The Exterminators: Sydney’s First Line of Defence Against Pests
The Most Common Cockroaches in Sydney
German Cockroach
The German cockroach is the most problematic species found in kitchens and food areas. They reproduce extremely quickly and hide in tight, warm spaces such as behind fridges, dishwashers, and cupboards.
Appearance & Size:
- Light brown to tan in colour
- Two dark parallel stripes behind the head
- Small size: typically 10–15mm long
Because of their rapid breeding cycle, German cockroaches often require two treatments to fully eliminate the infestation. Missing even a small number can result in reinfestation within weeks.
American Cockroach
Large and fast-moving, American cockroaches are commonly found in sewers, basements, and commercial buildings. They can enter homes searching for food and moisture.
Appearance & Size:
- Reddish-brown with a yellow band behind the head
- One of the largest pest species
- Typically 30–50mm long

Oriental Cockroach
Often found in damp areas such as drains and under houses, Oriental cockroaches are known for their strong odour and preference for cool, moist environments.
Appearance & Size:
- Dark brown to almost black
- Shiny, smooth body
- Typically, 20–30mm long
- Slower moving compared to other species
Australian Cockroach
This species thrives outdoors but often enters homes, especially in warmer climates. They are attracted to lights and can infest roof voids, wall cavities, and gardens.
Appearance & Size:
- Brown in colour with distinctive yellow markings on the thorax and along the wing edges
- Very similar in appearance to the American cockroach but slightly smaller
- Fully winged and capable of flying
- Typically, 25–35mm long
Smoky Brown Cockroach
The Smoky Brown cockroach is common in warm, humid areas of Australia and is often found around homes with gardens, trees, and moisture sources.
Appearance & Size:
- Dark brown to almost black with a shiny, glossy appearance
- Uniform colour (no distinct markings like other species)
- Fully developed wings and capable of flying
- Typically, 30–40mm long
They are commonly found in roof voids, gutters, mulch, and outdoor areas, but can enter homes—especially at night when attracted to lights.
Our Cockroach Treatment Process
At The Exterminators, we don’t just spray and leave—we treat the entire infestation thoroughly.
1. Inspection & Access to Key Areas
We identify infestation hotspots and physically access critical areas. This includes pulling out fridges and dishwashers to treat warm zones around motors where cockroaches commonly hide and breed.
2. Targeted Spray Treatment
We apply professional-grade residual sprays to key surfaces, cracks, and crevices to eliminate active cockroaches.
3. Gel Bait Application
High-quality cockroach baits are strategically placed to target hidden populations and disrupt breeding cycles.
4. Dusting Treatment
We apply insecticidal dust into wall cavities, voids, and inaccessible areas for long-term protection.
This combined method—spray, bait, and dusting—ensures maximum effectiveness and long-lasting results.
