You might get anxious when you notice a groundhog climbing a fence or tree in your yard. Groundhogs, also known as woodchucks, are herbivores that typically stay on the ground but are capable climbers when necessary.
They may be searching for food—grass, fruits, vegetables, or tree bark—or climbing to escape predators. Unfortunately, once in your yard, groundhogs can cause costly damage to gardens, lawns, fences, irrigation systems, and even house foundations.
Yes. Despite their plump, stocky bodies, groundhogs are agile climbers thanks to their strong claws. These claws are designed for digging but also allow them to climb poles, fences, and even tree branches. They may climb to:
Groundhogs are accomplished tree climbers and can often be found perched 10 feet high, eating leaves. They can also climb over most fences and will tunnel under them if needed. A fence that isn’t reinforced or tall enough won’t stop them.
Because groundhogs are skilled diggers and climbers, you need a strong, well-planned fence:
Chicken wire (hex netting) can be used to deter groundhogs, but it must be tall (5 feet), buried 1 foot underground, and reinforced at the top. Without reinforcement, groundhogs may climb it like a ladder.
Welded wire, such as hardware cloth, is stronger and more durable than chicken wire. It’s chew-proof and long-lasting, making it a better choice for keeping groundhogs out.
Electric fencing can effectively repel groundhogs with a mild shock. A low voltage strand 4 inches above the ground—or an additional strand at 9 inches—can discourage entry. Check local regulations before installing one.
Groundhogs are persistent and destructive. They dig, climb, and forage relentlessly, making them tough to keep out of yards. The most effective prevention method is fencing—installed deep, tall, and reinforced to prevent both digging and climbing. If you already have groundhogs in your yard, professional wildlife control may be necessary.
