Can Raccoons Climb Brick Walls And How To Stop Them?

Raccoons are remarkably skilled climbers, and yes, they can climb brick walls. Their sharp claws and strong hind legs allow them to grip the mortar lines between bricks, which act like tiny ledges. However, brick is not their preferred surface, and understanding why they climb—and what makes brick challenging—is the key to stopping them effectively.

Why Raccoons Climb Brick Walls

Raccoons do not climb for exercise. They climb to reach food, water, or a safe place to rest. A brick wall usually leads to a roof, and a roof often leads to an attic, chimney, or a warm spot under solar panels.

They are also highly motivated by smell. If you have a trash can near the wall, a compost pile, or pet food left outside, you are giving them a reason to explore. Removing the reason is the first step in stopping the climb.

Raccoons are nocturnal. They are most active between dusk and dawn. If you see damage in the morning, it likely happened overnight. This timing matters because you need to inspect and repair entry points during the day, when the animal is likely resting elsewhere.

How Raccoons Actually Climb Brick

Brick walls are not smooth surfaces. The mortar lines between bricks create small horizontal gaps. Raccoons use these gaps as footholds. Their claws are strong enough to grip the rough texture of the brick and the slightly recessed mortar.

Raccoons do not have sticky pads like geckos. They cannot climb glass, polished metal, or completely smooth painted surfaces. They need something to grip. Brick offers enough texture and tiny ledges to make climbing possible.

They also use their bodies efficiently. A raccoon will brace its back feet on one mortar line while reaching up with its front paws to the next line. This is called “chimneying” when they use two opposing surfaces, but on a flat wall, they rely on claw grip and leg strength.

Corners are easier for them. A raccoon can press its back against one wall and its feet against the other, creating friction. This is why you often see raccoon damage concentrated near the corners of a house rather than in the middle of a flat wall.

Signs a Raccoon Is Climbing Your Wall

You may not see the raccoon itself. Look for the evidence it leaves behind.

• Scratch marks: Look for dark scuff marks or claw scratches on the brick, especially near downspouts, corners, and gutter edges.
• Droppings: Raccoon feces are dark, tubular, and often contain undigested seeds or berries. They usually appear along the top of walls or near the roof line.
• Damaged gutters: Raccoons climb onto roofs and often damage gutters while trying to reach the edge of the roof.
• Noises: Thumping, scratching, or chattering sounds in the attic or chimney at night.
• Displaced shingles or vents: Raccoons are strong enough to pull up loose shingles or pry open roof vents.

If you see any of these signs, do not assume the problem is gone. Raccoons are creatures of habit. They will return to a reliable food source or den site repeatedly.

How to Stop Raccoons From Climbing Brick Walls

Stopping a raccoon from climbing is about removing the footholds and the motivation. You do not need to make your house impenetrable to every animal. You need to make it easier for the raccoon to go somewhere else.

Install a raccoon guard on downspouts. Downspouts are like ladders for raccoons. A smooth metal sleeve that wraps around the downspout, about 3 to 4 feet off the ground, prevents them from getting a grip. This is a common and effective deterrent.

Trim tree branches. Any branch that comes within 8 to 10 feet of your roof is a bridge. Raccoons will use it. Cut branches back so they do not overhang the house.

Secure trash cans. Use cans with locking lids or store them in a shed or garage. If you cannot move them, secure the lid with bungee cords or a ratchet strap. Raccoons can open many standard lids with their dexterous paws.

Remove outdoor pet food. Do not leave pet food bowls outside overnight. This is one of the most common attractants. Feed pets indoors or bring the bowls in before dusk.

Install motion-activated lights or sprinklers. Raccoons prefer darkness. A sudden burst of light or water can startle them and condition them to avoid the area. These are not guaranteed solutions, but they are low-cost and non-harmful.

Apply a commercial raccoon repellent. Some products contain predator urine or strong scents like capsaicin. Their effectiveness varies. No repellent has been proven to work consistently in all situations. Some research suggests they work for a short time but lose potency after rain or over several days.

Seal entry points at the roof line. If the raccoon is climbing to get into your attic, the real problem is the hole at the top. Inspect your roofline for gaps, loose vents, or damaged soffits. Repair these during the day when you are certain no animal is inside.

What Does Not Work Against Raccoons

Some common methods are ineffective or unsafe. Knowing what to avoid can save you time and frustration.

Ultrasonic devices: No strong evidence shows that ultrasonic pest repellents deter raccoons. Raccoons may ignore the sound entirely.

Mothballs: Mothballs are pesticides. Using them outdoors is illegal in many areas, and they are not effective at repelling raccoons. They also pose a health risk to children and pets.

Ammonia-soaked rags: The smell may deter raccoons temporarily, but it fades quickly and is not a reliable long-term solution. It can also be hazardous if placed where children or pets can reach it.

Electric fences: These work but are expensive and require professional installation. They are more appropriate for farms than for a typical suburban home.

Poison: Never use poison. It is inhumane, illegal in many jurisdictions for raccoons, and poses a serious risk to pets, children, and other wildlife. A poisoned raccoon may die in your wall or attic, creating a severe odor and a fly infestation.

When to Call a Professional

If a raccoon is already living in your attic, chimney, or crawl space, call a wildlife removal professional. Do not attempt to remove it yourself. A trapped or cornered raccoon can bite and may carry rabies.

Professionals use exclusion techniques. They install one-way doors that let the raccoon leave but not return. This is the most humane and effective method. They also know the local laws regarding wildlife removal, which vary by state.

If you find a baby raccoon, do not touch it. The mother is likely nearby. A professional can assess whether the babies are old enough to leave on their own or need to be reunited with their mother. Separating a mother from her kits is stressful for the animals and often results in the babies dying.

After removal, the professional should help you identify and seal all entry points. This is critical. If you only remove the raccoon and do not fix the hole, another animal will move in within weeks.

Can Raccoons Climb Brick Walls And How To Stop Them: The Bottom Line

Yes, raccoons can climb brick walls because the mortar lines provide footholds. They are persistent, intelligent, and strong. But they are also predictable. They follow regular routes and return to reliable food sources.

Your best defense is a combination of removing food sources and eliminating easy climbing routes. Secure your trash, feed pets indoors, trim branches, and install guards on downspouts. If the raccoon has already gained access to your home, contact a professional to handle the removal and then seal the entry points.

No single method is a magic fix. A layered approach—removing attractants, blocking climbing routes, and repairing entry points—is the most effective strategy. This is not about making your home a fortress. It is about making it less convenient for the raccoon than the neighbor’s yard.
