Hearing strange noises in your roof, walls or ceiling at night can be unsettling, especially if you suspect rats may have entered your home.
Rats are one of the most common pest problems affecting Adelaide homes and businesses. Because rats are nocturnal, many homeowners first notice rodent activity through scratching, scurrying or gnawing sounds during the night.
If you’re hearing unusual noises around your property, understanding what rats sound like can help identify a potential rodent infestation early before serious damage occurs.
EcoPest Group provides professional rodent control Adelaide services across Adelaide and surrounding South Australian regions.
What Noise Does A Rat Make?
Rats are generally most active at night when homes are quiet. As rats move through roof voids, walls and ceilings searching for food and nesting materials, they can create a variety of noticeable sounds.
Common rat noises include:
- scratching
- scurrying
- gnawing
- squeaking
- hissing
- tapping sounds in ceilings or walls
If you regularly hear these noises, particularly at night, you may have rats living inside your roof or wall cavities.
Common Rat Noises In Adelaide Homes
Scurrying Sounds
Scurrying is one of the most common signs of rats in roof spaces and wall cavities.
You may hear:
- fast movement across ceilings
- scratching in walls
- running sounds in roof voids
- movement between rooms at night
These sounds usually occur as rats travel through the home searching for food and nesting areas.
Gnawing & Chewing Sounds
Rats constantly gnaw to keep their teeth worn down.
Rats may chew on:
- timber
- electrical wiring
- pipes
- insulation
- plasterboard
- stored materials
Gnawing noises are often heard inside walls, ceilings or roof spaces and may indicate active nesting behaviour.
Rodent chewing can also create serious fire risks if electrical wiring becomes damaged.
Squeaking & Hissing Sounds
Rats communicate with one another using:
- squeaks
- chirping sounds
- hissing noises
Hissing may occur when rats feel threatened or disturbed, while squeaking often occurs during communication between colony members.
Why Are Rats Active At Night?
Rats are nocturnal pests, meaning they are most active after dark when homes are quiet and human activity is reduced.
During the night, rats commonly:
- search for food
- collect nesting materials
- move between nesting areas
- explore roof cavities and wall spaces
Because of this, rodent noises are often more noticeable late at night or early in the morning.
Signs Of Rats In Your Home
Besides hearing noises, other common signs of rats include:
- rat droppings
- scratching in ceilings
- greasy rub marks along walls
- damaged food packaging
- gnawed wires or timber
- unpleasant odours
- nesting materials in roof spaces
If you notice these warning signs, it’s important to arrange professional rodent control before the infestation grows larger.
