Obligatory warning against bait poisoning small animals who then become fed on by other larger wildlife including foxes and owls. Which then become poisoned and can die in turn. So if you choose to use poison especially those that coagulate the blood to kill, you may be killing other wildlife.
I rescued a dog a few years ago that was living by the Rio grande (river on one side, ditches farms on the never) who had been rat poisoned. She likely was eating mice and other small animals that had been poisoned.

She was in a really bad place when I found her.
Biomagnification is a real issue, yeah.
