What should I do if a flea bites me? - in detail
If a flea has pierced the skin, begin by cleansing the area. Wash the bite with mild soap and lukewarm water, then pat dry with a clean towel. This removes surface contaminants and reduces the risk of secondary infection.
Apply a cold compress or an ice pack wrapped in cloth for 5–10 minutes. The cold stimulus constricts blood vessels, which alleviates swelling and numbs the itch temporarily. Repeat every hour as needed during the first few hours.
To control itching, use one of the following topical agents:
- Over‑the‑counter hydrocortisone cream (1 %) applied thinly, up to three times daily.
- Calamine lotion or a menthol‑based gel, applied after each wash.
- Antihistamine cream containing diphenhydramine, applied no more than twice a day.
If oral relief is preferred, an antihistamine tablet such as cetirizine 10 mg or loratadine 10 mg may be taken once daily, provided there are no contraindications. Follow the package instructions or a physician’s dosage recommendation.
Monitor the bite for signs of infection: increasing redness, warmth, pus, or escalating pain. Should any of these develop, seek medical attention promptly. Persistent swelling, a rash spreading beyond the bite site, or fever also warrant professional evaluation.
Prevent future incidents by treating the environment. Wash all bedding, clothing, and pet fabrics in hot water (≥ 130 °F) and dry on high heat. Vacuum carpets and upholstery thoroughly, then discard the vacuum bag. For pets, apply a veterinarian‑approved flea control product—topical spot‑on treatment, oral medication, or a flea‑comb—according to the label schedule.
Maintain regular cleaning routines and inspect pets and living areas weekly. Early detection and prompt treatment of infestations limit exposure and reduce the likelihood of additional bites.
