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

    • Same with my experience. There are approximately 20-30 case bearing moth in our bedroom. First, I thought that they’ll not cause harm in human body. Days after,me and my husband have red dots underarm and it hurts so much. Our skin got damaged after swollen with blood popped out. This insect is very dangerous especially when there is a baby in the house.

  1. I am being attacked daily by case making clothes moth. I must have hundreds in my house. I can’t feel them bite, but they have destroyed my skin. They bite in a line on my arms and face and leave a huge welt. They are definitely a pest to be worried about, as they seem to like a blood meal. I was told my diabetes attracts them to me. They are also eating my hair! Any suggestions on repellant would be greatly appreciated. I kill the larvae with Thuricide. Adults are a little harder to kill. I use Imidacloprid. (Bayer advanced-complete insect killer). Both are available at home depot.

  3. I just found one of the case moth larvea hanging on my paper towel roll when I picked it up it wasn’t afraid of me and just was picking all the way out I was so concerned to what it looked like that I opened the little pouch it was hiding in and found the little worm inside so freaking amazing what lives in this world. I’ve always thought it was some bug that left an egg sack that I simply just flicked it down the sick. Now I know what they are and will just put it outside. Thanks for the information. No need to be afraid of them. They don’t bite.

  4. In above picture, about how big is the cocoon, what does it look like up close and, if say, it were unwrapped and laid out? Like a train track maybe?

  5. That do bite humans . I just dug two of them out of my scalp. I have been suffering for two years with these monsters. They are in the walls, eating everything they have in front of them.
