Identifying Common Australian Pests: A Visual Guide
Australia's diverse climate and environment make it a haven for a variety of pests. Identifying these unwanted guests is the first crucial step in protecting your home and garden from potential damage and health risks. This guide will help you recognise common Australian pests, providing you with the knowledge to take appropriate action.
Cockroaches
Cockroaches are among the most common and resilient pests found in Australian homes. They thrive in warm, humid environments and are attracted to food scraps and moisture. Identifying the specific type of cockroach is important as it can influence the best course of treatment. Pestcontrolexterminator can assist with identifying and managing cockroach infestations.
Common Cockroach Species in Australia
German Cockroach (Blattella germanica): Small, light brown, with two dark stripes behind the head. They prefer warm, humid places like kitchens and bathrooms and reproduce quickly.
American Cockroach (Periplaneta americana): Large, reddish-brown, and capable of flight. They are often found in sewers, drains, and around the perimeter of buildings.
Australian Cockroach (Periplaneta australasiae): Similar to the American cockroach but with yellow markings on its thorax. They are commonly found outdoors but may enter homes in search of food and water.
Oriental Cockroach (Blatta orientalis): Dark brown or black, and often found in damp, cool places like basements and drains. They are sometimes referred to as "waterbugs."
Identifying Cockroach Infestations
Sightings: Spotting live cockroaches, especially during the day, is a strong indicator of an infestation.
Droppings: Small, dark, cylindrical droppings resembling coffee grounds or black pepper.
Smear Marks: Brown, irregular smear marks on surfaces where cockroaches travel.
Odor: A musty or oily odour in heavily infested areas.
Egg Casings (Oothecae): Small, brown, bean-shaped capsules that contain cockroach eggs.
Termites
Termites are destructive pests that feed on cellulose, the main component of wood. They can cause significant structural damage to buildings if left unchecked. Early detection is crucial to minimise the extent of the damage. If you suspect a termite problem, it's best to contact our services immediately.
Types of Termites in Australia
Subterranean Termites: The most common and destructive type, living in underground colonies and building mud tubes to reach food sources.
Drywood Termites: Live within the wood they infest and do not require contact with the soil. They are less common but can still cause significant damage.
Dampwood Termites: Prefer damp or decaying wood and are often found in areas with high moisture levels.
Identifying Termite Infestations
Mud Tubes: Earthen tubes built by subterranean termites to travel between their colony and food source. These are often found on walls, foundations, or in crawl spaces.
Damaged Wood: Wood that sounds hollow when tapped or is easily probed with a screwdriver. Look for blistering or sunken areas on wooden surfaces.
Swarmers: Winged termites that emerge from their colony to mate and establish new colonies. This usually occurs in spring or summer.
Termite Droppings (Frass): Small, dry pellets that resemble sawdust, often found near termite entry points.
Rodents (Rats and Mice)
Rats and mice are common household pests that can contaminate food, spread diseases, and cause damage to property. They are attracted to food, water, and shelter. Understanding the differences between rats and mice is important for effective control.
Common Rodent Species in Australia
House Mouse (Mus musculus): Small, slender, with a pointed nose and large ears. They are typically grey or brown and can squeeze through very small openings.
Brown Rat (Rattus norvegicus): Also known as the Norway rat, they are large, heavy-bodied, with a blunt nose and small ears. They are typically brown or grey and prefer to live in burrows.
Black Rat (Rattus rattus): Also known as the roof rat, they are slender, with a pointed nose and large ears. They are typically black or dark brown and are excellent climbers.
Identifying Rodent Infestations
Droppings: Small, dark, pellet-shaped droppings found along walls, in cupboards, or near food sources.
Gnawing: Damage to food packaging, electrical wires, or wooden structures.
Nesting Materials: Shredded paper, fabric, or other soft materials used to build nests.
Tracks: Footprints or tail marks in dust or dirt.
Urine Odor: A strong, ammonia-like odour in infested areas.
Sightings: Seeing live rodents, especially during the day, indicates a significant infestation.
Spiders
While most spiders are harmless, some species in Australia are venomous and can pose a threat to humans. Identifying dangerous spiders is crucial for safety. If you're concerned about spiders around your home, learn more about Pestcontrolexterminator and our spider control services.

White-tailed Spider (Lampona cylindrata and Lampona murina): Slender, grey spiders with a distinctive white spot on their abdomen. Their bite can cause pain, redness, and swelling.
Huntsman Spider (Family Sparassidae): Large, hairy spiders that are often found indoors. They are generally harmless but can deliver a painful bite if provoked.
Identifying Spider Infestations
Webs: Spider webs in corners, along walls, or in gardens.
Sightings: Seeing live spiders, especially in large numbers.
Egg Sacs: Small, silken sacs containing spider eggs.
Ants
Ants are social insects that live in colonies. They are attracted to food and water and can become a nuisance in homes and gardens. While most ants are harmless, some species can bite or sting. Understanding ant behaviour is key to effective control. You can find frequently asked questions about ant control on our website.
Common Ant Species in Australia
Argentine Ant (Linepithema humile): Small, brown ants that form large colonies and are highly invasive. They are attracted to sweet foods and are difficult to control.
Coastal Brown Ant (Pheidole megacephala): Small, brown ants with large heads. They are commonly found in coastal areas and are attracted to a variety of foods.

Bull Ant (Myrmecia spp.): Large, aggressive ants with a painful sting. They are found throughout Australia and can be a nuisance in gardens.
Identifying Ant Infestations
Trails: Lines of ants marching along walls, floors, or sidewalks.
Nests: Ant nests in lawns, gardens, or inside walls.
Food Sources: Ants foraging around food spills or crumbs.
Mosquitoes
Mosquitoes are flying insects that feed on blood. They are a nuisance and can transmit diseases such as Ross River virus and dengue fever. Controlling mosquito populations is important for public health.
Common Mosquito Species in Australia
Aedes aegypti: Known for transmitting dengue fever, Zika virus, and chikungunya. They are active during the day and prefer to breed in artificial containers.
Culex annulirostris: A common mosquito species that transmits Ross River virus and Barmah Forest virus. They are active at dusk and dawn and breed in stagnant water.
Anopheles farauti: A mosquito species that can transmit malaria. They are found in northern Australia and breed in freshwater swamps and lagoons.
Identifying Mosquito Infestations
