“I have an infestation of white moving little things coming out of the corners of every room”, writes Debbie in her submission, which unfortunately does not include any photos. “They’re different sizes and very small and they stick to whatever they can and you can’t break them away from it. They also are in my neighbors house and all over her house counter tops and on her clothes. They can break apart and still live. Their texture is like a human being booger out if their nose. Please help if you know anything about this. Please respond.” We will say that we will not be able to identify this worm with 100% accuracy or certainty, given the lack of photo and how vague the physical descriptions are. All we can do is make some educated guesses.

“I found these worm-like critters living in my cat’s automatic waterer”, writes Linda about the black creatures pictured below. “What are they and where did they come from?” Based on the excellent photo and the context that Linda provided us, we think she found drain fly larvae in the waterer. Drain fly larvae are harmless to humans and cats, but can be quite a nuisance. As their name suggests, they are found near or inside drains, as the adult flies lay their eggs on the organic film that forms in the lip of a drain. They do this because the diet of the larvae largely consists of the organisms that grow in stagnant water, like algae and fungi, as well as microorganisms.

“These teeny tiny worm-type things have suddenly appeared in our baby’s cot!” writes Kristin in her submission regarding the segmented creature with the bulbous head pictured below. “They look like bits of dirt initially, but when we looked closer they are moving! Could they be inchworms? And is this common in a babies cot? Thank you.” Based on the great photo Kristin sent in, as well as her keen eye for caterpillars, we can confirm that this is indeed an inchworm. Firstly, and most importantly, inchworms are not harmful to babies, or to grown adults for that matter. They are caterpillars of moth species which are endemic to North America, and they are characterized by the placement of their legs (at the front and back) which makes them arch their back as they walk.

“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.

“Can you please help identify this worm?” asks this reader in their submission regarding the white and yellow-striped worm-like critter pictured below. “Thank you. I really appreciate it.” Well first off, we want to say thank you to our reader for sending in this great photo! To us, this looks like a caterpillar of some kind, though we are not entirely sure what species of caterpillar it is. It could also be a sawfly larva, which are often mistaken for caterpillars. What we will say is that we recommend that our reader avoid direct physical contact with the creatures, since we do not know what they are. Allergic reactions can occur with unknown species. We do not think it is highly likely with this caterpillar, as typically poisonous caterpillars possess bristles, but that is not always a given.

“In February we moved into a new house that we had just renovated, and in April we started seeing small larvae like pests showing up in our bedrooms, kitchen, bathrooms”, writes Jill in her submission regarding the small, segmented creature pictured below. “They are tiny and only noticed them because they were crawling up the wall/ceiling. Our pest company identified them as carpet beetles stemming from our attic. They have been coming down, inside the walls and I’ve treated those areas, as well as spraying inside and outside the home. We saw many die off over the next few weeks, and then they seemed to go away until July when they came back. I’ve never seen a beetle. We live in Colorado at 7,000 feet elevation. I’ve found them on all three levels of our house in every room. We do have large spruce trees near the home. A new pest company came and (with my help) identified them as duff millipedes. I would love this to be the case and would be interested in a second opinion. Photos and video attached.”

“I am from Ohio and have seen this near the dog’s bowl am not sure if it is a worm or just mucus”, writes Santos regarding the white, worm-like object pictured below. “This is the only one I have seen. Thanks.” We are with Santos on this one: we are not sure if this is a worm either. It has qualities that remind of us worm-like organisms we have seen before, including a darker, circular bit that looks like a head, somewhere around the middle of the body. Obviously, that’s not where heads go on an animal, so this had us thinking this might be two worms rather than one, if it is a worm at all. In any case, it definitely looks suspicious for mucus, so we understand why Santos is concerned.

“I found these in our toilet after five days of no use”, writes Cindy about the swarm of black worm-like creatures pictured below. “One of my grandchildren used the toilet last. Could these be pinworms?” First and foremost, we have to make clear that we will unfortunately not be able to confirm or deny if these are pinworms. For context, pinworms are parasitic worms that situate themselves in the intestines of their hosts. They are very common in children, so we understand Cindy’s concern, especially since these were found in a toilet. However, we are not qualified or legally able to identify parasites, given that their presence indicates a medical situation. Only a medical professional is able to identify such organisms, as that identification acts as the diagnosis which determines what kind of treatment may or may not be needed for the person afflicted.

“I keep finding these worms in my bathroom,” writes Chase in his submission regarding the long, thin worm pictured below. “First two times I was in the shower, then by my sink. I see them only on the walls. What are they? I am in Arizona.” The photo is somewhat blurry, so we cannot make out the finer details of the worm’s physical characteristics, but based on what we can see, as well as the fact that it is climbing Chase’s walls, we think this could be a flatworm. Generally speaking, flatworms are predatory creatures. We say generally speaking because there are thousands upon thousands of flatworms species and a good portion of those are parasites. Not to worry, most flatworm parasites cannot survive outside the body of a host, so when someone finds a flatworm in the wild, 99% of the time they will be a predator.

Welcome to the next installment in the earthworm series. This is the second in a set of three, which aims to provide a brief overview of some of the most notable and often-discussed species of earthworms. If you have not read the first article, we covered the common earthworm and the tiger worm in that one. In this sequel, we will be looking at pheretima earthworms and the Asian jumping worm. These two species are pretty well-established in the helminthology world, though sources on the pheretima earthworm seem to provide conflicting accounts about their physical characteristics.

“What kind of bug is this?” is all Kimberly asks in her submission regarding the dark gray-brown-colored organism pictured below. She does not include any context with her submission, and we do have to note that the resolution on the photo is poor, meaning that when we zoom in on the creature, the details become incredibly blurry. With that in mind, it will not be possible to provide an identification which is 100% accurate; the identification we are about to make is based purely on an educated guess we made, which is, in turn, based on the little we can make out from the photo.

“Can you help me identify what this thing might be that I found on my bathroom counter?” asks Linda in her submission regarding the photo she sent in below. “Sincerely appreciate your time and effort.” We were not sure what she was referring to in the photo below. There are some black, hair-like objects, as well as a red, lint-like object in the photo. But since Linda refers to the “thing” in the singular, we are going to assume she means the red thing. In our opinion, this does not look like an organism, but just like a piece of lint, but that could be because the photo is so blurry that the details of the organism’s identifying features are muddled, making it look like a piece of lint. Regardless, since the photo is as blurry as it is, we will not be able to provide a confident or accurate identification.

“I’ve been stumped after finding this creepy bug in my bathroom”, writes Kristina in her submission regarding the stick-like object pictured below. “I realize this isn’t a worm, more like a walking stick. And they bite! Notice the strange head.” Now, we do not know which end of the organism is the head, as it is not clear just from the picture since the organism does look exactly like a stick. We also do not know which of the two twigs is meant to be the organism, though we would assume it is the thinner one since the bigger one clearly has a splintered end (which would not be possible if it was an organism). If it was not for Kristina telling us that this was a bug, we would not have been able to tell. We will do our best to help Kristina arrive at an identification, but we must say that we will not be able to provide an accurate or confident identification, given that we are not insect experts: we specialize in worms and worm-like critters.

“Can you help me identify what type of caterpillar this is?” asks Suzanne in her submission regarding the caterpillar pictured below. “I live in Fredericksburg, Virginia. And it was resting in a cottonwood tree. It measured about five inches long. Thank you!” Firstly, we have to compliment Suzanne on the gorgeous photo. The lighting, colors and detail are just incredible, and are very helpful to us in identifying this creature. Suzanne is absolutely right in identifying this as a caterpillar. Specifically, it is an ilia underwing moth caterpillar. Underwing moths are a genus of moth that is characterized by their colorful under wings which contrast the otherwise neutral or bland colors on their top wings.

“I’m based in the UK and found this in my bathroom”, writes Angela in her submission regarding the grayish, ovate creature pictured below. “I’ve found three so far and cannot find out what it is. My bathroom has a ledge away from the water source; one was found wiggling on the tiled ledge, and one was in an even more curious location: inside a clean container with some serialized items. The one pictured came from a plastic tray which I was cleaning out and, to be fair, this tray was quite dirty and had a pattern with ridges. It was about 4mm in length and didn’t appear to mind water. Is it a drain fly larva? I’ve posted how it moved on Reddit, linked below. Many thanks!” To start with, we have linked the video below that she posted on Reddit, and it is quite an interesting video. It looks like the organism is underwater, and yet the way it contracts its body and moves forward looks like it is dragging itself across a solid surface, rather than swimming.

“Is there a worm that can live off of fabrics as well as wooden structures?” asks this reader in his submission. “I’ve been seeing damage to wooden furniture as well as drywall and fabrics in our home. There’s also a dramatic increase in the quantity of dryer lint produced when I do laundry. Like I mean an extreme amount. Our clothing and bedding is riddled with holes and loose threads hanging down. There’s also strange markings on walls and ceilings (etc.) that I can’t explain. These weird fuzzy web looking things that appear to be growing out of the wall, I don’t know? Do we have some sort of house pest or is there something else contributing to these issues? I’ve been searching for answers and coming up empty. Any insight would be greatly appreciated. Thank you.”

“I found this guy in Lloydminster, Saskatchewan, Canada. What can I feed him?” writes this reader about the stick-like worm pictured below. At first, we did not see what our reader was referring to. We thought it was just one long branch. But then we noticed that the twig-like object on the right did not exactly match the rest of the branch, and does look like a separate entity. We think this is a stick caterpillar, which is a larva of the peppered moth. They are not the same things as stick insects, which are not worms or larvae of any kind, but a completely different species.

“I pulled this off my cat”, writes this reader in her submission regarding the brown, slimy-looking, worm-like creature pictured below. “Can you identify it?” For starters, we will say that, while we will provide an identification, it should not be taken as 100% accurate or certain. The primary reason for this is because our reader pulled it off our cat. Any worms that are found on or inside people or pets pose a potential medical situation. Since we are not medical professionals, we are neither qualified or legally able to identify organisms that directly affect the health of people or pets. In this case, it is not clear whether or not the worm is affecting the cat’s health: people and pets accidentally get worms on them all the time, just from going outdoors. For that reason, we err on the side of caution. If our reader suspects that this worm may have come from her cat, or that it is in any way negatively affecting her cat’s health, she should consult a vet about it and disregard our identification below.

“I have found these dead worm/snake-like critters on my patio and a few in my pool,” writes Hailey in her submission regarding the black and brown, worm-like creature pictured below. “There are around 20 of them and they are freaking me out. Any idea what it is? I’m in the Dallas/Fort Worth Texas area. Thank you.” Right off the bat, we can tell Hailey that this worm is dried up: you can tell by its shriveled body. The worms could have died another way but dried up afterward, but given what we know these to be, we think it is likely they died from the heat itself. Typically, we would not be able to identify worms that were dried-up, as their physical characteristics can change quite drastically, making them much harder to identify, but in this case, we have seen so many of these worms in this state that we know what they are.

“I live in southern Ontario and I noticed these little guys roaming around my apartment (see picture)”, writes Rachel in her submission regarding the tiny, black, worm-like creature pictured below. “Just wondering if I should be concerned. They seem to just crawl on my floor, the side of my mattress, and on my clothes. I’ve washed everything and swept and mopped the floors, but it’s tough to get them all. I’m just hoping they don’t turn into moths in a couple of weeks if I missed one. I’m pretty clean to begin with (as I live in a small studio) so I’m really puzzled where they came from. Thanks!”
