Rats & Mice in Perth
Hearing scratching in your ceiling or finding droppings around the house? Rats and mice can remain hidden in roofs, walls and storage areas. Learn how to recognise the warning signs, identify possible entry points and make your property less attractive to rodents.
Common signs of rats and mice
Rodents can move through concealed spaces without being seen. These clues may indicate activity in or around your home.
Rodent droppings
Small droppings appearing in cupboards, pantries, roof spaces or along regular movement routes.
Scratching noises
Movement, scratching or scurrying sounds coming from ceilings, walls and other enclosed areas.
Gnaw marks
Chewed packaging, timber, stored items or other materials around the property.
Nesting material
Shredded paper, fabric, cardboard or insulation gathered in sheltered locations.
Tracks and runways
Marks, disturbed dust or repeated movement along walls, edges and sheltered pathways.
Rodent sightings
Seeing rats or mice indoors or repeatedly around outdoor structures and storage areas.
Worth noting: Scratching noises alone do not confirm rodents, but repeated noises alongside droppings or gnaw marks warrant further investigation.
Where do rats and mice hide?
Rodents prefer sheltered areas where they can remain relatively undisturbed. They may use hidden routes through a property while searching for food, water and nesting sites.
Check for access points. Gaps around roofs, doors, plumbing and vents may allow rodents to enter the building.
Roof spaces and ceilings
Quiet, concealed areas that can provide shelter and nesting opportunities.
Wall cavities
Protected spaces where rodents may travel between different parts of a property.
Kitchens and pantries
Cupboards, spaces behind appliances and other areas close to accessible food.
Garages and storage
Stored goods, cardboard boxes and low-traffic areas offering shelter.
Sheds and outdoor structures
External buildings, garden areas and sheltered spaces near food or waste.
Building entry points
Roof and eave gaps, service penetrations, damaged vents and external openings.
What attracts rodents to a property?
Rats and mice often look for the same essentials: food, water and a protected place to shelter.
Accessible food
Pantry products, pet food, fallen fruit, spilled food and unsecured rubbish can attract rodents.
Water sources
Leaking taps, pet bowls, outdoor water sources and damp areas may provide access to moisture.
Shelter and access
Roof gaps, storage clutter, dense vegetation and concealed building spaces can offer protection and access.
Rats vs mice: What's the difference?
Both can leave droppings, gnaw marks and signs of nesting, but their size and movement patterns may differ. Identification should consider several clues together.
Rats
- Generally larger-bodied
- Usually larger droppings
- May leave noticeable gnaw marks
- May use roof spaces and sheltered routes
Mice
- Generally smaller-bodied
- Typically smaller droppings
- Can use very small openings
- May be active around cupboards and storage
Identification tip: Droppings or scratching sounds on their own may not be enough to determine whether rats or mice are present.
How to reduce rat and mouse activity
Reducing access to food, water and shelter can help discourage rodents. Prevention works best alongside suitable professional control when activity is established.

Rats & Mice in Perth: FAQs
Quick answers about rodent activity, identification and prevention.
How do I know if I have rats or mice?
Common signs include droppings, scratching sounds, gnawing, nesting material and sightings. Several signs together can help identify the type of activity.
Can rats or mice live in my roof?
Yes. Roof and ceiling spaces can provide sheltered movement routes and nesting areas for rodents.
How are rodents entering my house?
Possible entry points include gaps around roofs, doors, vents, pipes and other openings. An inspection can help identify likely access.
Should I seal every gap immediately?
Entry-point maintenance is important, but an active opening should be assessed before it is sealed so rodents are not trapped inside.
Are rodent droppings safe to clean?
Rodent droppings can present health risks. Keep children and pets away, avoid sweeping or vacuuming dry droppings, and follow appropriate hygiene and cleaning guidance. Seek professional advice if the contamination is extensive.
When should I book rodent treatment?
Repeated sightings, fresh droppings, persistent noises or gnaw damage are good reasons to seek an assessment.
