House rats (Rattus rattus L.) living in residential buildings in Magdeburg [Hausrattennachweise (Rattus rattus L.) in bewohnten Wohnhäusern in Magdeburg]

Storehouses and mills in the Magdeburg region are known to be infested with black (ore house) rats. In residential buildings, however, house rats (Rattus rattus L.) have not been detected for at least 20 years. Therefore, it was of much interest for the expert to note that this rat species had been seen in two occupied residential buildings (a refurbished old building and a terraced house). It has been suspected for a longer time that black rats can be found in certain residential buildings in towns or even cities.
