Why Rodent Activity Peaks in Winter Across Sydney & Brisbane
Even in Australia's mild winters, rodents seek shelter, food, and warmth inside homes from June through August. A single mouse can squeeze through a gap of just 6mm — making older Federation homes in Sydney and Queensland timber homes in Brisbane particularly vulnerable. Once inside, a pair of mice can produce over 60 offspring per year.
5 Warning Signs to Watch For
1. Droppings: Dark, pellet-shaped mouse droppings (3–6mm) or larger rat droppings (12–18mm) near food sources, inside cabinets, or along skirting boards indicate active infestation.
2. Gnaw Marks: Fresh gnaw marks on wood, plastic food containers, electrical wiring (a fire hazard), and plumbing pipes indicate ongoing rodent activity. Older marks fade to grey.
3. Nesting Materials: Rodents shred paper, insulation, and fabric to build nests. Check roof voids, wall cavities, under kitchen appliances, and in stored boxes.
4. Scratching Sounds at Night: Scurrying, scratching, or squeaking inside walls, ceilings, or the subfloor after dark strongly indicates rodent activity. Rats are most active in the first few hours after sunset.
5. Smear Marks and Tracks: Rodents have oily fur and follow fixed pathways, leaving dark grease marks along walls and baseboards. Flour or talcum powder sprinkled along suspected runways will reveal footprints overnight.
