Generally, groundhogs, also referred to as woodchucks, are considered large rodents. Comparable to other species in the rodent family, the groundhogs will dig holes to create burrows and to dig for grubs, which constitute a large part of a groundhog's diet.

Keeping groundhogs out of your garden via natural methods is a great way to stop them from ruining your landscaping and gardens.

Castor Oil

Groundhogs detest the scent of castor oil. Only sprinkle the burrow hole with castor oil after the groundhogs have exited the hole. Otherwise, they will dig themselves a different hole to exit the burrow in order to avoid contact with the oil. 


Groundhogs are startled by noise; that's one reason why adding chimes to the perimeter of your garden will help keep the groundhogs from tunneling beneath the topsoil. However, the main drawback to using this method is that when the winds are still, there are no active deterrents to keep the groundhogs away. 

Epsom Salt

Sprinkle Epsom salt around the entrances and exits of the burrows, or pour the salt into a small bowl and set it next to the burrow entrance. Be sure to refill after each rain because the water will dissolve the Epsom salt quickly. 

Human Hair

Sprinkle human hair around the burrows, or, if you have enough hair, place it around the perimeter of the garden to prevent groundhogs from burrowing. The presence of human hair will also deter other pests like deer, rabbits, and mice.

Pro tip: wrap human hair around a small stick or twig and stick it in the earth to keep it in place through wind and rain. Otherwise, the hair will blow or wash away if it isn't secured. 

Soiled Cat Litter

Pour soiled cat litter near the opening of one of the burrow holes (but not both) because the scent of a predator at the entrance and exit will cause the groundhogs to dig another hole. 

Although this is a proven method to deter groundhogs and other rodents, please beware that using soiled cat litter in a garden is not encouraged because of the presence of the protozoan parasite toxoplasma gondii in cat feces.

Toxoplasma will add bacteria to the garden, which is harmful to animals and humans in the surrounding environments.

Word of caution: if you or someone in your home is pregnant or may be pregnant, do not change or clean the litter boxes in order to avoid contact with toxoplasma in cat feces, which are toxic to pregnant people. 

Rodent Repellents 

Implementing a rodent repellent is a good option for deterring groundhogs around outer buildings. It's easy to use; simply follow the instructions on the bottle and reapply as needed.
