A reader wrote to us a few days ago to ask about some tiny worms he found coming out of what appears to be his shower drain. (The reader said the worms came out of his “water floor trap,” but based on the pictures he submitted, we are pretty sure this means the worms are in and around the shower drain.) The reader said the worms look like earthworms, but are “very tiny,” and indeed they are, as you’ll see in a moment. Naturally, the reader was curious what he found, so he submitted some pictures to us for “analysis,” asking us to identify the tiny worms in the drain if possible.
