Gosh! I am so sorry! I hope things turn around for you! I also battled rats at my old farm and you know what, they were winning! No matter what I did they won! I did everything I could find to try and get rid of them and nothing worked. It became this personal obsession with me! LOL I would gear up, grab my pitchfork & peppermint oil spray and go rat hunting! They went as far as to chew through concrete! Thank god I have a new place now!
