Discovering mice in your home or commercial premises can be a deeply distressing experience. These nimble pests are remarkably adept at finding small openings, warm shelter, and easy access to food sources. Because mice breed quickly and can contaminate surfaces, identifying an infestation early is vital for protecting your property and keeping your environment safe. In this guide, our team provides clear, expert advice on recognising the warning signs of mice and taking effective action to resolve the issue.

Common Signs of a Mouse Infestation
Mice are primarily nocturnal, meaning they travel and feed mostly under the cover of darkness. Consequently, you are far more likely to notice the distinct indicators of their presence before ever sighting a live mouse. Key signs to monitor include:
- Droppings: Small, dark pellets with pointed ends, frequently found near food cupboards, under kitchen units, or along skirting boards.
- Gnaw marks: Damage on wooden furniture, plastic packaging, skirting boards, and electrical cables, which poses a serious hazard.
- Scratching noises: Distinctive scampering or scraping sounds coming from within cavity walls, beneath floorboards, or inside loft areas at night.
- Unusual odours: A persistent, stale, ammonia-like scent caused by rodent urine, which becomes more noticeable in enclosed spaces.
- Nesting material: Soft, shredded items such as cardboard, paper, loft insulation, or fabric gathered together in warm, hidden corners.
- Grease marks: Dark smudges left on walls and skirting boards from oily fur as mice travel repeatedly along the same pathways.
How to Get Rid of Mice
Eliminating a rodent problem requires a structured, multi-step approach that combines strict hygiene practices, physical proofing, and targeted control measures.
First, focus on hygiene and sanitation. Ensure all food items are stored securely inside airtight glass or durable plastic containers. Clean up crumbs, liquid spills, and food waste promptly, as even minimal food debris can attract and sustain mice.
Second, inspect and proof your property. Mice can squeeze through surprisingly small gaps. Thoroughly check internal and external walls, paying special attention to areas around pipework, air bricks, and doorway thresholds. Fill gaps with materials such as coarse wire wool and sturdy sealant, as mice are unable to gnaw through these durable barriers.
Third, address existing pests. While off-the-shelf traps can catch individual mice, relying solely on DIY methods rarely resolves an entrenched infestation hidden within wall cavities or loft voids.
