Cockroaches are adaptable, fast-breeding scavengers that will eat anything that humans do and quite a bit more including faecal matter and fermenting garbage. They are nocturnal at home in a dark, warm humid place including under the sink, in dishwashers, behind heating equipment, behind wallpaper, in kitchen cupboards and drawers, and in cracks and crevices.

Cockroaches can grow from a whopping 120mm to a tiny 10 mm. In Australia, we have around 400 cockroach species although only about 6 are considered household pests. These include:

  • German Cockroach – Blatella Germanica
  • American Cockroach – Periplaneta Americana
  • Oriental Cockroach – Blatta Orientalis
  • Australian Cockroach Periplaneta Australasiae
  • Brown-banded Cockroach – Supella Longipalpa
  • Smokey-brown Cockroach – Periplaneta Fuliginosa

Control Tips


There are things that the homeowner can do to reduce cockroach infestations and increase the effectiveness and longevity of ARK Pest control methods.

Why do I need cockroach control?

  • Cockroaches spread a range of diseases including Salmonella, Staphylococcus, Streptococcus, and Polio Virus. They can be suspected carriers of Typhoid Fever, Gastroenteritis, Dysentery, Giardia, Listeriosis and Campylobacteriosis.
  • They can be responsible for asthmatic reactions and cockroach “skin” or moult can cause allergic reactions like skin rashes, watery eyes, congested nasal passages and sneezing.
  • They produce odorous secretions and can affect the flavour of food.
  • Cockroaches are rapid breeders! A female German cockroach can produce 200 to 300 offspring a year.
  • Potentially, one German and her offspring can produce up to 300,000 roaches a year.
