How to Get Rid of Possums in Sydney

Getting rid of a possum is not about killing it, because that is against the law in New South Wales. What actually ends the problem is a two-part job: persuade the animal to leave the roof, usually with a one-way door that lets it out but not back in, then seal every gap so no possum can ever move in again. Anything that skips the sealing only clears the void for the next animal to find.

The line worth drawing early is between reducing sightings and solving the cause. Bright lights, radios and repellents may push a possum to a quieter corner of the roof for a while, but they leave the entry points open, so the relief lasts days. A lawful catch and release within 50 metres paired with proper proofing removes the animal and closes the door behind it, which is the only combination that keeps the roof empty. Our possum removal service is built around exactly that method, and the steps below explain how it comes together.

A possum settles in your roof for two reasons: it is dry and safe, and there is easy food nearby. You cannot change the first, so the job is to remove the second and take away the easy path in. Start with the trees. Overhanging branches are a highway straight onto the roof, so cutting them back a couple of metres from the eaves forces a possum to work much harder to reach the gap it has been using.

Then deal with the food. Fruit left rotting under a tree, pet bowls sitting out overnight, and open compost all tell a possum the property is worth staying near. Bringing pet food in after dark, picking up fallen fruit and securing the compost bin lowers the reward without harming the animal, which is the only approach the law allows. None of this evicts a possum already in the roof on its own, but it makes your home far less appealing than the neighbours' once it has been moved out and the gaps are shut, so the void stays empty rather than filling with the next arrival.

A licensed technician solves the root cause by working with the law rather than around it. The visit starts with an inspection that maps every entry point and checks whether a female has young inside, because the timing of the eviction depends on it. Where young are present, the work waits until they can travel with the mother so none are left behind.

The eviction itself is gentle. A one-way door is fitted over the main entry so the possum leaves at dusk to feed and finds it cannot get back, or the animal is trapped and released within 50 metres as the rules require. Once the void is confirmed empty, every gap along the roofline is sealed with timber, mesh and capping matched to the building, and a nest box is often mounted in a nearby tree so the possum keeps its territory without keeping your roof. That combination of lawful removal and thorough proofing is what our possum removal team delivers, and it is the only approach that stops the cycle rather than pausing it.

Call a licensed technician the moment you are sure a possum is in the roof, rather than waiting to see if it moves on. It rarely does, and every week it stays adds droppings, noise and the risk of chewed wiring. If you can hear young, if the animal has been there long enough to leave a strong smell, or if the entry points are on a steep or two-storey roof you cannot safely reach, professional help is the sensible first call rather than the last resort.

You should also call before touching a trap or blocking a gap, because getting either wrong can break the law or seal an animal in to die. A technician handles the eviction, the release and the proofing as one lawful job, so you are not left guessing about the rules.
