Squirrel vs. Raccoon in the Attic: How to Tell the Difference
If you've heard scratching, thumping, or scurrying overhead, your first question is probably: what's up there? Squirrels and raccoons are two of the most common attic intruders for New Jersey homeowners, and while they can cause similar headaches, they behave very differently once they're inside. Knowing which animal you're dealing with can help you understand the urgency of the problem and what kind of removal approach it needs.
Listen to the Noise
The sounds an animal makes in your attic are often the first clue to its identity.
- Squirrels are active during the day. If you're hearing quick scampering, light scratching, or rolling/chewing noises in the late morning or afternoon, a squirrel is the more likely culprit.
- Raccoons are nocturnal and much heavier on their feet. Loud thumping, heavy footsteps, or low growling and chattering sounds after dark point toward a raccoon.
- Timing matters. Consistent daytime activity usually means squirrels, while nighttime noise is a stronger sign of raccoons.
Compare the Damage
The two animals also leave behind very different types of damage.
- Squirrels gnaw. They chew through wood, soffits, and even electrical wiring to keep their teeth in shape and to widen entry points. Look for small, round chew holes about 2–3 inches in diameter.
- Raccoons tear. They're strong enough to rip shingles, pull back flashing, or tear open vents to force their way inside. Their entry holes tend to be larger and more jagged, often 6 inches or more.
- Insulation disruption from a raccoon is usually more severe, since females often flatten and shred large sections to build a nesting area for their young.
Check Droppings and Nesting Material
Droppings are one of the clearest ways to confirm which animal you're dealing with.
- Squirrel droppings are small, pellet-shaped, and often found scattered near nesting areas or along beams.
- Raccoon droppings are larger, cylindrical, and may contain seeds or berries, since raccoons are opportunistic eaters.
- Nesting material also differs: squirrels build compact nests from leaves, twigs, and shredded insulation, while raccoons create larger, messier nests and may use the same corner of the attic repeatedly.
Why It Matters for Removal
Squirrels and raccoons require different handling, which is part of why an accurate ID matters before any removal begins.
- Litter timing is a key factor. Raccoons often have their young in late winter through spring, which can affect how and when it's safe to remove a family without separating a mother from her kits.
- Entry points differ in size and location, so sealing a raccoon-sized gap won't necessarily stop squirrels, and vice versa.
- Repeat activity is common with both species if the original entry point isn't fully repaired, which is why removal and exclusion typically go hand in hand.
