I lived in New York State the first 38 years of my life and the last 18 here in AZ. I starched things in NY that I have yet to use and I don't have bugs in my fabric. Yes, I have re-sorted/boxed all of my fabrics several times over the years. I am also lucky enough to have wool that has not been attacked by the moths and are hole free. I guess I am one of the lucky ones..... I have read that it is the humid air that aids in the animals liking the starch. It just depends on what each of us likes to do and our experience. Just like what store we buy our fabric from and if we like hand or machine stitching.....
