See SenesTech, birth control for rats which eliminates the most significant aspect of infestations: the population rebound (and corresponding evolutionary selection for traits which avoid poisoning).
Another effective alternative is to stuff dry ice into rat holes when they are found. The CO2 kills them in their sleep, is odorless, leaves no toxic residuals, and results in underground carcasses.
