Key Takeaways
- Squirrel droppings are barrel-shaped and measure 3/8 to 1/2 inch long with 1/8 inch diameter, while possum droppings are significantly larger (1–3 inches long) and often curve into a distinctive C-shape.
- Squirrel feces vary from beige to dark brown, green, and black depending on diet, whereas possum droppings develop a unique white or yellowish coating as they age.
- Both animals’ droppings can carry dangerous diseases, including salmonellosis and leptospirosis, so proper protective equipment is required during cleanup.
- If you discover wildlife droppings in your attic, crawl space, or living areas, contact Connor’s Pest Pros for professional identification, safe cleanup, and exclusion services.

Squirrel Droppings: Size, Shape, & Location

Typical Size & Measurements
Squirrel droppings typically measure between 3/8 to 1/2 inch in length with a diameter of approximately 1/8 inch. They appear as individual, barrel-shaped, firm, cylindrical pellets when fresh.
What makes squirrel droppings particularly identifiable is their distinctive barrel shape, resembling a wooden barrel with slightly bulged sides and rounded ends. This differs from rat droppings, which tend to be more pointed at the ends.
Color & Texture Variations
One of the most distinctive features of squirrel droppings is their varied coloration, which directly reflects their diverse diet. The color range includes beige and light brown, dark brown, green from vegetation consumption, and black. This variation occurs because squirrels consume everything from nuts, seeds, and fruits to fungi, bark, and occasionally insects.
In terms of texture, squirrel droppings have a rough and fibrous appearance, especially when the squirrel has had a plant-heavy diet. Unlike some rodent droppings, they are not shiny when fresh. As they age, they become lighter and more brittle, and may contain visible plant fibres or nut fragments.
Distinctive Barrel Shape
The barrel-shaped form sets squirrel droppings apart from many other wildlife species. They have rounded ends rather than pointed ones, unlike rat droppings, and slightly bulging sides that give them their characteristic barrel appearance.
This shape remains uniform and consistent across squirrel species, including gray, red, and flying squirrels, and maintains its cylindrical form when fresh. This shape consistency across multiple droppings is another indicator that you are dealing with squirrel waste rather than that of other rodents.
Typical Deposit Locations
Squirrels are creatures of habit but not particularly fastidious about where they leave droppings. Indoors, common locations include attics and crawl spaces near nests, garages and sheds, and wall voids if the squirrels are nesting inside.
Outdoors, you may find droppings on decks, patios, and porches, around the bases of trees, along fence lines, which serve as their travel highways, and beneath bird feeders.
Unlike some wildlife, squirrels do not create designated latrine areas. Instead, they deposit droppings throughout their territory as they go about their daily activities. This means you will find scattered individual droppings rather than concentrated piles, with larger gaps between droppings than you would typically see with mice or rats.
Possum Droppings: Key Identification Features

Size Compared to Other Wildlife
Possum droppings stand out primarily because of their substantial size, measuring between 1–3 inches in length with a diameter that is proportionally thicker than squirrel droppings. They are much larger than squirrel, rat, or mouse droppings.
In the hierarchy of wildlife droppings, possum droppings fall into the medium-sized category alongside raccoon and skunk droppings, making them noticeably smaller than deer or coyote droppings but much larger than rodent droppings.
The C-Shape Characteristic
Perhaps the most distinctive feature of possum droppings is their tendency to curve into a C-shape. This signature identifier separates possum droppings from other similarly sized wildlife waste.
The curved formation occurs naturally as waste passes through the digestive tract and remains a consistent feature across most droppings, though not every one is perfectly curved.
The droppings may appear slightly tapered at the ends while maintaining their overall curve. This curved formation is unique to possums and immediately distinguishes their droppings from other wildlife waste once you have learned to spot them.
Color & Texture Indicators
Fresh possum droppings display a dark brown to nearly black color, a firm, solid appearance, and a relatively smooth texture, compared to fibrous squirrel droppings. As possum droppings age, they develop a unique characteristic: a white or yellowish coating forms as the droppings wither.
The contents of possum droppings may include visible seed husks and berry remnants, insect parts, and small bone fragments from scavenged carrion. Despite their varied diet, the droppings generally maintain a homogeneous appearance.
Where Possums Leave Their Droppings
Unlike squirrels, possums often scatter their droppings randomly throughout their territory. Common locations include under dense shrubbery, beneath decks and porches, inside crawl spaces, along established possum pathways, and near building foundations.
In foraging areas, you may find droppings around garbage cans, near compost bins, under fruit trees with fallen fruit, and around pet food dishes left outdoors.

Frequently Asked Questions (FAQs)
Do squirrels and possums leave droppings in the same places?
Squirrels and possums have similar defecation patterns. They both scatter their droppings randomly throughout their territory, with no designated bathroom areas, often leaving them along travel routes, beneath bird feeders, and near nesting sites.
Can you get sick from touching squirrel or possum droppings?
Yes, both squirrel and possum droppings can pose significant health risks if handled improperly. Squirrel feces may carry salmonellosis, tularemia, and leptospirosis, while possum droppings can harbor bacteria, parasites, and other disease-causing organisms.
Never handle wildlife droppings with your bare hands, and avoid creating dust by sweeping or vacuuming, as this can aerosolize harmful particles. Always use protective gear, including gloves, respiratory protection, and eye protection, when cleaning up any wildlife waste, and thoroughly disinfect the area afterward.
How can I tell if droppings are fresh or old?
Fresh droppings from both squirrels and possums appear dark, moist, and have a glossier surface compared to older specimens. Squirrel droppings typically dry out within a few days, becoming lighter and more brittle.
Possum droppings undergo a more distinctive transformation, developing their characteristic white or yellowish coating as they age due to crystallization of uric acid. To determine if you have an active infestation, clean up existing droppings safely and monitor for new deposits.
Should I clean up wildlife droppings myself?
While small amounts of wildlife droppings can be cleaned up safely with proper precautions, extensive contamination or droppings in enclosed spaces, such as attics, often warrant professional removal.
If you choose to clean up yourself, wear disposable gloves, a proper respirator mask (N95 or better), and protective eyewear. For large infestations or contamination in living spaces, contact Connor’s Pest Pros for safe professional removal with specialized equipment.
What should I do if I find droppings in my attic?
Finding wildlife droppings in your attic indicates an active infestation requiring prompt attention. First, avoid disturbing the waste until properly equipped for safe cleanup, as improper handling can aerosolize pathogens.
Contact Connor’s Pest Pros for a professional assessment—we can safely remove the animal, identify and seal entry points, and provide guidance on proper waste cleanup and disinfection.
