Whatever, it's shit that wards them off. I'm not the one who set it up. Not sure who did. Might want to talk to the Winchesters about taht.
Anyway, for the rest. [insert picture here] For salt lines, just the doors and windows should do you. Every door and window, mind. Yes, Loki as in the Norse god. And you're more than welcome, love.
