“We found these worms in one of our toilets after returning thirteen days later”, writes Jerry in his submission regarding the many, tiny, black, worm-like creatures pictured below. “No one used this toilet while we were gone. This toilet is on the second floor.” Considering the worms’ appearance and the context in which Jerry found them, we think he has found drain fly larvae. Also known as moth flies due to their stout, furry bodies which resemble moths more than the common house fly, drain flies are notorious bathroom pests. They are not pests so far as doing any real damage to the items in one’s home, but infestations of them can be hard to tackle and the flies can thereby become a real nuisance.
“I returned from a holiday to find these worms swimming in our toilet”, writes Siobha about the black creatures pictured below. “What are they?” We have to admit that, were it not for the size and color of the worms, as well as the location they were found in, we would not be able to identify these creatures based on the photo and video alone, because the quality is simply not that good. Fortunately, we can make an educated guess based on the aforementioned factors: we think these are drain fly larvae. As their name suggests, drain fly larvae are the immature form of a species of fly that like to infest drains. They are not harmful, but they can be quite a nuisance.
“What are these brown worm-like bugs in my toilet?” asks AnnaMarie in her submission regarding the two, segmented creatures pictured below. She offers no further context, and, unfortunately, the lighting is not the best, and it is hard to make out the organisms’ finer characteristics. That said, based on their shape – particularly the little tapered tip at one end of its body – we think that these might be black soldier fly larvae. How these two critters would have come to show up in AnnaMarie’s toilet is a mystery to us, as black soldier fly larvae are not typically found in this spot.
Dark Brown Worm Found in Toilet May Be a Drain Fly Larva, Though Concerns About Parasites are Raised
“What are these worms and should we be worried?” asks this reader, who is worried that the worms are inside her and the people who have used the toilet. The creature, who was found “swimming in [her] toilet”, seems to be a dark-brown color, with a brighter, yellowish tail/head (though it is difficult to tell).
A reader has been finding black worms in his toilet over the last couple of months. The worms in the toilet (we should actually say worm in the toilet, as only one is ever found at a time) appear seemingly out of nowhere, and they do not appear to be linked to anybody using the toilet. (In other words, the worms aren’t coming from somebody, which is good.) What are these black worms in the toilet? Is our reader finding a type of worm at all, or might he be finding some kind of larva (or larvae, since he’s found five)?
