How to treat itchy bedbug bites? - in detail
Bedbug bites often cause intense itching and skin irritation. Effective management begins with immediate skin care, followed by symptom control and prevention of secondary infection.
First, cleanse the affected area with mild soap and lukewarm water. Pat dry with a clean towel; avoid rubbing, which can worsen irritation. Apply a cold compress for 10–15 minutes to reduce swelling and numb nerve endings, repeating every hour as needed.
Second, address the itch directly. Over-the-counter antihistamine tablets (e.g., diphenhydramine, cetirizine) taken according to package directions can block histamine release. Topical corticosteroid creams (1% hydrocortisone) applied thinly two to three times daily calm inflammatory response. For severe pruritus, a prescription-strength steroid may be required; consult a clinician.
Third, protect the skin from bacterial invasion. If lesions break, cover them with sterile gauze and use an antiseptic ointment such as bacitracin or mupirocin. Change dressings daily and keep nails trimmed to limit self‑inflicted trauma.
Fourth, limit scratching. Wear loose clothing, use mittens at night if necessary, and consider a barrier cream (e.g., zinc oxide) to reduce friction.
Fifth, monitor for signs of infection: increasing redness, pus, warmth, or fever. Seek medical attention promptly if any develop, or if the bite reaction persists beyond a week despite self‑care.
Finally, eliminate the source. Conduct a thorough inspection of bedding, mattress seams, and furniture. Wash all linens in hot water (≥60 °C) and dry on high heat. Vacuum carpets and upholstery, then discard the vacuum bag. Consider professional pest control for persistent infestations.
By following these steps—cleaning, antihistamine use, topical steroids, infection prevention, and source eradication—itch from bedbug bites can be effectively controlled and complications avoided.
