How should clothing be treated to eliminate bedbugs? - briefly
Wash garments in water at least 120 °F (49 °C) and dry them on the highest heat setting for 30 minutes or longer; alternatively, seal items in a sealed plastic bag for two weeks if heat treatment is unavailable. Ensure all folds and seams are fully exposed during washing and drying to reach the insects.
How should clothing be treated to eliminate bedbugs? - in detail
Treating garments to eradicate bedbugs requires a combination of temperature control, chemical application, and proper handling to prevent re‑infestation.
First, isolate all clothing suspected of contamination. Place items in sealed plastic bags to avoid spreading insects to other areas.
Second, apply heat treatment. Set the dryer to the highest safe temperature (minimum 130 °F / 54 °C) and run a full cycle for at least 30 minutes. Heat penetrates fabrics, killing all life stages of the pest. For items that cannot be tumble‑dried, use a portable heater or a professional heat‑chamber service, maintaining the same temperature for the same duration.
Third, use cold treatment when heat is unsuitable. Seal garments in airtight bags and freeze them at 0 °F (‑18 °C) or lower for a minimum of four days. Extreme cold also proves lethal to bedbugs and their eggs.
Fourth, consider chemical decontamination. Apply an EPA‑registered insecticide spray formulated for fabrics, following label directions for dosage and safety. Ensure even coverage, especially on seams, cuffs, and pockets where insects hide. After spraying, allow the product to dry completely before handling.
Fifth, after thermal or chemical steps, launder all items in hot water (≥120 °F / 49 °C) with detergent. Rinse thoroughly and dry on high heat again for 30 minutes to guarantee any residual bugs are destroyed.
Finally, store treated clothing in clean, sealed containers or vacuum‑sealed bags until the infestation is confirmed eradicated. Inspect garments regularly for signs of reinfestation and repeat the above procedures if necessary.
