## Before the visit

A provider needs enough information to decide whether an inspection, treatment or monitoring visit is appropriate. Be ready to describe the physical evidence, rooms involved, previous DIY or professional work, vulnerable occupants and any access limitations.

A telephone description can organise the appointment, but it should not be used to manufacture certainty. Ask whether the price assumes confirmed bed bugs and what happens if the inspection does not support that diagnosis.

## During the inspection

The technician should concentrate on likely harbourages and the places people rest. A useful inspection explains the finding rather than simply announcing it. Where practical, ask to see the evidence or photographs and understand why connected rooms are included or excluded.

## The written plan

The plan should identify the property or rooms, preparation tasks, treatment method, products where applicable, safety requirements, visit schedule, price and follow-up. If a heat service is proposed, it should explain temperature monitoring and sensitive-item handling. If an insecticidal service is proposed, authorised use and re-entry instructions should be clear.

The HSE's [biocide guidance](https://www.hse.gov.uk/biocides/using/overview.htm) emphasises correct use, storage and disposal. A professional should not tell occupants to improvise with unlabelled decanted products.

## What follow-up means

Follow-up may include a repeat inspection, monitoring results, further targeted work or confirmation that no fresh evidence has appeared. Ask for the timing and the evidence threshold used. “Guaranteed” is not useful unless the duration, included visits and exclusions are written down.

## Red flags in a sales conversation

Be cautious when a seller guarantees eradication without asking about the property, insists that every item must be discarded, refuses to name the treatment method, pressures for immediate payment or uses an accreditation that cannot be verified. A clear provider should be willing to explain what is and is not included.

GOV.UK notes that householders can ask the local council about pest-control services or hire a pest controller. Compare the service scope alongside the price.
