Australia is home to a wide variety of insects and animals, some of which can be a nuisance to homeowners. One of the most common pests found in Australian homes is the carpet beetle. Despite their name, these beetles don't just eat carpets; they also feed on a range of materials, including animal hair, fur, wool, and clothes. In addition to carpet beetles, clothes moths and silverfish are also known to infest carpets and cause damage. While less common, carpet pythons, which are native to Australia, can also fall prey to larger predators such as crocodiles, birds of prey, and dingoes.

What You'll Learn

Carpet beetles
The Australian carpet beetle, also known as *Anthrenocerus australis*, is a native species to Australia and is one of the most prevalent and well-researched species within the *Anthrenocerus* genus. This species is identified by its dark brown to black oval-shaped body, growing to approximately 2.2-2.5mm in length. The adult beetles have distinct white bands across their bodies and are attracted to light sources, often found on window sills. The larvae of this species are covered in hairs and can cause allergic reactions in some individuals.
The varied carpet beetle, or Anthrenus verbasci*, is a multicoloured species found in various parts of the world, including Europe, Asia, and Australia. This species is slightly larger than the Australian carpet beetle, reaching up to 3mm in length. The black carpet beetle, or Attagenus unicolor*, is the largest of the three species, measuring up to 5mm in length, and is predominantly found in North America.
While carpet beetles can be a nuisance, they do not bite, and they are not known to carry or transmit diseases. However, the hairs from the larvae can cause skin irritation and allergic reactions in some individuals.

Carpet moths
To prevent a carpet moth infestation, regular cleaning andvacuuming are recommended, especially in the areas that moths are most likely to inhabit, such as under furniture and in dark corners. It is also important to seal entry points, such as cracks, doors, and windows, to minimise the chance of moths entering your home.
If you have a carpet moth infestation, it is recommended that you call a professional to eradicate them. While vacuuming can help to reduce the number of moths, it is unlikely to completely eradicate them, and their short life cycles and high reproduction rates mean that they can quickly re-infest a home.

Silverfish
To prevent and control silverfish infestations, it is important to address moisture issues in the home. Sealing cracks, closing doors, and maintaining fly screens can help prevent silverfish from entering. Regular cleaning and vacuuming, especially in areas where silverfish are commonly found, is also important. Essential oils such as lavender and tea tree oil can be used as repellents, and camphor, mothballs, or pest strips can be placed in storage areas.
If you discover a silverfish infestation, it is crucial to take action immediately. This includes systematically cleaning all surfaces, washing clothing and bedding, shampooing carpets, and vacuuming upholstered furniture. Diatomaceous earth, a fine powder that cuts into silverfish, can be sprinkled on floors and left for 24 hours before vacuuming.
While silverfish can be a nuisance and cause damage to household items, they may also play a role in maintaining insect equilibrium in the home. They eat predatory arthropods, including spiders, and even their own dead. Therefore, it is not recommended to kill silverfish if only a small number are spotted.

Birds of prey
In Australia, various bird of prey species can be found, including the Australian wedge-tailed eagle, which is the largest bird of prey on the continent. With a wingspan of up to 2.7 meters, this majestic bird soars over open landscapes and preys on rabbits, hares, and other small mammals. Another iconic bird of prey in Australia is the white-bellied sea eagle, often spotted soaring over coastal areas and feeding on fish, birds, and carrion.
The peregrine falcon, known for its speed and agility in flight, is also prevalent in Australia. It can dive at incredible speeds to capture prey, such as birds and small mammals. The brown falcon, on the other hand, is a more versatile hunter, feeding on insects, small reptiles, and mammals, and even scavenging for food.
While not as well-known as the previous species, the square-tailed kite deserves a mention. This bird of prey is a skilled aerial hunter, specialising in catching small mammals and birds on the ground. It has exceptional agility and precision in capturing its prey. Lastly, the Australian kestrel, a small but mighty bird of prey, feeds primarily on insects but will also take small lizards, frogs, and mammals when the opportunity arises.

Dingoes
While dingoes are apex predators, they must compete with other predators for food and be cautious of larger animals that may attack them. For example, wedge-tailed eagles can spot and kill dingoes, and crocodiles can be ambush predators. Dingoes are also at risk from venomous snakes, although their quick reflexes help them avoid most snake bites. Humans pose the greatest threat to dingoes, as they are often seen as pests and eradicated through trapping, hunting, and poisoning.

Frequently asked questions
There are a few insects and pests that are known to eat carpets in Australia. The most common ones are carpet beetles, carpet moths, and silverfish.
You may notice damaged materials or sand-like larval droppings, which indicate the presence of carpet beetles. The adult beetles are small, oval-shaped, and dark brown to black in colour. They are often found near windows, fresh flowers, or bird nests.
To prevent carpet beetle infestations, you can purchase carpets that have been treated with insect-resistant chemicals. Seal entry points, regularly clean and vacuum carpets, control moisture, and carefully inspect flowers and bird nests before bringing them inside. To control an existing infestation, an integrated approach combining various management strategies (chemical, physical, and cultural) is recommended.
