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 praying Bed Bug. Bed Bugs inject a substance that prevents the clogging of blood flow. This substance may cause skin reaction in some people’s skin.
The reaction to a Bed Bug’s feeding varies from person to person. Some people may get very big hives and feel itchy whereas other may not have any reaction on their skin!
