What to do if a flea bites you? - in detail
If a flea pierces the skin, the immediate goal is to reduce irritation, prevent infection, and stop further bites.
First, cleanse the area with mild soap and lukewarm water. Rinse thoroughly, then pat dry with a clean towel. This removes saliva and potential pathogens introduced by the insect.
Apply a cold compress or an ice pack wrapped in a cloth for 5–10 minutes. The cold reduces swelling and numbs the itch temporarily. Repeat as needed, allowing the skin to warm between applications.
Topical treatments may include:
- Over‑the‑counter hydrocortisone cream (1 %) applied thinly to the bite, no more than three times daily.
- Antihistamine ointment containing diphenhydramine for additional itch relief.
- Calamine lotion or a zinc‑oxide paste to dry out the lesion.
If oral antihistamines are preferred, a standard dose of cetirizine or loratadine can be taken according to package instructions, especially when multiple bites cause widespread discomfort.
Monitor the bite for signs of infection: increasing redness, warmth, pus, or escalating pain. Should any of these appear, seek medical attention promptly. A healthcare provider may prescribe topical antibiotics or a short course of oral antibiotics if bacterial involvement is suspected.
To avoid recurrence, address the source. Treat pets with veterinarian‑approved flea control products, wash bedding in hot water, vacuum carpets and upholstery, and consider an environmental flea spray or fogger if infestation is extensive. Regular grooming and inspection of animals help detect early infestations before they spread to humans.
Finally, keep nails trimmed to minimize skin damage from scratching, which can introduce bacteria and worsen the lesion. Use protective gloves when handling pets or cleaning areas known to harbor fleas until the problem is resolved.
