Inspection priorities
- Rat and mouse displacement following site clearance
- Cockroaches exposed during demolition of older buildings
- Wasps nesting in site cabins and stored materials
- Ants nesting in ground disturbance around foundations
Build a practical service specification
Map delivery points, food storage, waste areas, staff facilities and shared routes. Agree when monitoring can take place without disrupting operations and identify the person responsible for following up recommendations.
What to ask your contractor to provide
- A dated inspection report with findings and evidence.
- A site plan showing monitoring points where relevant.
- Treatment and safety instructions appropriate to the premises.
- Clear escalation contacts and an agreed response process.
- Written prevention recommendations, owners and review dates.
These apply to any commercial premises. For the legal duty that sits behind them, what an environmental health officer looks for on an unannounced visit, and how to specify scope, reporting and response before you compare prices, read the commercial pest control guide.
