My neighbor had rats in the crawl space under his house. He was excentric to say the least. One day he had no water pressure they ate through the 2" hose from the well and it was spirting everywhere. I covered it with dirt as far as i could and the rest with window screen. Then one day his sink was leaking they ate through the P trap so i put on a metal one and blocked the hole with window screen. also noticed they ate through the bottom of his dishwasher. I think he exterminated most of them after that but who knows if there is more.
