Watch Out for These 9 Annoying Australian Urban Pests


Even small changes in climate can impact certain species’ survival.

As the temperature increases, some pests find a comfortable habitat to nest and start spreading to urban regions. In fact, many urban pest species fare better with climatic warming.

Increased pests require proactive pest management; but first, you need to know what you’re looking for. While urban pests vary around the world, Australians face their fair share, including:

1. Roaches

Cockroaches are significant health threats because of the amount of parasites that they can carry.

These pests are known to carry Salmonella bacteria with them, along with various other types of viruses, fungi and moulds.

As if that – and their ick factor – don’t creep you out enough, roaches also produce allergens that can, in turn, lead to asthma.

2. Ants

Considered as minor pests in homes, gardens and other establishments all over the world, ants tend to form colonies in small spaces.

The insects then bring pathogens with them by feeding on decayed food and animal carcasses.

You can expect ants to be harmful pests in kitchens and hospitals, where they even feed on sterile packagings and wounds.

3. Termites

These pests form colonies and feed mainly on wood, which causes costly damages to buildings and any wooden structures inside.

The most common invasive termite species is Coptotermes formosanus, which originated in China and has been spreading to other countries ever since.

4. Mosquitoes

Aedes albopictus and Ae. aegypti flourish well in urban environments where still water is easily found in discarded containers around houses, factories and more.

These mosquito species are responsible for carrying viruses causing the dengue fever, Chikugunya, Zika and yellow fever. When climate warming occurs, these vectors can spread to places with higher altitudes.

5. Rodents

Wild rodents survive better in warm and wet environments, so it’s no surprise that they can sustain themselves much better with increasing temperatures.

These major urban pests are known to carry parasites and diseases. They can also cause a significant loss of food.

6. Bed bugs

While bed bugs do not transmit diseases, their bites can cause minor inflammations around the bite areas, creating an irritating itch that can last for a few days. These nocturnal pests take advantage of humans’ nighttime sleeping habits and the small spaces they can hide around the bedroom.

7. Mites

These tiny arachnids can be found in soil, water, plants and animals – it’s not uncommon to know them as parasites on plants and pets. Mites thrive in warm and humid environments, and the most well-known mite – the house dust mite – can be a major cause of asthma.

8. Spiders

While spiders do not transmit diseases, some species’ bites are painful and venomous.

When spiders are spotted around the house, you should clear them up as soon as possible as a prey reduction strategy so that bigger, more dangerous spider species such as white-tailed spiders will not be attracted into your home.

These bigger spiders will lead to more than just a common pest issue with its venomous bites.

9. Flies

Having flies in the house is more of a nuisance than a health concern, although they can still transmit diseases to humans.

Flies feed on most food sources, with decaying and faecal matters being the most worrying health concerns. When flies stop on your food after stopping on unhygienic substances, food-borne bacteria can lead to diseases.
