Can Mice Climb?

A mouse might not take the conventional route to climb stairs as humans do but they can easily get upstairs if they want to.

As mentioned, mice are persistent, and a human staircase will do little to stop them from exploring the confines of your house or business property. Not only can they run or jump up the face of each step, there’s also often a handrail or bannister for them to climb that makes the ascent much easier.

If you’ve spotted the signs of a rodent infestation in an upstairs part of the property, don’t assume you’re imagining things as mice are always on the hunt for the best place to nest, even if it’s a bit more effort to get there.

Erase the image of a mouse scaling a 90-degree angle. They can’t. However, they can find ways to overcome the challenge.

Mice might not be able to run up a flat surface but most UK houses and buildings are made from brick or concrete and this kind of porous material makes it easier for the tiny rodents to grip.

Most buildings also offer mice the perfect climbing aid such as wiring or pipework or vines and plants, making it easier for them to find a way inside without needing to show off their balance and acrobatic skills.

Perhaps even more unsettling than the sight of a mouse orienteering its way up your walls, is the idea that it is somehow phasing through your windows.

If mice can climb walls, there’s no reason why they wouldn’t be able to access an open window above ground level or exploit any gap or opening around your windows as an entry point.

It’s unlikely that a brazen mouse would lunge through a recently opened window, but poorly sealed windows and doors or windows left open in unused rooms make it easy for a family of mice to move in.

Mice are relentless in their search for warm shelters to build nests and access to food sources. Once they identify your home or business property as a suitable target, they become determined pests capable of chewing, gnawing, and climbing to find suitable entry points. While a mouse won’t always have to climb to find a way in, it’s certainly not uncommon for them to scale your walls or get upstairs if they know it will pay off and offer them food and shelter.

The short answer is yes, but it depends on the material your walls are made out of. If your walls are made out of solid brick, then it is very unlikely that a mouse would be able to make its way inside. However, if your walls are hollow, particularly internal walls and cavities, then it will be much easier for them to navigate.

In addition, mice are extremely flexible, making even the tightest of squeezes an option for them.

Mice can often be found using pipes to get around as well, both internally and externally. Even if a mouse isn’t in your walls, per se, it may be inside the pipes that run throughout them. If you think this might be the case, check the pipe entrances for any signs of life, including mouse droppings.

Make sure your pipes are well maintained and not corroded due to weather conditions. A mouse will leave no gap untried.
