So, I have rats in my backyard, apparently. I take the chicken food in each night and pick up the waterer. I've cleared the yard of most good rat hiding places that I can. I put a couple of traps in the shed, but no luck with those yet. The stupid creatures won't go away and have started tunneling under the edge of my run. They can't get into the coop, but they do get into the run. I rent and can't do anything permanent like dig up the ground and bury hardware cloth, but I do intend to place pavers around the outside edge of the run this weekend to try to stop the tunneling under. I won't use poison because I have dogs and so do my neighbors and I don't want to poison wildlife. I plan to put out more traps. I want these rats gone! Has anyone had any success in using bobcat, coyote or fox urine that you can buy to convince rats to go away?
