“I’ve been searching for an answer to what this worm is, since I’ve been seeing it sometimes since a few weeks ago”, writes Martin in his submission regarding the red worm pictured below. “I’m from Montevideo, Uruguay, and I found only three or four of them since I’ve started seeing it, this being the longest (like 25-30 mm). I’m worried because I don’t know a lot of worms (they disgust me) and I don’t know where they come from, but from reading some of your posts and comparing photos, it looks like a bloodworm. Still, I want a professional opinion. I found one in the bathroom sink, another one on the bathroom floor, and the third one, believe it or not, was up on the bathroom wall, close to the ceiling and the little bathroom window. The fourth one was down on the wall close to the floor and close to my house entrance; all of this in the duration of almost a month or so.
