They seem to spin some kind of silk everywhere they go. They seem to be no longer than about 4 mm. I noticed them crawling up things and then dropping down on a line of silk. I’ve started catching them by putting little sticks up in the air attached everywhere that I find them. They tend to gather at the top of the stick for easy rapture by vacuum.
My first thought is that it looks like a house centipede. Not sure about if they can make silk though. They hunt other bugs in your house.
That was my first thought too but they don’t look like the larvae of how centipede since those usually have some longer hairs at the front and back.
