I woke up the other morning with 5 little itchy dots under my arm. Well, Google research over the last 48hrs on what kinds of bugs bite in a line eventually brought me here. I stripped and closely searched my entire mattress, box spring, frame, and headboard. I have found NOTHING live or dead. Except once small area on the corner of my box spring that makes me nervous. Can anyone confirm either the bites or the spot on the box spring? I’m planning to treat anyway, but some confirmation would make me feel better.
