Understanding the Key Factors That Bring Possums Into Your Property
If you’re hearing strange thumps in your ceiling or finding droppings in your backyard, there’s a good chance you’re sharing your space with a possum. But what attracts possums to Sydney homes in the first place?
These marsupials are highly adaptable and resourceful, and urban environments like Sydney offer ideal conditions for nesting and feeding. In this guide, we explore the most common reasons possums are drawn to residential properties — so you can identify and reduce the chances of an infestation.
1. Easy Access to Food Sources
Like most wild animals, possums follow their stomachs. Food availability is one of the biggest attractants, especially in well-vegetated suburbs and backyard gardens.
Common food sources include:
- Fruit trees (especially fig, apple, mango, and citrus)
- Vegetable patches and herb gardens
- Uncovered compost bins
- Pet food left outside overnight
- Kitchen scraps or bins with loose lids
Possums are mostly herbivorous but are opportunistic feeders. Their diets shift in urban settings — as outlined in our article on the diet of possums in urban vs wild areas.
2. Warm, Dry Nesting Sites
Urban possums are constantly searching for safe, sheltered areas to sleep during the day. Your home may be a prime target without you even realising it.
Popular nesting locations include:
- Roof cavities and attic insulation
- Wall voids or underdeck spaces
- Garages and sheds
- Dense shrubs or vine-covered fences
For species that prefer tree canopies, learn the differences in our guide to Tree-Dwelling vs Roof-Dwelling Possums.
Once possums find a suitable nesting site, they often stay long-term — particularly if the space is near food. For more information, see Habitat Preferences of Sydney Possums.
3. Entry Points in Roofs or Eaves
Possums can squeeze through surprisingly small openings to enter your roof space. Any of the following can serve as access points:
- Broken or lifted roof tiles
- Gaps in fascia boards or eaves
- Damaged vent covers
- Uncapped chimneys
They’re agile climbers, so fences, tree limbs, and even powerlines can provide the perfect bridge to your rooftop. Over time, they may cause further damage once inside, including gnawing and soiling insulation.
Possums are expert climbers thanks to their specialised claws. Read more about how their claws and teeth help them climb and chew through obstacles.
4. Dense Vegetation or Overhanging Trees
Homes with lush gardens and mature trees are more likely to attract possums — especially Ringtail Possums that build nests (dreys) in branches.
Attractive outdoor elements include:
- Overhanging trees close to roofs
- Thick hedges or climbing vines (ideal for dreys)
- Fruiting plants or flowering natives
Some possum species prefer higher elevation and dense foliage, like the Mountain Brushtail Possum, which is occasionally spotted on the urban fringe of Sydney.
5. Scent Trails and Territorial Marking
Once a possum claims your property as part of its territory, it will begin marking it — often with scent glands, urine, and scratch marks.
This behaviour not only signals other possums to stay away but can also reinforce the animal’s attachment to your property, making it harder to relocate. To understand more about this behaviour, visit Possum Territory and Scent Marking.
6. Shelter During Breeding Season
During mating and breeding periods, female possums actively search for safe nesting areas to raise their young. Your home’s ceiling void may offer an ideal environment for a family of possums.

Why Urban Possums Prefer Human Homes
Possums are incredibly resilient. Over the years, they’ve evolved to coexist with humans in urban areas — learning where to find food, shelter, and safety from predators. Our full breakdown of this adaptation can be found in Urban Adaptation of Possums.
Unfortunately, what may seem like harmless visits can turn into long-term habitation, resulting in damage, noise, and legal headaches if not managed correctly.
Preventing Possum Attraction
If you want to avoid possum activity around your home, take the following preventative measures:
- Harvest ripe fruit from trees regularly
- Secure bins and compost with tight-fitting lids
- Trim tree limbs away from the roof
- Install possum-proofing on roof entry points
- Avoid feeding wildlife (directly or indirectly)
