If you are religious, then you will know that the story of Jesus casting devils and whatnot out of people and places is someting to think about.
When I served a mission in Mexico, I ran into ALOT of this, and me and the guy that was my travelling companion were frequently called on to cast out the bad spirits. I have done this here in NC as well for my boss at work.
The proper phrasing is to do it in the name of Jesus Christ. Tell them to leave in His name, and it will work. There is nothing to fear, because those evil spirits cannot really harm you. They do not have tangible bodies, and can only do you ill will if you are weak of mind. You are not a weak minded individual, and are stronger than they are, but they do not want you to believe that.
So...prove it to them.. They hate it when they are ignored or laughed at.
