How should bites from a bedbug be treated? - in detail
Bed‑bug bites typically appear as small, red, itchy papules that may develop a central punctum. Reactions vary; some individuals experience only mild irritation, while others develop larger wheals or secondary infection if the skin is scratched.
Immediate care focuses on reducing inflammation and preventing infection. Clean the affected area with mild soap and lukewarm water. Pat dry, then apply a cool compress for 10–15 minutes to diminish swelling and relieve itching. After drying, a thin layer of a topical antihistamine or a corticosteroid cream can be applied to control pruritus.
Systemic medication may be warranted when multiple bites cause widespread discomfort. Oral antihistamines (e.g., cetirizine, diphenhydramine) taken according to label instructions alleviate itching. Non‑steroidal anti‑inflammatory drugs (e.g., ibuprofen) reduce pain and inflammation. For signs of bacterial involvement—redness spreading beyond the bite, pus, or increasing warmth—apply a topical antibiotic ointment (e.g., bacitracin) and consider oral antibiotics prescribed by a clinician.
Medical evaluation is required if any of the following occur: severe allergic reaction (difficulty breathing, swelling of lips or tongue), extensive cellulitis, or persistent symptoms beyond a week despite self‑care. A healthcare provider may prescribe stronger corticosteroids, prescription‑strength antihistamines, or a short course of oral antibiotics.
Prevention of future bites reduces the need for repeated treatment. Regularly inspect sleeping areas for live insects, shed skins, or fecal spots. Wash bedding in hot water, dry on high heat, and vacuum mattresses and surrounding furniture. Encase mattresses and box springs in zippered covers designed to trap insects. Declutter rooms to eliminate hiding places, and consider professional pest‑control interventions when infestations are established.
