Get a handful of iron stakes, like railroad spikes or something similar, and engrave messages on them. Make the messages something to the effect of "this is my turf and nasty things will happen if you do not respect my turf," though you should capture this in words, runes, or sigils of your own design. Drive these into the earth along the boundaries of your turf....if your house
has been attacked with stones, use one of the stones as your mallet.
