Larger droppings in loft insulation
Droppings 8mm wide, often paler than rat droppings, scattered across the insulation rather than along edges. You may also see frayed cable insulation in a single concentrated area.
Daytime running and thumping in the loft is the giveaway — rats and mice are quiet during the day.
Confidence rule — Loft noise between 7am and dusk is squirrels in almost every UK case.

Running noises with weight behind them, often at first light and again in the late afternoon. Sometimes a rolling sound as they move cached food.
After rain, a damp, animal smell at the soffit or near the loft hatch — squirrels carry wet fur straight into the nest.
Gnawed soffit, fascia or barge-board with hair caught in the splinters. Lifted ridge tiles or chewed lead flashing around the chimney.
A football-sized drey of shredded insulation and twigs, usually against a gable end. Two breeding seasons a year (Feb–Apr and Aug–Sep) mean kits are common.
Time of activity is one of the fastest ways to confirm a species — daytime loft noise rules out rats, midnight kitchen scuttling rules out squirrels.
Loud daytime thumping like a tennis ball rolling across the ceiling, paired with hard gnawing on roof joists and short bursts of chittering. Daytime loft noise rules out rats and mice — it's almost certainly a grey squirrel.
