I had wondered about this.
Several years ago "Carolina Wool Eating Moths" showed up here, a new species for our region, apparently. We had a bit of a problem with them in this house, and they went after a rarely worn pair of wool trousers, which I rarely wear, and did some very minor damage to them. And they went after a South American wool sweater and did it some damage. They didn't go after any dry cleaned and stored wool items at all. The better the quality of the wool item, the less it seemed to interest them.
They didn't bother any of my good beaver felt hats at all. The moths got into a Russian fur hat I have, but didn't bother it, they apparently were only touring it. They did bother a wool newsboy, and they ate one single tiny hole in a Stetson Australian type hat.
After that, we cleaned everything out extensively, and both cedar strips to discourage them. They still show up once a year, but in very minor numbers and they don't bother anything that I can keep track of. It is aggravating, however.
I'm encouraged by the reports of cedar working.
