How to Identify Possum Droppings in Sydney Homes
Have you found mysterious droppings in your roof, on your deck, or in your garden? In Sydney, one of the most reliable signs of a possum infestation is the presence of their faeces. However, it’s easy to confuse possum droppings with those of rats, cats, or even bandicoots. Correct identification is essential if you want to address the issue properly.
This guide will help you recognise possum droppings, understand what they mean, and take the right steps if possums are active on your property.
What Do Possum Droppings Look Like?
Possum faeces vary depending on the species, but most share several key characteristics. They are usually larger and more fibrous than rodent droppings and are often found in small clusters near nesting sites or travel paths.
One of the most telling signs of possum droppings is their strong, unpleasant odour. Possums often urinate and defecate at the same time, leaving droppings that are moist from urine. This ammonia-rich smell is typically stronger than that from rodent droppings. When fresh, possum droppings may appear slightly soft and dark brown to black, drying and hardening over time.
- Shape: Cylindrical or pellet-shaped with slightly rounded ends
- Size: 1–2 cm long and about 0.5 cm wide
- Colour: Dark brown or black, depending on diet
- Texture: Fibrous and crumbly when broken apart (contains leaf matter and fruit)
- Smell: Mildly musky, less pungent than dog or cat waste
Fresh possum droppings may appear moist but quickly dry and harden. They’re commonly found beneath roof cavities, along fence lines, or in garden beds where possums forage. Because of their shape and size, possum droppings are often mistaken for those of rats — but key differences exist. For a full comparison, see our guide on possums vs rats and how to tell them apart.
Possum Droppings vs. Rat Droppings
Many Sydney residents mistakenly assume they have a rat problem when it’s actually a possum. The easiest way to distinguish between the two is size and shape.
| Characteristic | Possum Droppings | Rat Droppings |
|---|---|---|
| Size | 1–2 cm long, thicker | 0.5–1.5 cm long, thinner |
| Shape | Rounded ends, often irregular | Pointed ends, smooth and uniform |
| Location | Near nesting or roof access points | Along skirting boards, under sinks |
| Texture | Fibrous, may contain plant material | Compact and solid |
While possum and rat droppings can appear similar at first glance, there are subtle but important differences. Rat droppings are generally more pointed at each end, whereas possum droppings are rounded or blunt. Possum waste also tends to appear in small piles, often directly beneath feeding spots like overhanging branches or decks, while rat droppings may be scattered along walls, roof cavities, or hidden pathways. Identifying the correct species is essential, as the health risks and control methods differ significantly.
Health Risks Associated with Possum Droppings
Possum droppings can carry harmful bacteria and parasites, including Leptospira (which causes leptospirosis) and Mycobacterium ulcerans (which causes Buruli ulcer). These can be transmitted through direct contact with droppings or contaminated soil and water. Symptoms from these infections can range from fever and muscle aches to severe skin ulcers or organ damage if left untreated. Always wear gloves and a mask when cleaning up droppings, and disinfect the area thoroughly afterwards.
Where Are Possum Droppings Usually Found?
Possums tend to defecate in areas they frequently use, such as:
- Under roof entry points or on ceiling joists
- Decks, patios, or balconies near trees or fences
- In garden beds where fruit trees are present
- Along fences, retaining walls, or pergolas
If you find droppings in your roof void, that’s a strong indication a possum has made itself at home. For more on signs to look for, see: Possum in roof
Safe Cleanup Process
When cleaning possum droppings indoors or outdoors, personal protective equipment is essential. Wear disposable gloves, a mask, and enclosed footwear. If droppings are dry, lightly mist them with water before removal to prevent airborne particles. Collect them in a sealable plastic bag and dispose of them in an outdoor bin. Disinfect all affected surfaces using a strong household disinfectant or a bleach solution, and wash your hands thoroughly after finishing.
Which Species Leaves Which Type of Droppings?
Each possum species leaves slightly different droppings, depending on their diet and behaviour. Here’s a quick guide:
- Brushtail Possum: Larger, drier pellets often left in roof spaces
- Ringtail Possum: Slightly smaller, may be found in nests or gardens
- Eastern Pygmy Possum: Very small, rarely found unless nesting is nearby

What To Do If You Find Possum Droppings
If you’ve confirmed the droppings belong to a possum, you’ll need to address the issue both legally and humanely. Here’s what to do:
- Inspect the roof and garden for signs of nesting or entry points
- Do not attempt to trap or move the possum yourself — it’s illegal in NSW
- Contact a licensed possum removal specialist
- Once removed, have the area cleaned and proofed against future entry

Preventing Possums from Returning
Possums are creatures of habit and will return if the area remains accessible. After removal and cleanup, we recommend:
- Sealing all roof access points
- Trimming tree branches away from the roofline
- Covering vents, chimneys, and eaves with possum-proof mesh
- Using deterrents such as motion lights or natural sprays
