Thankfully, I have not been seeing any moths flying around the house or any holes in my sweaters, but this article in the Washington Post caught my eye, so thought I should share in case anyone's had to face this distressing development.
I've heard from an expert at the Textile Museum that placing clean garments in plastic bags for short periods of time can really help in avoiding infestations and preserving items. The WP article also suggests hot storage or running a garment through the clothes dryer, though that sounds a little scary for a wool garment that you want to keep the same size!
That's why I keep my yarn hanks and balls in plastic containers, for both organizational and cleanliness purposes. I just heard recently also that you should not wind a hank into a ball until right before you're planning on using it -- the pressure of the outside of the ball on the core can adversely affect the consistency of the yarn. I'm not sure I've ever noticed anything like that, but I found it to be an interesting tip...
