What should a family do during a lice infestation? - briefly
Apply an FDA‑approved lice treatment to every family member’s hair, follow with a fine‑tooth nit comb to remove nits, wash all bedding, clothing, and personal items in hot water, vacuum the residence thoroughly, and notify close contacts so they can inspect and treat promptly.
What should a family do during a lice infestation? - in detail
When a household discovers a lice outbreak, the first step is to confirm the presence of live insects. Examine the scalp and hair of all family members, focusing on the nape of the neck and behind the ears. Use a fine-tooth comb on wet hair to separate strands; adult lice and viable nits will be visible.
After confirmation, begin treatment promptly:
- Choose an FDA‑approved pediculicide (e.g., permethrin 1% or pyrethrin‑based lotion). Follow the product’s instructions precisely regarding application time and repeat dosing, typically 7–10 days after the initial treatment.
- Apply the medication to every affected person, even those without visible signs, because lice spread quickly within close contact.
- Rinse hair thoroughly, then use a fine-tooth “nit” comb to remove dead insects and eggs. Perform combing at least twice a day for a week.
- Wash all bedding, towels, and clothing worn in the previous 48 hours in hot water (≥130 °F) and dry on high heat. Items that cannot be laundered should be sealed in a plastic bag for two weeks.
Environmental control complements personal treatment:
- Vacuum carpets, upholstered furniture, and car seats; discard the vacuum bag or clean the canister afterward.
- Soak hair accessories, combs, and brushes in hot water (≥130 °F) for 10 minutes.
- Seal non‑washable items (e.g., hats, stuffed toys) in airtight containers for at least two weeks.
Preventive measures reduce the risk of recurrence:
- Instruct children to avoid sharing hats, hairbrushes, headphones, or other personal items.
- Encourage regular head checks, especially after sleepovers, camps, or other group activities.
- Maintain short hair lengths where feasible; longer hair should be tied back and kept clean.
Monitor the situation for at least three weeks. If live lice persist after two treatment cycles, consult a healthcare professional for alternative prescription options such as ivermectin or benzyl alcohol. Document the dates of each treatment and follow‑up combing to ensure complete eradication.
