Thanks John! We have problems with folks taking seriously the weaknesses in our building envelope and the pest risks that come with it so this should help them understand how important that is, hopefully.

The book says that the Dwarf Shrew habitats include "alpine rubble slopes, pinyon-juniper, shortgrass prairie, sedge marsh habitats, and dry stubble fields. In South Dakota, dwarf shrews have been found mainly in grassland" and are active year-round, feeding on "soft-bodied spiders, insects, and carrion." Based on this information, your strategy should probably be sealing off all cracks, crevices, and other penetrations of the building perimeter so they cannot seek harborage in your building, and eliminating other pests they may be feeding on inside the building. Their risk to collections is most likely from searching for nesting material and being attractants to other pests if they die (as you probably know, shrews have a very high metabolism rate and starve rather quickly if they cannot find food).

We have had problems with shrews in the past and found a new one in a trap today. We have pygmy shrews here in South Dakota and I think this looks like those. Can anyone confirm? And can anyone point me in a direction to find more out about these shrews and the risks they pose to collections? Thanks!
