I'm having the same problems myself.I have mostly rats and have been trying forever to get rid of everyone of them,but I don't think I'll ever get rid of all of them.i have used poisons in the past but it just cost so much to have to keep putting some much out will little results.I finally bought a repeating trap that works very well.Yiu will have to keep all feed cleaned up,I've even quit keeping my feeders full to cut down on what they could get to.I also have been doing major clean-ups around sheds ,barns and my pens.We have 40 acres here and our land just goes off into the woods and its tough keeping weeds and brush cleared.But it is helping and I plan to stay on top of it till at least the rats figure out the survial rate here is not good.Best of luck to you.
