Entomologist Dr. Lou Sorkin of the American Museum of Natural History has told me he thinks bed bugs smell like coriander. And he has had a lot of time to ponder this: in addition to going on bed bug calls, he has a colony of bed bugs living in a jar in his office.
These signs include: 1  the bed bugsâ exoskeletons after molting, 2  bed bugs in the fold of mattresses and sheets, 3  rustyâcolored blood spots due to their blood-filled fecal material that they excrete on the mattress or nearby furniture, and.  a sweet musty odor.
