Inside activity deserves a closer description
Seeing an insect after switching on a light can be unsettling. Note whether the sighting was beneath the refrigerator, beside the sink, or on an outside step. If you can safely photograph it without moving appliances or reaching into a gap, include the surrounding surface for scale. One sighting does not reveal the species or establish how much activity is hidden from view.
Look at the conditions around the hiding place
Food residue, water, clutter, and narrow sheltered spaces can all be relevant to an inspection. Explain any leaks you know about and where dry food or pet bowls are kept. This is useful context, not a judgment about housekeeping. In a rental or adjoining property, describe shared plumbing and access arrangements so the discussion covers more than the visible insect in one room.
Keep treatment history part of the picture
Tell the person assessing the problem about sprays, foggers, baits, or other products already used. Do not add products simply because another roach appears; ask how that might affect the proposed approach. Discuss what needs to be moved, how food and utensils should be protected, and what evidence will be used to judge progress after the first visit.
