Stop poisonning the sewers ecosystem
Making a box to put the rodenticide inside
Educate humans about the need for rats in sewers (they clean, they create natural drainages)
As the problem is due to the laxity of humans it is necessary to make them understand that rats are useful to this ecosystem and that humans must change their habits and make them understand that we can live in harmony.
