Keep your observation separate from another person’s report
A neighbour’s concern may be useful context, but it does not prove your rooms have the same problem. Explain what you observed directly and what came from someone else. Keep dates and locations where available. If several people repeat one original sighting, say so rather than describing the repetitions as independent findings.
For Bethnal Green pest enquiries, this distinction helps organise assessment in premises with shared or adjoining spaces. It does not imply that local buildings have a particular infestation pattern. Tell the team which areas you control and which belong to another occupier or manager. Access and permission must be agreed before those spaces are treated as available.
