Locate observations
Indicate the room or access point involved, when signs appear and where they recur. Distinguish what you saw from what you assume. A factual description is more useful than an uncertain pest name.
Keep a timeline
Note when you first noticed signs, their frequency and recent changes in the home. Travel, a delivery or changed access can provide context without proving the cause.
Prepare useful information
The type of home, affected rooms, visible access points and measures already taken can help you ask the right questions. Keep your contact details handy. Avoid documents and sensitive information unrelated to your situation.
Ask your questions
Ask how identification will be approached, which rooms or access points need examination and what preparation would be necessary. Before agreeing to work, clarify scope, fees, terms and follow-up with the professional you choose.
