There colour is dark Brown nearly Black and are 20 – 24 mm long and life span i 4 – 5 months.
Areas of habitat; normally this would be the sewers and within the wall cavities of buildings only emerging when conditions change; Rising water and over population.
Control measures carried out currently using insecticide gel causing a cascading effect, this means after a cockroach has died it becomes food for others and so on working around 5 times exponentially however due to the abundance of these insects control can be short lived.
