As temperatures drop and food becomes more scarce outdoors, mice often seek shelter in homes, creating an unpleasant and potentially hazardous infestation. Understanding how mice get into homes and implementing measures to stop them can help homeowners avoid a larger problem. This guide explores how to identify entry points, provides practical tips on mice prevention, and explains the best way to get rid of mice once they move in.
If you already have signs of activity, such as droppings or gnaw marks, or you can hear scratching or notice a persistent smell, arranging professional mouse pest control early can help prevent a small issue from becoming a larger infestation.
Although mice and rats have different habits and entry points, both can damage property, contaminate food, and create hygiene concerns. Visit our rodent pest control page for help identifying and dealing with rodent activity in your property.

How Do Mice Get into Homes?
Mice are skilled at squeezing through tiny openings. Some common ways mice get into homes include:
Gaps and Cracks in Walls
Even a crack as small as a pencil eraser can allow a mouse to slip inside.
Openings Around Windows and Doors
Poorly sealed windows and gaps under doors are prime entry points.
Utility and Plumbing Lines
Mice can follow pipes and wiring into your home, making basements and kitchens common starting points for infestations.
Roof Openings and Vents
If mice reach your roof, they may enter through soffit vents, loft vents, or even gaps in the chimney.
Other common access points might include:
- Damaged air bricks
- Gaps around extractor fans
- Broken drain covers
- Badly-fitted garage doors
- Openings, such as for cables, for instance.
Identifying these weak spots can help you develop a strategy to keep mice out of the house.
How to Prevent Mice in Your House
Now that we know how mice get into homes, let’s explore some effective ways to prevent mice in your house:
Seal Cracks and Openings
Inspect your home for any gaps or cracks, especially around windows, doors, and the foundation. Use steel wool or sealant to block these entry points, as mice cannot chew through these materials.
For longer-lasting proofing, use a suitable sealant alongside rodent-proof materials such as wire mesh or metal plates, which are hard to gnaw through, where necessary. Be sure to check around pipework, cable entry points, vents and gaps beneath external cladding.
Use Door Sweeps
Installing door sweeps can stop mice from getting into houses by preventing them from sneaking in under doors. This is especially important for external doors leading to garages or basements.
Secure Food Sources
Mice are attracted to food left out in open spaces. Store all food in containers and keep kitchen counters clean. Regularly empty bins, as even small bits of food waste can attract rodents.
Do not forget to check how secure or safe any pet food, birdseed or dry food is stored. It is best to keep these sealed in strong containers to make sure they can’t be chewed through.
Reduce Clutter
Mice look for sheltered spots to nest, so keeping your home clean and clutter-free reduces potential hiding places. Reducing unnecessary clutter is key to preventing mice from getting into homes.
Maintain Your Garden
Trim bushes and trees, as overgrown vegetation gives mice cover to approach homes. You should also be aware of having:
- Compost piles
- Bird feeders
- Rubbish
- Bits of timber
- Compost.
Mouse Prevention Checklist
Use this checklist to reduce the risk of mice entering your home:
Inspect exterior walls, brickwork and foundations for gaps or cracks.
Seal openings around pipes, drains, cables and utility lines.
Fit door brushes, or door sweeps, to external doors, garage doors and basement entrances.
Repair damaged window seals, vents, air bricks and roofline gaps.
Store dry food, pet food and bird feed in sealed containers.
Clean up crumbs, spills and food waste promptly.
Empty kitchen and outdoor bins regularly, and keep bin lids closed.
Reduce clutter in lofts, garages, sheds, cupboards and under-stair storage areas.
Trim vegetation away from the exterior of the house.
Check for signs of mice, including droppings, gnaw marks, shredded nesting material and scratching noises.
If you find repeated signs of rodent activity despite taking these steps, a professional inspection can identify hidden entry points and nesting areas that may be difficult to find without specialist knowledge.

How to Stop Mice from Getting Into the House
In addition to mouse prevention tips, there are several measures you can take to actively stop mice from getting into the house if you suspect they are nearby. Be sure to follow these expert tips below:
Set Up Traps Near Entry Points
Placing traps around known entry points, such as garage doors and basements, can be an effective way to capture and stop any mice from getting into a house. Snap traps are generally considered to be more effective than glue traps, but both are useful in specific situations.
You might also place traps:
- Carefully along walls
- Behind appliances
- Near suspected access points
- In areas where you have seen droppings.
Safety tip: Please remember to check traps frequently and always keep them away from children and pets.
Consider Natural Deterrents
Mice dislike the smell of peppermint oil and clove oil. Applying these oils around entry points may help deter mice from getting into the house. Another worthwhile option is to place used cat litter outside entry points; the scent of a predator can strongly discourage mice.
Natural deterrents may provide limited short-term support, but they might not always have the same effect as awareness of potential entry points, sanitation, or professional treatment, for instance.
Use Electronic Repellents
Ultrasonic repellents emit sound frequencies that are unpleasant to rodents and can be a useful tool for stopping mice from entering homes. However, these should be paired with other methods for the best results.
The Best Way to Get Rid of Mice
If a mouse infestation, or any other rodent infestation, has already taken hold on a property, the best way to get rid of mice is often a combination of traps and professional pest control services:
Try Multiple Trap Types
Using a combination of snap traps, glue traps, and live-capture traps can help manage an infestation effectively. Place traps along walls, as mice prefer to travel along the edges of rooms.
For households with pets or young children, consider the placement and type of trap carefully. A pest control professional can recommend an approach that is suitable for the property and level of activity.

Eliminate Nesting Materials
Mice use materials like paper, cloth, and insulation to build nests. Removing potential nesting supplies is one of the best ways to get rid of mice, as it reduces their incentive to stay.

Frequently Asked Questions About Mice in Homes
What is the smallest gap a mouse can get through?
Mice can squeeze through surprisingly small gaps, often around 6–7 mm wide. That means openings around pipes, damaged brickwork, door frames, vents and cables can all provide access to your home.
Why do mice come into houses in autumn and winter?
Mice often enter homes when temperatures fall because properties provide warmth, shelter, water and accessible food. However, mice can enter homes at any time of year if suitable food sources and entry points are available.
What are the first signs of a mouse infestation?
Common signs might be:
- Small dark droppings
- Gnaw marks on food packaging or cables, paper or fabric used for nesting
- Scratching noises in walls or ceilings
- A stale or musky smell.
Can I get rid of mice myself?
Small, isolated mouse problems may sometimes be managed with proofing, good hygiene and correctly placed traps. However, recurring activity, large numbers of droppings, activity in wall cavities or lofts, or signs of rats may require professional pest control.
How can I keep mice from returning after treatment?
One of the most important steps is to proof the property and to be aware of potential weak spots or risky areas. A quick mouse-proofing checklist might be to:
- Seal access points
- Fit door sweeps
- Store food securely
- Reduce clutter
- Maintain the garden so rodents won’t want to stay near the house, as clutter can provide shelter for them.
When should I call a professional mouse control company?
Contact a professional if you see frequent mouse activity, find signs in multiple rooms, hear scratching in walls or ceilings, cannot identify where mice are entering, or have tried traps and prevention methods without success.
