If fleas bite, how should they be treated? - in detail
Flea bites produce small, red, itchy lesions that may develop into inflamed papules or hives. Immediate care focuses on alleviating discomfort, preventing secondary infection, and eliminating the source of infestation.
Topical treatment begins with cleansing the affected skin using mild soap and lukewarm water. After drying, apply an over‑the‑counter antihistamine cream or a corticosteroid ointment to reduce inflammation and pruritus. For individuals with sensitive skin, a calamine lotion or a 1 % hydrocortisone preparation provides comparable relief without systemic effects.
Systemic antihistamines, such as cetirizine or diphenhydramine, may be taken orally to control widespread itching, especially when multiple bites are present. Dosage should follow package instructions or physician guidance.
If signs of infection appear—purulent discharge, increasing redness, warmth, or fever—prompt medical evaluation is required. Antibiotic therapy may be prescribed based on culture results or clinical judgment.
Addressing the underlying flea population prevents recurrence. Effective control includes:
- Vacuuming carpets, upholstery, and pet bedding daily; discarding vacuum bags immediately.
- Washing pet bedding, blankets, and removable covers in hot water (≥ 60 °C) and drying on high heat.
- Applying a veterinarian‑approved flea preventative to pets, such as a topical spot‑on treatment, oral medication, or a collar containing insecticidal agents.
- Treating the home environment with an insect growth regulator (IGR) spray or fogger that targets flea eggs, larvae, and adults; follow product safety directions carefully.
After environmental and pet treatment, monitor the skin for residual lesions. Persistent itching beyond two weeks warrants dermatological assessment to rule out allergic dermatitis or other skin conditions.
