Rodent-Proofing Your Sydney Home Before Winter Hits
As temperatures drop, rats and mice move indoors. Here's the autumn checklist that keeps them out for good.
Why autumn matters
By April, Sydney nights drop into single digits and rats start scouting for warm nesting spots — roof voids, wall cavities, garages and sub-floor areas. The work you do now prevents an infestation in June.
The 20-minute exclusion checklist
- Walk the perimeter and seal any gap larger than a 5c coin (rats squeeze through 12 mm)
- Fit brush strips to the bottom of garage and external doors
- Check weep holes in brickwork — install stainless steel mesh covers
- Cut back tree branches within 1 metre of the roofline
- Move firewood and compost bins away from the house
- Secure pet food and birdseed in sealed metal containers
Inside the house
Listen for scratching in the ceiling at dusk and look for droppings (rice-sized for mice, raisin-sized for rats) along skirting boards and inside the pantry. If you find evidence, act within days — a single pregnant rat can produce 60 offspring in a year.
Bait stations vs traps
Snap traps work for small mouse problems. For rats, lockable external bait stations are safer and more effective — they keep baits away from children and pets while targeting the rodents at their entry points.
