Cockroaches

There are only 6 families of cockroaches found worldwide, consisting of 4000 species. Australia has representatives of 5 of these families but with only 428 species present. Half of the cockroaches in Australia can be found in the Blattidae family which includes both the native and introduced species.

Cockroaches in Australia are widespread and adapted to both wet and dry environments. Most species are nocturnal and ground dwelling and are usually found hiding during the day in crevices, under bark, rocks or logs and in burrows.

Some species invade human dwellings and are considered pests. These cockroaches can be carriers of various diseases because they are commonly found near waste deposits or in the kitchen, where food is present. Restaurants may also experience cockroach infestations.

Cockroaches can measure over one inch in length, with tropical species tending to be larger than those found in other climates. Cockroaches have six legs, two antennae and wings. However, a number of winged cockroaches are not particularly adept at flying. Cockroaches emit unpleasant odors and may also produce sound.

The most frequently treated species are American Australian Smokey Browns and Asian Cockroaches and German Cockroaches (mostly found in commercial building rarely in houses in the Top End) as well there are many other species that are regularly found in this area. Cockroach control may involve the use of sprays, dusts and baits - in all situations good-housekeeping practices are essential. An ongoing program and regular follow up services is essential.
