What should a person bitten by a flea do? - in detail
A flea bite often appears as a small, red, raised spot that itches intensely. Immediate care should focus on cleaning the area to reduce the risk of infection. Wash the bite with mild soap and lukewarm water, then pat dry. Apply a mild antiseptic such as povidone‑iodine or hydrogen peroxide.
Observe the bite for signs of worsening. Redness that spreads, swelling, pus, or a fever may indicate secondary infection or an allergic reaction. Persistent itching beyond a few days warrants further treatment.
Therapeutic measures include:
- Oral antihistamines (e.g., cetirizine, diphenhydramine) to alleviate itching and reduce histamine response.
- Topical corticosteroid creams (e.g., hydrocortisone 1 %) applied two to three times daily for up to a week.
- Calamine lotion or a soothing gel containing aloe vera for additional skin comfort.
- Analgesic ointments containing lidocaine for localized pain relief.
Environmental control prevents additional bites. Steps are:
- Wash all bedding, clothing, and towels in hot water (≥ 60 °C) and dry on high heat.
- Vacuum carpets, upholstery, and floor crevices thoroughly; discard the vacuum bag or clean the canister immediately.
- Treat domestic animals with veterinarian‑approved flea preventatives; groom them regularly.
- Apply an insecticide spray or fogger approved for indoor use, focusing on cracks, baseboards, and pet sleeping areas.
Seek professional medical attention if any of the following occur: severe swelling, difficulty breathing, hives, rapid heartbeat, or if the bite fails to improve after several days of self‑care. A healthcare provider may prescribe stronger corticosteroids, antibiotics, or epinephrine autoinjectors for anaphylactic risk.
