How to Prevent Mice from Getting Into the Home

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


Whether you’ve had problems with mice in the past or simply don’t like the idea of potential critters living under the same roof, we’re here with top tips and tricks for rodent proofing your home.


Mice are curious, social creatures who, once inside a home, can breed at an extremely high rate – meaning a couple of ‘harmless’ mice can soon turn into a major infestation. No one likes to think of these unwanted little critters nibbling their way through their dry cupboard and leaving droppings everywhere they go, so read on to learn exactly how to mouse-proof your house… once and for all!

What attracts mice?

First, it helps to get a better understanding of what makes the most appealing type of home for mice to sneak into. These things can generally be broken down into three categories:


  1. Warmth: Mice tend to look for new places to set up home when temperatures are cool, seeking warmth and comfort to hide away from chillier climes.
  2. Shelter: As well as warmth, mice are attracted to anywhere they can get decent shelter. This can often be because they want somewhere safe to breed away from the dangers of the wild.
  3. Food: Mice have an excellent sense of smell and are attracted to any areas in which they detect open sources of food, including things like pasta, cereal, vegetables, rice and even chocolate and cookies (perhaps they’re not so different from us humans after all!).

What keeps mice away?

The best way to deter mice is to make sure you’re not leaving any temptation out for them, and to plug up any gaps, cracks and crevices in your home to stop them getting in (see below for more detailed instructions on this!). For the best chance of keeping mice away, follow these simple rules:


  1. Seal all food properly and never leave anything open – even if it’s up high. Mice are dexterous creatures who can easily climb, so the best way of keeping them away is to lock away food properly and seal open packaging with clips or rubber bands.
  2. Try to clean up any dirty dishes as soon as you’ve eaten to stop mice from sniffing out your leftovers.
  3. Clean all surfaces of crumbs regularly, including inside cupboards and pantries, and your floors.
  4. Clean large kitchen appliances regularly, including around the back, as mice can often nest behind these and make them their home.
  5. Keep pet areas clean and never leave pet food out overnight.
  6. Seal up all holes and possible entrances into your home, as mice can squeeze through spaces as small as a dime!
  7. Check spaces around foundations, pipes, vents and ducts and block them with a mix of steel wool and caulking, or cement. The best mouse and rat prevention is making sure they can't get in.

How to stop mice getting into your garage

To stop mice getting into your garage the key is to make sure you check for any holes or gaps under your garage door and get these fixed as soon as possible. It’s also a good idea to regularly clear out the space, as mice are attracted to clutter which provides the perfect shelter for them. Check out the section below on how to fill mouse holes for further instructions.

How to keep mice away from your bed

People are often squeamish about the prospect of mice climbing up onto their bed but, unless you have a serious infestation, it’s unlikely they’ll do this. If you do have a mouse problem, the best way of keeping them away from your bed is to tackle the problem head on and get rid of them altogether.


To do this, we’d recommend using our Corner Fit Bait Stations which are clean, safe and effective at getting rid of mice quickly. Some people look to use natural remedies to keep mice away from their beds, focusing on smells that mice are said to hate such as peppermint oil.


However, there’s little evidence to back up these DIY methods and while mice might not like the smell of peppermint, it’s unlikely it’ll be strong enough to deter them for long.


One handy trick to naturally keep mice away from your bedroom until you’ve tackled the problem is to use a pest control door sweep on your bedroom door. Mice are adept at squeezing under the tiniest of gaps so applying a door sweep is a good way of blocking their main entryway.

How to plug a mouse hole

The best way to seal mouse holes is with steel wool, as the rodents can’t chew their way through it. However, it’s worth noting that mice may eat some of the steel wool which will kill them rather than simply deterring them. To avoid this, cover your steel wool with silicone caulking before packing the hole tightly with the material. This will both stop the mice from entering your home and from eating the steel wool, so you won’t risk them dying in your walls.


Don’t forget to check spaces around foundations, pipes, vents and ducts to find any possible entryways into your house.


Learning how to keep mice out of your home is a key consideration for anyone who lives in a house that could potentially have cracks and crevices for mice to get into, which most do! New builds may be less vulnerable, but it’s always handy to know how to keep those little critters at bay – just in case.
