Repeated activity
If the same pest keeps returning after cleaning or simple control measures, there may be harbourage, entry or a colony that has not been addressed.

Rats in Roof Cavities
Scratching, movement at night, droppings and gnawing in a roof cavity commonly indicate rodent activity, but the long-term solution depends on both population control and access management.

WHAT MATTERS
What to know about rats in roof cavities
Good pest decisions start with the right identification and an understanding of how the activity fits the property. These are the practical points we consider before recommending treatment or further investigation.
- Roof access can occur through gaps, damaged eaves, service penetrations and overhanging vegetation.
- Rodents can contaminate insulation and damage stored items or wiring.
- Control without addressing major entry routes can allow new rodents to replace those removed.
Goliath approach
We focus on the source of the activity, the property conditions and a treatment plan that matches the pest rather than relying on generic advice or unnecessary chemical use.

When professional help is useful
Unclear source
When the activity appears in several rooms or shared areas, inspection can help identify how the pest is moving through the property.
Higher-risk areas
Kitchens, commercial sites, roof voids, termite-risk areas and shared buildings often benefit from a structured professional plan.
COMMON QUESTIONS
Questions about rats in roof cavities
Why do I hear rats mostly at night?
Rats are mainly nocturnal, so movement often becomes more noticeable when the building is quiet.
Should roof entry points be sealed immediately?
Exclusion is important, but timing matters so animals are not inadvertently trapped inside.
