What to do if fleas bite? - in detail
Flea bites produce small, red, itchy punctures that often appear in clusters on the lower legs, ankles, and feet. Immediate care reduces irritation and lowers the risk of secondary infection.
First, cleanse the area with mild soap and lukewarm water. Gently pat dry with a clean towel; avoid rubbing, which can worsen inflammation. Apply a cold compress for 10–15 minutes to diminish swelling and numb itching.
Next, use topical treatments:
- Over‑the‑counter hydrocortisone cream (1 %) applied twice daily for up to 7 days.
- Calamine lotion or a zinc‑oxide paste to soothe skin and dry excess moisture.
- Antihistamine cream containing diphenhydramine for rapid itch relief.
If oral medication is preferred, a non‑prescription antihistamine such as cetirizine or diphenhydramine can be taken according to package instructions. For severe itching, a short course of oral corticosteroids may be prescribed by a healthcare professional.
Prevent further bites by addressing the source:
- Wash all bedding, clothing, and pet accessories in hot water (≥ 60 °C) and dry on high heat.
- Vacuum carpets, rugs, and upholstery thoroughly; discard the vacuum bag or clean the canister immediately.
- Treat domestic animals with veterinarian‑approved flea control products, following label directions.
- Apply a residual insecticide to indoor cracks, baseboards, and pet sleeping areas, ensuring ventilation and adherence to safety guidelines.
Monitor the lesions for signs of infection: increasing redness, warmth, pus, or fever. Seek medical attention promptly if any of these symptoms develop, or if the individual has known allergies to insect bites, asthma, or a compromised immune system.
After the acute phase, maintain skin integrity by keeping the area moisturized with a fragrance‑free emollient and avoiding scratching. Persistent hyperpigmentation may fade over weeks; if discoloration remains, a dermatologist can recommend topical agents such as hydroquinone or retinoids.
