How to Identify American Cockroach
Size
35–40 mm adult body length — Melbourne's largest common cockroach
Colour
Reddish-brown with a yellow or pale band behind the head
Behaviour
Can fly short distances in warm weather; attracted to lights; nocturnal; long-lived (1–2 years)

Sewers, stormwater drains, damp basements, subfloors, commercial buildings
Look-Alikes & Confusion Notes
Sometimes confused with Australian cockroaches. American cockroaches are slightly larger with a full yellow band behind the head, whereas Australian cockroaches have yellow margins on the thorax and wing edges.
Risk & Urgency
Moderate. American cockroaches carry bacteria and contaminate surfaces but are less prolific breeders than German cockroaches. Their presence usually indicates a drainage or moisture issue that needs addressing.
Where Found in Melbourne
American cockroaches are common in Melbourne's older suburbs with ageing sewer systems. They are frequently found in commercial kitchens, hospitals, and any building with floor drains or basement areas connected to the stormwater system.
What to Do Now
Check for broken drain covers, seal around pipes, and reduce moisture in subfloor areas. A single cockroach may indicate a larger population in your drains. T47 Pest Control provides perimeter barrier sprays and drain treatments to stop entry.
Frequently Asked Questions
- Why do American cockroaches come inside?
- American cockroaches typically live in sewers and drains. They enter homes through broken drain seals, gaps around pipes, and under doors — especially during wet weather or when drains are disturbed. They are attracted to warmth, moisture, and food.
- Can American cockroaches fly?
- Yes, American cockroaches can fly short distances, particularly in warm, humid conditions. Indoor flights are usually gliding rather than sustained flying. They are more likely to fly outdoors on warm evenings.
