What works best for mouse/rat/gopher poison & in what concentration?

I already use rat traps on the floor in out-of-the-way places, but,
in the basement drawers and shelves, I don't want a trap which might
snap on an unsuspecting human (nor would it fit in some spaces).

So I just want to drop a few pieces of poison in the drawers and
on the shelves that have droppings in them.

Today, I saw the following at the hardware store in California:

Brodifacoum 0.005%

Bromadiolone 0.005%

Bromethalin 0.01%

I couldn't find any chlorophacinone, or diphacinone; so I ended up
buying the cheapest they had, which was the Bromadiolone:

But, for the next time, I wish to ask:

Q: What mouse/rat poison do you use for basement drawers & shelves
(and in what concentration)?
