How Do I Catch a Woodchuck? What You Give Up Either Way

To catch a woodchuck, first confirm the burrow is active, then find out what state law permits you to do with the animal afterward, and only then set a live trap. University of Maryland Extension recommends a trap baited with fresh fruit or vegetables, left unset for several days so the animal treats it as a feeding station, placed near the burrow entrance just before daylight and removed before dark. Penn State Extension puts the minimum trap size at 10 by 10 by 24 inches and lists apple slices, carrots with tops, cantaloupe, lettuce and cabbage as bait. Trapping removes one animal. It does not remove the burrow, and several states allow release only on the property the animal came from.

That last clause is where most backyard trapping plans fall apart. The real choice is between catching the animal and fencing the garden, and each costs something the other does not.

Confirm a woodchuck is using the burrow, not something else

The main entrance is the giveaway. Penn State Extension's woodchuck fact sheet describes an entranceway 10 to 12 inches in diameter that "goes down at a rather steep angle and then levels off into a narrower tunnel," marked by a mound of excavated soil the animal sits on to watch for danger. Judy Loven of USDA-APHIS-Wildlife Services, author of Purdue Extension's woodchuck bulletin, gives the test for a borrowed burrow: "When other animals such as rabbits, skunks, foxes, or badgers are using woodchuck burrows, the fresh earth mound is absent at the entrance."

One entrance is never the whole burrow. Connecticut's Department of Energy and Environmental Protection reports most burrows run 25 to 30 feet long and 2 to 5 feet deep, with at least two entrances. Purdue Extension puts the system 2 to 4 feet down and 15 to 25 feet horizontally; Maryland Extension gives the widest range, 8 to 66 feet. The sources do not reconcile the spread; depth and length track soil type and the burrow's age. The secondary holes matter more than the numbers: plunge holes are dug from below, hidden in vegetation, and carry no mound.

Humane World for Animals gives a slower activity test than most homeowner pages: "Loosely plug all the burrow entrances (there may be several) with grass clippings or newspaper and monitor activity. If the material has not been disturbed after three to five days in clear summer weather, you can assume the burrow is unoccupied." Pest-control sites commonly cite 24 hours. The longer window is safer: a woodchuck that has not moved for a day has told you nothing.

Check the release rules before the trap comes out of the box

The law decides whether trapping solves anything at all.

Maryland Extension states that no permit is required to trap a groundhog, but that "permission is required from the landowner before releasing into suitable habitat." It advises against relocation in spring while young are in the den, or in autumn just before hibernation. The same page lists the state Nuisance Wildlife Information Line, 1-877-463-6497, which settles the rules before money goes on a trap.

Pennsylvania is stricter, for a specific reason. Margaret C. Brittingham, a Penn State professor of wildlife resources and an author of the university's extension fact sheet on woodchucks, writes with her co-authors: "Since woodchucks are considered a potential rabies vector, the Game Commission does not allow them to be relocated to other properties." A trapped animal must be euthanized or released elsewhere on the same landowner's property. New Jersey's Division of Fish and Wildlife also lists woodchucks as a rabies vector species, and MassWildlife treats relocating wildlife off your property as illegal statewide.

The animal's range decides what that means. Penn State puts foraging at 50 to 150 feet from the den and Maryland Extension says a groundhog usually travels no more than 150 feet to feed, while Loven's Purdue bulletin splits the figure by habitat: 20 to 30 yards in a soybean field, but several hundred yards daily in woodlots, road edges and yards, which is the suburban case. Under the Pennsylvania rule, a release on the same half-acre puts the animal back inside its own foraging radius, in sight of the garden it came from.

Set the trap so it catches the right animal

Timing does most of the non-target work. Woodchucks are diurnal and sit out the night underground, which is why Maryland Extension puts the trap out just before daylight and takes it in before dark. A trap left standing overnight is a fruit-and-vegetable buffet for skunks, opossums, raccoons and cats, all active while the woodchuck sleeps.

The rest is placement. Penn State recommends setting at the burrow entrance, in a travel lane, or at the site of damage, with guide logs on either side and a dark canvas or grass cover. It instructs owners to "check all traps twice daily, morning and evening, so that captured animals may be quickly removed"; Connecticut DEEP asks for several checks a day in summer heat, when a caged animal in sun can die of exposure.

The question that gets skipped: what happens to the animal in the box

In Pennsylvania and Massachusetts, off-site release is not available, leaving euthanasia or a licensed wildlife control operator at the homeowner's cost. Maryland allows release, but only with a named person's permission on receiving land, and its seasonal advice rules out much of spring and autumn. Anyone unwilling to make that call at six in the morning, with a live animal in a cage, should make it before buying the trap.

Trapping versus garden exclusion, and what each one gives up

Live trapping is fast, cheap up front, and removes the animal eating the beans. What it gives up is permanence and the disposal decision. It leaves an intact burrow that broadcasts vacancy, and Penn State records a single annual litter of two to six young, usually four, weaned by late June or early July before they "strike out on their own"; Ohio's Department of Natural Resources reports 2 to 7, averaging 4 to 5. Those dispersing juveniles are looking for exactly the burrow you just emptied.

Exclusion gives up a weekend and the flowerbed's appearance. A trench has to be dug around the whole perimeter, and the fence maintained, since vegetation touching an electrified strand shorts it out. What it buys is a barrier that does not care which woodchuck arrives, needs nobody's permission, and puts no live animal in the owner's hands at dawn. In a yard bordered by field edge or brush, exclusion survives the second and third animal; trapping handles one quickly. Extension sources treat them as complements: exclusion first, trapping second for whatever is already inside.

Published fence specifications vary more than any single page suggests:

| Source | Height above ground | Buried depth | Electric wire | |---|---|---|---| | University of Maryland Extension | 4 ft | 12 in | 4–5 in above ground, 4–5 in outside the fence | | Penn State Extension | at least 3 ft | 12 in, lower 6 in bent outward in an L | 4–5 in above ground, same distance outside | | Connecticut DEEP | at least 3 ft | 1.5–2 ft | 4–6 in above ground and/or at the top | | Humane World for Animals | 3-ft welded wire sections | at least 1 ft | single strand 4 in up, 6 in in front of the fence |

Burial depth is where they genuinely diverge: Connecticut asks for roughly double what Maryland does. Soil decides it, and in loose loam the deeper figure earns its digging.

Yard features that make trapping fail

A garden in full production is a competing bait station. Cantaloupe in a cage is a weak offer next to twenty feet of unfenced chard, which is why late-season trapping beats midsummer.

Multiple hidden entrances mean the trap at the obvious mound may sit on a door the animal stopped using. Neighboring yards inside a 150-foot radius supply replacements whatever happens on your lot. Resident cats and opossums raise the odds that the first capture is not a woodchuck. And a burrow under a shed or deck often has no trappable entrance in the open at all.

The burrow is already under the shed

Do not seal it on the assumption it is empty. Humane World for Animals reports that breeding females have dependent young in the burrow from late winter until spring or early summer, and names the safe eviction window as mid- to late summer, between early July and late September. Sealing before that walls in a litter.

The timing is contested. Loven's Purdue bulletin, written for crop fields, puts control in early spring "when active burrows are easy to find, the young woodchucks have not yet scattered." Humane World calls those same weeks the wrong ones for evicting an animal from under a structure. They answer different questions; a homeowner standing over a shed skirt is asking Humane World's.

The sequence is the plug test on every opening, three to five days of clear weather, then the barrier. Humane World specifies heavy-gauge welded fencing wire with squares no larger than 3 inches, in 3-by-3-foot sections, buried at least a foot deep and pinned with landscape staples. The L-shaped outward bend Penn State prescribes for garden fence applies at a shed skirt too; the bend, not the depth, stops a digger from following the wire down.

Short of construction, Humane World lists digging out the entrances, clearing cover, and placing urine-saturated cat litter or a capsaicin repellent inside them. None of that touches the tunnel.

Habitat changes that lower the pressure next season

Woodchucks den where cover meets food. Clearing brush piles, rock piles and scrap lumber inside the foraging radius removes the staging cover; mowing field edges removes the travel lane. Old burrows get reoccupied for years, so collapsing and backfilling an abandoned one is part of the work. Penn State dates hibernation from late October into March, which makes late autumn the practical window for trenching, with nothing underground to evict.

FAQ

Is it legal to shoot a groundhog in your backyard?

Rarely in a suburb, whatever state hunting law allows. Pennsylvania classifies the woodchuck as a game species requiring a hunting license, with a 2026-27 season closed only on Christmas Day. Yet 34 Pa.C.S. § 2505 bars hunting within 150 yards of an occupied building without the occupants' permission, and municipal discharge ordinances usually prohibit it outright.

What gets rid of groundhogs fast?

Nothing that also keeps them gone. A live trap pre-baited for several days and set at the burrow entrance at dawn is the quickest removal of one animal, per University of Maryland Extension. Because a vacant burrow attracts dispersing juveniles in July, fast removal without a buried fence usually means repeating the exercise within the same season.

What bait is irresistible to groundhogs?

There is no irresistible bait, only bait that beats what the yard already offers. University of Maryland Extension specifies fresh fruit or vegetables. Penn State Extension lists apple slices, carrots with tops, cantaloupe pieces, lettuce, cabbage and fresh peas. In a garden mid-harvest, none of those outbids the row of chard behind them.

What is the best bait for a woodchuck trap?

Penn State Extension's trapping guidance names cantaloupe pieces, apple slices and carrots with tops as primary choices, replaced daily with wilted pieces removed. Bait alone is not the variable that decides success: the same fruit draws skunks, opossums and raccoons, so pulling the trap before dark matters as much as what is inside it.

Can a woodchuck be caught without a trap?

Not safely or legally in most cases. Woodchucks are a rabies vector species in the mid-Atlantic, so hand capture is a bite risk with a public health consequence. The practical no-trap options are exclusion and eviction: a buried L-footer fence, a plug test to confirm vacancy, and harassment at the burrow entrance during the July-to-September window.

How do I confirm that a burrow is active before exclusion?

Humane World for Animals advises loosely plugging every entrance with grass clippings or newspaper and watching it. If the material is undisturbed after three to five days of clear summer weather, the burrow can be treated as unoccupied. Find the hidden plunge holes first, since they lack the soil mound that marks the main entrance.
