Does Heat Kill Lice on Humans?
Heat can be an effective method for eliminating lice infestations on humans. Various heat-based treatments can kill lice and their eggs (nits) by damaging their proteins and causing dehydration.
Here are some common heat treatments for lice:
| Method | Effectiveness | Considerations |
|---|---|---|
| Hot water treatment | Highly effective | – Wash hair and clothing in hot water (at least 55°C) for 5 minutes. – Dry on high heat. |
| Blow drying | Effective for nymphs and adults | – Use a blow dryer on high heat for 30 minutes, focusing on the scalp and hair shafts. – Comb hair to remove dead lice and nits. |
