Territorial Demons?

Are demons attached to certain locations? The question is not a silly one. C.Peter Wagner researched the subject at length and concluded that some evil spirits are apparently tied to certain locations, as evidenced by missionaries' encounters with them. Wagner's views have not been accepted by everyone, but he made a good case for them in his 1991 book "Engaging the Enemy: How to Fight and Defeat Territorial Spirits."

I have also read other deliverance books defining certain spirits that pull power from objects (tokens, voodoo mask, ect).

In the book of Acts it mentions the very touch of the apostles, demons shrieked and many were healed.
