How Seasonal Changes Influence Rat Activity in Perth

As Perth’s seasons shift from dry summers to wet winters, local rat populations respond—and so should your rodent control strategy. Many homeowners only react to rats when they hear scratching in the ceiling or find droppings in the kitchen. However, understanding how seasonal changes influence rat behaviour can help you stay one step ahead of infestations all year long.

In this blog, we explain how each season impacts rodent movement and reproduction, and what you can do to protect your home during every phase of the year.

Summer: Searching for Water and Shelter

While most people associate rats with colder weather, summer in Perth presents its own challenges. Rats are highly active during hot months, but their focus shifts to finding water and shade. Garden taps, pet bowls, leaky pipes, and even dripping air conditioning units attract thirsty rodents.

Rats also seek cool, dark places—often inside sheds, under decking, or inside poorly ventilated roof spaces.

Summer Prevention Tips:

• Fix leaking outdoor taps and pipes

• Empty pet water bowls overnight

• Trim dense vegetation near the home

• Store pet food and grain in sealed containers

Autumn: Nesting and Stockpiling

As temperatures cool, rats begin to prepare for winter. This is prime nesting season, and they will look for warm, undisturbed spaces like roof voids and wall cavities. They also begin to stockpile food, which means they are more likely to explore pantries and rubbish areas.

Autumn Prevention Tips:

• Inspect your roof and seal entry points

• Remove clutter from sheds and garages

• Keep garbage tightly sealed

• Clear fallen fruits or bird seed from gardens

Winter: Moving Indoors

Winter is peak infestation time. Rats move indoors in search of warmth and steady food sources. Once inside, they breed and spread quickly. You may hear activity at night—scratching, chewing, or movement in ceilings and walls.

It’s during this season that rodent control Perth becomes most critical. Rats can cause electrical fires, structural damage, and serious hygiene concerns if not dealt with swiftly.

Winter Prevention Tips:

• Book a professional rodent inspection

• Monitor for droppings or chewed materials

• Keep food off counters and floors

• Clean under appliances regularly

Spring: The Breeding Boom

Spring marks a surge in rodent populations. Young rats born over winter begin to leave their nests and explore new territory. This increases the risk of rats moving between properties or into new homes altogether.

Spring Prevention Tips:

• Continue sealing gaps and cracks

• Maintain yard hygiene

• Repair damaged roofing or vents

• Use secure bins and compost with care
