BROWN BANDED COCKROACH
The Brown Banded Cockroach is a small cockroach compared to other types at around the same size as German Cockroaches (13-16mm) and as the name suggests they have pronounced bands and colouration across the wings of the adults and bodies of the nymphs. Often mistaken for a German Cockroach due to its size similarities it can be easily distinguished by looking at a few characteristics. There is a large difference between the male and female with the females’ abdomen being distinctly larger than the male along with having much shorter wings than the male.
Looking closely at the wings, the Brown Banded cockroach has two sidebands with yellowish-brownish stripes, the pronotum has a translucent border with a dark bell-shaped pattern.
The Brown Banded Cockroach female lays an egg case around 5mm long and up to 20 eggs in each case. She prefers to lay her egg casings in aggregations and this species has been known to lay egg cases massed to the size of golf balls. Once hatched the nyphs will take around 60-120 days to develop thorugh 6-8 molts to reach adulthood. The adult Brownbanded Cockroach will live approximately 3-6 months depending on condtiions and each female will deposit betwen 6-13 egg cases producing between 100-260 offspring.
The Brown Banded Cockroach is primarily an indoor pest, unlike other cockroaches, it is found throughout homes and habitats including bedrooms, in furniture including under chairs and in lounge suites, behind pictures on the wall, underneath tables. Whereas the German Cockroach is usually restricted to food preparation areas where the humidity is high, the Brown Banded cockroach will be widely distributed throughout a home and prefers a less humid environment. It is commonly known as the ‘furniture’ cockroach for this reason. It prefers higher resting places and the female will generally lay her egg cases in the upper 2/3 of the walls. (Benson and Huber 1988).
The Brownbanded roach is mostly active at night in search of food and is an opportunistic feeder. This cockroach prefers food sources with high starch content and will attack wallpaper and book bindings.
