Squirrel droppings can be identified by their size, shape, appearance and the location where they are found. Squirrel poo can resemble the droppings of other rodents, so several clues should be considered together rather than relying on one feature alone.
This guide explains what squirrel droppings look like, common grey squirrel evidence, droppings found in lofts or attics, and the main identification differences to check.

What Do Squirrel Droppings Look Like?
Squirrel droppings are usually small, dark pellets that can be identified by looking at their size, shape, colour and where they are found. Their appearance can vary, so squirrel poo should not be identified from a single feature alone.
Droppings are useful evidence because they can help narrow down which animal has been active in an area. However, squirrel poo or squirrel poop can resemble the droppings of other rodents, particularly when viewed without other signs such as noises, nesting material or damage nearby.
Squirrel Poo: Size, Shape and Appearance
Squirrel poo is generally pellet-shaped and may appear dark grey, brown or black. The Mammal Society describes squirrel droppings as small, rounded pellets that can measure around 0.5–0.8 cm long and approximately 0.5 cm thick, while also noting that their size can vary considerably.
Colour can also vary with diet, so it should not be used as the only identification feature. When examining possible squirrel scat or faeces, compare the overall shape, dimensions, location and other evidence around the same area rather than relying on colour alone.
Grey Squirrel Droppings
Grey squirrel droppings can be dark grey or black and usually have a small, rounded pellet-like appearance. Diet can influence their colour and other characteristics, which means there may be variation between individual droppings.
Red squirrel droppings should not be distinguished from grey squirrel droppings by appearance alone. UK mammal guidance describes squirrel droppings generally rather than giving a distinct diagnostic pattern for each species, so species identification should also consider the animal itself and other field signs.
Squirrel Droppings in a Loft or Attic
Squirrel droppings may be found in lofts and roof spaces where squirrels have been active. In a property, identification is stronger when the droppings appear alongside other evidence such as disturbed insulation, gnawing, nesting material or repeated movement around the roof space.
Droppings alone do not prove that squirrels are currently occupying the space. If other evidence is present nearby, compare it with the wider signs of squirrel activity in a loft or attic.
Animal droppings should not be handled directly simply for identification. UK wildlife guidance recommends using characteristics such as size, shape, colour and contents while avoiding direct contact.
How to Avoid Misidentifying Squirrel Droppings
Squirrel droppings can be confused with other rodent droppings, so identification should use several features rather than one measurement. Size, shape, location and other signs of animal activity can all help narrow down the likely source.
Squirrel vs Rat Droppings
Squirrel and rat droppings can look similar, which makes identification from droppings alone difficult. BPCA guidance describes squirrel droppings as barrel-shaped and notes that they may be mistaken for rat droppings.
The surrounding evidence can therefore be just as important as the pellets themselves. Droppings in a roof space together with daytime movement, disturbed insulation or squirrel-related gnawing may support squirrel identification more strongly than the droppings alone.
Mouse droppings are generally smaller and thinner than squirrel droppings, but size alone should not be used to identify the animal. Compare the droppings with their location and any other evidence found nearby.

Frequently Asked Questions
Animal droppings should be treated cautiously and should not be touched directly. UK wildlife guidance warns that animal poo can contain harmful microorganisms. For identification, look at visible features such as size, shape and colour without handling the droppings with bare hands.
Squirrel droppings may be less noticeable because they are small and can be left in sheltered or less visible locations. Their dark pellet-like appearance can also make them difficult to spot among soil, insulation or other debris. Finding no obvious droppings does not rule out squirrel activity.
Droppings alone are not a reliable way to distinguish a red squirrel from a grey squirrel. UK mammal identification guidance describes squirrel droppings generally, so species identification should also consider the animal's appearance, location and other field signs.
No, finding droppings does not by itself prove that squirrels are currently occupying the loft. Look for additional evidence such as recent noises, disturbed insulation, gnawing or repeated activity around the roof space before drawing a conclusion.
Yes, a clear photograph can help when comparing the size and appearance of possible squirrel droppings. The Mammal Society recommends including an object of known size, such as a coin or standard pen, in a photograph when a ruler is not available. Avoid touching the droppings directly.
