How should pillows and mattresses be treated for lice? - briefly
Wash pillows and any removable covers in water at least 130 °F (54 °C) and dry on the highest heat setting; vacuum the mattress surface, then seal it in a lice‑proof encasement and run a hot‑steam or approved insecticide treatment if infestation persists. Repeat the process after seven days to eliminate any newly hatched lice.
How should pillows and mattresses be treated for lice? - in detail
Lice infestations require thorough decontamination of all sleeping surfaces. Bedding items must be subjected to high‑temperature processes that destroy both adult insects and eggs. Wash all pillowcases, duvet covers, and removable pillow covers in water at 130 °F (54 °C) or hotter for at least 10 minutes. If the fabric cannot tolerate such heat, place it in a sealed plastic bag and store it in a freezer set to –4 °F (–20 °C) for a minimum of 48 hours; this temperature kills lice and nits.
Non‑removable pillows and mattresses cannot be laundered, so apply heat directly. Use a steam cleaner that reaches at least 212 °F (100 °C); pass the steam nozzle slowly over the entire surface, allowing the moisture to penetrate seams and folds. Follow with a high‑heat dryer cycle for any removable covers, using the hottest setting the material can safely endure.
Vacuuming eliminates loose insects and eggs from crevices. Employ a vacuum equipped with a HEPA filter, moving slowly across the mattress, pillow tops, and surrounding bed frame. After vacuuming, discard the bag or clean the canister according to manufacturer instructions to prevent re‑infestation.
Chemical options are reserved for resistant cases. Apply an FDA‑approved lice treatment spray specifically labeled for fabrics, following the product’s contact time and safety guidelines. Avoid over‑application, and ensure the area is well‑ventilated during and after treatment.
Finally, isolate the treated bedding for at least 24 hours before reuse. Store cleaned items in sealed plastic bags or airtight containers to prevent re‑contamination. Repeat the washing or steaming cycle after one week to eradicate any eggs that may have survived the initial treatment.
