I have seen 'worked' scrapes and licking branches in every month but june and july and the beginning of august, the hottest months, and there are probably a few being used, but I'm not in the woods much then....it is just the vast majority of activity occurs in the fall. I have never put a cam over a scrape later than December though since usually there are better spots after the rut but I would be curious what deer use the scrape in the off months. Just dominant bucks or more than that?
