We only buy the more expensive foods that the birds love so they don't discard the wheat and barley that make up much of the cheaper mixes ... these attract pigeons and rats. The more expensive ones work out cheaper in the long run.
Big favourites here are Sunflower Hearts and a Robin and Softbill no mess mix ... none of this is discarded
I would also go to the nearest hardware store B&Q or similar and buy some rat bait and a bait box so that you can get rid of the rats (and there will definitely be more than one) safely and without endangering children, pets or other wildlife.
