Inspection comes before method
A useful inspection maps signs, harbourages and movement rather than treating every mark on skin as proof. Ask which rooms were checked and why the proposed method fits the evidence.
Flats, houses in multiple occupation and short lets may require coordination beyond one bedroom. A plan that ignores adjoining sleeping areas can miss the route of activity.
- Confirm the target pest
- Record the rooms inspected
- Ask how follow-up will measure change
Residual and contact approaches
Professional insecticide work uses authorised products according to the label and may combine residual placements with non-chemical actions. Occupants should receive clear preparation, re-entry and cleaning instructions.
Steam can kill exposed life stages when the correct equipment and technique reach the harbourage, but it has no residual effect and can miss insulated or inaccessible hiding places.
Controlled heat
Whole-room heat is an engineered process, not simply making a room feel hot. Sensors, airflow, exposure time and the slowest-heating belongings determine whether target conditions reach every relevant location.
Ask who monitors temperatures, which items need protection and what verification follows the treatment. No method removes the need for post-treatment monitoring.
Sources and further checks
Open the source before acting on information that may change, including council services, prices, tenancy rules and product labels.
