How to Deter Woodchucks (Groundhogs) From Your Garden

The best way to stop woodchucks is to make your yard less appealing than nearby habitat. Many states prohibit trapping and relocating them, so focus on exclusion and repellents.

Repellents: Beach balls that move in the wind can annoy woodchucks. Ammonia-soaked rags stuffed into burrow entrances (main hole has a soil mound; secondary entrance is ~50 feet away) may drive them out. Fox urine, sold at garden centers, creates a predator scent barrier when applied around the garden perimeter.

Fencing (permanent solution): Install chicken wire fence at least 3 feet high, buried 12 inches deep. Leave the top 12-18 inches unattached to posts so it bends outward if climbed. For heavy pressure, add an electric wire 4 inches off the ground.

Resistant plants: Woodchucks tend to avoid columbine, daylily, blanket flower, cardinal flower, and marigold.

Dog: A dog that chases woodchucks can be an effective deterrent.
