What should be done if there are lice? - briefly
Treat the infestation with a lice‑killing shampoo or lotion, follow the product’s timing instructions, then remove nits using a fine‑toothed comb and repeat the treatment after 7–10 days; simultaneously launder clothing, bedding, and personal items in hot water or seal them for two weeks.
What should be done if there are lice? - in detail
When an infestation is identified, immediate action prevents further spread.
First, confirm the presence of live insects by examining the scalp, hair, and clothing. Use a fine-toothed comb on wet hair; moving the comb from the scalp outward reveals nits attached to hair shafts.
Next, select an appropriate treatment:
- Chemical pediculicides – apply a product containing permethrin (1 %) or pyrethrin with piperonyl butoxide according to the label, leaving it on for the recommended duration before rinsing.
- Prescription options – for resistant cases, a physician may prescribe ivermectin lotion or malathion 0.5 % solution.
- Physical removal – wet‑comb method using a fine comb every 2–3 days for two weeks eliminates both lice and nits without chemicals.
After treatment, follow these cleaning steps:
- Wash all worn clothing, bedding, and towels in hot water (≥ 60 °C) and dry on high heat for at least 30 minutes.
- Seal non‑washable items in a sealed plastic bag for two weeks to starve any surviving insects.
- Vacuum carpets, car seats, and upholstered furniture; discard vacuum bags immediately.
Preventive measures reduce recurrence:
- Advise regular head checks, especially in school settings.
- Encourage avoiding head‑to‑head contact and sharing of hats, combs, or hair accessories.
- Recommend routine use of a nit‑comb once a week for families with a recent case.
Finally, schedule a re‑inspection 7–10 days after the initial treatment. If live lice are still observed, repeat the chosen medication or switch to an alternative method. Persistent infestations may require medical evaluation to rule out resistance or secondary skin conditions.
