Oriental Cockroach Biology

Adult oriental cockroaches grow up to 32 mm long and are shiny black to reddish brown in colour. One of the largest home infesting cockroach species, these roaches are thought to derive from Africa, not the Far East. Female oriental cockroaches lay roughly 16 eggs at a time, producing around eight ootheca (egg cases) during their lifespan. This results in around 128 offspring with an average incubation period of 60 days.

Oriental Cockroach Behaviour, Diet, Habitat and Life Cycle

Mainly an outdoor species, oriental cockroaches invade homes and businesses through gaps in doorways. They prefer to live in areas where the temperature sits somewhere between 68-84°F. Any temperature below 59°F means that this cockroach species is unable to produce egg cases to foster their young, Oriental cockroaches complete seven to 10 instars with this development process lasting around 589 days. The female oriental cockroach has an estimated adult lifespan of 180 days while for males; it’s roughly 160 days.

Starting life outdoors beneath rotting wood and mulch, this cockroach invades homes and businesses in search of warm and moist harbourage, water and food. You’ll find this cockroach within pipes, sewers and drains as well as beneath kitchen appliances and washing machines. Diet-wise, oriental cockroaches feed on decaying matter but they won’t travel far within your property without a reliable water source.

Wondering How To Get Rid Of Oriental Cockroaches?
