Rats

I took over a plot in a very rural location, I also live in a rural location so know about rats, or thought I did.
The plot has been growing well and for a first attempt I’ve been very pleased. I had some beautiful sweetcorn coming along which we were very much looking forward to, I went away for a weekend and came back to it having been totally stripped. I checked all boundaries thinking it could have been badgers (we had been warned) but the boundaries were sound. We then started getting long humps, a bit like speed bumps all over the paths under weed membrane and woodchip which collapsed when you walked on them. I then noticed activity around my compost. So I lined my second bay with wire mesh and turned the first bay over to the 2nd bay. Today (2 days later) I uncovered the compost to add more and had a couple of rats jump out. So I turned it again and you can see all the runs under the mesh. It’s awful and to make matters worse I’m terrified of mice and rats!!
I can’t put poison down, any suggestions that will seriously work please.
Thanks

I found traps like these very successful. Baited with peanut butter. Screw to a piece of wood. Long piece (12" at least) so you can carry it to the bin press the back down. Rat will fall into bin, without you touching it.
