Keep a short record
Note where you noticed the problem, when it began and whether it has appeared elsewhere. A repeated location is useful even if you cannot identify the pest. An existing photo or a description of droppings, marks, noises or damage can give the inspector a starting point.
Discuss access before the visit
Tell the service contact about shared rooms, roof access, locked gates or building entry procedures. In an apartment, a superintendent may need to authorize access beyond the unit. Mention pets and any rooms that cannot be entered so the plan can account for them.
Wait for preparation instructions
Different pests and methods require different preparation. Do not assume you need to empty every cupboard, discard furniture or move belongings to another room. Ask for instructions specific to the proposed visit, especially where food, textiles or sleeping areas are involved.
Ask how progress will be checked
A good conversation covers the evidence, options, likely follow-up and any work the property owner needs to arrange. Keep the written scope and aftercare instructions. Report changes through the agreed contact so a return visit can respond to what is actually happening.
