Tiny Brown Worms or Larvae in the Couch

A reader bought a used couch recently and found some tiny brown worms or larvae in it. More precisely, she found the worms or larvae in the lining of the couch, so they had evidently made their way fairly far into the piece of furniture. The reader at first thought she might have found bed bugs, but ruled this out because whatever she found doesn’t have an oval-shaped body like a bed bug. Rather, the creatures she found have more elongated bodies, albeit ones that are very short. She estimates that they are only a few millimeters long. Other relevant body features include darkened heads and some hairs, or “hair-looking things,” that stick out of the end of the creatures’ bodies. What type of worm or larvae did our reader find in her couch?

First, let’s take a look at the picture our reader submitted:

The picture is a little small, but you can still see it has a tannish or brownish body, and that one end of its body is darkened. If you look really closely, it appears that the hairs are extending from the darkened end of the creature’s body. This is, for the record, the posterior end of the larva’s body, so the darkened part is not actually the creature’s head, as the reader thought, but rather the last abdominal segments of its body.

Given that our reader found the All About Worms website, we are little surprised she also didn’t find one of the dozens of articles we have written about carpet beetle larvae, which is what we think our reader found. We seem to write about carpet beetle larvae about every other week, and if one were to click around at random in the archives, an article about carpet beetle larvae would come up sooner rather than later. We say this not to fault the reader, but to point out that what she found is quite common, and also that we have some experience answering questions related to carpet beetle larvae.

Like most non-scientific names, “carpet beetle” actually refers to several different species of beetle. Of course, these beetles are related, and so are their larva, but they don’t all look identical. In this instance, the reader’s situation pulls us in different directions as far as precise identification is concerned. What she found looks like a species that belongs to the Trogoderma genus, which are also called “Khapra beetles,” but the environment in which she found them, a couch, is more consistent with her finding of member of the Anthrenus genus, also known as “varied carpet beetles.” The former are known for being pests of stored grains, whereas the latter are what people tend to find in their homes eating various household fabrics, like those found in carpets and furniture. In truth, though, we are talking about fairly small differences, and the appearance of the larvae change as they mature into their adult forms, so it is hard to identify precise species.

So, we can’t be certain she found carpet beetle larvae, but we think there is a fairly good chance this is the case. We have written articles about how to get rid of carpet beetle larvae (this article also links to other good resources), and this may be of interest to our reader. Hopefully the problem is small and that the creatures haven’t taken over the couch. If they have, it might not be worth keeping the couch because you don’t want to introduce the larvae into your house via an infested piece of furniture. We hope our reader doesn’t have anything too serious on her hands, and also that she is able to address the problem easily and successfully.

    Ive had a weird silky squigly hair like strands all over my house .for 4 years now .and found a worm pinkish off marajuana .prob is im getting bit all over my body by something .and im finding these silky strands all over my clothes.idk.what to do..

  2. I was looking for a shoe in my closet and then I pulled a blanket out and then I saw the worm/larvae and it was tan and had a black head and moving. It was not dead. I killed it with a piece of paper. I am worried about if there are more or not. It did not have stripes though. I am scared of the outcome and when I saw it, I was cussing like a sailor. By this, you can tell that I hate bugs. What is it?

    I am finding these tiny brown worms everywhere. They are very small and dark on one end and lighter brown on the other with what appears to be stripes on the body. They are on kitchen counter top, tile floor in kitchen and bathroom. They always appear dead since there is no movement. I just found a few on a shirt in my beach bag. They are disgusting to look at and my small grandchildren get scared when they see them. I have very little areas covered with rugs and have mainly wood floors and tile floors. I am clean and wash my floors with ammonia and hot water. I need to know what to do about these creatures.
