How to remove body lice? - briefly
Use a pediculicide shampoo or lotion (e.g., permethrin 1% or pyrethrin) applied to the entire body, leave it on for the recommended time, then rinse thoroughly; simultaneously launder all clothing, bedding, and towels in hot water (≥130 °F) and dry on high heat, and repeat the treatment after 7–10 days to kill any newly hatched nymphs.
How to remove body lice? - in detail
Body lice infestations require a coordinated approach that targets the parasites, the contaminated clothing, and the surrounding environment.
First, identify the presence of lice by inspecting the body and clothing for small, crab‑like insects and their dark, speckled eggs (nits) attached to seams. Look for intense itching, especially in the groin, armpits, and waistline.
Second, initiate treatment with an approved pediculicide. Apply a lotion or shampoo containing permethrin (1 %) or pyrethrin according to the product label: spread evenly over the entire body, leave for the recommended duration, then rinse thoroughly. Repeat the application after 7–10 days to eliminate newly hatched insects.
Third, decontaminate all personal items.
- Wash clothing, bedding, and towels in hot water (≥ 130 °F / 54 °C) for at least 30 minutes.
- Dry items on high heat for a minimum of 20 minutes.
- For items that cannot be laundered, seal them in a plastic bag for 72 hours; lice cannot survive without a host for that period.
Fourth, maintain personal hygiene to prevent reinfestation.
- Shower daily with soap and warm water.
- Change underwear and socks each day.
- Trim or shave body hair in affected areas to reduce attachment sites.
Fifth, monitor for residual infestation. Conduct a visual inspection 2–3 days after treatment and repeat the lice count weekly for three weeks. If live insects persist, consult a healthcare professional for alternative medications such as ivermectin or malathion.
Finally, educate all household members about transmission routes—direct skin contact and sharing of clothing or bedding—to minimize spread. Implement the outlined steps consistently to achieve complete eradication.
