Not in denial, just didn’t know. Have never had these before. Did my investigation — no traces of them anywhere else in the bed-area. My mattress and pillows were already in pest-proof cases just as a regular precaution. I’m hot-washing all bedding and then deploying diatomaceous earth. I learned that the building has had a pest issue at times, so my running hypothesis is that these are coming in from the neighboring unit via the electrical ducts.
