Rodent Season in Melbourne: When Rodents Are Most Active & How to Keep Them Out

Rodents like rats and mice are a major pest issue for homes and businesses across Melbourne. They spread disease, damage property, and multiply quickly, so understanding when rodents are most active in Melbourne’s unique climate can help you stay ahead of infestations. In this article, we’ll cover when to be on high alert, the signs of a rodent problem, and the best strategies for effective rodent control in Melbourne.

When Are Rodents Most Active in Melbourne?

Melbourne's climate—with its cold winters and mild summers—makes it an ideal place for rodents to thrive year-round. However, their behaviour changes with the seasons.

Autumn & Winter (March–August): Prime Rodent Season

As temperatures drop, rats and mice begin seeking warmth and shelter indoors. Autumn is when we see the biggest spike in rodent activity across Melbourne homes. They sneak into roof cavities, walls, sheds, and garages—anywhere warm and hidden.

Spring (September–November): Nesting & Breeding

Rodents that settled inside during winter start to breed in spring. A single pair of rats can produce hundreds of offspring in a year, so spring is when infestations can grow rapidly if left unchecked.

Summer (December–February): Outdoor Activity Rises

During warmer months, rodent activity shifts outdoors, but infestations don’t necessarily go away. Rats may move to gardens, under decks, or into wall voids. They often return indoors if food or water becomes scarce.

Signs You Might Have a Rodent Problem

Droppings near food or in cupboards
Scratching sounds in the roof or walls, especially at night
Gnawed wires, wood, or packaging
Nesting materials (shredded paper, fabric, insulation)
Greasy marks along walls or floorboards
