At Pestmac Pest Control Solutions, we understand that living along the East Coast of Australia means encountering a diverse range of pests, including the Coastal Brown Cockroach (Periplaneta australasiae). Understanding this familiar intruder can help you manage your home environment effectively.

Identification of the Australian Coastal Brown Cockroach
The Australian Coastal Brown Cockroach is easily recognised by its glossy brown colour and elongated body, typically measuring about 3 to 4 cm in length. With long antennae and wings, they can often be seen scurrying around kitchens, bathrooms, and other areas where food and moisture are abundant.
Habitat and Behaviour
These Australian Coastal Brown Cockroaches thrive in warm, humid conditions, making Australia’s East Coast an ideal habitat. They are primarily nocturnal, preferring to stay hidden during the day and emerging at night to forage for food. Coastal Brown Cockroaches are often found in dark, damp spaces, such as under sinks, inside cabinets, and outdoors in leaf litter or mulch.
Health Risks
While Coastal Brown Cockroaches are not known to spread diseases directly, they can carry allergens and bacteria that may contribute to health issues, particularly for individuals with asthma or allergies. Their droppings and shed skin can exacerbate these conditions, making it crucial to keep your living spaces clean.
Prevention and Control
To reduce the likelihood of an infestation, consider these preventive measures:
Maintain Cleanliness: Regularly clean kitchen counters and dining areas to eliminate food residues that attract cockroaches.
Seal Entry Points: Inspect and seal any cracks or gaps around windows, doors, and pipes to prevent these pests from entering your home.
Manage Moisture: Fix leaks and utilise dehumidifiers in damp areas to create an environment less conducive to cockroaches.
Seek Professional Help: If you suspect an infestation, contact Pestmac Pest Control Solutions for an expert assessment and effective treatment options.
