* Time of year: During the breeding season (typically February to April), a female groundhog may have a litter of 3 to 6 pups. These pups will stay with their mother for about 8 weeks before venturing out on their own.
* Burrow size and complexity: Larger, more complex burrows can accommodate multiple families.
* Food availability: When food is abundant, there may be more groundhogs in a burrow.
* Competition: In areas with high groundhog populations, there may be more competition for burrows, leading to smaller family groups.
Generally, a single family of groundhogs, including the mother and her young, will inhabit a burrow. However, it's possible for multiple families to share a larger, multi-chamber burrow.
Important Note: Groundhogs are considered pests in some areas due to their burrowing habits, which can damage gardens and lawns. If you find a groundhog burrow on your property, it's best to consult with a wildlife control professional for safe and humane removal options.
