I have a very active scrape line on one property I hunt, that has been used for the 9 years I have hunted it. It was well established the first year I explored the property, and those same scrapes get worked year after year.
I have added a couple more to it, and the deer have instantly taken to them, working these scrapes as well. It's a great little hunting spot, and is a sheltered, tucked away area that bucks feel comfortable in during daylight hours.
As nice as scrapes on big clearings and field edges are, they often don't get near as much daytime activity, and scrapes tucked deep into woods, along trails, etc, seem to get far more daylight action.
I use scent on my scrapes, and even add it to the real scrapes the deer make, making those bucks think that other deer are around, and hopefully encouraging them to keep checking in, and hopefully doing so when I'm in the stand! I use scrape starter, then set a scrape dripper above scrapes.
It is an easy way to increase your odds, and well worth trying out!
