hey brother,
What me and my buddies have found to have the most success, was to go bush poppin in his golf cart at wee hours in the morning, or to use steak or animal guts, leave them in your yard for a few days, let some of them eat away at it, and put more out, the bigger ones will come, seeing as though the pups will come and get it a few nights in a row. The wiser ones should come out and take some themselves.
hope this helps.
Happy hunting.
