While it is helpful to know which are the infested pieces, I would strongly suggest that you bag each piece separately. This is good standard procedure for any organics that come into your museum that have the potential to have an infestation. Polyethylene bags are available in a variety of sizes and thicknesses (also in rolls of varying widths) from many companies. I have always had good results from Associated Bag (http://www.associatedbag.com/). This will keep the insects from moving from one piece to another.
While it is possible to treat moth infestations with para-dichlorobenzene, the active ingredient in moth crystals (as opposed to napthalene, which is a repellent, not an insecticide, and was used in moth balls), the better option is to freeze the objects. The NPS has a Conser-o-Gram on the subject: http://www.nps.gov/museum/publications/conserveogram/03-06.pdf that you will find useful. Most museums, of course do not own the kind of freezer necessary (a home freezer doesn’t get cold enough), but you may have access to one somewhere in your community.
And, of course, it is important to know what kind of “weevils” you have 🙂
