Identifying Common Insects
Insects are among the most prevalent pests in Australia. From cockroaches scurrying across floors to ants marching through kitchens, these tiny invaders can cause significant problems. Understanding their characteristics and habits is crucial for effective management.
Cockroaches
Cockroaches are adaptable and resilient insects that thrive in various environments. Several species are common in Australia:
German Cockroach (Blattella germanica): Small (1-2 cm), light brown with two dark stripes on their pronotum (the shield-like plate behind the head). They prefer warm, humid environments like kitchens and bathrooms.
American Cockroach (Periplaneta americana): Large (3-4 cm), reddish-brown with a yellowish figure-eight pattern on their pronotum. They are often found in sewers, drains, and basements.
Australian Cockroach (Periplaneta australasiae): Similar to American cockroaches but slightly smaller and with yellow stripes on their sides. They prefer warmer climates and are often found outdoors.
Oriental Cockroach (Blatta orientalis): Dark brown to black, about 2.5 cm long. They prefer cool, damp places like basements and drains.
Cockroaches are nocturnal and scavengers, feeding on almost anything. They can contaminate food, spread diseases, and trigger allergies. If you suspect a cockroach infestation, it's important to address it promptly. You might consider exploring our services for cockroach control.
Ants
Ants are social insects that live in colonies. They are attracted to food and water sources and can quickly become a nuisance in homes and gardens. Common ant species in Australia include:
Argentine Ant (Linepithema humile): Small (2-3 mm), light to dark brown. They are highly adaptable and can form large colonies, making them difficult to control.
Coastal Brown Ant (Pheidole megacephala): Small (2-3 mm), brown with disproportionately large heads in the soldier caste. They are aggressive and can displace native ant species.
Black House Ant (Ochetellus glaber): Small (2-3 mm), shiny black. They are attracted to sweet foods and often nest in wall cavities and under floors.
Sugar Ant (Camponotus spp.): Larger (5-15 mm), black or brown with a distinctive sweet odour when crushed. They are attracted to sugary substances and often forage indoors.
Ant control involves identifying the species, locating the nest, and using appropriate baits or insecticides. For persistent ant problems, professional assistance may be required.
Termites
Termites are wood-destroying insects that can cause significant structural damage to buildings. They feed on cellulose, the main component of wood, and can tunnel through timber undetected for years. Common termite species in Australia include:
Subterranean Termites (Coptotermes spp.): The most destructive termite species in Australia. They live in underground colonies and build mud tubes to access wood.
Drywood Termites (Cryptotermes spp.): They live entirely within the wood they infest and do not require contact with the soil.
Dampwood Termites (Porotermes spp.): They infest damp or decaying wood and are often found in areas with high moisture levels.
Signs of termite infestation include mud tubes, hollow-sounding wood, and the presence of winged termites (alates). Regular inspections and preventative measures are essential to protect your property from termite damage. If you suspect termites, it's crucial to contact a professional pest control company for a thorough inspection and treatment plan.

Identifying Common Rodents
Rodents, such as rats and mice, are common pests in urban and rural areas. They can contaminate food, spread diseases, and damage property.
Rats
Rats are larger than mice and have a more robust build. Common rat species in Australia include:
Brown Rat (Rattus norvegicus): Also known as the Norway rat or sewer rat. They are large (up to 40 cm including the tail), brown with a blunt nose and small ears. They are often found in sewers, drains, and basements.
Black Rat (Rattus rattus): Also known as the roof rat or ship rat. They are smaller than brown rats (up to 25 cm including the tail), black or dark brown with a pointed nose and large ears. They are agile climbers and often nest in roofs and trees.
Rats are nocturnal and omnivorous, feeding on a wide variety of foods. They can enter buildings through small openings and cause significant damage by gnawing on wires, pipes, and other materials.
Mice
Mice are smaller than rats and have a more slender build. The most common mouse species in Australia is:
House Mouse (Mus musculus): Small (7-10 cm including the tail), greyish-brown with a pointed nose and large ears. They are highly adaptable and can thrive in a variety of environments.
Mice are nocturnal and omnivorous, feeding on grains, seeds, and other foods. They can contaminate food, spread diseases, and damage property by gnawing and nesting.
Signs of rodent infestation include droppings, gnaw marks, tracks, and the presence of nests. Rodent control involves eliminating food and water sources, sealing entry points, and using traps or baits. For severe infestations, professional pest control services may be necessary.
Identifying Common Spiders
Australia is home to many spider species, some of which are venomous and potentially dangerous. Identifying common spiders can help you take appropriate precautions.
Redback Spider (Latrodectus hasseltii): Black with a distinctive red stripe on its abdomen (females only). They are found throughout Australia and are known for their painful bite.
Funnel-web Spider (Atrax robustus): Large, black or dark brown with a shiny carapace. They are found in eastern Australia and are highly venomous.
White-tailed Spider (Lampona cylindrata): Greyish or brownish with a white patch on its abdomen. They are found throughout Australia and are known for their painful bite, which can sometimes cause ulceration.
Huntsman Spider (Delena cancerides): Large, hairy spiders with long legs. They are found throughout Australia and are generally harmless, although their size can be intimidating.
Most spider bites are not serious, but it's important to seek medical attention if you suspect you have been bitten by a venomous spider. Keeping your home clean and tidy can help reduce spider populations.
Identifying Common Birds and Other Wildlife Pests
Birds and other wildlife can sometimes become pests, causing damage to property and creating a nuisance.
Pigeons (Columba livia): Common in urban areas, they can damage buildings with their droppings and spread diseases.
Indian Myna Birds (Acridotheres tristis): An introduced species that is highly adaptable and aggressive. They can displace native birds and cause damage to crops.
Possums (Trichosurus vulpecula): Native to Australia, they can damage gardens, roofs, and other property.
Snakes: While most snakes are harmless, some venomous species can pose a threat to humans and pets. It's important to be aware of the snake species in your area and take precautions to avoid encounters.
Controlling bird and wildlife pests can be challenging and may require specialised techniques. It's important to consult with a professional pest control company or wildlife expert for advice.
Signs of Infestation and Damage
Recognising the signs of pest infestation is crucial for early detection and effective control. Common signs include:
Droppings: Rodent droppings, cockroach droppings, or bird droppings.
Gnaw marks: Damage to wood, wires, or other materials caused by rodents or termites.
Tracks: Footprints or trails left by pests.
Nests: Nests built by rodents, birds, or insects.
Unusual odours: Musty or unpleasant odours that may indicate the presence of pests.
Damage to plants: Damage to leaves, stems, or roots caused by insects or other pests.
- Sightings: Seeing live or dead pests in your home or garden.
If you notice any of these signs, it's important to take action promptly to prevent the infestation from worsening. Contacting Pestcontrolexterminator for a professional inspection is always a good first step.
