A quick glimpse needs a cautious description
If an insect disappears beneath a cabinet, say that rather than assuming where it nests. A safe photograph may help with identification on a later sighting. Record the time, the room, and whether it was near stored food or water. Insects can resemble one another, and a single sighting cannot establish a cockroach species or reveal how many may be concealed elsewhere in the building.
Recent items and existing conditions both count
Mention newly brought-in packaging if it is relevant, but do not assume it explains the source. Leaks, gaps around pipes, food residue, and narrow sheltered spaces are also useful inspection context. In a multi-unit property, describe shared walls and access limitations. The conversation should cover the evidence at your home without blaming a delivery, a neighbor, or housekeeping based on one uncertain observation.
Keep the preparation tied to the work
Ask what should happen to food, utensils, cabinet contents, and pet supplies before a visit. Explain any products already applied so a new plan does not ignore treatment history. Confirm whether monitoring is included and how follow-up decisions are made. Avoid moving suspect boxes into another room or adding a fogger while waiting for instructions specific to the identified pest and proposed approach.
