What to do when fleas bite you? - in detail
If a flea lands on your skin and bites, begin by cleansing the site with mild soap and lukewarm water. This removes saliva and reduces the risk of secondary infection. Pat the area dry and apply a cold compress for several minutes to lessen swelling and numb the itch.
Next, treat the irritation. Over‑the‑counter hydrocortisone cream or calamine lotion can be spread thinly on the bite. Oral antihistamines such as diphenhydramine or cetirizine help control histamine‑driven itching and swelling. If the reaction is severe, a short course of a prescription antihistamine may be warranted; consult a pharmacist or physician for guidance.
Avoid scratching. Repeated trauma can break the skin, introducing bacteria and leading to cellulitis. Keep fingernails trimmed and consider wearing a light bandage if the urge to scratch is strong.
Observe the bite for signs of infection: increasing redness, warmth, pus, or expanding swelling. Fever or a spreading rash also warrants prompt medical evaluation. Seek professional care if any of these symptoms develop.
Address the source to prevent further incidents.
- 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 (≥ 60 °C) and dry on high heat.
- Treat companion animals with a veterinarian‑approved flea control product; repeat according to the label schedule.
- Consider an environmental flea spray or fogger for heavily infested indoor areas, following manufacturer instructions and ensuring proper ventilation.
Maintain regular grooming of pets, keep lawns trimmed, and limit wildlife access to the home to reduce the flea population over time.
