This isn't about how clean your home is
Nothing about the visit is a judgment on the home. It's a routine, professional job, same as any other appointment.
Arrival
Your specialist confirms the plan with you before starting, which areas are being treated and roughly how long it will take. If you've requested discreet arrival, this is when that's confirmed too.
During the visit
Depending on the approach, you may be asked to be away from the treated area for part of the visit. Your specialist works through the plan methodically, focused on the areas identified during the inspection.
Right after
Before leaving. Your specialist explains what to expect over the next few days, whether a follow-up visit is scheduled, and what would be worth a call in the meantime. Nothing about the day should end with unanswered questions.
Common questions
How long does a treatment visit usually take?
It depends on the scope of the plan. Your specialist gives you an estimate ahead of the visit.
Do I need to be home the whole time?
Someone with access to the treated areas generally needs to be present, at least at the start and end.
Can I stay in another part of the house?
Often yes, depending on the approach. Your specialist will confirm for your plan.
What if I have questions during the visit?
Ask your specialist directly. That's a normal part of the visit.
