I tend to agree with Scott. I live in farm (cattle) country and we have a fly problem. Even the stores take steps to alleviate them. Consequently, I use bug spray a lot. I have never found a problem with my stuff stored in the house. I have had problems with things brought in from other sources. I have only several pieces of quillwork and I tend to display my stuff. Guns, horns, quillwork, baskets,etc. I think that keeping the pests down is a very important step to preserving your collection while enjoying it.
