How to Tell If It’s a Squirrel or a Rat in Your Attic
Hearing strange noises coming from your attic? You’re not alone. For many homeowners, those scurrying or scratching sounds overhead are often the first sign of an unwelcome guest. But here’s the tricky part: is it a squirrel or a rat?
Knowing which pest is in your attic makes all the difference — not just in how you respond, but in how professionals like Specter Pest Control treat the problem. Let’s walk through the key differences so you can get some peace of mind (and peace and quiet) back in your home.
Why the Difference Matters
Squirrels and rats may both take shelter in attics, especially when temperatures drop or they’re looking for a safe place to nest. But they behave differently, cause different types of damage, and require different removal methods.
While rats are more stealthy, creating hidden nests and contaminating spaces, squirrels are active climbers and chewers that can quickly damage insulation, wiring, and wood.
If you suspect activity but aren’t sure what you’re dealing with, here are some signs to help narrow it down.
1. The Sounds: Timing and Type
When and how you hear noises can be your biggest clue.
- Squirrel sounds:
You’ll usually hear squirrels during the day, especially in the early morning or late afternoon. Their movement tends to be fast, with scurrying, rolling, or jumping noises. They’re more active when the sun is out. - Rat sounds:
Rats are nocturnal, so you’re more likely to hear scratching, gnawing, or light thumping at night. Their movements are more subtle — think quiet rustling or scratching inside walls or ceilings.
Pro tip from the Specter team: If you hear something like a marble rolling or light scratching late at night, it’s more likely to be a rat.
2. Entry Points
The size and location of entry holes can also give you a clue.
- Squirrels need a hole about the size of a baseball. They often chew open vents or squeeze through soffits, roof edges, or attic fans.
- Rats can fit through holes the size of a quarter. They tend to enter at ground level first and climb up walls, or use trees and vines to reach your roofline.
3. Droppings
Yes, checking droppings is gross — but it’s one of the most reliable ways to identify what you’re dealing with.
- Squirrel droppings are larger, barrel-shaped, and may appear more scattered.
- Rat droppings are smaller, about the size of a grain of rice, and have pointed ends. They’re usually found in concentrated areas along walls or near food sources.
If you’re not sure what you’re seeing, don’t touch the droppings — both types can carry disease. Contact a pest professional for safe inspection and cleanup.
4. Visible Damage
Both rodents can cause serious damage — but how and where they chew may vary.
- Squirrels are notorious chewers. They’ll gnaw on wooden beams, rafters, insulation, and even electrical wiring. You may also find shredded nesting material in open corners of your attic.
- Rats chew too, but often stay hidden. Look for gnaw marks on wires, plastic, or drywall, especially near the base of the attic or in crawl spaces.
5. Nesting Behavior
- Squirrels often bring in twigs, leaves, or insulation to build visible nests. You may find these in corners or under eaves.
- Rats prefer hidden nests, usually tucked behind insulation or inside wall voids. Their nests are made from shredded paper, fabric, and other soft materials.
What You Shouldn’t Do
Don’t try to seal up entry points until you’re sure the animals are gone. Trapping a squirrel or rat inside your attic can cause more damage and create sanitation problems.
And please — no poison. It might seem like a quick fix, but it often leads to dead animals in hard-to-reach places, causing odor problems and attracting other pests like flies and beetles.
