How to treat fleas on people? - in detail
Flea infestations on humans require prompt removal of insects, relief of skin irritation, and elimination of the source.
First, wash the affected area with soap and warm water. Pat dry and apply a cold compress to reduce swelling. Over‑the‑counter antihistamine tablets or topical hydrocortisone cream can alleviate itching and inflammation.
Second, treat the body with an approved topical insecticide. Permethrin 5 % cream, applied to clean skin and left for the recommended duration, kills remaining fleas. Follow product instructions precisely; avoid contact with eyes and mucous membranes.
Third, consider systemic medication when topical agents are insufficient. Oral ivermectin, prescribed by a physician, is effective against ectoparasites and can be used for severe cases. Dosage depends on body weight and must be confirmed by a healthcare professional.
Fourth, address the environment to prevent re‑infestation.
- Vacuum carpets, upholstery, and bedding thoroughly; discard vacuum bags immediately.
- Wash all clothing, linens, and towels in hot water (≥ 60 °C) and dry on high heat.
- Apply a household flea spray containing an insect growth regulator (e.g., methoprene) to floors, baseboards, and pet sleeping areas.
- Treat pets with veterinarian‑approved flea control products; untreated animals perpetuate the cycle.
Finally, seek medical evaluation if symptoms persist, if a secondary infection develops, or if systemic medication is considered. A clinician can confirm diagnosis, rule out other skin conditions, and prescribe appropriate therapy.
