One must realize the best approach is to remove the infestation in the storage area by inspecting all specimens, eradication of any active infestations, cleaning away any evidence of insects and establishing a zero point at which you know there are no insects and then have an IPM program to maintain this by continued inspection in storage and of any incoming specimens and materials, i.e. beetle colonies used for cleaning skeletal specimens also harbor other insects such as varied carpet beetle, these can come in with cleaned materials and move off to other collection. The IPM program is initially labor intensive but when established easy to maintain.
