What to do if fleas have bitten a person? - in detail
When a flea bite appears on the skin, immediate care focuses on relieving irritation, preventing infection, and eliminating the source of the insects.
First, cleanse the affected area with mild soap and lukewarm water. Pat the skin dry with a clean towel; avoid rubbing, which can worsen inflammation.
Apply a topical anti‑itch agent such as hydrocortisone cream (1 %) or a calamine lotion. For individuals with sensitive skin, a thin layer of aloe‑gel may provide soothing relief. If swelling is pronounced, a cold compress for 10–15 minutes can reduce edema.
Monitor the reaction for signs of secondary infection: increasing redness, warmth, pus, or fever. Should any of these symptoms develop, seek medical attention promptly. A healthcare provider may prescribe oral antibiotics or stronger corticosteroids.
To stop further bites, address the flea infestation in the environment:
- Vacuum carpets, rugs, and upholstery thoroughly; discard the vacuum bag or clean the canister afterward.
- Wash all bedding, clothing, and pet blankets in hot water (minimum 60 °C) and dry on high heat.
- Treat pets with a veterinarian‑approved flea control product; repeat according to the label schedule.
- Apply an insecticide spray or powder labeled for indoor flea control to cracks, baseboards, and pet sleeping areas; follow safety instructions.
- Consider professional pest‑management services if the problem persists despite DIY measures.
After treatment, continue to observe the skin for delayed hypersensitivity reactions, which can appear up to 48 hours after the bite. Over‑the‑counter antihistamines (e.g., cetirizine, loratadine) may be taken according to package directions to control itching.
Finally, maintain preventive habits: keep indoor humidity low, trim grass around the home, and regularly inspect pets for fleas. Consistent vigilance reduces the likelihood of future bites.
