What top-edge modification helps prevent a woodchuck from climbing over a fence?

• A. Bend the top 15 inches outward at a 45-degree angle
• B. Bend the top inward
• C. Add a cap
• D. Attach barbed wire

Answer: (A)

Creating an overhang at the top of the fence stops a woodchuck by removing the foothold it uses to pull itself over. Bending the top outward about 15 inches at a 45-degree angle tilts the edge away from the yard, forming a downward-facing lip that prevents claws from getting a solid grip and makes it difficult to push the body over the edge. The 15-inch extension ensures the overhang is long enough to stop leverage from the animal’s hind legs, while the 45-degree angle provides a true overhang rather than a flat top. Bending inward wouldn’t stop a climber as effectively because the lip could still present a grab point from outside or fail to shed the animal’s weight. Adding a cap might reduce grip a bit but usually doesn’t create a sufficient overhang to prevent climbing. Barbed wire can deter some animals but is hazardous and not a humane or reliable exclusion method. So, the outward bend with a substantial overhang is the best way to create a nonlethal, maintenance-light barrier that woodchucks can’t easily climb.
