Apply a pediculicide shampoo or lotion as directed, comb out all nits with a fine-tooth comb, and repeat the treatment after 7–10 days; then wash bedding, clothing, and personal items in hot water and vacuum the living area. Check all household members and treat any additional cases promptly.
What should you do if you have lice at home? - in detail
If you find lice in your household, act promptly to eliminate the infestation and prevent spread.
First, confirm the presence of live insects or nits on the scalp or hair shafts. Use a fine-tooth comb on wet, conditioned hair to locate eggs attached within ¼ inch of the scalp. Separate any infested sections for treatment.
Next, select an appropriate product. Over‑the‑counter pediculicides containing 1 % permethrin or 0.5 % pyrethrin are effective for most cases. Follow the label precisely: apply to dry hair, leave for the recommended duration (usually 10 minutes), then rinse thoroughly. For resistant populations, a 0.5 % malathion lotion or a prescription ivermectin preparation may be required; consult a healthcare professional before use.
After the initial application, repeat treatment after 7–9 days to kill newly hatched nymphs that survived the first dose. During the interval, wash all personal items that came into contact with the head: pillowcases, bedding, towels, hats, scarves, and hairbrushes. Use hot water (≥130 °F/54 °C) and high‑heat dryer cycles; items that cannot be laundered should be sealed in plastic bags for two weeks.
Thoroughly clean the environment. Vacuum carpets, upholstery, and vehicle seats. Dispose of vacuum bags or empty containers promptly. Do not spray insecticides in the living space; they are unnecessary and may pose health risks.
Maintain ongoing monitoring. Examine each family member’s hair daily for at least three weeks. If any individual continues to show signs of infestation after two treatment cycles, seek medical advice for alternative therapies.
Finally, educate household members about prevention: avoid sharing combs, hats, or hair accessories; discourage head‑to‑head contact during play; and conduct regular scalp inspections, especially in school‑age children.
By adhering to these steps, you can eradicate the parasites, minimize re‑infestation, and protect the health of everyone in the home.
