How can lice be killed on pillows? - briefly
Wash pillowcases and any removable covers in water at 130 °F (54 °C) or hotter and tumble‑dry on high heat for at least 30 minutes; alternatively, seal the pillow in a zip‑top bag for two weeks to deprive lice of food and moisture. If the pillow itself cannot be laundered, apply an EPA‑registered lice spray per label instructions and then store it in a sealed bag for the same two‑week period.
How can lice be killed on pillows? - in detail
Eliminating head‑lice infestations from bedding requires a combination of physical and chemical methods that destroy both adult insects and their eggs.
First, separate the pillow from other laundry and check the care label. If the cover is removable, launder it in hot water (minimum 130 °F/54 °C) for at least 30 minutes. Use a high‑temperature dryer cycle for the same duration; heat at this level kills lice and nits.
If the pillow itself cannot be washed, apply one of the following heat‑based approaches:
- Place the pillow in a dryer on the highest setting for 20–30 minutes, ensuring the material tolerates high heat.
- Use a portable garment steamer, directing steam across the surface for several minutes to raise the temperature above 120 °F (49 °C).
For items that cannot withstand heat, employ freezing: seal the pillow in a plastic bag and store it in a freezer set to 0 °F (‑18 °C) for at least 48 hours. The sustained low temperature kills all life stages.
Chemical treatment is an alternative when heat or cold is unsuitable. Apply a lice‑specific spray containing 0.5 % permethrin or 1 % pyrethrin, following the manufacturer’s instructions for exposure time and ventilation. After spraying, allow the pillow to dry completely before reuse.
Mechanical removal can supplement other methods. Vacuum the pillow with a HEPA‑rated attachment, moving the nozzle slowly over all surfaces for at least one minute per side. Dispose of the vacuum bag or clean the canister immediately to prevent re‑infestation.
Finally, protect the pillow with an encasement designed to block insects. Choose a zippered cover rated for lice control, and wash it regularly in hot water. Maintaining a clean environment—regular laundering of bedding, frequent vacuuming, and minimizing contact with infested hair—prevents recurrence.
