Cockroaches are Common Australian Household Pests that are really disgusting and stubborn house guests, but there are steps you can take for prevention and control.


  • Types and Habits of Cockroaches

If you have cockroaches in your home, they are likely to be one of three species: the German cockroach, Australian cockroach, or American cockroach.

  • Prevention Tips for Cockroaches

If you want to prevent a cockroach infestation, focus on denying them food, water, and easy entrance.

You should clean up food spills and keep food tightly covered. Either cover your bins or empty them every day. Did you know that cockroaches use smell to find food? They do, so airtight containers are a must. You should also make sure there is no standing water in your home.

Any small openings can be entry points for cockroaches. They also like cracks and crevices inside the house. You can use caulk or spray foam insulation to fill spaces around under-sink plumbing, electrical outlets, doors, and windows.

Cockroaches like unfinished wood surfaces because they can deposit their eggs in the grain. Stain, varnish, or paint wood shelves and cabinets to seal them against roaches.


  • Control of Cockroaches

Can you attack a roach problem with do-it-yourself methods? Yes, but calling a professional exterminator is the best way to knock out a cockroach infestation quickly. It takes some expertise to know which products to use and where to use them most effectively.


There are a number of options that professionals may use. Baits are often quite effective. They kill the cockroach that eats them, then other roaches feed on its carcass and they die, too. Sprays and powders are other options that may be part of a multi-pronged approach.



Fleas are one of the renowned common bugs in Australia. If you have pets, you have probably had fleas. They’re a nuisance, but they can also transmit diseases, so it’s important to eradicate them when they infest your home.


  • Types and Habits of Fleas

Fleas live on the blood of animals. The larvae usually hide in crevices until they’re mature. They emerge when they’re ready to find a host. Fleas can transmit blood-borne diseases and parasites. They often infect dogs and cats with tapeworm, and they can transmit this to humans, too.


  • Prevention Tips for Fleas

The best way to prevent a flea infestation is to treat your pet. Your veterinarian can help you sort through your options and find the best preventive medication.

You should also vacuum often to collect any stray fleas or eggs that may have made their way into your home. Keeping your pet’s bedding clean is also a must. Try to find a pet bed that can be washed in hot water.


  • Control of Fleas

Eradicating fleas often means treating your pets, the interior of your home, and your yard. The interior of your house may need to be fumigated. You might also need to wash things like curtains, cushions, and human and animal bedding in the hottest water the fibres can take.

Your yard will probably need to be treated with insecticides as well. An insect growth regulator will keep the immature stages of the flea from developing into the biting adults.



Ticks are another renowned common household bugs Australia and one of the more troubling household pests since they can carry diseases that are quite harmful to people.


  • Types and Habits of Ticks

There are about 70 species of ticks in Australia, although some of them have limited ranges. The most common are the Paralysis tick and the brown dog tick. Ticks feed on the blood of animals, and they transmit diseases through their bites.

A couple of the more serious diseases they carry are Flinders Island Spotted Fever and Queensland Tick Typhus. Ticks typically crawl up vegetation and wait for a suitable host to pass by. When you or your pet brushes against this vegetation, the tick drops on.


  • Prevention Tips for Ticks

Your goal is to prevent a tick from ever making contact with you or your pet. The following steps can help.

  1. Trim grass, flowers, and shrubbery around the house and along walkways.
  2. Wear long-sleeved shirts, slacks, and boots when you’re in environments where there are likely to be ticks.
  3. Use a repellent on clothes and exposed skin surfaces.
  4. Treat your pets with approved tick-repellent medications.


  • Control of Ticks

Knocking down a tick infestation usually involves treatment of the yard with insecticides. A type called pyrethrum is often the treatment of choice of professionals.

Anything you do to decrease the moisture in your yard and increase the amount of sun that penetrates to the ground is also helpful. This includes things like removing dead leaves and grass, watering less, and mowing often.

If you live in an area that attracts bandicoots, keeping them off your property is a key strategy for tick control. Bandicoots are a common host for Paralysis ticks.

  1. Keep food in sealed containers.
  2. Keep rubbish bins covered with tight lids and areas around pet bowls and bird feeders free of spilled food.
  3. Avoid letting debris pile up outside where it can provide cover for rodents.
  4. Seal openings around pipes and cables with caulking or steel wool.
  5. Repair holes or gaps in the roof.
  6. Cover drains with metal screens.


  • Control of Mice and Rats

There are several methods of rodent control that professionals may recommend if you have an infestation of rats or mice. Taking steps to keep the rodents out by sealing all access points is the most permanent option.

Australian Household Pests

  • Types and Habits of Silverfish

There is only one common species of silverfish, but it is found throughout six continents. Silverfish are nocturnal and prefer damp places, so you may find them in basements and closets. These insects like starches and sugars. This means that they will eat books and papers, carpet and clothing, and sugar and coffee. They may also contaminate food.


  • Prevention Tips for Silverfish

The best way to prevent a silverfish infestation is to decrease the humidity in the areas where you find them. The first step is to make sure you don’t have plumbing leaks that are keeping the area perpetually damp.

You can also try to increase the air flow in damp locations and use a dehumidifier periodically to dry the space. Checking boxes of books or paper that you bring into your home is always a good idea, too. Empty the box outside and look for silverfish before you bring the items inside.


  • Control of Silverfish

Do you just see the occasional silverfish? If so, you can use a common household insecticide spray to kill them. You may also put bundles of clothes or papers in plastic bags and leave them in full sun for a couple of hours to kill the adult silverfish and their eggs.

You might want to call a professional if you have so many silverfish that they’re causing significant damage. The professionals will use sprays and foggers to treat the areas that the silverfish are calling home.

  • Prevention Tips for Spiders

You’re fighting a losing battle if you want to keep spiders completely out of your house or garden. They’re rather sneaky, and some of the most dangerous live in concealed burrows.

One thing you can do is strive to keep your home free of other types of insects. This removes a food source, so your house will be less tempting to spiders. You may also want to keep your outdoor spaces free from debris that would encourage spiders to move in.

Subterranean termites build their nests underground and send workers out to find wood. They’re the most common and most destructive type of termite that is found in homes.

The drywood and dampwood types live within the wood they’re consuming. Dampwood termites are only a minor nuisance since they will leave if you repair whatever is causing the wood to be wet.


  • Prevention Tips for Termites

When you consider how much damage termites can do, it’s worth taking the time for a few preventive steps.

  1. Eliminate water sources around your home. This includes leaking pipes and runoff.
  2. Remove lumber and firewood from around your house. It provides cover and nesting sites for termites.
  3. Vent crawlspaces and other areas under the floors. This makes them less attractive to subterranean termites.
  4. Use timber that has been treated to resist termites for your outdoor building projects.
  5. Extract stumps and dead trees from your grounds.
  6. Apply chemical barriers around your home during or after construction.


  • Control of Termites

What if the worst happens and your home becomes infested with termites? Don’t hesitate to call for professional extermination. The exterminator may use a combination of baits and chemical barriers to control the problem.

Bait stations are placed around your home to attract termites. The termite takes the bait back to the nest, and the bait kills the termites that eat it.  A chemical barrier is applied around the perimeter of your home. It kills the termites that are present and helps prevent re-infestation. The chemicals used are safe for pets and people.

The best way to prevent problems with wasp nests is to catch them early. Small nests are easier to remove, and they won’t have dangerously large numbers of wasps in them. Check in corners and under eaves for early signs of wasp activity.

Keep outdoor bins covered so the wasps won’t be attracted to them, and keep doors and windows closed or screened. If you have an ongoing problem with wasps building nests on your home, you can spray insecticide on the eaves and other places that wasps find attractive.

  • Control of Wasps

If you have a single wasp that’s trapped in the house, go ahead and use an insecticide spray to kill it. It won’t like this much, so be prepared to back away. If you need to eliminate an entire nest of wasps, call a professional. Professionals spray wasp nests to kill the inhabitants. You will need to leave the nest in place for a couple of days to make sure all the wasps are dead before you remove it.
