For the most part,I stop when the snow leaves in late April,and start back up after deer season in Nov. I don't worry about pups,as I pretty much stay in an area that we manage for deer and try to remove as many as possible.
I have been trying this spring with a Phantom caller and a fawn decoy,tough sledding so far,having brought in two bear and a couple fox,but we cleaned 'em out pretty good over the winter.
