“I am finding these tiny dark brown worms all over my cubicle desk at my work”, writes Una in San Diego about the darkly-colored creature pictured below. “I’ve also found tiny worms in green also. I’m freaking out because I read on your post that they could be flea worms!? I do have dogs but I haven’t seen any worms like this at home. I live in San Diego, California.” The photo alone does not really help us much, unfortunately. Even when zooming in, the worm looks like nothing more than a black blob. Additionally, Una does not send any photos of the green worms she mentions.
