How do mice get into the home?

In this article, you’ll find out how mice get into the house. If you were looking to find out about rats instead, you can find more information in our how do rats get into the home article.


Mice can get into your home in a number of ways, usually involving cracks and holes in your walls or the foundations of your property. These entryways into the home often go unnoticed because they don’t have to be very big for a mouse to wheedle its way in.


In fact, mice are capable of wriggling through the narrowest of gaps due to their body shape, which – like all burrowing animals – can be slimmed down to a fraction of its original width. Alongside having a long, narrow body to begin with, mice don’t have collar bones, meaning they can squeeze through minuscule gaps with ease. It’s even been said they can get through holes as small as a dime!


Some properties are more vulnerable to mouse infestation than others, though. For example, those with stacked stone foundations usually have larger gaps – all the better for mice to enter through. Houses with attached garages are also more susceptible to infestation, because these are often left open for long periods of time making it likely that mice will find their way in.


Plus, they tend to be filled with boxes and other clutter, providing the perfect hiding places and shelter for rodents. Remember, as soon as temperatures start to cool, mice will be looking to seek warmth making this the riskiest time for infestations.


Mice can also enter your house through chimneys and gaps in cellar doors, so if you live in a property that has either of these features it’s best to take extra precautions to seal them properly.

Can mice climb walls?

Yes! Mice can reach up to 13 inches up a smooth, vertical wall. They’re excellent climbers, and can go even further on surfaces that provide more grip like brickwork, which is why they’re able to travel up and down chimneys with ease.

Can mice get under doors?

Mice can easily get under doors, so long as there’s at least a small gap between the bottom of the door and the floor, which is usually the case. As a general rule, if you can fit a pencil under a door in your house, then a mouse can get through it too!

Can mice climb stairs?

Mice have no problem climbing up stairs, as long as they’re not made from a slippery material like stainless steel or slick plastic (which is unlikely in a house!). When it comes to carpet, wood, linoleum and tiles, mice can get enough grip to work their way up stairs, and quite quickly at that[1].

Can mice jump?

Yes, most breeds of mice can jump up to a foot high and do so regularly, whether it’s to get to some food that’s been left out or to make a quick escape when they need to. People often think that placing food on higher surfaces is enough to deter mice, but when you consider how nimbly they can get around your house, you might think differently!

How do mice get in the attic?

Darkness, clutter and warm insulation make attics extremely appealing to mice, who usually gain access through small gaps and holes in your roofing. They often scuttle down downspouts and can even jump onto the roof from nearby trees, putting them in the perfect position to find an entry into your home.


Once they’re in there, you may not even notice at first, but mice are very social creatures meaning having a couple of the little critters in your home can soon turn into a huge infestation!


Mice are quick, clever and dexterous creatures who can climb, jump and hide themselves with ease. It’s for this reason that they allude so many homeowners, but with the right tips and tricks you’ll soon get a handle on any potential infestations.
