We are a new state archaeological collections management facility - opened in 2008

All incoming collections are placed in an isolation room.  Sticky bait traps, placed at strategic locations, are used to detect and control insects.  Collections are monitored for six weeks before placement within permanent storage.

We are currently exploring two options for more effective, and time efficient, methods of insect control for incoming collections:
1.  Anoxic chamber [fumigation (CO2) chamber] often called "the bubble."
2.  Freezing [use of a specialized freezer]

We understand there are pros and cons to both options.   

Any comments regarding the use of the anoxic chamber and/or freezing for insect control would be greatly appreciated.

Thanks so much.
