A bed bug bite generally appears not alone, but in groups of three, since one bed bug can bite you multiple times over the course of one night. This pattern of three is commonly called "breakfast, lunch and dinner" bites. Appetizing, right? (See pictures to help you identify a bed bug bite.)
A bed bug can bite you on any part of your body, but will generally go for exposed skin. Wearing extra clothes to bed can help protect you from a bed bug's bite.
A bite from a bed bug will look different on everyone, making them difficult to identify. Even doctors often diagnose them as a rash, since many people have an allergic reaction to the bite of a bed bug and break out in red, inflamed, itchy skin. Some people will have raised bumps wherever they were bitten; others will just have a generalized red area. In most cases, the bed bug bite will itch like crazy.
How long the bed bug bite will stay on your skin is also highly variable depending on the person. Those who are most allergic will take the longest to clear up, up to a few weeks. For others, the bed bug bite will clear up in a matter of days. It's important not to scratch the bite, as it could become infected and leave a scar. See Treatments for Bed Bug Bites
