We have rats. Many! They are outside the "compound" and come out at night. Their tracks are all around the outside of the fencing. They are also under the duck house...>We have seen them at dusk under the wire floor. We have chicken coops and duck houses. I need ways to kill them. Advice would be greatly appreciated! Live traps are not an option...they are expensive, I don't want to "re-locate" them in anyway...I want them GONE! and, I think there are a BUNCH!
