What's different around Auburn
The Duck River corridor
Cumberland City Council calls the Duck River the main tributary of the Parramatta River. About 4.5km of its middle reach runs through Cumberland, taking in the Auburn Botanic Gardens, and the catchment around it is highly urbanised. Water, food and shelter this close together suit rats, mice and mosquitoes.
Mosquitoes by the river
NSW Health traps mosquitoes on the Duck River, and on 3 April 2025 its testing found Stratford virus in a catch from Granville. That virus isn't notifiable in NSW, and a result in a trap isn't a human case. It's still a fair reminder to cover up at dusk.
Possums in a built-up suburb
Cumberland's backyard guide says a tree hollow can take up to 100 years to form, and that losing habitat has pushed many possums into the roofs and walls of houses. They're protected in NSW, so the fix is proofing the roof, never poison.
Rodent control in Auburn starts with the food
Cumberland City Council asks people not to feed pest animals or leave food scraps and pet food lying around. That one habit does a lot of the work on rats and mice too. Keep bins shut, bring pet food in at night and clear clutter away from fences and walls.
If something's moving in the ceiling, work out what it is before anyone quotes. Scratching and gnawing at night points to rats or mice, while heavier thumps usually mean a possum. NSW Government guidance suggests sprinkling flour near the entry point, then checking the footprints.
Rats become a job for a pest business when the droppings, gnaw marks or noise keep coming back. Ask them to show you where the rats are getting in, because closing those gaps is what stops the next lot.
Renting in Auburn: who sorts it out?
Generally, NSW landlords are responsible for pests at the start of a tenancy, and tenants for pests that arrive later because of how the place is kept, such as rubbish attracting cockroaches, ants or mice. If pests came in another way, say through a hole in the wall, the tenant may not be responsible.
Tell your agent in writing as soon as you spot them. Still stuck? NSW Fair Trading runs a dispute resolution service.
What you can do, and what to hand over
You can
- Keep bins shut and pet food inside.
- Empty water from pot plates, buckets and blocked gutters every week.
- Photograph droppings, gnaw marks or a nest from a safe distance.
- Tell your agent or strata manager early if you're renting or in a unit block.
Leave to a pest business
- Finding how rats or mice are getting in, and closing it off.
- Treating cockroaches in kitchens and bathrooms.
- Wasp nests. Cumberland's guide warns that trying to remove one yourself can lead to injury.
- Possums in the roof, by a handler with a NSW catch and release licence.

Sort the food and water first, because any treatment has a harder time while the rats are still being fed. If they're still around a fortnight later, tell us what you've seen and your postcode.
