Nosocomial infections have always played an important role in medical facilities and continue to cause serious problems for many patients. Hospital infections can have various causes. The ability of pests to act as vectors is often underestimated.

Rodents, cockroaches and flying insects are just a few examples of pests that carry a significant number of microorganisms on their bodies and can transport these into sometimes hygienically sensitive areas. When walking over contaminated surfaces, bacteria, viruses, fungi and parasites adhere to their bodies and are thus passed on. It is important to note that pests do not differentiate between boiler rooms, waste areas, cable ducts or operating theaters. Their habitat constantly varies according to hiding places and food supply. In their search for food, they pass through several areas, some of which are heavily contaminated.

Due to this fact, the issue of MRSA and ESBL is increasingly becoming the focus of pest control. Due to the vehicle function of pests, in particular cockroaches, flies and rodents, these harmful germs can also enter areas that have already been disinfected and pose a non-negligible risk to patients and staff.
