A reader wrote to us recently about “a light brown worm-like creature in the bath tub.” We are basically certain the worm-like creature is a larva (or actually larvae since he found several), so we’ll stick with that usage throughout. The larvae have only been found inside the bath, and they are only observed on occasion (i.e., not every day). The larvae are segmented, and they appear to have antennae and hair on their body. What is our reader finding in his bathtub?
