A reader wrote to us recently about the small, black worms she is finding in and around her garage door at night. She claims to be finding “hundreds” of worms, so she is clearly having some trouble with these creatures. In addition to the adjectives small and black, the reader describes the worms as “round,” by which we think she means their bodies are cylindrical, or perhaps the creatures are curled up. If the entire bodies of the worms are round, one probably wouldn’t suspect them to be worms. As a matter of fact, though, our reader probably isn’t finding worms; rather, she seems to be finding millipedes, a common household pest. So, the small, black “worms” our reader is finding are in fact small, black millipedes, or so we posit.
