I would make a scene of moving some "nice stuff" intro the house (empty boxes that say 60" tV, Stereo, high end electronics etc) leave the boxes where they can be seen from a window and hire some "adult" that is responsible for one week (to keep expenses reasonable). Chances are that the thieves are watching the house and the guy you hired won't have to remain a week. But he'd have to be armed because they could be meth heads or worse...or simply teenagers looking for money pay for their next drug buy. Just an idea, I like to fake people out and keep them guessing.
as i alluded to earlier that's nearing premeditated murder if you were to shoot and kill someone stealing from you, no hunting over bait. my friend Jack was really sweating being charged with murder
