I have a big chest freezer so I put fabric I ordered from online or from thrift stores in a plastic ziplock and freeze them for several days or until I remember about them. It may do some good. I do this with rice, meal and flour too. I do not need weevils getting a foothold. Also bedbugs can get in alarm clocks, furniture, shoes, eyeglasses, anything that is around where they are. I am very Leary about motel rooms. Even the extra nice ones get bedbugs.
