The premisesLook beyond the spot where it appeared
A mouse seen beside a cooker may have arrived through a different part of the room; an insect by a window may have developed elsewhere. At an SE2 address, we ask about adjoining spaces and recent changes without assuming they are affected. That conversation helps us decide where inspection should begin.
What you have noticedKeep different observations separate
Write down whether you found droppings, damaged packaging, crawling insects or repeated flight activity. These clues do not necessarily describe the same problem. A photograph taken before cleaning can help, provided you can take it safely. Please do not reach into cavities or disturb a suspected nest to obtain a closer view.
