According to the Minchas Elazar, the Baal Shem Tov evicted the Sheidim from where humans live. Does that mean that they are still located in the wilderness areas and one must be "choshesh" for them there?
According to a very good, learned Chabad rabbi and a very good, learned Yeshivish rabbi who went to the Mir Yeshiva and learned from R. Noach Weinberg and R. Moshe Feinstein, the Baal Shem Tov evicted most of the shedim. They are not allowed to be near people.
But, just to be on the safe side, it's good not to go to an abandoned house or building, other than getting hurt by something falling, "wild animals" seem to inhabit such places. Also, where a tragedy happened in a home, you should sell the house or not buy the house if you find out there was a murder, suicide, etc. Even the goyim are careful against such things.
