This is something many would rather ignore, but when you pack away your heavier wool suits and coats for winter, there is a good chance they could get eaten by moths if you don’t do something to prevent it. This seriously diminishes the value and is very difficult to restore.
One reason people do not want to even think about this task is the moth ball smell, but the truth is, moth balls aren’t necessary to keep moths away. You can store your clothes with cloves, which is a moth repellant, and have pleasant smelling clothes when you unpack them in the fall. You can buy cloves at most any store, and put them in a mesh bag or empty a tea bag and put it in there(or several spread among the clothes if you have a lot to store).
There is a terrific article on maintaining your wardrobe at this Art of Manliness link, one of my favorite websites!
