If I may suggest; I have posted this response to another thread though.
One mix that has worked for me is;
Go to a food store and buy Kosher Salt and garlic powder (the garlic powder was suggested by another SOM member, as I had already posted this response).
Get or buy an empty spray bottle (at Dollar General or Wal-Mart).
Place into the empty bottle 1 or 2 heaping tablespoons of the Kosher Salt and 1 or 2 heaping tablespoons of the Garlic powder.
Go to a Roman Catholic Church and ask where the Holy Water is. And just fill up the spray bottle. Many people do this to take home for various purposes for their personal Christian Altars.
Shake and mix.
Then go to an herbal shop or Occult shop and buy a sage bunch that is tied (use to smoke your home to cleanse your property).
Then make up your own banishing prayer or use the one from the Bible; Psalm 23:4 "Yea though I walk through the valley of the shadow of death, I will fear no evil: for (Avini Adonai-My Dearest God is) with me..," Through Yeshua Kristos the Son Of God who amended the Sins Of the World in my behalf, it is my birth-right to BANISH YOU! YOU ARE NOT WELCOME IN MY HOUSE! Leave my house now, I command you by the mercy of Avini Adonai! Deo Duce y Yeshua Kristos, semper fidelis, perdurabo(God is my Leader and Jesus Christ, I am always faithful that I will prevail)!
Joshua 24:15 "As for me and my House, we will serve the Lord!
Anyway, these are only suggestions, whatever but, state your prayer with much commanding emotion. As if someone has made you very mad inside your home (or your property), and you are TELLING them to leave.
Now, with your ammunition and your prayer at the ready, light your sage and hold it in one hand until it just smokes (it can spark, watch out), with your other hand, hold your spray mix.
You are a prepared warrior now. Go forth and banish your enemy!
Spray everywhere, smoke everywhere while stating your prayer in a mad commanding way! You're pissed and you're not gonna take their shit lying down. You will not go quietly into the night.
Blessed be a paradise for you now, here, on this good earth!
