Australia’s Most Common Pests

Australia is home to quite a large number of troublesome and dangerous pests. While the majority of insects, reptiles, and animals that require pest control here are fairly harmless, there are also some that are deadly.

It is true that Australia is home to several venomous spiders and a large percentage of the world’s most deadly snakes, however these insects and reptiles account for only a minuscule percentage of call outs to pest controllers in Brisbane. The actual majority of calls are taken for the more common and generally less dangerous bugs and animals such as possums, rats, mice, cockroaches, and ants.

This theme is congruent throughout the majority of Australia, not just in suburban SEQ. With Australia’s mix of nature, suburban, urban, commercial and industrial areas, pests here need removing across a variety of environments. Generally however it is the same sort of elements e.g. accessible foodstuffs, moist environments etc. that encourage unwanted nasties to take up residence in the first place. This is regardless of whether it is in a suburban dwelling, a restaurant, a commercial warehouse, or an office block.

We have put together a short list of the most common Australian critters for your reference below. These pests are listed in no particular order and the information given is purely for general knowledge. If you have a problem with any of the creatures listed below or even any that aren’t please get in contact with us to find out how we can help on 1300 442 978!


Spiders renowned for being ugly and intimidating not just in Australia but throughout the entire world. Many species are venomous however very few contain enough toxin to actually kill a fully grown human. Not a single human has died from a spider bite in Australia since 1979. This is largely due to the introduction of anti-venom. Despite this, spiders are still extremely common here and some can be a particular nuisance.Australian spider. Australia's most common pests

Many species weave their webs in the corners of buildings, in the eaves, air vents, and even between wall cracks. Some even go as far as webbing in your garden, across footpaths and between trees, making your residential dwelling look messy and unkempt.

This will stop the spiders entering the premises via them, and also stop them taking up residence there.

If there are no other insects for them to feed on spiders are less likely to stay.

In the garden, do away with sheltering sites like garden bags, firewood piles, and composite piles. Spiders love to hide behind objects such as these. Should a spider or even a family of spiders decide to build webs around your home, use a stick to knock them down immediately. This will encourage the spiders to move on to a new home somewhere else.

Bees or Wasps

Australian bees and wasps Australia's most common pestsWasps and bees can be a problem in the garden, and unfortunately for some in the walls of their home. This situation can be much worse than when they are outside. In some cases, wasps enter homes through open windows and build their nests. If they go unnoticed or left uncontrolled, wasps can build a large nest containing over 25,000 wasps. Given that they build these nests in wall cavities, lofts, and bushes, they pose an imminent danger should they feel threatened. A sting from a wasp or a bee can be a very painful experience and if you are allergic to stings, then a wasp or bee sting is potentially deadly to you.

Bees generally build their nests outside but when a nest is formed in a cavity of your home it can become a real problem. For this you need a professional bee removal expert to relocate the nest somewhere more suitable. DIY wasp extermination is more common however for large nests or in circumstances where there is a high risk it is also best to consult a wasp removal expert who can safely treat the area without risk or damage to the property.


Ants get into houses to search for food and when they do this, they can be a particular nuisance. Research points out that some species of ants carry diseases and you and your family can be affected. Some ants also bite, which can be a painful experience, especially if you are allergic to the sting. If you see small piles of earth around window sills, bathrooms, kitchen benches, holes in soil or at the base of exterior walls to your home or commercial premises, it is likely that the place is presently infested with ants.

Next, clear up any sticky residues from food on counter tops, as ants are attracted to these. Finally, cover up any foodstuff which may be a source of food for the ants. If the plague of ants is getting out of control it is advisable to use other methods to treat them. Insecticides and gel baiting will work the best. Natural methods such as using borax and vinegar sprays can also be effective, however if it is a bad infestation, other forms of treatment are most likely going to be necessary to get rid of them.

Rats and Mice

Rats and mice are dangerous to humans because they can spread deadly diseases, cause considerable damage, and contaminate food.

Australian cockroaches Australia's most common pestsCockroaches prefer living in warm homes, wall cavities, and around damp spaces such as kitchens and bathrooms. They most often come out after dark to search for food, however you will see them during the day sometimes too. Research shows that cockroaches carry a lot of diseases that can compromise your well-being, especially if you consume too much of what they have walked on or eaten. To make matters worse, the Australian climate provides a perfect breeding ground for cockroaches. These intolerable insects are associated with a number of health risks. It’s believed that they can put you at risk of Dysentery and Gastroenteritis, and Salmonella; all potentially deadly diseases that will make you very sick, even if they don’t kill you. Increases in childhood asthma and eczema have also been associated with cockroach droppings.

There are many different ways to eliminate cockroaches from your home. Some of these include using cockroach spray, bait traps, and bombs. Home sprays are not advisable in all conditions due to the fact that they can be harmful to children and pets, and the effect will be minimal. If cockroaches in your home are out of control, it’s advisable that you liaise with a professional company to help with their elimination. Most of these companies understand the habits of each cockroach species and will use this concept to come up with an effective control program for your home or office. Once all cockroaches are gone, you may want to prevent them from coming back. The most effective way to achieve this is to deny them easy access to water, food, and shelter, and regular pest control. Make sure crumbs and other food particles don’t accumulate in and around the counter-tops, bins, and cabinets.


Australia is synonymous with snakes. While some may not be dangerous, others are deadly and can claim a life with just a single strike. Snakes prefer forested or sheltered grassland areas and if you happen to live near such in a Australian snake Australia's most common pestsrural setting, then you likely have encountering some before. They may move into your house because of flooding, looking for food or shelter, or other reasons. While some are harmless and even friendly, most can cause injuries if they feel threatened.

Contact a local pest control company who will come and examine the snake to check whether it’s venomous or not. They will be trained on how to handle snakes and will catch them without putting you, your family and pets at risk of an attack. Like many other pests, snakes too can be prevented from entering homes or buildings. One way to do this is to avoid planting tall-growing plants too close to the house. Another way is to remove ground-level water sources. You should also make sure that other pests such as rats and mice are completely eliminated because these will attract snakes into your home.
