Winter Pests in Brisbane
Brisbane winters are mild and dry. Most insect activity eases, but rodents look for warm shelter and indoor cockroaches keep breeding.
Updated 20 September 2026
Rodents in roofs and walls
Cooler nights bring roof rats and mice into ceilings, wall cavities and sheds. Scratching at night is the most common sign.
Indoor pests keep going
German cockroaches breed year-round in warm kitchens, and silverfish remain active in humid roof voids and wardrobes.
What to do
- Seal roof and wall gaps.
- Trim vegetation back from the roof.
- Store food and pet food securely.
- Set traps at the first sign of rodents.

Pest information
Rats
Introduced rodents that live alongside people, nest in roofs, walls and gardens and gnaw through building materials and wiring. Roof rats are the most common household rat in many Australian cities.
Mice
Small, curious rodents that squeeze through tiny gaps, nest in walls, cupboards and appliances and breed quickly. The introduced house mouse causes most household problems.
Cockroaches
Fast, flat-bodied insects that hide in warm, damp gaps and come out at night to feed. A few introduced species cause most household problems in Australia.
Silverfish
Primitive, wingless insects with silvery scales that live in humid, undisturbed places and feed on starch, paper and glue. They damage books and fabrics but are harmless to health.
