May be it would be more accurate to see these bite marks as someone’s skin’s reaction to the injection of anti-coagulant saliva by a preying Bed Bug. Bed Bugs inject a substance that prevents the clogging of blood flow.
This substance may cause an allergic skin reaction in some people’s skin.
The reaction to a Bed Bug’s injecting the anti-coagulant secretions varies from person to person. Some people may get very big hives and feel itchy whereas, up to 30%, others may not have any reaction on their person!
