Anyone ever used them on hogs?

I've used the doe in heat ones a few times on deer, had mixed results, had to be in the rut and seemed to either bring all the little bucks in running or scare everything away. I tried the food attractant ones and never had any deer come in to them.

Just wondering if anyone tried the food based ones on hogs?

I don't see much on using any scents for hogs. Seems like as much as they rely on their nose we should. But then I wonder if you used it repeatedly on the same property would you just train the hogs that smell means death so lets get out of here?
