Cockroaches are insects of the order Blattodea, which interestingly, also includes termites.

They are not a well liked species, with flattened bodies that allow them to live and breed in the most unlikely and smallest of places, usually in the kitchen and food preparation areas as they seek out water and kitchen scraps.

The majority of cockroaches found in Melbourne are native species and common types include the:

  • German cockroach – Blatella germanica
  • American Cockroach – Periplaneta americana
  • Oriental Cockroach – Blatta orientalis
  • Australian Cockroach – Periplaneta australasiae
  • Common Shining Cockroach – Native Bush species

Cockroaches mostly prefer warm environments and dark places except for the Asian cockroach which appeal for light spaces.

They are primarily scavengers, feeding on dead animals and plant matter and they are nocturnal unless there are very high population infestation levels which means they may be seen during daylight hours. Some cockroach pests are beneficial to our environment because they recycle organic decaying matter.

Cockroaches, similarly to ants, produce an invisible trail chemical which contains pheromones. The trail chemical is used for cockroach swarming and mating. It is used by other cockroaches to trace the source of food as well as finding the other cockroach hideouts for mating.

Cockroaches make a chirping, clicking or hissing sound. They breathe through their trachea which is attached to the spiracles. Cockroaches can survive or live for a month without food and up to 45 minutes without air.

Cockroaches are dangerous to human health, often responsible for food poisoning, as they live and breed in the same areas where food is stored and prepared. They can cause allergic reactions in humans such as asthma which is caused by an allergy protein called tropomyosin.

Prevention of Cockroaches

Cockroaches are known to cause wreak havoc at home. Control methods include:

  • Patching up vents, crevices and cracks on walls where cockroaches hide. Before sealing the hideouts, you should do a cockroach inspection to identify most areas infested by the pest.
  • Residential buildings are ideal and conducive environments for pest breeding. Most homes provide cockroaches with warmth, nesting cavities, food and water. Preventive measures include keeping water and food in sealed containers, proper kitchen cleaning, repairing leaking taps and pipes and using garbage cans that have tight lids.
  • Application of powder repellents that are harmless to humans but vulnerable to cockroaches and bedbugs is another control solution. This is an effective way of cockroach treatment or cockroach control.

If you are concerned about cockroaches, a specialist professional pest controller will apply pesticides to eliminate the infestation and is the best way to ensure effective and long-term cockroach control services.
