I checked it out an it is a "household casebearer" - a form of clothes moth that needs high humidity to produce.

That is the link of where I found info if interested in how to get rid of them.

I have been searching forever to find out what this insect is!  They are all over the wall in my garage and I also see one or two in the bathroom.  I am in Australia so they are not just found in the US.  I had to find out what they were 'made' of so I cut one open to find little spikes of fibre, so maybe it is some kind of moth?  Thank you

This is interesting.  I live in Hong Kong (where its hot and very humid 9 months of the year) and I have exactly the same bugs in my house.  Like you, I came online to see what these bugs are - I agree that they do not seem harmful - they are like nothing I have ever seen - I just started noticing them 4 or 5 weeks ago.  At first, I thought they were paint chips or garbage tracked in by the cat.

I am quite sure it is a Plaster Bag Worm.

I have them but they are harmless as a rule.

They mainly feed on spider webs and other natural fibers.

I found the same kind of household casebearer (which is also known as plaster bagworm) in my bedroom. Can anyone advise how to get rid of them once and for all?

Thank you.

I live in lake Mary, fl, and have hundreds of them. There are hiding under sidings around the house.

I have also seen these in my house.  I live in SW Florida.  It blends in with white walls and hangs from my ceiling as well. My puppy pooped in the house one day and when I came home from work there were like 10 of these insects on the poop.  They were all different sizes from the size of a piece of rice to the size of a small sized white pumpkin seed.  They are strange.

We have them too but in our living room did you ever find out what they are?

I currently live in San Antonio, TX and have expertise in identifying insects, many types of spiders, and other arthropod critters that infest lawns, ornamentals, structures, trees, pets and livestock. Mites are not a strong point of mine. I'm not a licensed doctor, so I cannot provide medical diagnosis of conditions possibly related to insects or other arthropods. If you've got an interesting photo for me to see, attach it to your question, or let me know and I'll give you my email so the picture will get to me. If you have hosted an insect photo on a website, please include the link so I can go look at it and provide a faster ID for you. You may also join my group page on Facebook and post your picture at
