The first, second and third photos are of *Porcellio spinicornis* - a species native to Europe which has colonised North America. It does have a habit of coming indoors, even in rather dry conditions, but is unlikely to do much damage to collections. If you are getting large numbers, it would be worth investigating whether you have a damp problem. The smaller, greyer specimen looks like it could be a young *Oniscus asellus*, but I'm not familiar enough with the North American woodlouse fauna to be able to exclude other species. Tony
