The most effective way to remove a groundhog is with a trap. The use of chemical or electronic repellents as well as the installation of a steel-mesh fence or other barrier can ensure that future infestations are less likely to occur.
When properly baited and deployed, a live groundhog trap can be very effective. Chemical sprays and granulated repellents can be used to keep groundhogs away from certain areas. Motion-activated water sprinklers are another way to keeping groundhogs away from flowerbeds, pathways and gardens.
Groundhogs are large ground-dwelling rodents that average about 10 pounds when fully grown. Groundhogs dig complex interconnecting burrows and may damage gardens and landscaping in their search for food.
