Can Mice Climb Walls? STOP Edmonton’s Rodent Invasion

Key Takeaways

1. Mice are excellent climbers on rough surfaces, such as brick, stucco, and wood.
2. Keep them out by sealing gaps, storing food securely, and removing outdoor “ladders.”
3. Act quickly when you notice signs to stop a larger infestation from developing.

If you live in Edmonton, you’ve probably seen a mouse run across your garage or kitchen floor. But everyone asks the same question: can mice climb walls? Yes, they can! But there’s more to know about this.

You need to know how these tiny climbers work. This will help you to protect your home better. This is extra important when it gets cold in Alberta. Mice seek warm places when winter arrives.

When you see their climbing skills, you can take the first step to keep them out of your house.

Can Mice Climb Walls?

Mice are really good at climbing. This often shocks people who find them in their homes. These small animals have sharp claws and bendy bodies. They also have a firm grip.

Yes, mice can climb walls. They do this easily on rough surfaces. Think of brick walls, wooden walls, or bumpy cement walls. Mice are light and stay balanced well. This helps them grab onto tiny holes and cracks in walls.

Even smooth walls don’t stop mice. They use their claws to find tiny spots to hold onto. Their tails help them to stay balanced when they climb.

This makes it hard to keep mice out of houses. They can get in through high places. They climb up to windows, roofs, and where pipes go into walls. This is why mice are such a big problem for homeowners.

Meet Edmonton’s Most Common Mice

In Edmonton, the most common types of mice that enter homes are:

1. House Mouse (Mus musculus): These little mice are very good at surviving indoors. They look for warm places and food during cold or wet weather.
2. Meadow Vole (Field Mouse – Microtus pennsylvanicus): Meadow voles are often called field mice. When it gets cold, they may come inside to find shelter and food.
3. Deer Mouse (Peromyscus maniculatus): Deer mice can sneak into homes, especially in rural areas or houses near open fields.

How Do Mice Manage to Climb?

Mice are natural climbers. A mouse can even jump a foot high from the ground. That means they easily reach cupboards, countertops, and other places you think are safe. Here’s what makes them experts at getting around your house:

1. Sharp claws: Those tiny claws are ideal for gripping rough surfaces, such as brick or wood.
2. Lightweight: Because they weigh so little, it’s easy for them to climb up without slipping.
3. Flexible bodies: Mice squeeze into cracks, twist through gaps, and move through spaces most people wouldn’t expect.
4. Tails for balance: Their long tails help them stay steady when climbing.

Which Walls Can They Climb?

Every wall is different. To help you know where mice might be climbing, here’s a quick guide:

Wall Surface	Can Mice Climb?	What To Know
Brick	Yes	Rough, easy for mice to grab
Stucco	Yes	Lots of bumps and grooves
Wood	Yes	Especially if not smooth
Rough Concrete	Yes	Grooves make it simple
Vinyl Siding	Yes	Depends on whether it’s textured
Metal	No	Too smooth, can’t grip
Glass	No	Slippery, impossible
Smooth Painted Wall	No	No grip for tiny claws

Mice use more than just walls. If you have utility wires, pipes, stacked firewood, or shrubs close to your walls, mice will use them like ladders to get even higher.

Mice on the Inside: What Happens in Your Walls

Once inside, mice don’t just stick to the floor. They move through wall cavities, nest in insulation, and travel from room to room using pipes or wires as highways. Common clues you’ve got visitors. They:

1. Travel through wall cavities and insulation
2. Use pipes and wiring as highways
3. Build nests from paper, fabric, or insulation

Signs to watch for:

• Scratching at night or early morning
• Tiny droppings along baseboards or in cupboards
• Chewed corners, food packaging, or wiring (fire risk)
• Shredded nesting material

Why Mice Climb Walls: The Motives

Mice don’t climb walls just for fun. Here’s why they do it:

1. Food: Mice follow the smell. If you keep snacks, pet food, or grains off the floor, they’ll find a way up.
2. Shelter: Attics and inside walls are hidden, protected, and warm—great places to nest.
3. Safety: Climbing lets mice escape pets, people, and busy spaces.

Edmonton-Specific Prevention: Make Your Home Mouse-Proof

You can keep mice out by being proactive:

1. Block Every Gap

What to do: Look for small cracks and spaces around pipes, doors, and windows. Mice can enter through gaps as tiny as a dime.

Step-by-step: 

• Walk around your house with a flashlight during daylight.
• Check all places where pipes enter your home (kitchen sink, bathroom, basement).
• Inspect door and window frames for gaps.
• Check where your dryer vent, gas meter, and electrical wires enter.
• Feel for cold air coming through cracks.

Use these materials: 

• Steel wool (mice can’t chew through it).
• Caulk to seal over the steel wool.
• Foam sealant for bigger gaps.

Do not forget to check: 

• Around water pipes under sinks.
• Where furnace pipes go outside.
• Foundation cracks near ground level.
• Gap under garage doors.
• Spaces around air conditioner units.

2. Remove Their Ladders

What to do: Move firewood, trim shrubs, and keep anything that touches your walls away from the house.

Detailed steps: 

• Move firewood at least 6 feet away from your house walls.
• Cut tree branches so they don’t touch your roof or siding.
• Trim bushes so there’s 2-3 feet of space between them and your house.
• Remove old furniture, boxes, or junk piled against walls.
• Keep garden tools and lawn equipment away from house walls.

For pipes and cables:

• Wrap smooth metal sheets around vertical pipes.
• Use cone-shaped guards on utility poles near your house.
• Ask utility companies to install guards on their equipment.

3. Store Food Safely

What to do: Use hard containers for all food and pet snacks. Don’t leave food out overnight.

Kitchen storage:

• Put cereal, rice, pasta, and flour in glass jars or hard plastic containers.
• Store pet food in metal containers with tight lids.
• Keep fruit in the refrigerator, not on the counter.
• Put bread in hard containers, not soft bags.
• Clean up crumbs right after meals.

Basement and garage:

• Don’t store birdseed in paper bags.
• Keep grass seed in metal containers.
• Put fertilizer in sealed bins.
• Store holiday candy in hard containers.

Daily habits:

• Wipe counters clean every night.
• Sweep floors before bed.
• Don’t leave dirty dishes in the sink overnight.
• Take out the garbage often, especially during Edmonton’s warm summer months.

4. Check Weatherstrip

To ensure a secure environment: Make sure doors and windows close tightly and repair any worn areas.

• Twice-yearly check (spring and fall):
• Close each door and window, and look for light coming through the gaps.
• Run your hand around frames to feel for cold air.
• Check if the doors bounce when you close them (a sign of a loose fit).
• Look for torn or cracked rubber strips.

What to replace:

• Door sweeps that are bent or have gaps.
• Window weatherstrip that’s hard or cracked.
• Garage door seals that don’t touch the ground.
• Screen doors with holes (even tiny ones).

Edmonton winter tip: Check the weatherstrip extra well before October. Cold weather makes gaps bigger.

5. Choose Smooth Finishes

What to do: When doing repairs, use smooth paints or siding so mice can’t get a grip.

Best options:

• Smooth vinyl siding instead of wood shingles.
• Glossy paint instead of textured paint.
• Metal trim around doors and windows.
• Smooth concrete instead of rough stucco.

When to think about this:

• Before you repaint your house exterior.
• When you replace old siding.
• During basement renovations.
• When you fix foundation cracks.

6. Take Early Actions

What to do: If you spot activity, contact an Edmonton pest control service before it spreads.

Signs to watch for:

• Small black droppings (look like rice grains).
• Tiny bite marks on food packages.
• Strange sounds in the walls at night.
• Pet food disappears quickly.
• Small holes were chewed in boxes or bags.

When to call professionals:

• If you see droppings in more than one room.
• If you hear scratches in the walls often.
• If you find chewed wires or insulation.
• If DIY methods don’t work after 2 weeks.

Edmonton-specific timing:

• Call before November (mice move indoors when it gets cold).
• Don’t wait until after Christmas – mice multiply fast in winter.
• Spring is also a busy time – act fast when the weather warms up.
