Cockroaches, also commonly known as cockroaches, are omnivores that live in cracks, crevices, pipes and air ducts during the day. They eat everything of organic origin, from food and moist tissue to leather. They like warmth and moisture and often appear in groups, in which they orient themselves with the help of scents. They prefer to infest locations and rooms in which there are always large accumulations of food residues, e.g. kitchens, bakeries, food storage areas, etc. Cockroaches can transmit various infectious diseases that could lead to hospitalisation, including anthrax, tuberculosis, salmonella, fungal diseases and many more. Cockroaches can be introduced via the transportation of goods on all routes, as well as via personal luggage. Apart from this, cockroaches are highly resistant and occur all year round. There are no direct breeding sites, as the female carries the egg packages (oothecae) around with her and only drops them shortly before they hatch. Four species have become established here:
