What should you know about cure for bed bug bites?

Bed bugs feed on blood and can leave itchy red bumps or small clustered marks. The skin reaction can appear after a delay, so new marks may be noticed after sleeping even when the bite happened earlier. Bites can occur on exposed skin such as the arms, legs, neck, or face. Scratching can break the skin and allow a secondary infection to develop; the bites themselves do not usually require a procedure.

Wash the area gently, use a cool compress, and keep fingernails short. An oral antihistamine may reduce itch; a clinician or pharmacist can help choose an appropriate option, especially for children, pregnancy, or other medicines. A topical corticosteroid may calm inflammation when suitable for your skin. Follow the product directions and avoid applying steroid cream to broken or infected skin unless advised. Wash bedding and clothing using heat that the fabric allows, vacuum mattress seams, and arrange professional pest control if bed bugs are suspected. Treatment for the skin will not remove the infestation.

Seek urgent help for trouble breathing, swelling of the lips or tongue, faintness, or rapidly spreading hives. Arrange medical assessment if the area becomes increasingly painful, warm, swollen, or drains pus, or if you develop fever. Persistent itch, widespread reactions, or uncertainty about whether the marks are bites also deserves a clinician’s review.
