Probably a coon. Do what your doing but keep your traps outside the barn. No that you closed everything up you want to get him when he is outside. I doubt he is sleeping in your barn... you would have noticed this earlier plus you would have seen the destruction they make.
Canned cat food is a good suggestion and I always use tunna in a can. (in my opinion the stuff smells the same)
Good luck... they are relentless creatures.... but you are going to need something bigger than a squirl trap. Your local TSC or if you have Harbor Freights by you... they both carry the have a heart trap... they are more like a "have a death wish" trap to me.
