“I went to take a bath before work and felt something moving on my knee”, writes this reader about the white, worm-like creatures pictured below. “I grabbed it, thinking nothing of it and it started squirming in my fingers. I found 11 of them in the water with me, and I clean my tub before every bath I take. My boyfriend later that night took a bath, and not a single sighting of one, and I extensively looked! It was small, short, and white with a brown head. Is it me who is infected or my water?” To begin with, we think our reader found some kind of insect larva in her tub, as that is what these most resemble. What species in particular is hard to say, as a white body with a dark head is about as generic a description as you can find of an insect larvae: beetles, moths, and flies all share larvae that fit this description.
