Bed bug bites appear as very itchy welts in a cluster of three to five spots. These spots can form a zigzag pattern on the body. There may also be tiny spots of blood on the person’s bedding.
Usually the welts will be surrounded by clear edges. They may look similar to bug bites, but hives generally will appear and disappear more quickly. They may itch, sometimes severely, and they’re not always the same size or shape. They may be as small as the tip of a pen or as large as a dinner plate. (4) When you press the center of a hive bump on the skin, it likely will turn from red to white, which is known as blanching. (2,3)

Hives, known in the medical world as urticaria, are your skin’s reaction to histamine (a chemical released by the body’s immune system in response to an allergen) and other inflammatory signals being released into your bloodstream. (1 )
Hives tend to resolve within a few days. To relieve the itching, apply a cold washcloth to the area or use an anti-itch cream. Try not to scratch the hives and avoid things that trigger the hives.
Scabies needs to be treated with a prescription from a healthcare provider. Not only does the person who has scabies need to be treated, but so does everyone who lives with or has sexual contact with the person.
