The cellar and the apartment are connected spaces
A mouse seen upstairs and signs near cellar storage may or may not have the same route. The building needs an account of both locations. Pipe openings, doors, and accessible voids can connect areas controlled by different residents. An inspection can map those relationships without assuming that every apartment is affected simply because one household reports a concern.
Food and cover can sit outside the reporting unit
A shared storage area or waste container may provide resources that are not visible from the occupied kitchen. Removing animals from one room does not resolve every supporting condition elsewhere. An effective property plan considers control, accessible entry routes, and the food or shelter conditions identified during the assessment. Required building repairs should remain explicit rather than being implied by a general rodent-service label.
One evidence record is better than several incomplete stories
For a Worcester multi-unit home, sightings from separate households should retain their date and room. Fresh activity after work can then be compared with the original distribution. The inspection findings should explain what is known about mice or rats and what remains unconfirmed. Call with the confirmed locations and the building arrangement so the discussion can address the connected spaces, not only the room where the latest animal appeared.
