One of our readers discovered two worms in his bidet (which is a low oval washing basin) over the course of a few days. He asks what species these worms are, and if they are harmful for humans to be in contact with.
He sent a photo, but it is taken from so far away that we are having difficulty identifying any distinguishing characteristics. It is long, thin, and appears to be brown.
There are several worms or larvae that readers have discovered in their toilets and bathrooms, and a few of them are similar in appearance to the worm in this image. We can’t rule out these options without a better picture, so we will give our reader some potential answers to his question.
Our first and most promising thought is that this is an earthworm. Earthworms live outside in damp soil, but sometimes find their way into a home through leaky pipes or via other means. Earthworms can survive submerged in water, so discovering them in a toilet, shower, or even bidet is not unheard of! Earthworms aren’t harmful to humans, but if our reader continues to find these creatures he should contact a plumber to check his pipes for cracks, which could be the source of entrance for these worms.
Another thought is that our reader has found a bloodworm. Bloodworms are actually midge fly larvae, but they get their nickname from their vibrant red color. Like earthworms, these critters need moisture to survive and have been discovered in readers’ bathrooms before. Bloodworms are not harmful to humans, but their presence indicates that a midge fly has laid eggs, which are hatching into larvae.
Our final contemplation is that or reader has found a millipede. Millipedes also like moisture, and might find their way into the bathroom on a search for water if they get inside of a house. Since our reader found more than one of these creatures over the course of a week, we do not think he has found millipedes.
Finally, we do not think this is a parasite or a worm that came from the human intestine, but since we couldn’t make a firm identification based on the photo we wanted to mention this just to be safe. If our reader thinks these worms could have possibly come from himself or a family member, he should reach out to a doctor immediately.
To summarize, one of our readers found two worms in his bidet, which is next to his toilet. While we gave three suggestions about what these worms are, we think they are most likely earthworms.
