Latin: Blatta orientalis.

The Oriental cockroach is not as common as the German cockroach. It is shiny black and is up to 2.5 cm long. Elytrons are almost entirely missing in the females, but they cover part of the males’ abdomen. The Oriental cockroach cannot fly. It climbs poorly and is mostly found on the floor and often in the boiler room or basement. The preferred temperature is from 20 to 29 ° C. If there is a shortage of drinking water it will, however, seek out cooler places with temperatures down to 12 ° C. The Oriental cockroach egg capsule contains about 15 eggs. The egg capsule is discarded after a few days, in a dark, protected place and a few months later the offspring appears. This must be taken into account when it comes to the extermination of the Oriental cockroach. It means that there may be newly hatched insects up to three months after the last adult cockroach is exterminated. At temperatures around 25 ° C it takes six months from hatching to maturity. For the extermination, poison with long durability or repeated treatments should be used until it is estimated that the offspring hatched from the capsules are also exterminated.
