The premisesAvoid making a small uncertainty a large assumption
Noise, damage and insect sightings can have different explanations. At an SW20 property, the useful question is what supports the suspected cause. We ask about the sequence of events and any recent work or movement of items, then use that account to guide checks rather than extending the concern to every room.
What you have noticedCapture the detail that a phone call can miss
A close photograph of an insect, a wider view of its location and the date can be more informative together than a description such as tiny bugs. For rodent concerns, explain the position of damage or droppings. Never handle an unknown pest or put yourself at risk to improve a photograph.
