Whitetail bucks are very territorial. Scraping activity has more to do with letting other bucks know he is in the area than it does with attracting does, think of it as very similar to how male dogs mark areas belonging to them. I’m sure that you have seen how the pooch lifts his leg on the corners of buildings, bushes, car tires, and fire hydrants, and then how the next dog to pass by will leave his own little remembrance in the same locations. It’s as if whoever pees last wins.
Bucks will check out scrapes to see if there are other deer in the area. If you want to hunt over scrape, just be sure it’s in an area where the buck feels comfortable during daylight hours.
