AHA! So jdsf was ribbin' me? Shame. It sounded such a neat idea.
Even so, I think I'm beginning to detect a pattern here. Foodstuffs with pungent or volatile constituents (orange peel, mint, cinnamon, Tabasco, etc) can disrupt ant signalling agents. So I hafta wonder, could onion or garlic work on the same premise? Might try that as well just out of curiosity, & possibly add yet another chemical weapon to my list of options.
