deck?

Excavation removes soil that structures rely on for support. Over time that can show as a settling slab, a shifting shed, a moving deck post, a cracked walkway or an eroding bank. The severity depends on how much soil has been moved and what is above it.

Will filling the hole solve it?

Rarely on its own. A resident animal typically reopens a filled entrance or uses a secondary one, and filling an occupied burrow raises its own problems. The activity has to be understood and resolved before ground work is meaningful.

Do groundhogs get inside houses?

Not usually. They are ground dwellers and the concern is what happens beneath a structure rather than inside it. The exception is space they open beneath a shed, deck or crawlspace edge that then becomes accessible to other species.

Do groundhogs hibernate, and does that end the problem?

Groundhogs are true hibernators, so surface activity drops sharply in the cold months. The burrow system remains, however, and the undermining it has already caused does not reverse over winter.

Something else moved into the old burrow — is that normal?

Yes. Vacant groundhog burrows are readily used by skunks, opossums and other wildlife. An unaddressed burrow system tends to keep producing calls even after the original animal is gone.

Can I keep them out with fencing?

Barrier work can be part of a solution in the right situation, but it has to account for digging and for how the specific structure is built. Whether it is worthwhile on a given property is a judgment made from the site, not a general recommendation.

They are eating my garden — is that the same job?

Feeding is the reason the animal stays; the burrow is what damages the property. Both are part of the same picture, and both are worth describing when you get in touch.
