Thanks so much to you and Nancie for all of your help talking us through this, by the way! Relative to the size of the building, which is vast - big enough to house several trains - the infestation is not particularly widespread. It's confined to one end of the building, seemingly. Within that end, both beams and objects are infested. We're comfortable at this point only treating structural elements of the building that show signs of infestation. Our winter here has not been the long, deep freeze that we expected - but instead has been spring-like, so I'm a little concerned that perhaps the spread of infestation might not have been as slow as we would have hoped this winter, while we're deciding on a plan of action. A new question - there are some infested objects (both painted and non-painted). The nature and use of the building over the years had led to collections and non-collections materials being stored together. Our first thought is to move the collections materials that do not show signs of infestation to another portion of this vast building to watch for infestation, while the building structure is being treated, while non-collections materials that are infested are discarded and collections materials that are infested are treated (we're waiting on the details of this from our pest management vendor, but thus far, we believe he is going to propose some method of fumigation). We did not move to wrap any of the infested materials, since it was December in Wisconsin and quite cold when we discovered the infestation - and that is one question - should known, infested materials be wrapped? Another question - what about those collections materials that we are going to move out of the infested part of the building. Should they be wrapped, if possible, to avoid potential spread to another part of the building? This is all happening on a large scale - so it will be labor intensive and costly to wrap anything.

We have been quite successful in controlling powder post beetles by applying Bora-Care only to the infested areas as identified by holes with frass in them and trails of frass extending from the holes, areas such as the sill of the building or the base of columns where the wood has a higher moisture content and is more inviting. In Vermont, we find that such infestations travel very slowly, perhaps because they have been held in check by our cold winters. It would be prohibitively expensive to treat all or even many of the structural elements of the building as a preventive measure when there was evidence of active infestation in only limited portions of the structure.You can always apply Bora-Care in the future to additional areas if you detect a spreading infestation.

We're satisfied with all aspects of the proposed treatment (Bora-Care application) - however, the pest management company has proposed a widespread application, and we're wondering if the application of Bora Care should be confined to just the area in which exit holes can currently be seen, or should it extend beyond that?
