As it is St Michael's Day, Michaelmas, here is a prayer which appears in An Alternative Almanack of Unlikely Saints by Chris Sempers and Elizabeth St. George. It is used both for personal protection against foes and all evil, and to banish negative energies and entities from your home.

Michael, Archangel, 

defend us in the day of battle and be our safeguard 

against the time of darkness. 

May the Shrouded One dispel all evil, 

Michael, thou Prince of the Heavenly Host, 

by that ultimate light, thou shalt thrust all evil from us and protect us 

from those dreadful things that wander through the world for the ruin of souls.

Go forth from this place, O Evil, 

in the name of the One who has created all things. 

May all the power of our enemy, all the dark host, every evil onslaught, 

every phantasm depart from here, now and forevermore. 

Leave us, O Darkness and all evil. Go hence in the name of Deity.

So Mote it be!
