How to remove fleas from a human? - briefly

How to remove fleas from a human? - in detail
Fleas that have infested a person require prompt removal to prevent irritation, secondary infection, and further spread. The process consists of three coordinated actions: direct treatment of the skin, systemic medication, and environmental decontamination.
First, cleanse the affected areas with warm water and an antiseptic soap. Use a fine-toothed comb or a disposable flea comb to separate adult insects from hair or clothing. After each pass, dispose of the comb’s contents in a sealed container. Apply a topical insecticide approved for human use—such as permethrin 5 % cream—according to the product label, covering all exposed skin. Allow the medication to remain for the recommended duration before rinsing.
Second, obtain a prescription for an oral antiparasitic agent when topical measures are insufficient. Ivermectin, administered in a single dose of 200 µg/kg, effectively eliminates adult fleas and immature stages. Follow up with a second dose after 24–48 hours if symptoms persist. Monitor for adverse reactions and seek medical advice if severe itching, rash, or fever develop.
Third, eradicate the source environment. Wash all bedding, clothing, and towels in hot water (≥60 °C) and tumble‑dry on high heat for at least 30 minutes. Vacuum carpets, upholstery, and cracks in flooring thoroughly; discard the vacuum bag or empty the canister into a sealed bag. Apply a residual spray containing a synthetic pyrethroid to carpets, pet bedding, and indoor cracks, observing the safety interval before re‑entering the treated spaces.
Prevent recurrence by maintaining personal hygiene, using regular flea‑preventive products on pets, and keeping living areas clean. Regular inspection of pets and immediate treatment of any infestation interrupt the life cycle and protect both humans and animals.
