Winter Pest Activity in Sydney
By Aries Pest Solutions · 11 February 2026

It is a common belief that pests vanish once the weather cools, and while activity does slow, plenty of pests simply move indoors where it is warm. A Sydney winter brings its own set of problems, and some of them are easy to miss.
Rodents head for the roof
Winter is prime time for rats and mice. As outdoor food and shelter become scarce, they move into roof voids and wall cavities where it is warm and dry. Scratching in the ceiling at night is the classic winter complaint, and because rodents breed year round, a couple of arrivals can become an infestation before spring.
Cockroaches retreat indoors
Cockroaches do not disappear in winter; they concentrate around the warm, humid parts of the home. Kitchens, bathrooms, laundries and the spaces behind appliances stay busy right through the cooler months.
Spiders find shelter
Many spiders move indoors seeking warmth, which is why you often spot huntsmen on the wall on a cold evening. They are harmless, but unwelcome.
Silverfish and stored product pests
The damp, still conditions in winter cupboards and roof spaces suit silverfish, which quietly damage books, documents and clothing while everyone is focused on staying warm.
Termites keep working
Subterranean termites are insulated within their galleries and the soil, so they remain active through a mild Sydney winter. Winter is actually a good time to book an inspection, as inspectors have clear access and it sets you up before the spring swarming season.
Protecting your home over winter
- Seal gaps and entry points before rodents move in
- Keep an ear out for roof activity at night
- Manage moisture in cupboards and subfloors
- Book a termite inspection while access is easy
Frequently Asked Questions
Should I bother with pest control in winter?
Yes. Winter is ideal for rodent proofing and termite inspections, and treating now gets you ahead of the spring surge.
Why can I hear scratching in the roof only in winter?
Rodents move into roof cavities for warmth as outdoor conditions turn, so activity becomes far more noticeable.
