The bed bug species that is infesting homes today are the descendents of cave dwelling bugs that originally fed on bat blood. When humans began living in the caves (100,000 to 35,000 years ago, depending on the source), the bugs began feeding on humans. Later, when humans moved out of the caves and started their agricultural civilizations, the bugs moved with them. Since that time, humans have carried bed bugs all over the world.
