My house is small but I think I would have to empty a room, cover the walls and floors with plastic and put them in there. I don't think I could handle that. I feel so sorry for you, it is heartbreaking. You opened your house to them and it looks like they are trying to ruin it!! I feel bad for them too since we know they are trying to tell you something and they have no other way to do it.. It is a sad siutation for you..

Could you maybe cage them and let them out one at a time when you can watch their every move? You have to be wore OUT!
