Locate all hiding spots, wash bedding at ≥60 °C, vacuum seams, and seal cracks. Follow with heat treatment (≥50 °C for several hours) or a professional pesticide application to eliminate any remaining insects.
How to eradicate domestic bedbugs? - in detail
Eliminating bedbugs from a residence demands a systematic approach that combines inspection, sanitation, chemical treatment, and preventive measures.
Begin with a thorough inspection. Remove all bedding, curtains, and clothing and examine seams, folds, and tufts for live insects, shed skins, or dark spots. Use a flashlight and a magnifying lens to detect hidden colonies in mattress tags, box‑spring seams, headboard cracks, and behind baseboards. Mark infested zones with tape to track progress.
Sanitation follows inspection. Wash all washable fabrics in water hotter than 60 °C (140 °F) for at least 30 minutes; dry them on the highest heat setting for a minimum of 30 minutes. Items that cannot be laundered should be sealed in airtight plastic bags for two weeks, depriving bugs of food and forcing them to die. Vacuum carpets, upholstery, and floor crevices meticulously; immediately discard the vacuum bag or empty the canister into a sealed container.
Chemical and non‑chemical treatments address the surviving population. Apply a registered insecticide formulated for bedbug control to all identified hiding places, following label directions for concentration, application method, and safety precautions. Consider products containing pyrethroids, neonicotinoids, or desiccant dusts such as diatomaceous earth. For resistant infestations, integrate heat treatment: raise room temperature to 50 °C (122 °F) and maintain for at least four hours, ensuring heat penetrates all furniture and structural voids. Steam generators can target localized areas, delivering temperatures above 100 °C (212 °F) directly onto surfaces.
After treatment, conduct a second inspection after 7–10 days to verify mortality and identify any residual activity. Repeat vacuuming and laundering as needed. Install protective encasements on mattresses and box springs; these zippered covers prevent re‑infestation and simplify future monitoring.
Prevent future outbreaks by reducing clutter, sealing cracks in walls and baseboards, and maintaining regular housekeeping routines. Periodically inspect travel luggage, second‑hand furniture, and rental accommodations before introducing them into the home. Early detection and prompt response remain the most effective defense against a resurgence.
