I can tell you what I have read (and don't remember where) to put in plastic bag and put in the freezer--for at least 48 hrs. It is supposed to kill the moths and larvae. Before I learned this, a friend asked me to alter a mouton jacket that she had bought at a yard sale. I had it in a bag, lying on my washer for several days. When I opened it to proceed, little worms fell out. The moth eggs had hatched. She told me to toss the coat. Then I learned about the freezer. EHOW.com might have some info re what to do. Gee, I never thought about moths and wool batting--think I will stay with cotton and poly--can't stand creepy crawlies!
