Well, my matress and bed springs looked nothing like those in the pictures in that link. But I'll go over the area again with a fine tooth comb.

"Unlike cockroaches that feed on filth, the level of cleanliness has little to do with most bed bug infestations. Pristine homes, hotels, and apartments have plenty of hiding places and an abundance of warm-blooded hosts. Thus, they are almost as vulnerable to infestation as are places of squalor."

grrr...

Fingers crossed that it is not bed bugs.
