A pest sighting reported by the cleaner on St Marys premises

Droppings behind a fridge or under a bench. Gnaw marks on packaging in a store room. Activity around an external bin area at night. A gap under a door that has been widened. Grease and food residue accumulating where nobody looks. Most of those are found while moving something to clean behind it, which is not an activity anyone else in the building performs regularly. Nobody else in the building performs that activity on any kind of cycle.

The timing helps too. Rodent and insect activity is far more visible in a quiet building at night than during a working day, so a cleaner working an evening attendance sees things that a daytime inspection will not. That combination of access and timing makes the crew a genuinely useful early warning system, provided there is somewhere for the report to go. Access and timing together make the crew a useful early warning system.

A sighting tells a pest controller there is a problem. The conditions tell them why. A bin store door that does not close, food waste in a general bin over a weekend, a gap at a roller door, stored goods against a wall with no inspection gap, standing water in a plant room. Those are the things that sustain activity, and they are frequently within somebody's power to fix immediately. Many of them are fixable immediately by somebody who simply did not know.

Reporting them also identifies where cleaning practice is part of the problem. A bin store that is not being washed down, waste bags left beside a full bin, or food debris in a breakout area not being addressed are all cleaning matters, and the honest response is to fix them rather than to report a rodent problem that the cleaning arrangement is helping to sustain. Reporting a problem the cleaning is helping to sustain would not be an honest response.

Cleaners do not lay baits, move bait stations, set traps or apply pest products. Beyond the licensing question, an uncoordinated response actively interferes with a proper programme: a moved bait station produces misleading monitoring data, and an ad hoc trap catches something the controller was tracking. The instruction is to report and to avoid disturbing existing stations. Disturbing a monitor is worse than doing nothing, which is why the rule is absolute.

Coordination with the pest controller is worth arranging where activity is ongoing. A controller who knows what the cleaning crew is seeing, and when, gets information nobody else can give them. Equally, a crew told which areas are under treatment and what not to disturb avoids undoing the programme while cleaning around it. A short exchange between the crew and the controller is usually all the coordination needed, and it costs neither party anything.
