The most effective groundhog trap is a large wire cage trap placed directly at the entrance to the animal’s burrow. A standard groundhog-sized cage trap measures roughly 32 inches long by 10 inches wide by 12 inches tall, built from 12-gauge galvanized steel mesh with a spring-loaded door. Placement matters far more than bait, and most failed trapping attempts come down to putting the trap in the wrong spot.
Live Cage Traps vs. Body-Grip Traps
There are two main categories of groundhog traps: live cage traps and lethal body-grip traps. Each works differently and carries different risks.
Live cage traps are rectangular wire boxes with one or two spring-loaded doors. When the groundhog walks inside and steps on the trigger plate, the door snaps shut behind it. These are the most common choice for homeowners because they’re safe to set, reusable, and don’t risk injuring pets or children. A single-door model in the 32x10x12-inch range handles groundhogs well. Two-door models can increase catch rates because the animal sees light through both ends and feels less suspicious about entering.
Body-grip traps (sometimes called Conibear-style traps, after the most well-known brand) are lethal. They use powerful spring-loaded jaws that close around the animal’s body when triggered. The size 220 is the standard for groundhogs. These traps are typically set directly over a burrow entrance so the groundhog triggers them when exiting. They kill quickly, but they pose a serious danger to pets, children, and non-target wildlife. Setting them requires a dedicated trap-setting tool, and many states restrict their use to licensed trappers or require them to be placed inside enclosed sets. Unless you have experience with body-grip traps, a live cage trap is the safer and more practical option.
Where to Place Your Trap
The single biggest factor in catching a groundhog quickly is trap location. Forget placing a trap in the middle of your garden and hoping the groundhog wanders in. The most reliable method is setting the trap directly outside the entrance to the animal’s burrow, so it has no choice but to walk through it.
Once you’ve identified the active burrow entrance (look for a mound of freshly excavated dirt and worn paths in the grass), position the open end of the cage flush against the hole. Then build a simple funnel or barrier around the entrance using whatever you have nearby: rocks, firewood, crates, or scrap boards. The barrier doesn’t need to be tall or sturdy. Its only job is to block the groundhog from slipping around the sides of the trap, creating a path of least resistance that leads straight into the cage.
Set the trap in the evening after the groundhog has gone underground for the night. Groundhogs are diurnal, meaning they’re most active during the day and retreat to their burrows before dark. A trap set at dusk will likely have a groundhog in it by early morning.
If You Can’t Trap at the Burrow
Sometimes the burrow is under a deck, shed, or rock pile where you can’t easily position a trap. In that case, look for well-worn travel paths between the burrow and the groundhog’s feeding area, usually your garden. Place the trap along that route with natural vegetation or brush on both sides to guide the animal in. Cantaloupe, broccoli, and fresh pea pods work as bait in this scenario, though bait is far less reliable than burrow-entrance placement.
Handling a Trapped Groundhog Safely
A groundhog in a cage trap will be stressed and may lunge or bite if you stick your fingers near the wire. Approach the trap calmly. Draping an old towel or tarp over the cage helps settle the animal and protects you from contact. Groundhogs can carry fleas, ticks, and other parasites, though disease transmission to humans is uncommon. They generally avoid confrontation but will bite if cornered, so wear thick gloves and keep your hands away from the mesh.
Carry the trap by the handle on top, keeping it away from your body and at arm’s length. If you need to transport it in a vehicle, place it on a plastic sheet or tray since the animal will urinate and defecate inside the cage.
Legal Rules You Need to Know
Before you trap a groundhog, check your state’s wildlife regulations. The rules vary significantly and breaking them can result in fines.
In most states, groundhogs are classified as nuisance wildlife, and property owners are allowed to trap them when the animals are damaging property. However, what you can do after trapping is where the law gets strict. Many states prohibit relocating a trapped groundhog off your property. New York, for example, makes it illegal to live-trap an animal and release it in a park, on state land, or anywhere other than the property where it was captured. Michigan has a similar rule: groundhogs cannot be moved off the property where they were trapped. Violating relocation laws can spread diseases like rabies, introduce parasites to new areas, and cause severe stress to the animal.
If you can’t legally relocate the groundhog and don’t want to deal with dispatching it yourself, your best option is to contact a licensed nuisance wildlife control operator. These professionals have the permits and equipment to remove the animal legally. Your state’s fish and wildlife agency or department of natural resources can connect you with one in your area.
Preventing Groundhogs From Coming Back
Trapping solves the immediate problem, but an empty burrow and an unprotected garden will attract a new groundhog within weeks. After removing the animal, focus on exclusion.
For garden beds, the most reliable barrier is a fence made of 1-inch wire mesh buried at least 12 inches deep with the bottom 12 inches bent outward into an L-shape. This underground apron stops groundhogs from digging underneath. The fence above ground should stand at least 3 feet tall and, ideally, have the top 12 inches left unattached to any support post so it wobbles when a groundhog tries to climb over. This combination of a buried apron and floppy top has proven effective at keeping burrowing animals out for years.
For abandoned burrow entrances, fill them with a mix of dirt and gravel, then pack it tightly. Some people place hardware cloth over the filled hole and secure it with landscape staples. If the burrow is under a deck or shed, attach galvanized wire mesh along the base of the structure, extending it at least 12 inches underground with the same L-shaped footer to prevent re-entry.
