Bedbug bites are normally arranged in a cluster or line and appear red in color. Often a darker red spot is in the middle of the bite. Normally bedbug bites occur on the face and neck area as well as the arms and hands, according to Mayo Clinic.
Some people are very allergic to bedbug bites and experience blisters or hives, while other people do not have a significant reaction. Signs of bedbugs include blood smears on bedding, dark specks on mattresses, and tiny, light-brown exoskeletons that are left behind when bedbugs molt. Bedbugs are notoriously difficult to get rid of and are capable of living for months without eating, explains Mayo Clinic.
