“What type of worm or larva is this?” asks this reader about the dark gray worm-like creature pictured below. “Found in the shower. Location in northern Alabama. Thanks!” To start with, we want to thank our reader for taking such a clear picture: it really helps us get a quick grasp on what the organism might be. In this case, we think this is probably a drain fly larva. Not only does its physical characteristics match that of a drain fly larva, but the location in which it was found also makes sense. As their name suggests, drain fly larvae are usually found in drains. This is because the mother fly will lay her eggs there, specifically on the thin film that forms in drains that are not regularly cleaned.
“From what I have read I think I may have drain fly larvae in my jacuzzi jets”, writes this reader in her submission regarding the organism pictured below. “They are dark brown and when looked at through a magnifying glass, they look like tiny millipedes. Can you please confirm? Thank you!” Immediately off the bat, can we say that these are indeed drain fly larvae: their long, thin dark bodies and tapered ends point to this conclusion. Likewise, the location they were found in matches up with the behavior of drain fly larvae.
“I keep finding these small caterpillar-like bugs in my bathroom”, states this reader in her submission regarding the bristly, brown worm-like creature pictured below. “Found two in the bathtub, one in the toilet and most just crawling on the tile floor.”
A man contacted us with reports of drain fly larvae latching on to his clothing and skin and causing all sorts of symptoms. He does not pose any questions directly, nor does he attach any photos, but we will relay his story nonetheless.
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).
“I found this on our water while I was filling the tub”, states this reader in her query concerning the black worm pictured below. She is not sure if they are leeches or something else, and wants to know if it is harmful.
“I have found cream colored maggots with brown heads two years in a row at this time of year in November,” says this reader. She does not provide photographs, but instead a decent amount of context that we will use to try and figure out how best to help our reader.
“If I do have moth larvae and you say to keep drains clean and of course dry, is cleanser adequate or do we need something super duper?” asks this reader in her query about “transparent worms” she has been finding in the kitchen and bathrooms. The creature in the photograph appears to be minuscule in size, a green/gray color, and has two rows of spots going down its back.
“EWWW!!!” says this reader upon finding larvae crawling up from the baking soda she put on a bathroom carpet in an attempt to clean it. The larvae in question are a gradient of colors, their bodies moving from white to dark gray, with a black tip on the lighter end. They also appear to be bristled, and from the video our reader sent it is clear that the larvae have no legs.
“We found these little tiny black worms in our bathtub and was wondering what they are,” states this reader in his submission. From the pictures he sent us, we can see that the worms look more brown than they do black, with horizontal stripes running along their bodies and dark tips at either end.
After leaving her house in South-East England empty for three months, this reader has found a worm in her toilet and wonders if we have any ideas about what it could be. The worm is described by our reader as having “yellow and reddish-brown stripes”, and zooming in on the photograph she sent us confirms, at the very least, that the worm is striped.
“Every once in a while I’ll find a maggot or 3 on the floor in the bathroom” says this reader. She asks us if we can tell her what to do, how to get rid of said maggots, and what might be causing them to appear.
“A few days before” removing black larvae from her living room ceiling, this reader “had seen a rather large, dark, furry moth.” She believes the larvae to be moth fly larvae (otherwise known as drain fly larvae), but wonders if this moth, which was an inch in size and width, was indeed a mother moth fly, or something else entirely.
Small, dark brown worms of about 0.6cm (roughly 0.2-inches) have been popping up in the bathrooms and kitchen of this reader’s townhouse. Our reader tends to find multiple at a time in the kitchen, but only one at a time in the bathroom, and has been finding these worms for about a year now.
What looks like small, black worms were photographed by this reader, who wonders if they are grout worms. The photographs display organisms with an array of various body shapes; there are small curled up bodies, long straight ones and the last photograph is of what simply looks like a black dot.
A woman recently contacted us about a moth infestation she has been experiencing over the past couple of months, and she asks for our help in identifying and dealing with the problem. She has herself identified the moths as pantry moths (Indianmeal moths) “because they have a stripe across their body”, but is now wondering whether or not they could be drain moths.
Little live black worms have been appearing in this reader’s shower, who has “cleaned & cleaned & cleaned” in an attempt to get rid of them, to no avail. She wonders if we can tell her what the worms are and how to get rid of them.
A reader of ours found two worm-like creatures in a toilet at an Air BnB and wonders if we have any thoughts as to what they might be. The creatures in question appear to be black and white in coloration, with a segmented body striped black and white, a sharply-pointed tail, and a bulkier head sprouting two antennae.
