What should you know about getting rid of bed bug bites?

Bed bug bites can cause itchy red bumps or grouped marks, but skin reactions vary and may appear after a delay. The appearance alone cannot confirm the insect. New lesions may continue if bedding, furniture, or luggage remains infested. Scratching can break the skin and allow a secondary infection.

Wash the area gently, apply a cool compress, and keep nails short. Avoid scratching and avoid applying harsh household chemicals to skin. A clinician may recommend [Topical Corticosteroids](/treatments/medical-dermatology/topical-corticosteroids/) for inflammation or [Antihistamine Treatment](/treatments/medical-dermatology/oral-antihistamine-therapy/) for itch, depending on your health and other medicines. Have the sleeping area inspected and treated by a qualified pest professional.

Seek medical care if bites become increasingly painful, warm, swollen, or drain pus, or if redness spreads. Emergency help is needed for breathing difficulty, swelling of the lips or tongue, faintness, or widespread hives. Children, pregnant people, and anyone with significant skin disease may need tailored advice before using medicines.

Ask whether the rash fits an insect-bite reaction, which product is safe for your age and skin, how long to use it, and how to recognise infection. Tell the clinician about pregnancy, allergies, and medicines you take.
