Just with regards to possible sources of infestation, are there any rodent baits in ceiling voids or to offices, etc.? We have also had a huge issue with Stegobium and Lasioderma in starch-based packing noodles. The noodles have been used to replace inorganic styrofoam packaging, but it is very attractive to beetles. Several infestations of collections have been traced back to this style of packing material.
