Any fabric can get mites or bugs in it, but especially organic fibers like cotton, linen, flax and wool. I did a summer internship at a historical museum YEARS ago and learned that to be safe, you should put fabrics or clothing that has been stored very long without being in an airtight container, into a trash bag with a "no bugs, M'lady" strip. And then clean/wash it. I don't think that these bug strips are still available for whatever reason. But I learned from a nurse that had a daughter that routinely did missionary work in India, that any time she came home, all clothing went either into a very hot dryer or into a black plastic bag that was left in the sun--then cleaned/washed in as hot of water as you think it can stand. Good luck!
