You can usually spot squirrel scat by its size and shape. Think small, pill-shaped pellets—about 1/4 to 1/2 inch long—that kind of resemble tiny coffee beans.
If you notice dark, cylindrical pellets piling up near attics, eaves, or under bird feeders, odds are you’ve found squirrel droppings.
Here’s what you need to know to tell squirrel scat apart from rat or mouse droppings. You’ll also learn where squirrels usually leave their waste and what health risks those pellets might bring.
All this helps you figure out if you want to handle cleanup yourself or call in a professional.
What Does Squirrel Scat Look Like?
You’ll typically find small, bean-shaped pellets, often in little piles. The size, color, and where you find them can help you tell squirrel droppings from other rodent feces.
Shape and Size of Squirrel Droppings
Squirrel pellets look short and cylindrical, with rounded or sometimes slightly pointed ends. Each pellet usually measures around 3/8 inch long (about 9–10 mm) and about 1/8 inch (3–4 mm) in diameter.
They’re about the size of a grain of rice or a coffee bean. You’ll usually see them in loose clusters or small piles, not scattered everywhere.
Ground squirrels, tree squirrels, and flying squirrels all leave behind this pellet shape. Flying squirrel pellets might be a bit smaller, but not by much.
If you see lots of uniform pellets grouped together, that’s a strong clue you’re dealing with squirrels instead of a one-time visitor.
Color and Texture of Squirrel Feces
Fresh squirrel droppings look dark brown or almost black. As they dry, they fade to light brown, tan, or even gray.
The surface can look smooth or a little glossy, especially if the squirrel’s been snacking on oily nuts or seeds. Texture depends on what they’ve been eating.
If their diet’s high in fiber, you might notice visible plant fibers in the pellets. Sometimes you’ll spot bits of seeds or fruit mixed in.
Don’t touch droppings directly—dried dust can carry germs. Always use gloves and a mask if you need to clean them up.
How to Identify Squirrel Poop vs Rat Poop
Squirrel pellets are rounder and more uniform than rat droppings. Rat feces usually look longer, tapered at the ends, and can reach up to 1/2 inch long.
Squirrel poop is more like short, stubby cylinders, while rat droppings are elongated and a bit banana-shaped. Color doesn’t always help, since both start dark and get lighter as they age.
Use the size, shape, and how they’re grouped to tell the difference. Clustered, uniform pellets? Probably squirrels. Varied sizes and longer, tapered pieces? More likely rats.

Locations Where Squirrel Pellets Are Found
Squirrels like to use certain spots as their bathroom. In yards, you’ll often find pellets under bird feeders, at the base of trees, or along fence tops.
Inside attics or wall spaces, tree and flying squirrels tend to leave piles in corners, near their nests, or along rafters. Ground squirrels usually leave more pellets near burrow entrances and along their runways.
You probably won’t see pellets scattered all over the lawn. Squirrels seem to prefer a few regular spots.
If you’re searching for squirrel scat, check dark, sheltered areas where they rest or stash food. For more tips and photos, check out this guide on what squirrel poop looks like.
Health Risks and Safe Cleaning of Squirrel Droppings
Squirrel droppings can carry bacteria and parasites that mess with breathing and digestion. Using the right protection and cleaning steps—and getting rid of animals quickly—keeps your risk lower.
Diseases Linked to Squirrel Droppings
Squirrel feces can contain bacteria like Salmonella and Leptospira. Salmonella can cause fever, stomach cramps, and diarrhea if you touch contaminated surfaces or food.
Leptospirosis spreads through urine and feces. It can bring on flu-like symptoms, jaundice, or even breathing problems if things get bad.
Hantavirus is much more common in mice and rats, but any rodent droppings that dry out can release dust you might breathe in. That raises your risk of lung infection or serious respiratory illness.
If your immune system isn’t strong, be extra careful.
How to Clean Squirrel Feces Safely
Before you touch anything, put on gloves, a snug N95 mask, and eye protection. Spray droppings with disinfectant or a 10% bleach solution and let it sit for at least 10 minutes.
Don’t sweep or vacuum dry droppings; that just sends dust everywhere. Use paper towels to pick up the wet waste, then toss everything into a sealed plastic bag.
Clean the spot again with disinfectant. Throw out your gloves and mask, or wash any reusable gear in hot water.
Don’t forget to wash your hands really well with soap and water for at least 20 seconds after you’re done. If you’re dealing with a big mess in the attic or a large pile, it’s honestly safer to call a pro who knows how to handle wildlife droppings.
What to Do in Case of a Squirrel Infestation
Noticed a bunch of droppings, chewed wires, or weird noises in your walls or attic? Chances are, you’ve got a squirrel problem on your hands.
Don’t try trapping or handling squirrels yourself—especially if you’re not sure about the laws or which species you’re dealing with. It’s just safer to call a licensed wildlife removal company. They’ll know what to do.
A good wildlife pro usually sets humane traps, removes the animals, and seals up entry points like eaves, roof vents, or those annoying gaps around pipes. Once they’re gone, you might want to get your attic cleaned up and replace insulation if droppings or urine are all over the place.
If someone in your home starts feeling sick after exposure, go see a doctor and mention the possible contact with squirrel droppings. Not sure what you’re looking at, or how to clean up? Check out this photo guide on squirrel feces identification and cleanup.
