1. How do I know if I have a groundhog problem on my property?

Groundhogs, also known as woodchucks, are burrowing animals that can cause significant damage to yards, gardens, and even building foundations. Some common signs of a groundhog infestation include large burrow openings near sheds, decks, or tree bases, mounds of dirt near holes, and chewed plants or garden vegetables. You may also see a groundhog during the daytime, as they are primarily active in the morning and early evening. If you notice tunnels near your home’s foundation, it’s important to address the issue quickly, as burrowing can weaken structures and lead to costly repairs.

2. Are groundhogs dangerous to humans and pets?

Groundhogs are not aggressive toward humans or pets, but they can become defensive if they feel threatened. If cornered, a groundhog may scratch or bite, which can transmit rabies or other diseases. Additionally, their burrowing habits can create unstable ground, which poses a risk of injury if a person or pet accidentally steps into a hole. While they don’t typically go after pets, they may act aggressively toward dogs or cats that invade their territory. The biggest concern with groundhogs is the structural damage they cause by digging under foundations, sidewalks, and patios.

3. What attracts groundhogs to my yard in Michigan?

Groundhogs are herbivores that feed on grasses, vegetables, flowers, and fruit, making gardens a prime food source. They are also attracted to properties with soft soil that makes burrowing easier. If your yard has tall grass, brush piles, or woodpiles, groundhogs may use these areas as cover while they dig their dens. They prefer locations near wooded areas, open fields, or bodies of water, which provide both food and protection. Keeping your yard well-maintained and eliminating potential food sources can help reduce the chances of a groundhog infestation.

4. How do professionals remove groundhogs from a property?

Wildlife control experts use humane and effective methods to safely remove groundhogs from properties. The most common method is live trapping, where baited traps are placed near burrow entrances to capture the groundhog safely. Some professionals use exclusion techniques, such as one-way doors that allow the groundhog to leave but prevent re-entry. Once the animal is removed, it’s essential to fill in burrows and reinforce structures to prevent another groundhog from taking its place. In some cases, habitat modification—such as installing fencing with buried barriers—is recommended to deter future infestations.

5. Is it legal to trap and relocate groundhogs in Michigan?

Yes, but Michigan has strict regulations regarding the trapping and relocation of groundhogs. According to the Michigan Department of Natural Resources (DNR), groundhogs can be trapped if they are causing damage, but they must be released within a one-mile radius of where they were captured. Relocating them to public lands or another person’s property without permission is illegal. Additionally, if a groundhog is trapped but not relocated properly, it may return or another animal may take its place. To comply with state laws, it’s best to hire a licensed wildlife control expert who can handle the removal legally and ethically.

6. How can I prevent groundhogs from burrowing under my shed or deck?

The best way to prevent groundhogs from burrowing under structures is to eliminate potential entry points and install exclusion barriers. Start by sealing openings with hardware cloth, steel mesh, or concrete and ensure that any fencing extends at least 12 inches underground to prevent digging. Removing potential attractants—such as overgrown vegetation, brush piles, and accessible food sources—will also discourage groundhogs from settling on your property. Motion-activated sprinklers, repellents, and even certain scents (such as predator urine) can help deter them. If groundhogs are already present, professional exclusion services may be necessary.

7. When are groundhogs most active in Michigan?

Groundhogs are most active during spring and summer when they are breeding, foraging, and preparing for hibernation. Breeding season occurs in early spring (March-April), with young groundhogs emerging from their burrows by late May or early June. During summer and early fall, groundhogs eat constantly to build up fat reserves for hibernation. In late October or November, they begin hibernating in underground burrows until early spring. Because they are less active in winter, the best time to address a groundhog problem is in spring or summer before they establish deep burrows.

8. How much does professional groundhog removal cost in Michigan?

The cost of professional groundhog removal varies depending on the severity of the infestation, the number of burrows, and the amount of damage repair needed. On average, groundhog removal services in Michigan range from $250 to $600. If exclusion barriers, habitat modification, or extensive repairs are required, the cost may be higher. Some wildlife control companies offer free inspections to assess the situation and provide a detailed estimate. Hiring a licensed wildlife removal specialist ensures the problem is handled legally, humanely, and effectively.
