If anyone is interested there is a YouTube channels dedicated to mouse traps and other rodent traps: Mousetrap Monday.

Edit: he also has a bit about rat poison somewhere where he explains how to prevent non-rodents from eating rat poison. I cannot vouch for it but it sounded smart to me (farming background).

Edit 2, here's the video: https://mousetrapmonday.com/videos/why-rat-x-is-the-only-rat...

In a couple of the cuts we can see ingredient names, but I, like Shawn in the video take the declaration with a pinch of salt.

For me I'll use traps anyway at my current "farm".
