Cockroaches have been present on Earth for over 300 million years. They are the most common pest of dwelling plus food handling and storage establishment throughout Australia, contaminating both food and food handling equipment. Some species co-habit with humans in many other areas such as offices, factories, transport vessels, vehicles plus sewer systems, drains and composts used for the garden. Some pest species of cockroaches have contact with animal and human faeces as well as contaminated food, and they transfer these organisms both on their bodies and in their faeces onto the food which is being prepared for human consumption.

Cockroaches and Disease

Many human diseases have been found in and on the bodies of cockroaches. These diseases include organisms which cause food poisoning such as gastroenteritis, dysentery, hepatitis and tuberculosis.

Cockroach Food & Diet: What They Eat

The pest species of cockroaches eat a wide variety of foods so that most domestic and food handling establishments are attractive to them. Crumbs, dried liquids on bench tops and floor coverings, hair and even starchy bindings of books ensure their survival. While some species of cockroaches can fly, although not very well, most dispersal occurs through the transport of food, food cartons and other goods.

How To Get Rid Of Cockroaches – Prevention Tips 

Like most animals, cockroaches need food, water and shelter and these three requirements are present in most houses and buildings where humans live, work and play.
The following preventatives are recommended:

  • Eliminate all food and water sources. This is generally achieved by implementing clean-up procedures at the end of each day so that food is not available during the night when cockroaches are active. This procedure is particularly relevant in offices, factories and food handling establishments as well as domestic residences.
  • Store food in sealed containers or in refrigerators to reduce accessibility by cockroaches.
  • Keep garbage in sealed containers prior to collection.
  • Inspect all incoming containers and packaging from food stores prior to unwrapping within the residence or business.
  • Regularly inspect the motors of washing machines and refrigerators, plus the areas under and at the rear of all stoves, refrigerators and washing machines, as these provide cockroaches with shelter and warmth and sometimes moisture.
  • Monitor electrical equipment particularly microwave ovens, fax machines and computers, as these also provide shelter and warmth, particularly in winter months. This may also help to prevent expensive electrical repairs.
  • Use vacuum cleaners to remove food waste from floors and cupboards in kitchens as simply wiping these surfaces down will often result in leaving residues in cracks and crevices.
  • Fill all cracks and crevices in walls and cupboards to prevent cockroach access.
  • Inspect roof voids, as this can often locate populations of otherwise undetected Smoky-brown or American cockroaches.
