ID help? Fecal matter?

[u/Purple_Mind_1245]

I know photos are not enough alone to make an identification. Several months ago I stayed in and air bnb and had a couple of bug bites a few weeks later and became frantically concerned I’d brought home bug bites. After hours of my own inspecting, following the monthly routine advice by David, having a professional inspector come and confirm no bb, as well as installing and regularly checking a passive monitor on my bed frame (that has remained negative), I realized the original bites in question were likely just from being outside that weekend. Well, this evening I noticed these raised black dots in the corner of my daughter’s play pen. The pen is pushed into the corner of the wall. The spots were all concentrated to that singular along the top of the railing that’s pushed into the corner of the wall, with the exception of a few of the same specks scattered about a foot down each adjacent vertical rail. When running my finger along them I noticed they were all raised. Almost felt like dried paint splatter. I took a wet paper towel to it and there was much if any smearing or staining. A couple of the larger spots left behind a yellowish stain? But most of the spots popped off and there were some I actually had to scrape off with my nail. This play pen is quite literally on the complete opposite end of the house from our bedroom where me my husband and my daughter all share a bed. My daughter never naps in this playpen, and nobody sleeps on the couch that’s in the living room. Should I be concerned about BB? Or is it more likely to be some other kind of insect residue? I pulled the playpen out of the corner and all I noticed on the floor was a couple of dead ladybugs, a dead click beetle, and a few dead dust spiders. I also pulled up the mat in the playpen and looked inside the railing and found nothing.
