German cockroaches can be a major problem in commercial kitchens, restaurants, pubs, cafes and in our homes as they are prolific breeders, and can live in refrigerators and in ovens as well as the smallest cracks and crevices. They are a relatively small cockroach, ranging from nymphs (young insects) the size of a pinhead to adults up to 15–25 mm long.

Australian, American and to a lesser degree the smoky brown cockroaches can be found throughout buildings. They are much larger than the German cockroach, up to 30–55 mm, and they have the ability to fly at night.

Cockroaches typically are nocturnal, if you’ve seen one, you probably haven’t seen them all. The few cockroaches you see by day means they were likely forced out by overcrowding; a possible sign of severe infestation.

Cockroaches have been implicated in the spread of over 30 diseases such as Salmonella, which is a major cause of food poisoning.

COCKROACH LIFE CYCLE

First, nymphs hatch from egg cases that the adult female cockroach deposits. Then, as the nymph grows, it sheds its “skin” or exoskeleton so it can get larger. Apparently, each nymphal stage is larger than the previous one. Consequently, an adult cockroach emerges after the last nymphal stage.

To illustrate, the figure shows a simplified image of the life cycle (egg stage, nymph stage and adult stage) of the German cockroach.

German Cockroach

With the exception of the female Oriental cockroach, the adults of these three cockroaches have well-developed wings. However, they almost never fly. Hence, movement by both the adults and the wingless nymphs is by walking or rapid running.

These three cockroaches can be distinguished by colour and size. For example, adult German cockroaches are tan to medium brown in color. They are fairly small in size that ranges 10-15 mm. On the other hand, adult American cockroaches are reddish brown in colour and large in size that could be 35-40 mm. Although, Adult Oriental cockroaches are rather fairly large in size that is around 26-30 mm and are shiny, dark brown or black in colour.

COCKROACH FEEDING HABITS

For instance, the German cockroach commonly occurs in kitchens. However, the American cockroach appears more often in food establishments. The Oriental cockroach, on the other hand, is usually associated with dampness around sinks or in basements.
