How to prepare for professional bed bug treatment

A professional bed bug treatment is only as good as the preparation that goes with it. Skimping on prep is the single most common reason a treatment doesn’t fully work — bed bugs survive in an untreated pile of clothing or a cluttered corner and re-infest the room. Your contractor will give you a specific prep sheet, but here’s what to expect and a general checklist to get ready.

Before the visit — for any treatment

• Launder on heat: wash and tumble-dry all bedding, curtains and clothing from the affected rooms on the hottest setting the fabric allows, then seal it in bags until after treatment
• Declutter: the fewer hiding places, the more effective the treatment — bag up loose items (but don’t move bags into clean rooms)
• Don’t move furniture or belongings into other rooms — you’ll just spread the problem
• Pull furniture slightly away from walls if asked, so the technician can reach skirting and voids
• Make sure the contractor can access the whole affected area, including under beds and inside wardrobes

Extra prep for heat treatment

Heat treatment raises the whole room to 55–60°C, so anything that could melt, warp or be damaged by heat needs to come out first. Your contractor will give you a list, but it typically includes:

• Aerosols, lighters and pressurised cans (a safety must — never leave these in a heated room)
• Candles, crayons, chocolate and other meltables
• Heat-sensitive electronics, musical instruments and vinyl records (check with your contractor)
• Houseplants and, of course, pets — including fish tanks
• Any medication that must be kept cool

Extra prep for chemical treatment

For insecticide treatment, prep is usually lighter but you’ll need to keep pets and people out of treated rooms until surfaces are dry (your contractor will say how long), and avoid washing or wiping treated skirting and edges afterwards — the residual product is what keeps killing bugs over the following weeks.

During and after

You’ll usually need to be out of the property for the treatment (several hours for heat, a shorter window for chemical). Afterwards, resist the urge to deep-clean straight away — vacuuming and scrubbing can remove residual product or disturb monitoring. Follow your contractor’s aftercare advice, keep laundered items sealed until they confirm it’s safe, and report any further activity promptly so a follow-up can be arranged if needed.
