German Cockroaches

10-15mm in length, dark orange/brown in colour 

They are only found internally amongst electrical appliances and warm environments. Cracks, crevices and kitchen door hinges supply great breeding areas for this species and they are usually found in large numbers. German Cockroaches are the WORST of them all as they breed a lot faster and are the hardest to control.

These are commonly mistaken as German Cockroaches but they are only found in low numbers (eg. 1 or 2) and usually fly in from the outside neighbouring trees.

28-44mm in length.  Dark orange in colour.

Found in roof voids, subfloors, drains and sewers.

Habits & Biology

Cockroaches are scavengers and will eat almost anything - dead animals, vegetable materials, cardboards, fabrics, glue, hair and book bindings.  The introduced domestic species appear to eat almost anything.

Cockroaches congregate in roof-voids, beneath concrete slab patios and paths, in crevices, under bark, rocks or logs, in common household kitchen appliances and cupboards.

Cockroaches that breed in your household appliances , kitchen cupboards, restaurants ,commercial kitchens and their production machines are called German Cockroaches.  These cockroaches pose a health hazard and should be treated by a Pest Professional as soon as possible.  See below for Link to your Local Pest Professional to help you with your cockroach problems.

The Cockroach is also one of the hardiest insects on the planet, capable of living for a month without food.

It is suggested that cockroaches will "inherit the earth" if humanity destroys itself in a nuclear war.

BEWARE - A person who is allergic to consuming shellfish is also likely to have an allergy to eating cockroaches.
