Procure a documented programme
Ask providers to define inspection boundaries, response times, out-of-hours limits, room release criteria, reporting format and escalation when adjoining rooms show evidence.
Check commercial insurance and competence for the methods proposed.
Verify before reopening
A room-release decision should use the treatment method, inspection result and agreed monitoring window. Keep the record with the room history.
Use trend data to improve luggage, linen and housekeeping procedures without publishing unsupported eradication claims.
Sources and further checks
Open the source before acting on information that may change, including council services, prices, tenancy rules and product labels.
