Hearing scratching, scurrying or thumping in the attic after dark is unsettling — and it almost always means something has moved in. Here's how to tell what it is.
Match the sound to the animal
Fast scurrying and scratching, often along walls and typically light, usually means rats or mice. Heavier thumping, walking and dragging sounds point to a larger animal like a raccoon or opossum. Fluttering or squeaking near the roofline at dusk and dawn can indicate bats.
The timing matters too: most attic invaders are nocturnal, so noises that start after dark and quiet down by day are a strong clue you have wildlife, not just the house settling.
Why identification matters
Correctly identifying the animal determines the entire response. Rats need trapping and exclusion; raccoons need a check for babies and humane removal; bats are protected and require legal, seasonally-timed exclusion. Guessing wrong wastes time and can be illegal (with bats).
That's why a professional inspection is the smart first step — it confirms exactly what's up there and how it's getting in.
Get it identified and handled
Whatever is making the noise, the fix follows the same logic: identify, remove humanely, clean up, and seal the entry points. Our nuisance wildlife trapping covers the full range of attic invaders across South Florida.
