Mice Under Floorboards? Here’s What You Need to Know (And How to Get Rid of Them)
If you’re hearing scratching noises at night or noticing odd smells or droppings, you might be dealing with mice under your floorboards. It’s a common problem for London homes and businesses, particularly in older buildings or properties with easy access points.
At Beaver Pest Control, we’ve helped hundreds of property owners deal with mice under floorboards, including upstairs areas. Here’s everything you need to know—plus how to get rid of them for good.
Why Are Mice Living Under Your Floorboards?
Mice are resourceful and can squeeze through gaps as small as 6mm. Floorboards make the perfect hiding place: warm, dark, undisturbed, and full of potential nesting materials. Common reasons for an infestation include:
- Cracks in walls, skirting boards or foundations
- Gaps around pipes and utilities
- Easy access from neighbouring properties or basements
- Food and water sources nearby
Whether it’s mice under floorboards upstairs or on the ground floor, the cause is usually the same—entry points and shelter.
Signs You’ve Got Mice Under Floorboards
Not sure what’s going on under your feet? Look out for:
- Scratching or scurrying noises, especially at night
- Droppings around skirting boards or kitchen cupboards
- Gnawed materials, such as wires, wood or food packaging
- A musky odour near floor vents or beneath furniture
The longer mice are left undisturbed, the more they multiply—and cause costly damage.
How to Get Rid of Mice Under Floorboards
If you’re searching how to get rid of mice under floorboards, here are the key steps:
1. Identify Entry Points
Look for holes near pipes, vents, floorboards, and external walls. These need to be sealed properly to stop re-entry.
2. Set Traps and Baits
Traps can help reduce the population, but placement is crucial—especially if mice are travelling under floors and not openly visible.
3. Professional Proofing
DIY measures often fall short when mice are under floorboards. At Beaver Pest Control, we offer expert rodent proofing to seal hidden gaps and prevent future infestations.
4. Regular Monitoring
For commercial clients, we recommend a pest management contract. This includes routine checks, remote monitoring, and compliance documentation—ideal for food businesses, schools and offices.
