dear mr. bugman
for many years now i have had these white small 1cm size chrysalis hanging from my ceiling and now i have uncovered them under the beds, along with oodles of small black piles…? they seem to like leather and clothing under the beds but i have never seen them produce anything like a moth or worm? can you advise
I do not think them any harm but wonder if they contribute to my asthma and allergies, dust mites etc

Case Bearing Moth Larvae

Dear Debbie,
These are Case Bearing Moth Larvae, a common creature found in homes worldwide.  While we do not believe they contribute directly to your asthma, they often feed on organic debris like shed hair from pets as well as people.  The accumulation of debris under beds and various other places might be contributing to your asthma, and the Case Bearing Moth Larvae are just symptoms of a pre-existing dust problem in your home.

Really interesting! Do you mean the moth lives inside the casing and moves about in it? As I have never seen any moths in the house or anything emerge from them? Are they living and moving about in the white case
Kind regards
Debbie Millington

Hi again Debbie,
The case is spun by the larva and occasionally incorporates sand and debris in its construction.  The larva lives in the case.  Eventually the larva will pupate in the case.  Perhaps they have never had a chance to emerge as tiny adult moths because you have discovered them and cleaned them away.  It is possible that Case Bearing Moth Larvae my eat organic fibers and protein, hence being considered Household Pests.

Hi,
I am trying ti ID these characters.
Don’t know if their related or not.
Finding the grub/larvae mostly on ceiling, and on walls. Has a ”silk” thread. Also, Have seen a fly? with silver/grey/tan on wings both appeared around same time.See third photo. About 7mm-1cm in length. When crushed(sorry)insides leave a very pronounced black stain.
May have come in with some birdseed, though not sure.These insects appear daily, even after thorough removal of all visible specimens. Could really use your help. Thanks

Caterpillar of the Indian Meal Moth

Hi Eric,
The moth in your photo is an Indian Meal Moth,
Plodia interpunctella, a species that infests stored grain products as well as bird seed.  The caterpillar also looks very much like the Indian Meal Moth Caterpillar images posted to BugGuide, and since the appearance of both the moth and caterpillar happened at the same time, it is a fair assumption that they are related.  You might want to remove the bird seed and we would also recommend cleaning out the pantry to make sure they haven’t infested the oatmeal, nuts or cornmeal you might have stored on the shelf. 

Indian Meal Moth

Hi Friends,
Think I have found answer to my dilemma:
Indian Meal Moths!!! But if you have the time please confirm this.
Thanks again for your time, Eric

Hi again Eric,
We did not notice that you had already self identified your Indian Meal Moths prior to our creating this post.

Hello,
Let me first say thank you for your fast reply. I did manage to ferret
out the ID of these. But one thing is for sure I have found another interesting site to visit and
find it to be not only a valuable resource, but rather entertaining.
Best Regards, and Thank You again,
Eric

Hi bugman,
I found these bugs underneath our bed while we were cleaning the house. They look like worms and they move by extending something from one end of their body and pulling themselves forward. Do you know what they are? My wife is freaking about this discovery.

Case Bearing Moth Larva

Dear Aaron,
This is a Case Bearing Moth Larva in the subfamily Tineinae, and we believe it is a Casemaking Clothes Moth,
Tinea pellionella.  According to BugGuide, they:  “Feed on wool, feathers, fur, hair, upholstered furniture, leather, fish meals, milk powders, lint, dust or paper. Judging by the quantity of pet hair in your photo, they have an ample food supply.  Vacuuming under the bed more regularly to control pet hair should reduce the number of Case Bearing Moth Larvae you find in your home.

Thank you for the quick response Daniel, you’re awesome! 🙂 I’ll be making a donation to your website!
