We received a question from a reader a few days ago about a “worm on my tile floor near the front door.” He sent a picture of the worm by the front door, but it is slightly out of focus, so it is hard to see. The worm appears to have antennae, which means he isn’t finding a worm, but some sort of worm-like creature, perhaps a centipede or millipede. Below we explore these possibilities in more depth.
