kill a deer it wont go back ant tell its freinds to stay the fuck away but shoot it a few times with a paintball gun or ruber bulets and your problem should go away (probably limping)

alternatively if you are the nerdy tipe build a few trip wires near the site wired to dynamite or pipe bombs. extream i no but if it comes down to it and like you say, if its war....

(dont actualy put up explosives as they are very dangerous)

i just use pee.
