Rat Hearing scratching or scurrying beneath the floor of a Diss property is unsettling, and it is natural to want to know straight away whether it is rats. Under-floor voids are a common place for rats to nest, offering shelter, warmth and easy access to the rest of the house, but noise alone is not enough to confirm what you are dealing with.
Sounds that suggest rats
Rats tend to be most active at night, so scratching, scuffling or gnawing sounds that pick up after dark, particularly running along the same route repeatedly, are a strong indicator. Rats are also heavier than mice, so movement under floorboards often sounds more deliberate and less like a light scurry.
Other signs to look for
- Droppings near access points such as airbricks, skirting gaps or pipework, typically dark and around the size of a grain of rice or larger
- Gnaw marks on skirting boards, joists or cables where they are visible
- A persistent, stale smell, particularly noticeable in enclosed spaces like under-stairs cupboards
- Smear marks along skirting boards where rats have repeatedly brushed against the same surface
- Disturbed insulation or nesting material if you have access to inspect a void
Why guessing is risky
It is easy to mistake other noises, birds in a chimney, expanding pipework, or even mice, for rats under the floor. Equally, assuming a noise is nothing when it is in fact rats can allow an infestation to become established before anything is done about it. In older Diss properties with traditional suspended floors, under-floor voids can be sizeable and provide plenty of room for rats to nest undisturbed for some time.
How a professional inspection confirms activity
A proper inspection involves checking accessible areas of the void, looking at entry points from outside the property, and assessing droppings, gnaw marks and any nesting material found. This gives a clearer picture than sound alone, and helps determine whether you are dealing with rats, mice, or something else entirely.
