A reader wrote to us via the All About Worms Facebook page to ask us about some small red worms that she recently found on her bedroom wall. The worms appear to have a cocoon or shell, or perhaps they just shed their skin (the reader mentioned all three as possibilities). The worms also seem to be legless and hairless. The reader reports that she has seen the small red worms before when she was younger; they were generally under stuffed animals that were on the floor, and again she noted that they seemed to leave behind their molted skin. In light of their repeated appearance in her life, our reader wants to know what the small red worms are, if they are even worms at all.
