Hi there… I hope you can help identify this creature in my bathroom… It’s only seen in my bathroom. It freaks me out. Please help identify this.
About 1.5cm long. Has a leaf shaped soft shell it can crawl out from both ends.

Case Bearing Moth Larva

Case Bearing Moth Larva

Dear Sandra,
The Case Bearing Moth Larva or Household Casebearer,
Phereoeca fallax, is a common household pest that is found in many parts of the world.  You individual has a very distinctly marked case.  According to BugGuide:  “The larval case is silk-lined inside and open at both ends. The case is constructed by the earliest larval stage (1st instar) before it hatches, and is enlarged by each successive instar. In constructing the case, the larva secretes silk to build an arch attached at both ends to the substrate. Very small particles of sand, soil, iron rust, insect droppings, arthropod remains, hairs and other fibers are added on the outside. The inside of the arch is lined exclusively by silk, and is gradually extended to form a tunnel, while the larva stays inside. The tunnel is closed beneath by the larva to form a tube free from the substrate, and open at both ends. After the first case is completed, the larva starts moving around, pulling its case behind. With each molt, the larva enlarges its case. Later cases are flattened and widest in the middle, allowing the larva to turn around inside.”  The bold black and white spiral pattern on your individual’s case is likely due to fibers that were incorporated in the making of the case.

I have no idea what this bug is. I’m pretty sure they’re falling out of my roof through the fan in my bathroom.
It doesn’t necessarily look like a bug but they do move.
It’s about as long as a thumb nail and looks like a dirty bit of roof insulation.

Dear TC,
We can’t imagine that this is anything other than a Case Bearing Moth Larva, though it looks different from individuals we are used to seeing, perhaps because it is using distinctly Australian building materials.

Dear Mr. Marlos:
I found the attached, tiny cocoon-like item in my sink (of all places) the other day. When i pressed on it, out came the pictured worm. I don’t know whether to be sorry that I interrupted its chrysalis sleep or not. I suppose it depends on whether it was destined to be a beautiful butterfly or a garden pest. Can you help me to (hopefully) alleviate my guilt?

Dear Mr. Kulkis,
How nice to hear from you.  This is a Case Bearing Moth Larva and it is a common household intruder.  We have one amazing image in our archives of a pack of Case Bearing Moth Larvae eating a dog biscuit.

Indian Meal Moth

Subject: What kind of moths are these?

My girlfriend has been finding a bunch of these (what I believe to be) moths in her bedroom; one night, she encountered 10. To me, they resemble Indian Meal Moths. We typically find these at night, but that might just be a coincidence as we’re at work during the day.
We’ve never seen them flying around; whenever we turn on the lights, they just don’t move.
The door to the bedroom is right next to the entrance to the kitchen, which led me to believe that they were Indian Meal Moths, but there are no moths in the kitchen.
Thank you very much for your time and I look forward to your response.

Dear AG,
Clean out the pantry, paying especial attention to grain products and nuts.  You have Indian Meal Moths and the Caterpillars are eating your stored dry goods.

Good Morning, Please see photos of bugs collected from carpet with rice like cocoons?? Can you identify what the bug is and what the rice bits are. There are areas of carpet which have clearly been eaten and we need to identify the problem.
Many thanks

Case Bearing Clothes Moths and Woodlice

Casemaking Clothes Moths and Woodlice

Hi Ashley,
The “bugs” are Woodlice or Pillbugs, and though they might be a nuisance indoors, they are not eating your carpet.  They are attracted to damp conditions.  The rice like cocoons appear to be the cases of Casemaking Clothes Moths,
Tinea pellionella, a species that will eat wool rugs and clothes and we believe that is the source of the damage.  According to BugGuide, the larvae feed on:  “Feed on wool, feathers, fur, hair, upholstered furniture, leather, fish meals, milk powders, lint, dust or paper.”  The larvae, not the adult moths, are responsible for the damage.  It appears that one of the cases in the center of your “collection” is a different species in the same family, a Household Casebearer Moth case, Phereoeca uterella, which according to BugGuide:  “feed on old spider webs; may also eat woolen goods of all kinds if the opportunity arises.”  BugGuide also notes:  “Larval cases can be found on wool rugs and wool carpets, hanging on curtains, or under buildings, hanging from subflooring, joists, sills and foundations; also found on exterior of buildings in shaded places, under farm sheds, under lawn furniture, on stored farm machinery, and on tree trunks.”

Many thanks really helpful
Regards,
Ashley

Thanks so much for your extremely helpful site!
I’ve read your identification responses for both the Indian meal moths and the case bearing moths. I was wondering if the Indian Meal Moths also make the flat pods. I have found worms, cases and moths in my house for months now.
We moved to Puerto Rico from Maryland and I believe we unpacked the pests after they sat in a shipping container for two months. We threw away everything that we thought was contaminated, but they seem to be back! Just wondering if all three are maybe the same thing or if we have two kinds of bugs.
Thanks for any help!

Thanks for the nice compliment.  You are probably thinking of the Case Bearing Moth Larvae which are different than the Indian Meal Moths.
