i had ants in my house last year...i didn't like the fact that i used Grant's ant stakes (which worked), so i put a whole mess of brown sugar outside where they were coming into my place. needless to say, they stopped coming in, and festered around the sugar.
highly non-nutritious, i'm sure. :( but not lethal, either...and it was fascinating to see them work. rather like goldfish watching.
i agree, however. your space is your space (vbm re: food source); if they're violating it, tell them to go, and if they don't then you have the right to clear it.
