What's That Bug? does not endorse extermination

Can’t quite figure this one out…
Hello Mr. Bugman!
I love your site and you’ve done a great job cataloging and explaining to people what bugs they have been lucky enough to photograph or see. I searched and couldn’t find out about my bug. I suspect that it’s a bagworm but i’m not sure. I live in St. Petersburg, Florida in an older wood framed house. We have lived her for 2.5 years and i’ve never seen this insect until the past few weeks. I’ve seen probably a 8 or so. They are usually >crawling up a wall – inching their way up pulling this sandy very flat sack like thing behind them. In the photos I’ve attached, I placed in on my bathroom sink to get a better shot. He has some lint attached to >him from the baseboard. I didn’t measure this one but another one I just found is about 1/8″ and he was smaller than this one. I would appreciate any feedback if possible.
Thanks so much!

Hi Mo Eppley,
You have Case-Bearing Moth larvae. We have additional information on our clothesmoth page. The small larvae carry a noticeable case made of fine sand and debris. The case, which is about a quarter to half an inch long, is flattened on top and bottom, expanded at its center and tapered at both ends. They are often found on walls (both outside and inside) of houses and other structures. Larvae are said to feed primarily on insect remains, fur, flannel, and hair: they do not seem to be a clothes pest. We have gotten several letters from Florida regarding Case Bearing Moths.
