Have crosses in your home. Demons don't like Christian religious artifacts.

Start going to church regularly. Gabriel Amorth, chief exorcist in Rome, found this will help keep demons away.

Get baptized.

Live a good life, according to the Bible.

A life of sin, will draw the demons to your home.

Play Christian worship music, 24-7.

Each day, regularly, pray, in the name of Jesus, for the demons to be bound, and to be removed from you, and your home.

Get the book, an excocist tells his story, written by a real exorcist. Say the prayers at the end of the book, in each room.

Remove any objects, that can draw demonic entities to your home. Occult / metaphsycial books, musics, movies.

Stay away from shows / movies, with graphic violence, lust, nudity, cursing. You knowingly watching this, are giving approval of this. By this act of will and approval, this now gives the demonic an invitation into your life and home. The same, if you consciously and repeatedly sin. Your angels can only protect you so much. But, if you willingly sin, you then give invitation to the demons, and the angels won't be able to help you in these cases, since it's your choice to be exposed to evil. The angels, can't interfere with your will.

Be careful, of bringing anything home, that can draw demons in. A girl had brought in a CD, with a demonic entity on the cover. In the spiritual realm, it was seen, that this demon followed the girl, into her home.

A major deception, is not black magic arts. But where most will fall, is doing white magic, or reading 'positive' new age books. Be highly cautious.
