What should be done if there are lice and nits? - briefly
Apply a proven pediculicide to the hair and scalp according to the label directions, then comb out all nits with a fine‑toothed nit comb after each treatment. Wash bedding, clothing, and personal items in hot water and vacuum the living area to prevent re‑infestation.
What should be done if there are lice and nits? - in detail
When live insects or their eggs are found on a person’s scalp, immediate action is required to stop spreading and to eliminate the problem.
First, isolate the affected individual from close contact with others until treatment is complete. Wash all clothing, bedding, and personal items in hot water (minimum 130 °F/54 °C) and dry on high heat. Items that cannot be laundered should be sealed in a plastic bag for two weeks to deprive lice of a host.
Next, apply an approved topical pediculicide according to the product’s instructions. Common active ingredients include permethrin 1 % or pyrethrin‑based formulas. Apply the solution to dry hair, leave it for the specified time, then rinse thoroughly. For resistant cases, a second‑generation agent such as ivermectin or malathion may be prescribed by a healthcare professional.
After the initial treatment, comb the hair with a fine‑toothed nit comb. Perform the following routine:
- Section hair into 1‑inch sections.
- Run the comb from scalp to tip, wiping each pass on a damp cloth.
- Repeat every 2–3 days for ten days, ensuring all nits are removed.
If any live insects remain after the first application, repeat the pediculicide after seven days, as newly hatched lice may have emerged. Continue nit‑combing throughout the repeat cycle.
Finally, educate all close contacts about detection and preventive measures: avoid head‑to‑head contact, do not share hats, combs, or pillows, and perform regular scalp inspections.
Following this protocol eliminates the infestation, prevents reinfestation, and minimizes disruption to daily activities.
