What should be done about fleas on a person? - in detail
Fleas that have attached to a human require rapid removal, medical assessment, and environmental control.
First, cleanse the skin. Take a thorough shower with hot water and a mild antiseptic soap. While washing, use a fine‑toothed comb to pull any visible insects from hair and body hair. Pat the skin dry with a clean towel; do not rub, which could embed flea mouthparts deeper.
Second, treat the bites. Apply a topical corticosteroid or antihistamine cream to reduce inflammation and itching. If a large number of bites cause systemic symptoms—fever, severe swelling, or signs of infection—seek medical attention promptly. A physician may prescribe oral antihistamines, antibiotics, or a short course of antiparasitic medication such as ivermectin.
Third, eliminate the source.
- Wash all clothing, bedding, and towels in hot water (≥60 °C) and tumble dry on high heat.
- Vacuum carpets, upholstery, and cracks in flooring; discard vacuum bags or clean canisters immediately.
- If pets are present, treat them with a veterinarian‑approved flea control product (topical, oral, or collar).
- Consider applying an environmental insecticide labeled for indoor flea control, following label instructions and ensuring ventilation.
Fourth, prevent re‑infestation. Maintain a routine of weekly pet treatment, regular laundering of personal linens, and periodic vacuuming. Inspect outdoor areas where pets rest; keep grass trimmed and remove debris that can harbor flea larvae.
Finally, monitor the skin for delayed reactions. New bites may appear up to several days after the initial exposure; persistent itching or secondary infection warrants another medical review.
