Here in North London we have tons of rats. I kept a bunch of homebrew stuff in our shed when we first moved here but everything got chewed, there's now lots I have to store inside. I've heard stories of rats chewing their way into plastic tubs... so I bought a big metal dustbin to store grain in the shed when I got my grain mill last year, the lid doesn't clamp completely tightly so I weight the lid down. Ain't no rat gonna chew through that...
I think I got this one
