When I first started hunting NW Ontario I attempted to use corn as bait with zero success. Red Squirrels wouldnt even touch the stuff.
Then I noticed that some hunters from Wisconsin where using alfalfa as bait in the same area. I tried that and it worked as expected. IN my home state deer will hit alfalfa as well, but typically only in the winter. Put the stuff out in the fall and they wont touch it.
Like I posted earlier, baiting takes some thought to work right.
