I bought a starter kit it had a cd , couple colony traps ,wire, stakes attractant ,a couple foot holds . pliers and two 110 body traps for just under $100. Take a walk around your pond and see if you can find which tunnels they are using. Set up the body traps in those tunnels and stake it down. Check out what they have for videos to use the body traps. They can be a bit daunting to set but it will instantly kill the animal if caught in it and with it being in the tunnel there is less chance of your dog getting into it.Well worth the money in my opinion.
