How To Get Rid Of Groundhogs Under House

Is the sound of scratching and scurrying under your house keeping you up at night? You're not alone. Groundhogs, also known as woodchucks, are notorious for their digging habits and can cause significant damage when they decide to set up shop beneath your home. Their burrows can undermine foundations, damage utility lines, and create unsightly mounds in your yard. Beyond the structural concerns, their presence can also pose health risks through potential disease transmission to pets and even humans.

Dealing with a groundhog under your house requires a strategic and humane approach. Ignoring the problem can lead to escalating damage and a larger, more established burrow system. Taking swift action is crucial to protecting your property and preventing further headaches. There are various methods you can employ, from preventative measures to humane removal techniques, but knowing which strategy is right for your situation is key.

How do I identify groundhog entry points under my house?

To find where groundhogs are getting under your house, carefully inspect the perimeter of your foundation, paying close attention to areas with loose soil, overgrown vegetation, or existing holes. Look for freshly dug soil, groundhog tracks (small, five-toed prints), worn paths leading to holes, and any damage to siding or foundation vents.

Groundhogs typically dig their burrows near structures that offer cover and protection, so focus your search around decks, porches, sheds, and any low-lying areas adjacent to your house. Probe any suspicious-looking holes with a stick to determine their depth and direction. Groundhog burrows usually have multiple entrances and can extend quite far underground, so you might find more than one entry point. Remember to look for secondary entrances that may be less obvious than the main one. Finally, consider the height of the opening. Groundhogs are relatively large animals. Any hole smaller than 6-8 inches in diameter is unlikely to be a groundhog entrance. Also, keep in mind that other animals might be using groundhog burrows, so confirming groundhog activity (sightings, droppings) near the identified entry point is important before taking any removal action.

What are humane methods for removing groundhogs from under my house?

The most effective and humane method for removing groundhogs from under your house involves a combination of habitat modification, exclusion, and, if necessary, live trapping and relocation. The goal is to encourage the groundhog to leave on its own without causing it harm, and then prevent it from returning.

Firstly, make your property less attractive to groundhogs. This involves removing potential food sources like fallen fruits, berries, and accessible garden vegetables. Clear away brush piles, woodpiles, and any other debris that could provide shelter. Consider using deterrents like motion-activated sprinklers or noisemakers near the burrow entrance. A strong-smelling repellent containing castor oil can also be applied around the burrow entrance to encourage the groundhog to leave. These methods create an unpleasant environment, prompting the animal to seek a more suitable habitat. Once the groundhog has hopefully relocated, the most important step is to prevent its return by excluding it from under your house. This involves carefully sealing all potential entry points. This includes patching holes in the foundation, installing sturdy wire mesh fencing (at least 12 inches deep) around the perimeter of your house, and ensuring any existing vents or openings are covered with heavy-duty hardware cloth. Make sure the wire mesh extends outward from the foundation at least 12 inches to prevent digging underneath. In situations where the groundhog is particularly persistent or these methods are ineffective, live trapping and relocation may be necessary. Use a humane trap baited with cantaloupe, apples, or other fruits placed near the burrow entrance. Check the trap frequently, ideally twice a day, and release the groundhog in a suitable relocation area that is at least 5-10 miles away from your property, ideally with wooded areas, meadows, and a water source. Contact your local animal control or wildlife authorities for specific regulations regarding trapping and relocation, as these vary by location. Note that some areas prohibit relocation entirely, so familiarize yourself with local ordinances before attempting to trap.

Can deterrents like noise or smells effectively get rid of groundhogs?

While noise and smells can sometimes act as temporary deterrents for groundhogs, they are generally not effective as long-term solutions, especially when groundhogs are already established under a house. Groundhogs are persistent creatures, and if they perceive the area under your house as a safe and resource-rich environment (providing shelter and potentially easy access to food sources), they are unlikely to be deterred for long by simple noises or odors.

The problem with relying solely on noise or smells is habituation. Groundhogs can become accustomed to consistent noises, rendering them ineffective. Similarly, smells, even strong ones, dissipate over time, requiring constant reapplication. Furthermore, if a female groundhog has established a den with young under your house, her maternal instincts will override any aversion to these deterrents. She'll prioritize the safety and well-being of her offspring above all else. To effectively remove groundhogs from under your house, a more comprehensive approach is needed. This often involves a combination of methods, including exclusion techniques (like installing a one-way exclusion door after verifying the groundhog is out), habitat modification (removing potential food sources and cover near the house), and, in some cases, professional wildlife removal services. Employing persistent deterrents alongside exclusion methods can increase the likelihood of success.

How do I repair the damage caused by groundhogs under my house?

Repairing groundhog damage under your house is crucial to prevent structural issues and further infestations. The process generally involves removing the groundhogs, thoroughly inspecting the area, repairing any damaged foundations, support beams, pipes, or wiring, and implementing preventative measures to deter future burrowing.

Begin by ensuring the groundhogs are completely gone. (Refer to previously answered question for groundhog removal). Once you're certain they've left, carefully inspect the entire area under your house. Look for signs of structural damage, such as cracks in the foundation, weakened support beams, damaged insulation, or compromised plumbing and electrical lines. Document the damage with photos and videos, as this may be useful for insurance claims or professional consultations. Small holes can often be filled with tightly packed gravel and then covered with cement. More significant structural damage, however, might necessitate the assistance of a qualified contractor experienced in foundation repair.

After the repairs are complete, focus on preventing re-infestation. This involves blocking access to the under-house area. The most effective method is to install a sturdy wire mesh barrier that extends at least 12 inches below the ground and at least 2 feet above. Ensure the mesh is securely fastened to the foundation and that there are no gaps where groundhogs can dig under or squeeze through. Consider burying the bottom edge of the mesh in an L-shape, pointing outward, to further deter digging. Regularly inspect the barrier for any signs of damage and promptly repair any breaches. You may also consider using deterrents around the perimeter of your house, such as motion-activated sprinklers or ultrasonic pest repellers, to make the area less attractive to groundhogs in the future.

What are the risks of leaving groundhogs under my house?

Leaving groundhogs under your house poses several risks, including structural damage to the foundation and supports due to their burrowing, potential electrical wiring damage if they chew on it, creating unpleasant odors from their droppings, and the risk of introducing fleas, ticks, and other parasites into your home. Groundhogs can also attract larger predators and might become aggressive if they feel threatened, potentially endangering pets or even people.

Groundhogs are prolific diggers, and their burrowing activity can compromise the structural integrity of your foundation. Their tunnels can undermine concrete slabs, weaken support beams, and even cause sinkholes to form around your house. These issues are very expensive to repair. Over time, unchecked groundhog activity could significantly destabilize your home's foundation. Furthermore, groundhogs are rodents and have a natural tendency to gnaw. They may chew on electrical wiring, plumbing, or insulation materials while exploring the under-house area. Damaged wiring can create a fire hazard, while damaged plumbing can lead to leaks and water damage. The accumulation of groundhog droppings under your house can also create unpleasant odors that permeate into your living spaces. These droppings can also harbor harmful bacteria and pathogens, posing a health risk to your family and pets. Finally, groundhogs are hosts to various parasites, such as fleas, ticks, and mites. These parasites can easily migrate into your home, infesting carpets, furniture, and even your pets. Groundhogs may also attract larger predators, such as foxes or coyotes, to your property, potentially posing a threat to your pets or small children. While generally not aggressive, groundhogs will defend themselves if cornered or feel threatened, and their bites can transmit diseases.

How do I prevent groundhogs from returning after removal?

The key to preventing groundhogs from returning after removal is to eliminate what attracted them in the first place and physically block access to their former denning areas. This involves removing food sources, modifying your landscaping to make it less appealing, and implementing exclusion methods to prevent them from re-entering under your house.

To make your property less inviting to groundhogs, focus on reducing available food and shelter. Remove fallen fruits, vegetables, and seeds from your yard regularly. Consider fencing off vegetable gardens or other vulnerable plants with wire mesh that extends both above and below ground. Mow your lawn frequently to eliminate tall grasses they can use for cover. Remove woodpiles, brush piles, and other debris that provide potential hiding places. If you have bird feeders, clean up spilled seed regularly and consider using squirrel-proof feeders, as groundhogs will readily consume spilled birdseed. Once the groundhog is removed (either humanely trapped and relocated by a professional, or through natural departure), immediately focus on exclusion. Thoroughly inspect the area under your house to identify all entry points. These can be cracks in the foundation, gaps around pipes, or weakened areas in the siding. Seal these openings with durable materials such as heavy-gauge wire mesh (hardware cloth), concrete, or sheet metal. For underground openings, bury the wire mesh at least 12 inches deep with an outward-facing "L" shape to prevent digging. Continuously monitor the area for any signs of new digging or entry attempts and repair any breaches promptly. Persistent vigilance is necessary as groundhogs are determined animals and will often try to find weaknesses in your defenses.

Should I hire a professional to remove groundhogs, or can I do it myself?

Dealing with groundhogs under your house is a serious issue that often warrants professional intervention. While DIY methods might seem appealing, they can be ineffective, inhumane, and even dangerous, especially when dealing with animals that may be trapped or feel threatened. A professional wildlife removal service possesses the expertise, tools, and knowledge to safely and humanely remove the groundhogs and prevent future infestations.

The primary reason to consider a professional is the complexity of the situation. Groundhogs burrow deep and create elaborate tunnel systems, often with multiple entry and exit points. Identifying all these points and effectively sealing them after removal is crucial to prevent re-entry. Professionals are trained to assess the extent of the infestation, identify vulnerable areas of your home's foundation, and implement a comprehensive removal and prevention strategy. Attempting to block entry points yourself without proper knowledge can trap the animal inside, leading to its demise and creating unpleasant odors and potential health hazards. Furthermore, groundhogs can carry diseases and parasites, posing a risk to you and your family if handled improperly. Professionals use protective equipment and follow established protocols to minimize these risks.

Another key aspect is humane treatment. Many DIY removal methods involve trapping, which, if not done correctly, can cause the groundhog significant stress and injury. Some traps are even illegal in certain areas due to their inhumane nature. A professional will employ humane trapping techniques or, where appropriate, employ exclusion methods that encourage the groundhog to leave on its own without causing harm. They also understand local wildlife regulations and ensure that the removal process is compliant with the law. Ultimately, while attempting DIY groundhog removal might seem cost-effective, the risks and potential complications often outweigh the perceived benefits. Engaging a professional is the safest, most effective, and most humane way to resolve a groundhog infestation under your house.
