As temperatures drop in Victoria, rodents seek warmth in suburban roof spaces. Discover how to inspect entry points and prevent gnawing damage.

1. Scratching Sounds in Roof Cavities

Nocturnal scratching, scampering, or scuttling above bedroom ceilings is the clearest indicator of roof rats nesting in insulation batts.

2. Sealing Weep Holes and Cable Penetrations

Mice can squeeze through gaps as small as 6mm. Fitting stainless steel weep hole protectors and mesh stops entry cold.

3. Tamper-Proof Perimeter Bait Stations

Lockable bait boxes placed along external perimeter fences reduce rodent pressure before they ever reach exterior walls.
