I've come to the conclusion you are one magnet for activity, my friend! OK, on the holy water/salt question....holy water is what Paint was referring to on the table, etc.
Salt is used to ABSORB negative energies and repel certain bad guy energies. You can use salt as a barrier, especially outside of the home. Holy water is more effective as a deterrent to demonics. You can use both...salt on the ground for barriers, Holy Water up on doorways, windows, and as Paint has mentioned, other places where you would not want them in your food, etc.
I also use St. Benedict Medals at the four corners of my house, and one in the center. I use them at the four corners of my property as well. When placing them, use prayer and reverence in doing so. Ask for the angels and saints to guard your home and keep you safe.
