What's That Bug? does not endorse extermination

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.

Yesterday I found a bug in the bathroom, a type I have never seen before. Since we occasionally have silver fish, I thought it might be an odd looking one. Then today I saw something move ever so slightly at the rug’s edge [an area rug in the den]. Closer checking and it looked just like the bug I found yesterday. I got a magnifying glass and tried to figure out what it might be. I spent the last 90 minutes searching the web as best I can. No luck. I’m as puzzled now as ever. I will attach a couple of photos, though not the best, but the best I could do.
The bug measures 5/8 inches by 1/4 inch. Color appears to me to be a tan or ivory and the head appears to be a redish color.
Any ideas?

Dear Daniel Marlos,
Bravo!
That was quick.  My thanks.  I have now checked it out with that title.  Must admit, I have never seen one before.
My sincere thanks!

Life is just simpler if you plow around the stumps.

Dear Charles,
Thanks so much for your kind response to our terse identification of a Case Bearing Moth Larva.  We have decided that your original written request was so nicely worded and your response was so kind that we retroactively determined to go live with a posting.

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

I found these in the bathroom at night, they don’t seem to have legs but somehow can climb vertically, it crawls along by sticking its head out , grabbing hold of something and pulling itself forward , if you blow on it it retreat inside it’s shell and then sticks its head out of the other end, or is it double headed. I have a short video of this but I will send you a high def photo.

Dear Lyn,
This Case Bearing Moth Larva is either
Phereoeca fallax or a closely related species.  See BugGuide for a comparison image.  According to BugGuide:  “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” and “larvae feed on old spider webs; may also eat woolen goods of all kinds if the opportunity arises.”  We also believe the larvae will eat shed pet hair as well as human hair and other organic substances found in the home, and we have received documentation of Case Bearing Moth Larvae feeding on pet food.

Daniel thanks for the info,and the speedy response, that is fascinating, nobody around here has ever seen these thing before.

I have these little yellowish grub type worms crawling up my walls, I had to remove the ceiling tiles to get at them. Every morning and every day I get home from work I collect anywhere from 15-30 of them and I have no clue where they are coming from. What little food I have in my house is all sealed and they’re not coming from my trash can. Usually in the morning I find them hanging by I guess a web they make off the ceiling. It’s been a week now and I can’t get rid of them. They’re just more of a nuisance now. They have little legs and a brown head. I think they are forming into these little brown moths of some sort because I seen a couple flying around.

Got a some kind of bugs in my kitchen. They navigate toward the ceiling. I collect about 15-30 every morning and when I get home from work. Don’t know what they are, where they’re coming from or how to get rid of them.

Dear Steele,
We hope you are not irritated with us for not responding yesterday.  We had a very busy day doing public service planning and organizing a ten year anniversary commemoration of Heidelberg Park and we did not answer as many letters as we do in a more typical day.  We believe these are the larvae of Indian Meal Moths, or Indian Mealworms,
Plodia interpunctella.  See BugGuide for verification.  They infest stored grain products like corn meal, oatmeal and even pet food and bird seed.  You are correct that they metamorphose into the moths you are finding.  We suggest you thoroughly search the pantry for the source of the infestation.  If they are appearing in the numbers you indicate, the infestation should not be too difficult to locate.

Thank you very much!! That is what they are!!! Now I just have to get rid of them.  Guess I have to trash what little food I have in my cabinets!! Thank you again!! And I am glad that you offer your help for people like me! I searched all over google and couldn’t find a thing to what they were.
Sincerely
-Steele

Case Bearing Moth Larva

Dear Ray,
This is such a wonderfully detailed image of a Case Bearing Moth Larva.  While they might be considered as Household Pests that could damage organic fibers like wool, they are most likely benign and feeding off shed pet hair, human hair and other organic debris like food crumbs in the home.  The case is made of silk and incorporated particulate matter.

WOW, That was a fast response, Thank you for clearing that up. we called it a flounder bug., left it alone last night as we went to bed, When we woke up she was gone..
thanks again, great service you have.
Have a great day.
Ray
