I was bitten by a flea — what should I do? - in detail
A flea bite typically appears as a small, red, raised spot surrounded by a halo of irritation. It may itch intensely and, in some cases, develop a tiny blister or a cluster of puncture marks.
Immediate actions focus on reducing discomfort and preventing infection.
- Gently wash the area with lukewarm water and mild soap.
- Pat dry with a clean towel; avoid rubbing.
Applying an antiseptic limits bacterial invasion. Suitable options include hydrogen peroxide, povidone‑iodine solution, or an alcohol‑based wipe. Allow the product to air‑dry before covering the bite.
To alleviate itching, consider the following pharmacological measures.
- Oral antihistamines such as cetirizine or diphenhydramine reduce histamine response.
- Topical corticosteroid creams (e.g., 1 % hydrocortisone) diminish local inflammation.
- Calamine lotion or a paste of baking soda and water provides a soothing barrier.
Observe the bite for signs of complication. Seek medical evaluation if any of the following occur:
- Rapid expansion of redness or warmth spreading beyond the bite.
- Presence of pus, foul odor, or persistent swelling.
- Fever, chills, or generalized rash.
Prevention reduces future incidents. Maintain regular cleaning of bedding, carpets, and pet habitats. Use approved flea control products on animals and treat indoor environments with appropriate insecticides. Vacuuming frequently removes eggs and larvae, lowering infestation risk.
