Separate what is new from what is newly found
Opening a basement cabinet for the first time in months may reveal signs with an uncertain age. Say that during the call. If packaging you checked yesterday is damaged today, record that separately. A photograph and a simple date can help describe the pattern without handling suspected droppings or taking apart stored belongings to look for more evidence in a hidden corner.
Describe the connection to the house
An attached garage, cellar stair, or pipe opening may be relevant even when the first signs are away from the kitchen. Mention birdseed, pet food, or other stored supplies, and explain where doors are used frequently. Do not climb into a tight void or move heavy appliances to investigate. The assessment should account for access and the people and animals using the building.
Ask how the plan will be checked
Discuss what evidence will be monitored, how devices would be positioned securely, and which entry repairs are recommended. Confirm whether those repairs and any cleanup are included in the proposed price. Suspected rodent waste needs appropriate handling, not dry sweeping or ordinary vacuuming. Ask for current cleanup instructions and keep household members away from contaminated storage until you understand the next step.
