How can fleas be destroyed on the body? - in detail
Fleas that have infested a person’s skin can be eliminated through a combination of immediate removal, topical agents, and systemic treatment.
First, physically remove visible insects. Use fine‑toothed combs or tweezers to grasp each flea near the head and pull steadily outward. After removal, wash the affected area with hot water (≥ 40 °C) and a mild antiseptic soap to reduce irritation and prevent secondary infection.
Second, apply approved topical insecticides. Products containing permethrin (1 %) or pyrethrin are effective when spread evenly over the skin, avoiding mucous membranes and open wounds. Follow the manufacturer’s instructions regarding contact time—typically 10–15 minutes—before rinsing thoroughly. For individuals with sensitive skin, benzyl benzoate (25 %) or sulfur ointments may be used under medical supervision.
Third, consider systemic therapy for extensive infestations. Oral agents such as ivermectin (200 µg/kg) or albendazole (400 mg) can eradicate fleas that have burrowed into hair follicles or deeper skin layers. Dosage must be prescribed by a healthcare professional; contraindications include pregnancy, severe liver disease, and certain neurological conditions.
Fourth, address the environment to prevent reinfestation. Wash clothing, bedding, and towels at 60 °C, then dry on high heat. Vacuum carpets, upholstery, and pet bedding, discarding the vacuum bag or cleaning the canister immediately. Apply residual insecticide sprays (e.g., bifenthrin) to cracks, baseboards, and pet sleeping areas, observing label safety intervals before re-entering the treated space.
Finally, monitor the individual for signs of allergic reaction, fever, or persistent itching. If symptoms persist beyond 48 hours after treatment, seek medical evaluation to rule out secondary infections or allergic dermatitis. Regular follow‑up ensures complete eradication and reduces the risk of recurrence.
