There's a rat in my greenhouse what am I gonna do?

It has been quite a long freeze this, got to -5°C last night. The plot is pretty solid and covered in icy snow so not much to be done there. However, the greenhouses are getting to toasty +12°C during the day so sowing stuff is going to plan.

Got to the plot today and found some vermin had managed to tunnel into one of my greenhouses and run amok digging up pots looking for tasty seeds. The little sods managed to dispatch a few healthy pea and cauliflower plants I had going, but totally wiped out the broad beans I had sown. I have now resow the broad beans!!! This has happened before, so I just find the hole block it off with some heavy bricks and should be ok....fingers crossed

Also put new onion sets in seed trays..not much else!!!

Bloody pea killing vermin!!!!
