The reason I bought both, was that I don't know how to choose between them. Do you?



While the price difference was huge, I don't buy by price, where, when choosing between products, what matters is how well the product works.



Googling, most articles are simply about how they work, now how _well_ they work in the home for the typical use in closed small spaces:

There is a lot of information about EPA rules for using the poisons:

But I have little empirical experience with either type of rat poison. o Do you?



Given the price difference is phenomenal... o *How do you choose between these two available types?*


What matters is what the rats/mice choose to eat.

The only way to find that out is to try some and see what gets eaten and produces no more signs of mice/rats.
