What to do with pillows if lice appear? - briefly
Isolate the pillow and either wash it on the hottest setting (≥130 °F) for at least 30 minutes followed by a high‑heat dryer cycle, or, if laundering isn’t feasible, seal it in a plastic bag for two weeks to kill the insects. Afterwards, inspect for any remaining nits and replace or clean the pillowcase as needed.
What to do with pillows if lice appear? - in detail
When lice are detected, pillows must be treated immediately to eliminate all life stages and prevent re‑infestation.
First, isolate the affected pillow. Place it in a sealed plastic bag and transport it to a location where it can be processed without contaminating other items.
Heat is the most reliable method. Wash the pillow according to the manufacturer’s instructions, using the hottest water the fabric tolerates (typically 130 °F/54 °C). Follow with a dryer cycle on high heat for at least 30 minutes; the temperature must reach 130 °F to kill nits and adult insects. If the pillow’s label prohibits machine washing, apply a steam cleaner that delivers temperatures above 130 °F, covering the entire surface for several minutes.
For items that cannot endure heat, use a chemical treatment approved for lice. Apply a lice‑specific spray or powder, ensuring full coverage of seams, folds, and the pillowcase. Allow the product to remain for the recommended contact time, then vacuum the pillow thoroughly with a HEPA‑filter vacuum to remove dead insects and debris.
After treatment, launder all pillowcases and surrounding bedding at the same high temperature. Vacuum the mattress, bed frame, and nearby furniture, paying special attention to crevices where nits may hide.
If the pillow shows signs of irreversible damage, replace it with a new, tightly woven model that discourages lice attachment. Store replacement pillows in sealed bags until the household is confirmed lice‑free.
Finally, conduct a follow‑up inspection 48 hours after treatment. Look for live lice or nits on the pillow surface and on the owner’s hair. Repeat the cleaning cycle if any are found. Maintaining a routine of weekly high‑temperature laundering and regular vacuuming reduces the risk of recurrence.
