Say the following while in the house:
Any evil spell against this place
Or against the one who rents it
Will be scattered for apace
And returned to the one who sends it.
I now invoke the law of three
This is my will so mote it be

 

 

Make four little blue drawstring bags, each the same size.
Mix in a bowl dry angelica, Solomon's seal and balm of Gilead buds.
As you do this visualize your house protected from evil.
Divide the mix into four equal amounts and fill each bag with it.
Hang them or hide them in the four corners of your house.
