I have a rat problem too. I dont feed birds much as I would like. I keep the area round my home clear of all weeds and plants etc. make sure it is open. No sheds, no place for rats to hide.
The problem? My next door neighbours on both sides have chickens. The food attracts the rats, the rats have moved into my hedges because they are safer but still within food source range.
Once you see a rat, its too late, there is already a colony. All you can do is keep baiting it and hope they dont get in your house or sheds. Track them down via the run if you can.
I did have one in the house, it ventured in through a cat flap! The cat went after it but it bit him too! It got under the kitchen cupboard. My husband had to bludgeon it to death with a sledge happen on the end of a wooden baton we pushed down the back of the cabinet . Awful business.
