Common House Pests in Australia

Australia is a host to a myriad of pests which include common culprits such as cockroaches, spiders, and ants that often find their way into homes. These pests each bring about unique challenges for homeowners.

Common House Pests


Cockroaches are undoubtedly one of the most unpleasant household pests we can encounter in Australia. These insects, specifically the Australian, American and German cockroaches, have made themselves right at home here.

You might be amazed to learn that some species like the Australian cockroach can grow up to 10cm long! Did you know that these creepy crawlies even display certain social behaviours? Yes, they feel loneliness and surprisingly possess the ability to hear.

To keep these uninvited guests out of our homes completely requires effective pest management strategies using bug sprays or roach traps as well as professional extermination services when needed.


Across Australia, the sight of spiders is quite common. With over 4,000 species crawling around in our diverse habitat, a few are bound to find their way into homes. Among them, we often see White-tailed spiders foraging under bark and leaf litter or hiding indoors when the weather calls for it.

You might also spot Black house spiders hanging out in your windows or corners – these creepy arachnids are known pests across Australia and even New Zealand. A little larger than their black counterparts, Huntsman spiders can grow up to six inches! These venomous critters saddle us with bites if disturbed and leave unsightly cobwebs dangling from our ceilings too.

Let’s not forget about the Redback spider either; its presence always causes a stir due to its notorious reputation for danger in every bite.

But remember – though these common house pests do cause concern as they crawl across our households uninvited, there are effective pest control measures that can help keep them at bay!


Finding ants in your home can be an unwelcome surprise. These common house pests, including the notorious carpenter or sugar ants, populate Australia with over 1,000 different species.

Perth homeowners may often encounter coastal brown ants and white-footed house ants. Ants like these contribute significantly to insect infestations throughout the country due to their proficiency at building ant colonies and creating expansive ant trails.

The shiny black bodies of sugar and black house ants won’t just be roaming your property but also possibly causing significant damage if left unchecked. It’s essential for both pest inspectors and homeowners to implement effective ant control measures such as using ant baits or repellents to manage these mini intruders successfully.


Rodents, featuring prominently among common house pests in Australia, demand serious attention. Unveiling a shocking fact, our nation is home to over 60 native rodent species and three introduced vermin varieties.

From the common house mouse (Mus musculus), an invasive species introduced by European settlers, to feral rats and mice – each contributes significantly toward public health concerns due to their disease-spreading tendencies.

As these creatures can multiply rapidly given favourable conditions; swift measures for rodent control are imperative. On detecting signs of infestation such as gnaw marks or droppings, homeowners should resort either to natural remedies like rat traps or seek immediate assistance from professional pest control services for pest eradication.

Furthermore, implementing preventive steps including regular inspections and rodent proofing can nip the problem in its nascent stage itself.

Bed Bugs

Bed bugs have become a frequent uninvited guest in many Australian homes. These tiny pests, often found lurking in the corners of mattresses and bedding, can cause itchy skin and allergies due to their unexpected bites.

Confusingly similar to mosquito bites or rashes, identifying bed bug bites relies on noticing small bumps spread across the skin. As silent invaders of our dwellings, they’ve thrived substantially between 1999 and 2006 attaining higher infestation rates nationwide.

Proactive pest control measures can help cut down their numbers significantly while ensuring sweet dreams for all inhabitants free from unwanted nibbles!

How to Get Rid of Common House Pests

When it comes to tackling common house pests, there is a wide array of effective methods to keep in mind. Foremost among these is prevention, as ensuring that your home is clean and well-maintained can swiftly nip any potential infestations in the bud.

Moreover, homeowners can resort to natural remedies, such as vinegar or peppermint oil, which are environmentally friendly solutions known to repel a variety of pests. Nonetheless, if the infestation is extensive or recurring, professional pest control services can step in to provide comprehensive extermination, using their expertise and specialised tools to guarantee a pest-free home.

How to Get Rid of Common House Pests

Prevention methods

Keeping our homes pest-free requires a blend of prevention methods. Here’s how we can protect our property:

  1. Regular house inspection: Checking the entire house including hidden places, and sealing off potential entry points like holes and gaps, prevents pests from finding their way in.
  2. Outdoor maintenance: Screening low decks and trimming overhanging branches deters pests from coming close to the building.
  3. Window and door seals: Ensuring there are no cracks or gaps around windows and doors acts as an effective deterrent for creepy crawlies seeking shelter inside homes.
  4. Avoiding ceiling downlights with large gaps: This simple measure can greatly reduce the risk of infestation.
  5. Professional pest treatments: Enlisting the help of professionals for a comprehensive extermination not only eliminates existing vermin but also provides protection from future invaders.
  6. Outdoor insecticide application: Targeted use of insecticides around outdoor areas like foundations, woodpiles, and mulch heaps can keep pests like Australian cockroaches at bay.

Natural remedies

We highly recommend using natural remedies as a safe and eco-friendly solution to combat common house pests in Australia. These DIY solutions are cost-effective, widely available, and usually just involve items you already have at home! They also reduce our dependence on harmful chemicals that degrade our environment.

  1. Fill small Ziploc bags with peppercorns, eucalyptus leaves, cloves, bay leaves, and lavender to deter pests naturally. Poking holes in these bags allow the fragrance of these plants to permeate your home effectively.
  2. You can even create homemade traps for cockroaches and ants using simple ingredients like sugar and baking soda.
  3. Citrus peels or citrus-based cleaners discourage spiders – they hate the smell!
  4. Diatomaceous earth is an organic powder made from tiny fossilised aquatic organisms and works as a great insect killer.
  5. Vinegar is another household item that can scare away ants while cleaning surfaces in your house.
  6. Essential oils such as peppermint, cedarwood or lemongrass can repel various pests including rodents.

Professional pest control services

Professional pest control services are essential for effectively eliminating common house pests. These experts conduct thorough inspections to identify the pest species and assess the extent of the infestation.

Based on their findings, they develop tailored treatment plans using pesticides like insecticides and herbicides to eradicate pests. Hiring a professional pest control company is particularly crucial when dealing with resilient pests like spiders, as their expertise ensures a faster and more effective solution than DIY efforts or home remedies.

So, let the exterminators handle it and say goodbye to those uninvited house guests!

Protecting Your Property from Infestations

Keeping your home protected from infestations requires vigilance and an active effort to maintain proper sanitation. Regular cleaning and prompt disposal of food waste can eliminate the resources pests need to survive, reducing their attractiveness to your property. Moreover, sealing any entry points, such as cracks or gaps in walls, windows, and doors, forms a physical barrier that prevents pests from gaining access to your residence.

Regular inspections of your property, ideally by professionals, are also advisable to detect any early signs of pest activity and nip potential infestations in the bud.

Lastly, it is equally important to eliminate attractants like standing water or overgrown vegetation that may serve as breeding grounds or food sources, and therefore lure pests onto your premises. By adopting these preventive measures, you proactively create an environment that is inhospitable to common house pests, ensuring the comfort and safety of your home and its inhabitants.

Proper sanitation

Maintaining proper sanitation is essential for protecting your property from common house pests in Australia. By keeping your living spaces clean and free of food debris, you can minimise the risk of infestations.

Regularly sweeping and vacuuming floors, wiping down surfaces, and taking out the trash promptly are simple yet effective ways to prevent pests from finding a comfortable home in your house.

Additionally, make sure to store food in sealed containers and clean up spills or crumbs immediately. By practising good hygiene and cleaning practices, you can create an environment that is unwelcoming to pests and keep them at bay.

Sealing entry points

To prevent pests from entering your home, it’s crucial to seal off their entry points. Here are some effective ways to do so:

  1. Use weather stripping: Apply weather stripping around doors and windows to create a tight seal that pests can’t penetrate.
  2. Seal cracks and gaps: Inspect your home for any cracks or gaps in the walls, foundation, or floors. Fill them with sealants or caulk to eliminate potential entryways.
  3. Install wire mesh screens: Cover vents, chimneys, and other openings with wire mesh screens to keep pests out while allowing proper ventilation.
  4. Fix broken windows and screens: Replace damaged windows and screens promptly to avoid giving insects an easy route inside.
  5. Secure door sweeps: Install door sweeps at the bottom of exterior doors to block pests from crawling underneath.
  6. Check utility lines and pipes: Ensure that utility lines and pipes entering your home are properly sealed with durable materials to prevent pest intrusion.

Regular inspections

Regular inspections are crucial for protecting your property from infestations and ensuring its long-term preservation. By conducting regular termite inspections, you can catch infestations in their early stages, potentially saving thousands of dollars in repairs.

Not only that, but pest inspections can also help safeguard your investment and negotiate a fair price when buying or selling a property by identifying hidden or potential infestations.

Additionally, timber pest inspections are essential for detecting and preventing damage from pests other than termites, such as borers or wood decay fungi. By seeking regular termite inspections and working with professional pest control technicians who can perform annual inspections and create protection plans tailored to your property’s needs, you can maintain the value of your home while preventing costly damage caused by pests.

Removing attractants

To prevent infestations and keep your property pest-free, it is crucial to remove all sources of attractants. Here are some steps you can take:

  1. Keep your property clutter-free: Hoarding can attract unwanted pests to your property, so make sure to declutter regularly.
  2. Dispose of food scraps properly: Leaving food out around the property can be a major attractant for pests. Always clean up spills and crumbs immediately and store food in sealed containers.
  3. Properly dispose of garbage: Make sure to securely seal garbage bags and regularly take them out to prevent pests from being attracted to the smell.
  4. Maintain cleanliness: Rubbish and filth on the property can also be a magnet for pests. Regularly clean your property, especially areas prone to dirtiness.
  5. Seal off potential entry points: Regular inspections should be conducted to identify any cracks or gaps where pests can enter your property. Seal these entry points with caulk or mesh screens.
