How can you tell a groundhog burrow?
Measure the hole. Woodchuck burrows will have a large opening about 10 to 12 inches across, with a raised mound of dirt just outside. This mound is one of the most obvious signs of a woodchuck burrow. Often there will be one to three additional escape openings without the mounds, which are usually camouflaged.
Where does the dirt go when a groundhog dig a hole?
The groundhog is a very clean animal and will deposit all its waste in this latrine area. After the latrine is full, the area is sealed off and another latrine area is dug. At times, the groundhog will remove the dried excrement and bury it outside the burrow.
