Knowing a Pest’s History and Remedies: An Overview on Rats

Australia is famous for having diverse wildlife, from creatures on land to the sea. Anything from kangaroos to a wide range of snakes makes it a zoologist’s playground. However, this diversity in species isn’t always appealing, especially to homeowners.

Rats are common household pests in Australia, with over 60 native species showcasing diverse wildlife even with these animals. Although these tiny rodents may seem harmless at first glance, just a handful of them can pose dangerous health risks. In this article, we’ll give you an overview of Australia’s rat species and how you can successfully defend your home from them.

Tracing Rats’ Ancestry in Australia

Rat species in Asia arrived almost five million years ago, with rat species believed to have come to Australia by boat or clinging into drifting foliage. This makes rats the first-ever colonisers of Australia, even before humans arrived on land.

While this ancient species of rats arrived by chance or instinct, the spread of black and brown rats was thanks to European settlers. They landed on Australian soil by ships and continued to spread with the First Fleet, which arrived in 1788.

Understanding Rats’ Attraction to Residential Properties

Although rats have no trouble living in the wild, they’re mostly drawn to settlements and urban settings due to various reasons. Like any animal, rats have basic needs to ensure their survival. A source of food, water, and shelter is enough to make them attracted to human homes full of stored food and protection from harsh weather conditions. For these reasons, rats are typically attracted to residential spaces.

Although all Australian homes can typically provide food, water, and shelter to rats, there are some specific features these pests look for. Listed below are some potential red flags that your home can look appealing to rats:

  • Poor Waste Disposal: Rats want to find a home that can easily be a source of food. Since they aren’t picky eaters, even chipping away at building material, rats prefer homes with poor waste disposal. If they can easily get into your trash cans indoors or outdoors, they’ll most likely find your home a viable breeding ground.
  • Compromised Pipes: Besides having a food source, rats need a steady water supply. Leaky pipes can give rats ample water sources for their needs. This is why it’s vital to check your plumbing systems, especially your drainage pipes, to treat them for leaks or cracks.

Keeping Rats Away from Your Property

Rats can hide through narrow crevices and tight spaces within your property. For this reason, you need to be smart about luring them out and keeping them off your home. The simplest solution is to use snap or lure traps.

Simple live and snap traps lure rats with bait and capture them alive. This allows you to remove them from your property once the traps trigger safely. However, keep in mind that snap traps have a high chance of killing rats. While killing pests isn’t illegal, keep in mind that proper disposal is necessary to prevent you from dealing directly with animal corpses.

It’s usually easier to attract adult rats due to their size. For this reason, young, smaller rats are much trickier to spot, trap, and keep off from your property. If you can’t handle these pests yourself, you may want to consult with professional pest control services.


Although it’s advantageous to have considerable knowledge of your pest situation, it’s crucial to determine the gravity of the problem. If you’re not making any progress in successfully removing pests from your property, it’s time to call in professionals to do their job.
