I wouldnt wait. I think you could literally use a mock scrape year round.Mid summer is when I get mine going. This time of year a good tactic I use is to take over a scrape if there is one in the area your hunting. I wont promote a scent because I think most urin will work. Im seeing scrapes all over. I like to use them on the outside borders of a bucks area. An inside corner with a fence line seems to be a great spot. Just make sure you got a licking branch overhead and scent it up too.
