I hate the war metaphor too. You'll never get rid of rats entirely. Controlling rat populations in cities is really about food sources. The number of rats is limited by the amount of continuous non seasonal food sources available. In this case it seems like the city needs better garbage cans.

Proper maintenance to keep rats out of housing helps with the nuisance aspect. Because rats are destructive.

One wonders, if you got rid of rats, what would take their place? No idea, might be worse. I think the current brown rats aren't actually a disease vector[1]. I've read speculation that the decline of the plague was due to brown rats displacing black rats in cities. Maybe brown rats are doing us a favor.

[1] Rat lung worm in Hawaii though is a zoonotic nuisance. Also a friend got rat lice once.

Many cities don't have a significant rat problem and they don't seem to have anything worse as a consequence.

It's a bit disturbing that it's the go to metaphor for promoting policies.

This is great.
