What will help with a flea bite? - in detail
Flea bites cause itching, redness, and occasional swelling. Prompt relief requires a combination of topical, oral, and environmental measures.
Apply a cold compress for 10–15 minutes to reduce inflammation and numb the area. Follow with an over‑the‑counter antihistamine cream or a hydrocortisone ointment (1 % strength) to suppress the histamine response. If itching persists, an oral antihistamine such as cetirizine or diphenhydramine can be taken according to package directions.
Keep the skin clean. Wash the affected site with mild soap and lukewarm water, then pat dry. Avoid scratching; repeated trauma can lead to secondary bacterial infection. If signs of infection appear—pus, increased warmth, or expanding redness—consult a healthcare professional for possible antibiotics.
For persistent irritation, a topical numbing agent containing lidocaine provides temporary relief. In cases of severe allergic reaction, seek emergency medical care.
Environmental control prevents further bites. Vacuum carpets, upholstery, and pet bedding daily; discard the vacuum bag or empty the canister immediately. Wash pet bedding in hot water (≥ 60 °C) weekly. Treat pets with a veterinarian‑approved flea preventive, such as a topical spot‑on product, oral medication, or a flea collar. Use a household flea spray or fogger that contains an insect growth regulator (IGR) to interrupt the flea life cycle.
