Getting Rid of Raccoons Under Deck: Humane Solutions & Prevention Tips

Discovering raccoons under your deck can be a stressful experience. These intelligent and dexterous animals seek out the dark, enclosed space for shelter, especially as the weather cools. Left unaddressed, they can create a significant mess, damage structural elements, and pose health risks to you and your pets. Effectively getting rid of raccoons under deck structures requires a strategic approach that prioritizes humane eviction and long-term exclusion over simple, temporary deterrents.

The first step in solving this problem is confirming the identity of your unwelcome guest and assessing the severity of the intrusion. Raccoons are nocturnal, so you might hear heavy footfalls, rustling, or vocalizations like growls or screams during the night. Look for physical signs such as distinct paw prints, scattered food waste like crab shells or cat food, and small, cylindrical droppings. It is crucial to verify that the animal is not a protected species or a mother with babies before taking any action, as this dictates the legal and ethical methods available for removal.

Understanding Raccoon Behavior and Motivation

Raccoons are highly adaptable creatures, and the space beneath a deck offers an ideal refuge. It protects them from predators and harsh weather while providing a stable temperature year-round. They are primarily motivated by food and shelter, and if your property offers easy access to pet food, unsecured garbage, or garden pests, the location becomes even more attractive. Understanding that they are not inherently aggressive but will defend themselves or their young if cornered is key to developing a safe and effective removal strategy.

Assessing the Damage and Entry Points

Before you can evict the raccoons, you must determine how they are gaining access. Inspect the perimeter of your deck foundation carefully, looking for gaps along the siding, holes chewed through vents or lattice, or lifted boards. Raccoons can squeeze through surprisingly small openings, roughly the size of a baseball. Documenting these entry points is critical, as you will need to seal them all after the animals have been removed to prevent re-entry. Ignoring this step guarantees that the problem will return.

Humane Removal Strategies

The most effective and ethical method for getting rid of raccoons under deck is to encourage them to leave and not return. The goal is to make the space beneath your deck temporarily uninhabitable, prompting the animals to seek shelter elsewhere. This is usually done using a one-way door or exclusion device installed over the main entry point. The mechanism allows the raccoon to exit safely but blocks its return, ensuring a humane resolution without the need for trapping or harm.

• Noise and Light Deterrents: Place bright outdoor lights and radios tuned to talk stations directly at the entrance. The unfamiliar noise and light disrupt their sense of security.
• Ammonia Scent: Soak rags in ammonia and place them in shallow dishes near the den entrance. The strong odor mimics predator urine and encourages them to leave.
• Remove Food Sources: Secure all garbage bins with tight-fitting lids, remove fallen fruit from trees, and never leave pet food outdoors overnight.

The Exclusion Process in Detail

If you choose to use a one-way door, position it over the primary entry hole while leaving all other potential exits open. This ensures the raccoon can leave but cannot re-enter the same opening. Monitor the device regularly and check for signs of activity. Once you confirm the animals have exited, typically within a few nights, the exclusion door can be removed and the entry point sealed permanently with heavy-gauge hardware cloth or solid metal flashing. This final seal is the only way to guarantee they cannot return.

When to Seek Professional Assistance

There are scenarios where handling the issue on your own is not advisable or feasible. If you suspect there are baby raccoons (kits) present, professional intervention is necessary, as the mother will be highly protective. Additionally, raccoons can carry diseases such as rabies and raccoon roundworm, making direct contact or inhalation of dried feces hazardous. Wildlife control professionals have the protective gear, expertise, and legal permits to handle complex situations safely and in compliance with local regulations.

Preventing future invasions is just as important as the initial removal. Once the raccoons are gone, conduct a thorough inspection of the deck area and landscape. Trim tree branches that extend over the roofline, as raccoons use these branches as bridges to your deck. Consider installing a skirt or burying hardware cloth around the base of the deck to eliminate crawl spaces. By removing the appeal and access, you protect your property and deter raccoons from viewing your home as a safe haven.
