What should be done if bitten by a flea? - in detail
If a flea bite occurs, begin by washing the area with mild soap and lukewarm water. Pat the skin dry with a clean towel; avoid rubbing, which can worsen irritation.
Apply an over‑the‑counter antiseptic, such as povidone‑iodine or chlorhexidine, to reduce the risk of bacterial entry. Allow the solution to air‑dry before covering the site, if necessary, with a sterile gauze pad.
For itching or mild inflammation, use a topical antihistamine or hydrocortisone cream (1 %). Apply a thin layer no more than three times daily. Oral antihistamines (e.g., cetirizine 10 mg) are appropriate when itching is widespread or disrupts sleep.
Monitor the bite for signs of infection: increasing redness, swelling, warmth, pus, or fever. If any of these develop, seek medical evaluation promptly. Persistent or severe allergic reactions—such as hives, difficulty breathing, or swelling of the lips or tongue—require immediate emergency care.
Prevent further bites by addressing the source. Wash all bedding, clothing, and pet fabrics in hot water (≥ 60 °C) and dry on high heat. Vacuum carpets, upholstery, and pet areas thoroughly; discard the vacuum bag or clean the canister afterward. Treat pets with a veterinarian‑recommended flea control product (topical, oral, or collar) and repeat treatment according to the product schedule. Consider environmental flea sprays or foggers for heavily infested indoor spaces, following label instructions and ensuring proper ventilation.
Maintain skin integrity by refraining from scratching. If accidental scratching occurs, repeat the cleansing and antiseptic steps to minimize secondary infection.
