location . . . Bed bug bites are commonly found on the face, neck, arms, or hands, sometimes on other exposed areas of the body. As bed bugs are attracted to carbon dioxide these bite sites can be towards the top of the body when the host is lying down asleep.
appearance . . . . The bites usually presents themselves as a raised welt which usually occurs as the result of an allergic reaction. This reaction is due to the anaesthetic saliva of the bed bug which it injects into the host to prevent the blood from clotting as it takes a feed. This is often followed by severe itching and inflammation of the area a few hours later.
reaction . . . . Some people do not always react to the bite of a bed bug; this is usually because they have been bitten before and are de-sensitised to the bite. Other people can have an extreme reaction to a bite including severe hypersensitivity and asthmatic symptoms. Multiple bites are often aligned to your veins.
