How to eliminate lice from bedding? - briefly
Clean all bedding by laundering sheets, pillowcases, and blankets in water of at least 130 °F (54 °C) and drying on a high‑heat setting for at least 30 minutes. Afterwards, vacuum the mattress, bed frame, and surrounding floor, discarding the vacuum contents in a sealed bag.
How to eliminate lice from bedding? - in detail
Removing lice and their eggs from bed linens requires a systematic approach that combines heat, chemical treatment, and thorough environmental cleaning.
First, separate all bedding, pillowcases, blankets, and mattress protectors. Wash each item in hot water at a minimum temperature of 130 °F (54 °C) for at least 10 minutes. The heat destroys both adult insects and nymphs. If the fabric label permits, increase the temperature to 140 °F (60 °C) for added assurance. After washing, place the items in a dryer on the highest heat setting for a minimum of 30 minutes; the sustained heat eliminates any surviving stages.
Second, treat items that cannot be laundered at high temperatures. Seal these pieces in a heavy-duty plastic bag for two weeks, a period that exceeds the lice life cycle, preventing hatching. Alternatively, apply a laundry‑safe insecticide spray labeled for use on fabrics, following the manufacturer’s dosage instructions and allowing the recommended drying time before reuse.
Third, address the mattress and surrounding surfaces. Vacuum the entire mattress, box spring, and bed frame with a HEPA‑rated vacuum, paying special attention to seams, folds, and crevices where eggs may be lodged. Immediately empty the vacuum bag or container into a sealed trash bag and discard it outdoors. After vacuuming, apply a steam cleaner set to at least 212 °F (100 °C); the steam penetrates fabric layers and kills any remaining organisms. Allow the mattress to dry completely before re‑covering.
Fourth, use a protective encasement for the mattress and pillow. Choose a zippered cover that is certified lice‑proof, ensuring it fully encloses the item. Maintain the encasement for at least one month, checking regularly for signs of infestation.
Fifth, implement preventive measures to reduce re‑infestation risk:
- Keep hair tied back and away from the pillow while sleeping.
- Wash personal bedding weekly in hot water.
- Store unused linens in sealed plastic containers.
- Avoid sharing blankets, pillows, or headgear.
- Perform routine vacuuming of the bedroom, focusing on upholstered furniture and carpet edges.
Finally, monitor for recurrence. Inspect the scalp and hair weekly for live insects or nits, and repeat the cleaning protocol promptly if any are detected. Consistent application of these steps eradicates lice from sleeping areas and prevents future outbreaks.
