🦫 Groundhog Removal in Brentwood

Groundhogs in Brentwood, Tennessee

Groundhogs (Marmota monax — also called woodchucks) are not the highest-volume call species in the Brentwood market, but the calls that do come in tend to be high-stakes: burrows undermining a deck footing, a shed corner, a barn, or — worst case — a foundation. The dominant Brentwood groundhog territory is the rural-edge equestrian properties on McGavock Pike, the wooded margins of Holly Tree Gap and Wikle Road, and the larger acreage along the city's southern boundary. They are active March through October, hibernate November through February, and a single mature groundhog can dig a burrow system with multiple entrances spanning 20-50 feet under a single structure.

Where Groundhogs Are a Real Problem in Brentwood

The Brentwood groundhog map is not the same as the raccoon, squirrel, or bat map. Groundhogs are field-edge mammals — they prefer the transitions between open lawn or pasture and adjacent woods, where they can graze in the open and retreat to burrows along the wooded edge. The neighborhoods that generate the most groundhog calls in Brentwood:

• McGavock Pike and the rural-edge equestrian properties. Larger acreage with pasture-to-woods transitions, barn outbuildings, and tack-room structures that groundhogs burrow under.
• Holly Tree Gap and Wikle Road area. Wooded foothill estates with sloped lots, retaining walls, and sheds that create classic groundhog burrow sites.
• Larger McGavock Farms and Carondelet lots backing onto retained tree buffers — the wooded edges support burrow sites that then extend toward decks and foundations.
• Crockett Park-adjacent properties. Homes within a quarter mile of the park boundary see significantly more groundhog activity than the rest of the city.

Calls from the densely-built core neighborhoods — Brenthaven, Brentwood Hills, the Concord Road corridor — are uncommon. Groundhogs need contiguous open ground for foraging, and the dense suburban core doesn't provide it.

How a Groundhog Burrow Damages a Brentwood Foundation

A mature groundhog excavates a burrow system that's typically 4 to 6 feet deep, 20 to 50 feet long, and includes 2 to 5 entrance holes. When that excavation runs under a deck footing, a shed corner, a barn slab, or — in the worst Brentwood cases — a residential foundation, three failure modes follow:

1. Footing settlement. Deck and shed footings designed for undisturbed soil settle into the void, producing visible structural movement: doors that won't close, decks that tilt, and sheds that pull away from siding.
2. Foundation undercutting. On rare but serious cases — typically older detached structures rather than primary residences — the burrow undermines the foundation footing edge and produces cracking or partial settlement.
3. Concentrated water intrusion. Burrow entrances become drainage channels during heavy rain, redirecting surface water against foundations and into crawlspaces in ways that the original grading never anticipated.

The repair cost on each of these is typically 10-50 times the cost of the original groundhog removal, which is why early intervention matters.

Why Groundhogs Like Brentwood's Equestrian Properties

The McGavock Pike equestrian properties combine all the features groundhogs prefer: sustained pasture for grazing, well-drained soil that's easy to excavate, abundant cover under barns, tack rooms, and feed-storage structures, and the absence of the suburban human disturbance that pushes them out of denser neighborhoods. Pasture-edge groundhog populations on Brentwood horse properties commonly run three to five established burrow systems per ten acres, and a single property may need multiple removals over a season to fully clear the population.

Groundhog Trapping in Brentwood: TWRA Rules

Groundhogs in Tennessee are managed under TWRA nuisance-wildlife rules. Live trapping with cage traps is the standard removal method on Brentwood properties — bait is typically apple or cantaloupe placed in a baffle-cage trap positioned at the active burrow entrance. Relocation off the property of capture is restricted under TWRA rules, and the licensed contractor handles disposition according to state regulations. After the burrow system is cleared of animals, the entrances are filled with crushed stone capped with concrete or with a one-way burrow-exclusion device to prevent re-occupancy by a new groundhog. The licensed contractor handles trapping, exclusion, and TWRA-compliant disposition end-to-end.

Repair After a Brentwood Groundhog Eviction

The standard repair scope on a serious Brentwood groundhog job:

• Burrow filling with crushed stone and compacted backfill, or — when the burrow runs under a structure — fully sealed with a one-way exclusion device first, then filled.
• Foundation and footing assessment by the contractor or, on serious settlement cases, a licensed structural engineer.
• Drainage correction where burrow entrances have redirected surface water — re-grading, French drain installation, or downspout extension as needed.
• Perimeter exclusion on decks and sheds — galvanized hardware-cloth skirting buried 12 inches deep prevents future burrow attempts.

⚠️ Peak Burrowing Season

Groundhogs are at maximum activity — feeding, expanding burrows, and raising young. Foundation and structural damage accelerates during this period. A single burrow can undermine a deck footing or concrete slab within one season.
