iStock 000003885766XSmallCockroaches are insects of the order Blattaria or Blattodea, of which about 30 species out of 4,500 total are associated with human habitats. About four species are well known as pests.

The most common varieties in Australia include the German, American and Oriental cockroaches. American cockroaches are large and black. German cockroaches are smaller and brown. Oriental cockroaches are medium sized and dark brown to black in colour.

The cockroach is believed to spread a range of disease-producing organisms to humans including salmonella, staphylococcus and streptococcus. Cockroaches prefer warm, humid conditions with a ready food source.

Like the household fly, the cockroach will eat virtually anything ranging from food spills on a kitchen floor to faecal matter. Ingested bacteria can survive in the cockroach's digestive system, sometimes for months or even years, and are passed in its droppings. Cockroaches will vomit and defaecate on food and it is thought that disease may be transmitted to humans when humans eat food contaminated by cockroaches.


Treatment of Cockroaches in and around the Home


  • Gel is applied as a crack-and crevise treatment to specific areas
    • includes such areas as wall corners, under sinks, behind kitchen appliances, around plumbing pipes and wall voids


The gel is designed to draw the cockroaches in to feed and the cockroach dies from:-

  • consumption of gel
  • dispersion of gel to another cockroach via contact
  • Coprophagy - a cockroach eats the faeces from the primary cockroach
  • Necrophagy - a cockroach eats another cockroach that died from ingesting the gel
  • Emetophagy - a cockroach devours regurgitant from the primary cockroach



Safety Measures

   We ensure the safety of the entire family, including your much loved pets



Cockroaches Shelter and Nest in Places such as:

  • Walls, ceilings and under walls
  • Behind or under cupboards, bathtubs and household appliances
  • Near hot water heaters
  • Behind boxes, machinery and furniture or in paper or cloth
  • In rubbish heaps, wood piles, thick vegetation or animal enclosures
  • In holes under buildings



How do I know I have a Cockroaches Infestation?

  • Cockroaches are nocturnal insects.  They prefer to live and feed in the dark so a cockroach seen during the day is a possible sign of a infestation.
  • They look for dark moist places to hide and breed and can be found behind refrigerators, sinks and stores, as well as under floor drains and inside of motors and major appliances.
  • Because they can flatten their bodies to fit into narrow areas, cockroaches may also be found hiding beneath rubber mats, behind wallpaper and within wall cracks.
  • Cockroach faeces will be visible during an infestation. Small roaches produce feces that resemble coffee grounds or black pepper, while larger roaches expel cylindrical droppings. The quantity of visible feces is oftentimes a good indicator of the level or duration of infestation.
  • Some species emit unpleasant smells. In the event of serious infestation, a strong oily or musty odor may be present. The bodies of dead cockroaches can also be found throughout the house. Oval-shaped egg cases, known as ootheca, are sometimes visible behind furniture and in other hidden locations, such as the spaces between books.


Ways to Prevent Cockroaches in the Home?

  • Ensure rubbish bins have tight-fitting lids and are regularly emptied
  • Keep your home and property clear of rubbish
  • Keep stacked materials such as wood and bricks at least 30cm above the ground to minimise hiding/nesting/thoroughfare of rats
  • Regularly clean out sheds, storage areas and dispose of unwanted items
  • Remove unwanted undergrowth-cut back grass, trees, bushes and creepers which may provide cover or access to the roof
  • Do not use open compost heaps
  • Leave out just enough pet food for pets to eat soon after it is placed there
