Give specific details on the location e.g. is it in the attic, under roof tiles, inside the building, in a tree hole, underneath bark of a tree:

They seem to live in a big old maple tree between Svartviksslingan 25 in Minneberg in Stockholm, Sweden and Ulvsundasjön (Mälaren) which is right next to the building.
