Chics........
Since you asked, you may find these Q&A's helpful. This from an outfit that sells both, plus an entire spectrum of such professional exterminator grade products......

Keep in mind, in answer to all these questions, the reference is to use of this product in it's powder form......not mixed with coke, water, etc. Do that and the equation changes and the product gets lethal in a hurry. Then you do find stuff.....rats, coons, dogs, etc. dead with their face still in the soup.
And then.......

In nearly all cases, the only recommended way to present these baits to rats is from within tamper proof bait boxes. In the case of the blocks, they are pinned within.....so rats cannot remove them. And also read what they say about secondary poisoning to pets, etc. How many rats a dog would have to eat......if they eat them at all.
Bottom line is one method is banned in some states and not approved of in any for use to kill animals, including rats.......the other is sold specifically for use on rats and such.
BTW, I'm not trying to change your mind on this. But I would encourage others who are still on the fence and thinking about it to do their research, consider the weight of evidence and then......and only then........decide which route they want to go.
