How to treat bites from bedbugs and fleas? - in detail
Bedbug and flea bites produce itching, redness, and sometimes swelling. Immediate care focuses on symptom relief and preventing infection.
Cleaning the affected area reduces the risk of bacterial entry. Wash with mild soap and lukewarm water, then pat dry. Applying a cold compress for several minutes eases inflammation and pruritus.
Topical agents provide additional relief:
- Hydrocortisone 1 % cream, applied two to three times daily, diminishes redness and itching.
- Calamine lotion, applied as needed, creates a soothing barrier.
- Antiseptic ointments containing bacitracin or mupirocin protect against secondary infection.
Systemic medications may be required for extensive reactions:
- Oral antihistamines such as cetirizine 10 mg or diphenhydramine 25 mg, taken every 12 hours, control widespread itching.
- Non‑steroidal anti‑inflammatory drugs (ibuprofen 200 mg) reduce pain and swelling.
- In cases of severe cellulitis, a short course of oral antibiotics (e.g., cephalexin 500 mg three times daily) is indicated.
Avoid scratching to prevent skin breakdown. If lesions develop pus, crust, or enlarge rapidly, seek medical evaluation promptly.
Prevention limits future bites. Regularly wash bedding in hot water (≥ 60 °C) and dry on high heat. Vacuum carpets, mattresses, and upholstered furniture, discarding vacuum bags immediately. Use encasements designed for bedbug containment on mattresses and box springs. For flea control, treat pets with veterinarian‑approved products and maintain clean indoor environments.
Monitoring the bite sites for changes—such as increasing size, fever, or lymph node swelling—ensures timely intervention.
