There are two main species of cockroaches, the Oriental and the German.
The Oriental is 25–33mm long, shiny, dark brown and nearly black. The female’s wings are short, but the male's wings cover two-thirds of the abdomen.
The German is light brown in colour with two dark stripes running lengthwise just below the insect’s head. The female is darker than the male and both are fully winged.
Cockroaches are often seen running quickly across surfaces, particularly in the kitchen or any area where food is stored.
