Worried about mice entering your home? The best way to avoid mice in your home is to know how to prevent them getting indoors in the first place. This can sometimes be difficult to do even when best practices are followed.
Mice are cunning creatures. They are strong climbers, incredibly agile and can pass through openings the size of a dime. If they have set their sights on your home, your property would have to be sealed tight in every possible way, to prevent mice getting inside.

As prevention is the best cure, we have compiled this list of rodent proofing & exclusion tips and strategies to help you keep mice out of your home.
Eliminate Mouse Entry Access Points
Thoroughly inspect and eliminate the following mouse entry points into your home by sealing entry points using caulk, concrete, coarse steel wool or aluminum & copper mesh:
- Look inside and under all kitchen cabinets
- Check kitchen walls and floor corners for any visible cracks
- Check if there are any entry points behind your refrigerator, freezer and stove
- Inspect pipes and plumbing under kitchen sinks, garbage disposal systems, etc
- Look for access points around pipes leading to hot water heaters
- Ensure that windows and doors are sealed appropriately to impede entry
- Living Spaces
- Look inside, behind and under all wardrobes, cupboards or other internal storage areas to ensure there are no cracks in walls or floor corners
- Check for cracks in floors and walls between cabinets
- All plumbing and electrical points that may include openings in or around surrounding walls or floors

Is Mouse Prevention Too Late for My Home?
If you have already spotted typical signs of mice in your home, then you need to act fast to get rid of the pests
Prevention is never too late though and you should still consider future proofing your home to prevent any further infestations - Ehrlich can advise you of the best methods for prevention, and our Year Round Protection Plan could be of real benefit in this case.
Natural Mouse Prevention Methods
If you would prefer to approach mouse prevention in a more organic way there are certain herbs, which are reported to repel mice, although there is no clear scientific evidence to back these up. Please read our tips below for further help:
- Mint - mice are said to dislike mint, so growing mint in your garden or having a potted mint plant in your kitchen may help to repel mice. You can also try using peppermint extract - with water in a spray, or add some to your mop bucket.
- Ultrasonic Devices – these work by emitting a sound that mice and other rodents don’t like but which can’t be heard by people. However, there’s lots of reports that these devices don’t work very well as mice simply get used to & ignore the uncomfortable noise, and even the Federal Trade Commission has stated that they are ineffective.
How Your Pets Can Help to Deter Mice
Most pet owners are aware of their cat or dog’s natural ability to chase and catch rodents and sometime sadly innocent birds in the yard. This natural instinct though can help to keep possible mice invaders out of your home.
- Cats – cats can and do catch mice, but they will tend to play with them, which can cause a mess. Whilst owning a cat may prevent an infestation, normal pet cats or even mousers (cats trained to catch mice) are not likely to be able to get rid of a mouse infestation on their own.
- Dogs – perhaps surprising, but some dogs are excellent at catching mice.
- Birds – owls, particularly barn owls, probably shouldn’t be classed as pets but they can be encouraged to nest in your garden. They will make short work of any mouse population outside your home.
