If you don't want to use bait or traps, as a pest controller I would look at why they are there and remove it or exclude them from accessing it. ie food source (compost, bird seed), free standing water source (garden pond) shelter ( overgrown garden)If you remove these from the area then they cannot survive and will move on. It sounds like there is quite a few rats? Not just 1 or 2. I would recommend a baiting program myself preferably placed directly into the burrows and them cover the bait over
