Whatever you put out, put it in a bait station..........please. Rodent bait stations are on the shelf right beside the buckets of poison bait at the farm/suburban supply store. They cost less than $10 each and are very good at keeping non target species away from the bait.
There are lots of second generation rodenticides on the market, diphacinone, brodifacoum. Lots of trade names, Tomcat, Just one bite. They are all very effective, and are all anticoagulants.
So unless you want the neighbors cats and dogs, or the local bird population bleeding out of their ears, eyes, and rectum, keep the bait in a good bait station.
