Satan and his demons have no appointed place on earth. He entered through Adam who sinned in Eden, (Romans 5:12).

The time Satan rebelled against God, he had nowhere to go. He became a vagabond. No wonder he said he was going to and fro in the earth, and walking up and down in it when God asked him where he was coming from, (Job 2:2).

Evil spirits dwell in man, though they're not wanted. At Gadarenes where Jesus cast them out of two men, they requested, and were permitted to enter into a herd of swine, (Matthew 8:32). But, the pigs felt uncomfortable and preferred to perish in a river rather than have the demons live inside them.
