Ok. So I have this rodent running around my chicken pen and underneath my dishwasher and cabinets in the house. I am not sure what it is but the butt end of it was about 1 1/2" wide!!! It's brown so I am not sure if it's a rat or a vole. Any suggestions on how to get rid of this annoying thing? I do have a have a heart trap set...but it's too smart for that.
