Rat Identification
In Australia, there are native and introduced rat species; Native Bush Rats, Water Rats and Swamp Rats are protected, which means you can't harm them.
The two common introduced rats are Brown Rats and Black Rats. Native bush rats have a tail shorter than their body length; bush rats vary in size and colouration, measuring 100 to 205 mm with a tail length of 100 to 195 mm.
It weighs an average of 125 grams and exhibits greyish or reddish-brown fur. round ears, and pink foot pads.
The bush rat has a distinct diet from other local rodents. In summer, it mainly eats fruit, arthropods, and seeds. In winter, it relies heavily on a specific type of cyperaceous plant.
When in the forest, it primarily feeds on fungi and fibrous plant material. Additionally, bush rats consume nectar without harming the blossoms, potentially assisting in pollination.
The Australian swamp rat is about 160 mm long, with a tail of 110 mm and weighs around 120 grams. It has a stout build, black-brown fur, and dark feet.
The underside is cream to brown, and it has small, mostly hidden ears. Its tail is dark grey, scaly, and sparsely furred. The swamp rat diet is plant-based, including reeds, seeds, and swamp grass stems.
In summer, they also eat more insects and fungi. In spring, seeds become a major part of their diet, likely due to their availability and benefits for breeding
Because of their shy natures and differing diets that are mainly vegetation, insects and fungi, the native rats are less likely to be near human dwellings and are less inclined to be attracted to rat baits
Rat Identification: Brown Rat vs The Black Rat
The Brown rat, scientifically named Rattus norvegicus, goes by various aliases, including street rat, sewer rat, wharf rat, Hanover rat, Norway rat, and Norwegian rat, and is typically grey-brown with a long tail and large ears.
They have blunt noses and are usually about 20cm long – not including the tail. But size isn’t everything; behaviour also plays a big part in identification.
Black rats, also known as ship rats or roof rats due to their preference for high places, differ slightly in appearance from brown ones. They're smaller (about 16cm), and have pointy noses and larger ears compared to body size.
But don't let appearances fool you: both species cause similar problems when they reside on your property.
Pet Rats
As long as they are contained, pet rats are truly delightful companions. Their charming personalities, inquisitive nature, and boundless energy make them wonderful additions to any household. These small, furry friends are not only highly intelligent but also incredibly affectionate, forming strong bonds with their human caregivers.
Watching them play and explore their surroundings is a joy in itself, and their gentle nature makes them perfect for cuddling and interacting with. Whether they're performing acrobatics, snuggling up for a nap, or nibbling on a treat, pet rats have a special way of brightening your day and bringing warmth and laughter to your life.
Common Rat Damage
Rats can be more than a mere annoyance; they can inflict serious damage to your possessions. From rats building nests to gnawing on structures and electrical wires to spreading diseases through their urine and droppings, rats present various threats.
Structural harm is often the most visible form of rat damage. Rats have strong teeth, which let them chew through wood or plastic.
Their need to continuously chew doesn't stop there. Rats also enjoy chewing on electric cables. This habit poses a significant fire risk.
Beyond physical destruction, another major concern is disease transmission because rats can carry harmful pathogens in their droppings and urine, emphasising why it's so crucial we control rat populations effectively.
Preventing Rat Infestations
It is important to eliminate as many things that attract rats as possible;
- Frequent Cleaning. Ensure all rubbish bins are securely fastened, and food is not left in the open. This means sealing up any rubbish bins and not leaving food out overnight.
- Maintain a clean environment. It is crucial because untidiness attracts rats. So, give that neglected garden shed a good clear-out. The less clutter they have to hide in, the better.
- Solid Barriers: Fine metal mesh can prevent rodents from entering through small openings.
To stop an infestation before it starts takes effort and vigilance - but remember: prevention is not always enough. You may need to enlist the help of a professional to install bait strategies.

Signs of a Rat Infestation
Rat identification starts with evidence they are in the area. You could see one or more of these tell tale signs;
- Gnaw marks, especially on food packaging or the structure of your property, can be clear indicators. You might also notice smudge marks as rats often leave dirty tracks along walls and floorboards.
- Droppings. Rats produce up to 40 droppings per night, and they're usually found in concentrated areas.
- Urine trails and smell. Rats are always urinating either as defecation or to communicate with other rats.
- Noises. Rats are nocturnal, so you'll likely hear scratching noises at night from roof crawl spaces, cavity walls or under floorboards.
If you spot these signs but aren't sure if it's a rat issue, ask for professional advice immediately - time is crucial. The faster we act to remove them, the better, preventing more damage and reducing health risks.
