I have had deer shy away from them from time to time ,,, BUT I get more pics of more big bucks in mock scrapes than any other way. But I do things a little different than most . First I save tarsal glands, the smellyer? the better from harvested bucks, preferably from a different herd, ie another county or state. I cut them into at least quarters and freeze them. hang one on a limb above your scrape. hang a scent dripper , use a string and pull it up at least 8-10 feet so they cant reach it, then bury a bottle of scent an inch or so under the dirt with the top off. Do all this while remaining as scent free as possible. Do itin the next week or ten days and see what you get. I have some amazing footage by doing this.
