Get a black candle, a bowl of salt water (sea salt works best), a smudge stick, and a length of hemp rope for each window or door in your house. Light the candle and focus on banishing evil influences.

Each in turn, beginning with the smudge stick, go around the house and mark each entrance (windows, doors, milk door if you have one, etc.); wave the smudge stick and candle in front of it, and mark the salt water across the bottom ledge of it (or threshold). Say something like:

May greeted friends be welcome here.
People unknown should have fear.
Those who without welcome cross this door
Shall writhe in pain forevermore.

Then, take one length of rope and tie five knots in it to represent a person’s limbs and head. Place it across the window ledge (or door threshold). Repeat for each entrance. If someone breaks in, one or more of the knots on the rope will be disturbed, and the person will be bound in pain until the knots are untied. If you do not wish to untie the knots, deeply bury the rope in a secluded area. The rope will rot without becoming untied, binding the person forever. This is why it needs to be a hemp rope, not a plastic one.
