What should be done if a flea bites? - in detail
When a flea bite occurs, begin with thorough cleansing. Use lukewarm water and mild soap to remove any residual saliva that may aggravate the skin. Pat the area dry with a clean towel; rubbing can increase irritation.
Apply a topical antihistamine or hydrocortisone cream to reduce itching and swelling. For those who prefer non‑medicated options, a thin layer of calamine lotion or a cool compress can provide temporary relief. Limit scratching; repeated trauma can introduce bacteria and lead to secondary infection.
Observe the bite for signs of infection: increasing redness, warmth, pus, or escalating pain. If any of these develop, seek medical evaluation promptly. In cases of known hypersensitivity to flea saliva, systemic antihistamines or a short course of oral corticosteroids may be prescribed by a clinician.
Maintain a clean environment to prevent further bites. Wash bedding, clothing, and pet accessories in hot water. Vacuum carpets and upholstery regularly; discard the vacuum bag or clean the canister afterward. Treat pets with an appropriate flea control product, following veterinary guidance, to eliminate the source.
If the bite persists beyond a few days despite self‑care, or if a rash spreads, consult a healthcare professional to rule out allergic reactions or other dermatological conditions.
