Removing tall grass and other debris from property and closing woodchuck burrows are methods used to force woodchucks to relocate. It's necessary to remove debris before attempting to find burrows.
Woodchuck burrows may be hidden in wooded areas or adjoining properties, making it necessary to use other methods for removal. Fencing the property with a fine mesh or electric fence prevents woodchucks from coming onto the property from nearby spaces. Horticulture magazine states that bending the bottom edge of a fence 90 degrees, with the bent edge pointing away from the property, and burying the fence 4 inches stops woodchucks from digging into the property.
The Humane Society recommends fencing with mesh that is 3 inches by 3 inches, or smaller, or electric wire placed 4 inches above the ground. If mesh fencing is used, the fence should be at least 3 feet high and unsecured at the top 18 inches to prevent woodchucks from climbing over.
To eliminate burrows, clean away debris, such as high grass or piles of leaves, and use a shovel to partially close the burrow. The Humane Society recommends partially closing the burrow with loose soil, then placing used kitty litter inside the burrow. After it's clear that the woodchucks have moved, the burrow can be completely closed with soil. Disturbing burrows to get rid of woodchucks is most effective from June until September, according to the Humane Society.
