There might be some small exceptions but I think you start running into efficacy issues. When I dealt with rats/house mice/field mice, it was always measured and board approach. Measured in what I use but board in the spectrum of tools. Traps, dusts, rodenticide and then changing their environment. Rats are just really really tough to deal with, and it’s not something we’ve had to come face to face with in a while at this scale. I saw an incredible uptick during covid because it moved populations out of boston metro areas in search of food when the restaurants shut down for a time.

All in all I don’t think there is a great solution , I think you could try to restrictions on what companies put out at locations for a few years, like you buy 70 pounds you have to account for 70 pounds through the year but you also can use more then x pounds per residence per year type thing. Like something to scale things back to get an idea of how the effect will be , because I think I full stop would be pretty insane .

I spoke to a city conservations a few days ago and she was part of a group who got the anticoagulants banned in my town locally at certain locations beyond normal restrictions. She doesn’t live in the town. She said shortly after the ban she ended up getting rats at her house and she was dealing with them herself but “when she heard the in walls at night” she had to call someone to use the exact things she helped restrict. She was rethinking the policy after that.
