Rats are rarely seen in daylight, so you are more likely to find signs than the animal. This guide covers what to look for and how to tell rats from mice and other wildlife.
Droppings are the most reliable clue. Rat droppings are noticeably larger than those of mice, dark and capsule-shaped, and often found in groups along walls or near food. Fresh ones are soft and shiny; old ones are dry and crumbly. Gnaw marks on wood, plastic and pipes are another sign, as are greasy rub marks along walls where rats brush past on the same route night after night.
Footprints can sometimes be seen in dust, and a tail drag may show between them. Scattering a thin layer of flour or talc in a suspected run overnight is a simple way to check for tracks.
Adult rats are far larger than mice, with thicker bodies and blunt noses. Mice have small droppings, nibble tiny holes and leave only light marks. Young rats can look like adult mice, which causes confusion, but their feet and heads look large for the body. If you are unsure, the size of the droppings is the easiest test.
Squirrels also scamper in lofts, but they are active in the daytime and tend to thump and drag, while rats are mostly night-time visitors. In gardens, voles and shrews make small surface runs and are not usually a house problem. Hedgehogs and foxes can disturb bins, but they leave different droppings and do not gnaw.
Rats and mice move indoors as it gets colder, so autumn is a common time for noises in the roof to begin. Rats breed quickly, so a pair seen in September can be a larger group by the winter. If the signs above are present, do not wait to see what happens.
Sound can narrow things down. Rats tend to be heavier on their feet than mice, so a loud scamper, thump or dragging noise at night is more consistent with a rat. Gnawing is sharper and louder too. Squeaking or fighting sounds may point to a breeding group. Note the time of night and which room the noise is above or beside, because that information helps a technician decide where to look. If the noise changes after cold snaps, that supports the idea of animals moving in for warmth. A torch and a few minutes in the loft with the hatch open will often show runs, droppings and gnawed insulation in one go. Wear gloves and a dust mask, and if you see nesting material or a lot of droppings, step back out and ask for advice.

They are dark brown or black, capsule-shaped and clearly larger than mouse droppings. Fresh ones are moist and shiny, older ones dry and grey. Do not handle them with bare hands; wear gloves, and wash your hands afterwards. A coin placed beside them for scale in a photograph helps a technician identify them.
Yes, more easily than most people expect. A rat can squeeze through a gap not much bigger than a finger-width and will gnaw to widen it. Damaged drains, gaps around pipes and worn air bricks are common routes. Check gaps around pipes and cables regularly.
No. Rats are cautious and mostly active at night, so signs are often found long before the animal is seen. Seeing one in daylight can suggest a large population, because the numbers are forcing some out into the open. Droppings and noise are often the first signs.
