Squirrel Trapping — Buckden

Squirrel or Rat in the Loft? How Buckden Homeowners Can Tell the Difference – Practical Local Guide

Of all the evidence in a roof space, droppings are the most looked at and the most misread, because these two are genuinely similar.

Mouse and rat droppings are easy to separate on size alone. Squirrel and rat are the difficult pair, and it is worth being precise about it.

Honestly: droppings alone are not the strongest evidence here. They overlap enough that we would not identify a roof space from them by themselves, and neither should you. What settles it is the combination of when you hear the noise, whether there is damage at the roofline, and whether there is any evidence at ground level.

The Three Things That Actually Settle It

  1. Time of day. Squirrels are active in daylight and quiet at night. Rats are the reverse. This is worth more than every other piece of evidence combined.
  2. Damage at the roofline. Squirrels make or enlarge an opening high up, and the damage is coarse and visible from the ground. Rats usually enter at low level and climb inside the structure.
  3. Evidence lower down. A rat in a loft has almost always come through the building, so there is usually something to find at ground level — droppings, smearing, a route. A squirrel leaves nothing downstairs at all.

Smear Marks: A Rat Sign, Not a Squirrel One

BPCA describe the greasy residue rats leave where they repeatedly brush the same surface as smear marks. Pronounced dark greasy marks along a joist, at the edge of a gap, or where something passes through a wall point firmly at rats. Squirrels do not produce them in the same way, because they do not travel the same tight, repeated routes through confined spaces.

Please Do Not Handle Them

There is no need. Photograph them with a coin or a ruler for scale, in good light, and photograph the surroundings too. If you have to move anything, wear gloves and wash your hands properly afterwards.

And leave them where they are. The distribution across a roof space is part of the evidence, and it cannot be reconstructed once it has been cleared.

Common Questions

What is the difference between squirrel and rat droppings?
Squirrel droppings are roughly 8 to 12mm, rounder and blunter, and scattered across joists and boarding. Rat droppings are 12 to 18mm, tapered, and grouped along a route.
Can you identify it from droppings alone?
Not reliably — these two overlap enough that we would not, and nor should you. Time of day, roofline damage and whether there is evidence at ground level settle it.
What are smear marks?
The greasy residue rats leave where they repeatedly brush a surface. Pronounced smearing points firmly at rats; squirrels do not produce it in the same way.
Should I clear the droppings before you come?
No. The distribution across a roof space is part of the evidence and cannot be reconstructed afterwards.
