How to get rid of mice in your house
Updated 22 October 2026 · By the MintGuard team

Quick answer
Find and seal the gaps mice use, remove food sources, clear any mice already inside (humane traps or a pest controller), then put a long-lasting repellent at every way in to stop new ones arriving.
Getting rid of mice is a four-step job. Skip a step and they'll be back.
Step by step
- 1Confirm it's mice. Look for small, dark droppings (around 3 to 6 mm), gnawed packaging and scratching at night.
- 2Find how they get in. Check under the sink, behind appliances, around pipes and cables, air bricks and under doors.
- 3Remove food. Store food, cereal and pet food in sealed containers and clean up crumbs.
- 4Clear the mice inside. Use humane traps for one or two mice, or call a pest controller for more.
- 5Seal and repel. Seal gaps with wire wool and filler, then place a MintGuard ball at each way in to keep new mice out.
How to tell if you have mice
- Droppings in cupboards, drawers or along skirting boards
- Nibbled food packets
- Scratching in walls or ceilings at night
- A musky smell in enclosed spaces
Mice in the walls or loft
Mice often nest in wall cavities and loft insulation. Put repellent at the access points: the loft hatch, the eaves, around pipes entering walls and in the airing cupboard.
When to call a professional
If you're seeing mice in daylight, finding droppings every day or can hear activity in several rooms, call your council or a pest controller. Then use MintGuard to help stop them coming back.
