Hearing scratching, scurrying or thumping noises in your roof or walls at night can be stressful for many Adelaide homeowners.
In most cases, these noises are caused by:
- rats
- mice
- possums
- birds
- bats
- other roof pests
Although some noises may simply come from household plumbing or loose roofing materials, persistent scratching noises often indicate pest activity inside roof cavities, ceilings or wall spaces.

Why Are Roof Noises More Noticeable At Night?
Many roof pests are nocturnal, meaning they are most active during the night when homes are quiet.
During the day:
- household activity masks noise
- televisions and appliances create background sound
- pests are often sleeping or hiding
At night, scratching and movement inside ceilings or walls becomes much easier to hear.
Could The Noise Be Something Other Than Pests?
Not every roof noise is caused by animals.
Some noises may come from:
- loose pipes
- roofing movement
- electrical appliances
- air conditioning systems
- ceiling panels
- plumbing issues
One way to help identify the difference is consistency:
- household noises are usually repetitive and predictable
- animal noises tend to sound random and irregular
If the sounds involve movement, scratching or changing locations, pest activity is more likely.
