What to do if a flea bites a person? - in detail

A flea bite appears as a tiny, red, raised spot, often with a central puncture. The skin may itch, swell, or develop a halo of redness. Prompt care reduces discomfort and prevents infection.

1. Immediate cleaning – Wash the area with mild soap and lukewarm water. Pat dry with a clean towel; avoid rubbing, which can irritate the skin further.

2. Symptom relief

   • Apply a cold compress for 5–10 minutes to lessen swelling.
   • Use an over‑the‑counter antihistamine (e.g., cetirizine, diphenhydramine) according to package directions to control itching.
   • Apply a 1 % hydrocortisone cream or calamine lotion to the bite; repeat every 4–6 hours if needed.

3. Prevent secondary infection – Do not scratch. If the bite breaks the skin, clean again and cover with a sterile adhesive bandage. Watch for pus, increasing redness, or warmth, which signal bacterial involvement.

4. When to seek professional care – Seek medical attention if any of the following occur: extensive swelling, hives, breathing difficulty, fever, or signs of infection such as pus or rapidly spreading redness.

5. Environmental control – Eliminate the source to avoid further bites.

   • Treat pets with veterinary‑approved flea preventives (topical, oral, or collar formulations).
   • Wash all bedding, clothing, and pet blankets in water ≥ 60 °C; dry on high heat.
   • Vacuum carpets, rugs, and upholstery thoroughly; discard the vacuum bag or clean the canister immediately.
   • Apply a flea‑specific insecticide spray or fogger to floors, baseboards, and pet sleeping areas, following label instructions.
   • Consider professional pest‑control services for severe infestations.

6. Long‑term prevention – Maintain regular flea treatment for animals, inspect pets weekly for live insects, and keep indoor environments clean and dry. Use flea‑preventive collars or spot‑on products year‑round in regions where fleas are endemic.

Following these steps controls the immediate reaction, reduces the risk of complications, and addresses the underlying infestation that caused the bite.
