What about Bentonite clay? I read that's supposed to attract them and pull them out when it passes through the body. Maybe I'll try it. I'm just sort of confused about all this. I was trying to starve them off somehow by flooding my bloodstream with all these herbs & tonics and nothing they liked, like a fast. But that makes sense too, luring them to the stomach then posioning them. Its just hard to know if the poison will take effect before they have eaten and moved on.
