Groundhogs love to eat vegetables and flowers in the garden. They will also eat many types of crops including corn, soybeans, apples, and other fruit. They will dig under building foundations and weaken them. They can carry and transmit rabies and fleas.


Groundhogs can be trapped with foothold traps and cage-style traps. They can be shot with firearms. Installing wire mesh at least 6 inches below the ground along building foundations will help alleviate problems. Fencing around flowers and vegetables that goes at least 6 inches below ground is recommended.

For more information about groundhogs, check out the Pennsylvania Game Commission’s wildlife notes.

Special note concerning rabies vector (carrier) species. Rabies is a contagious, potentially fatal disease transmitted from one infected animal to another through a bite or scratch. Humans are susceptible to rabies and prompt medical attention is necessary. With this in mind, all rabies vector species trapped or removed by wildlife professionals must be humanely dispatched rather than relocated. Pennsylvania rabies vector species include skunks, raccoons, foxes, groundhogs, bats and coyotes.
