I don’t think baiting is a major cause of CWD spreading. Deer are always licking each other, eating under the same acorn or apple tree or spilled grain from farmers. Stopping baiting isn’t going to stop anything in my opinion. Deer aren’t solitary animals and have constant contact with one another.
I watch and have read Dr Woods alot he has a lot of knowledge on whitetail , probably has forgot more then most know.. His property basically a 600ac (not fenced) test facility known as the proving grounds is now considered in a CWD area (because they found CWD in one deer over a county away) and he can no longer bait, feed or put out minerals. The insight I have gained from him over the years about Whitetail management is priceless. Also if you ever get the chance to attend one of his field events at the proving grounds do it!Grant Woods has a theory that baiting may actually slow the spread of cwd, because deer that are baited/fed travel less than deer that move around browsing.
They start talking about cwd a little past halfway through this podcast.
