What rat droppings look like
- Size: about the size of a large grain of rice, or a little bigger.
- Shape: capsule- or pellet-shaped, thicker in the middle, with blunt ends.
- Colour: dark brown to black when fresh.
- Where: in groups along the routes rats use: beside walls, behind bins, under sheds and decking, in lofts and along pipes.
Rats tend to leave droppings in clusters where they feed or travel, so finding a small pile in one spot is typical.
Rat droppings or mouse droppings?
Mouse droppings are much smaller and thinner, a few millimetres long, and are scattered widely because mice drop them as they move about. They turn up in kitchen cupboards, drawers and behind appliances. Rat droppings are bigger, chunkier and grouped together. If you find both, or you are not sure, our guide to telling rats from mice compares the other signs, such as noise, gnawing and burrows.
Are the droppings fresh or old?
Fresh droppings are dark, slightly shiny and soft. Older droppings go grey, dry out and crumble if they are disturbed. Fresh droppings mean rats are active now. A good check is to clear an area completely, then look again a day or two later: new droppings mean the rats are still using that route.
Where you find them, and what that tells you
- In the loft or roof space: rats are nesting or travelling inside the building. See loft rat removal.
- Around bins, compost or bird feeders: they are feeding in the garden, and there are probably burrows nearby. See garden rat control.
- Under decking or in a shed: a common nesting spot. See rats under decking.
- Indoors near pipes or drains: they may be coming in from the drains. See rats in drains and sewers.
Lots of droppings in several places usually points to a bigger, settled problem than a few in one spot.
How to clean up rat droppings safely
Rat urine and droppings can spread infections, including leptospirosis (Weil’s disease), which the NHS says is caught from the urine of infected animals such as rats. Clean up carefully:
- Wear rubber or disposable gloves.
- Do not sweep or vacuum dry droppings, because this can stir up dust.
- Dampen the droppings and the area with disinfectant first, then pick them up with damp paper towels.
- Put everything in a sealed bag and put it in your outside bin.
- Wipe the area again with disinfectant and wash your hands well afterwards.
If you feel unwell with flu-like symptoms after contact with rats or their urine, contact your GP or NHS 111 and mention the contact.
What to do after you find droppings
Cleaning up removes the mess but not the rats. Remove easy food (bird seed, pet food, open compost and bin bags), look for burrows and gaps, and get the problem treated before the colony grows. Rat-proofing the way they get in stops them coming back.

Dark brown to black pellets about the size of a large grain of rice, thicker in the middle with blunt ends, usually found in groups along walls and routes rats use.
How can I tell rat droppings from mouse droppings?
Mouse droppings are much smaller and thinner, a few millimetres long, and scattered widely. Rat droppings are larger, chunkier and clustered together.
Are rat droppings dangerous?
They can carry infections, so do not handle them with bare hands or sweep them up dry. The NHS says leptospirosis is spread through the urine of infected animals such as rats.
How do I clean up rat droppings?
Wear gloves, dampen the droppings with disinfectant, pick them up with damp paper towels, seal them in a bag, disinfect the area again and wash your hands.
Does finding droppings mean I have a lot of rats?
Not always. A few droppings in one spot can be a single rat passing through. Droppings in several places, or fresh droppings coming back after you clean, suggest an active colony that needs treating.
