Rats are Extremely smart. Even if that combination would work, the rat population would quickly learn to avoid that food. Controlling rats is an ongoing WAR in many Large cities. (like Chicago) Am sure problem is everywhere else, but to different degrees.
Wherever there are people, and garbage, and other source of food, rats are likely.
The one rat poison that seems to work, (I don't have any brand names to suggest)
works in such a way that causes rat to become very thirsty , and drinks water to excess, and expires. The rats do not associate the problem with the food (poison) but rather the water they ingested afterward.
There are other methods to control rats, and some seem inhumane and cruel.

I know we do not live in an IDEAL UNIVERSE.
