Cockroaches

What are they?

Cockroaches are insects of the order Blattaria or Blattodea, of which about 30 species out of 4,500 total are associated with human habitations. About four species are well known as pests. Cockroaches live in a wide range of environments around the world. Pest species of cockroaches adapt readily to a variety of environments, but prefer warm conditions found within buildings. Many tropical species prefer even warmer environments and do not fare well in the average household. Cockroaches are mainly nocturnal and will run away when exposed to light. A peculiar exception is the Asian Cockroach, which is attracted to light.

Cockroaches are generally rather large insects. Most species are about the size of a thumbnail, but several species are bigger. The world's heaviest cockroach is the Australian Giant Burrowing Cockroach, which can reach 9 centimetres (3.5 in) in length and weigh more than 30 grams. Cockroaches have a broad, flattened body and a relatively small head. They are generalized insects, with few special adaptations, and may be among the most primitive living insects. The mouth is on the underside of the head and include chewing mandibles. They have large eyes and long flexible antennae.

The first pair of wings are tough and protective, lying as a shield on top of the hind wings. All four wings have branching longitudinal veins, and multiple cross-veins. The legs are sturdy with five claws each.

Why is it considered a pest?

Cockroaches are one of the most common household pests in Australia. They have no set patterns in their feeding and travelling patterns. They feed on anything from human waste to dead human skin cells and are attracted to proteins, sugars, starches, meats and dairy. Any discarded food. They passively transport microbes on their body surfaces including those that are potentially dangerous to humans and can then spread those germs through their droppings, regurgitation and crawling all over our personal items, including utensils used for preparing foods. The bacteria that they spread are linked to food poisoning, dysentery and gastroenteritis. Cockroaches can also trigger allergic reactions like asthma, bronchitis and dermatitis.

Where can it be found in Australia?

Cockroaches can be found across Australia; however, it depends on the species of ant and the habitat in which they preside in. All cockroaches are susceptible to Hovex solutions. 

Where it’s usually found in the home?

Cockroaches crave warmth, food sources, moisture and hiding spaces. They are generally found in the kitchen, behind and under stoves, refrigerators and other kitchen appliances. Behind washing machines and near hot water systems. They are also nocturnal, so are generally seen at night.
