What to do if a person is bitten by a flea? - in detail
When a flea pierces the skin, the immediate reaction is usually a small, red, itchy bump. Prompt care reduces discomfort and prevents secondary infection.
First, remove the insect. Use a pin or tweezers to extract the flea without crushing its body, which could release additional saliva. Discard the specimen in a sealed container for possible identification.
Next, cleanse the site. Wash with mild soap and lukewarm water for at least 30 seconds. Rinse thoroughly and pat dry with a clean towel.
Apply a topical antiseptic. Options include:
- 0.5 % povidone‑iodine solution
- 70 % isopropyl alcohol (use sparingly to avoid skin irritation)
- Antiseptic wipes containing chlorhexidine
If itching persists, use an over‑the‑counter antihistamine or hydrocortisone cream (1 %). Apply a thin layer no more than three times daily.
Monitor for signs of infection:
- Increasing redness or swelling beyond the bite margin
- Warmth to touch
- Pus or foul odor
- Fever or chills
Should any of these appear, seek medical evaluation promptly. A physician may prescribe oral antibiotics or stronger corticosteroids.
For individuals with known allergies to insect bites, carry an epinephrine auto‑injector and follow an emergency plan if systemic symptoms develop, such as hives, difficulty breathing, or throat swelling.
Prevent future incidents by treating the environment:
- Wash bedding, clothing, and pet fabrics in hot water (≥ 60 °C) and dry on high heat.
- Vacuum carpets and upholstery daily; discard the vacuum bag or clean the canister afterward.
- Apply a veterinarian‑approved flea control product to pets.
- Consider residual insecticide sprays or foggers for infested indoor areas, following label instructions.
Document the bite’s location, appearance, and any treatments applied. This record assists healthcare providers if complications arise.
