How should I treat bed linens for bed bugs? - briefly
Wash the linens in water that reaches at least 120 °F (49 °C) and maintain that temperature for a minimum of 30 minutes, then tumble‑dry on the highest heat setting for another 30 minutes to eliminate all life stages of the pest. Store the cleaned items in airtight plastic containers until the infestation is confirmed cleared.
How should I treat bed linens for bed bugs? - in detail
Proper handling of contaminated bedding requires a systematic approach to eliminate all life stages of the pest and prevent re‑infestation.
First, isolate the items. Place sheets, pillowcases, blankets, and removable mattress covers in sealed plastic bags to contain any escaping insects during transport to the washing area.
Second, apply heat. Machine‑wash the fabrics on the hottest setting the material tolerates, typically 60 °C (140 °F) or higher, for at least 30 minutes. Follow immediately with a high‑heat dryer cycle lasting a minimum of 30 minutes; temperatures above 55 °C (130 °F) are lethal to eggs, nymphs, and adults.
Third, consider alternative thermal methods when laundering is impossible. Steam cleaners set to a minimum of 100 °C (212 °F) can treat curtains, duvet covers, and delicate items. For small accessories, a portable heat chamber reaching 70 °C (158 °F) for 15 minutes provides effective sterilization.
Fourth, use freezing for heat‑sensitive textiles. Seal the items in airtight bags and place them in a freezer maintaining –18 °C (0 °F) or lower for at least four days. This temperature kills all developmental stages.
Fifth, inspect and repeat. After each treatment, examine seams, folds, and stitching under a bright light or magnifying glass. Any surviving insects necessitate a repeat of the chosen method.
Sixth, protect cleaned linens. Store them in vacuum‑sealed bags or containers with tight‑closing lids. Add a desiccant packet to reduce humidity, which discourages future infestations.
Seventh, implement preventive measures.
- Encase mattresses and box springs in certified encasements that zip securely.
- Reduce clutter around the sleeping area to limit hiding places.
- Vacuum the bedroom regularly, discarding the vacuum bag or cleaning the canister outside the home.
- Wash all bedding weekly during an active infestation, maintaining the high‑temperature protocol.
By following these steps—isolating, applying heat or cold, inspecting, and securing—bed linens become free of the pest, and the risk of resurgence is minimized.
