Put events in order without guessing the source
Start with what prompted concern, then note later observations and any change to their location. Add cleaning, products or professional work in the relevant part of the sequence. A useful timeline records events; it does not prove causation simply because one event occurred before another. Keep uncertainty visible when dates or identification cannot be recalled confidently.
For pest control in Bow, explain the property postcode and the space associated with each sign. If different people contributed observations, distinguish their reports. Avoid turning a forwarded account into a new independent sighting. The team needs enough history to understand the present enquiry, not an elaborate narrative unsupported by evidence.
