What should be done when bedbugs are present? - in detail
When an infestation is discovered, immediate containment is essential. Isolate the affected sleeping area by removing bedding, clothing, and personal items and sealing them in plastic bags. Wash all washable fabrics in hot water (minimum 120 °F/49 °C) and dry on the highest heat setting for at least 30 minutes; non‑washable items should be placed in a freezer at –20 °C (–4 °F) for 72 hours.
Inspect surrounding furniture, cracks, and baseboards for live insects, eggs, and shed skins. Use a flashlight and a fine‑toothed comb to dislodge hidden bugs. Vacuum thoroughly, paying special attention to seams, folds, and mattress tufts; discard the vacuum bag or empty the canister into a sealed bag outside the home.
Apply a residual insecticide labeled for bed‑bug control to cracks, crevices, and the perimeter of the room. Follow label directions for dosage, safety precautions, and re‑application intervals. For items that cannot be treated with chemicals, consider heat‑based methods: steam cleaners set to at least 130 °F (54 °C) can penetrate fabrics and kill all life stages on contact.
Engage a licensed pest‑management professional for comprehensive eradication. Professionals can perform whole‑room heat treatment (heating the space to 135 °F/57 °C for 4–6 hours) or targeted fumigation, both of which provide higher success rates than DIY measures alone.
After treatment, monitor the area using interceptor devices placed under bed legs and sticky traps near suspected harborages. Replace mattress encasements with certified bed‑bug‑proof covers and keep clutter to a minimum to reduce hiding places. Conduct periodic inspections, especially after travel or acquiring second‑hand furniture, to detect re‑infestation early.
