What should you know about common places for bed bug bites?

Bed bugs feed while a person is resting, so marks may occur on skin that touches or extends beyond bedding. Spots can be scattered, grouped, or arranged in a short line, and itching may begin later rather than immediately. The appearance is not enough to confirm bed bugs: other bites, eczema, and contact reactions can look similar. Check the sleeping area for signs such as tiny dark marks or shed material, and consider a pest professional for confirmation.

Wash the skin gently, apply a cool compress, and avoid scratching. Keep nails short and cover broken areas with a clean dressing. A clinician or pharmacist may recommend [Antihistamine Treatment](/treatments/medical-dermatology/oral-antihistamine-therapy/) or [Topical Corticosteroids](/treatments/medical-dermatology/topical-corticosteroids/) when appropriate. Treating the environment matters too: inspect bedding and arrange professional pest control rather than relying only on skin creams.

Seek urgent help for breathing difficulty, facial or tongue swelling, faintness, or a rapidly spreading allergic reaction. Arrange a medical review if bites become increasingly painful, hot, swollen, or ooze fluid, or if fever develops. Persistent itching that disrupts sleep also deserves assessment, particularly when new marks continue despite environmental treatment.

Do these marks fit bed bug bites or another skin condition? Is an antihistamine or steroid cream suitable for me? How should I protect scratched skin, and what environmental steps should happen alongside treatment?
