Mice usually wait until they see a shoot and then dig down and eat the pea

little holes in the soil where germinated peas should be but no actual peas.

Yep, that sounds like the one. I've closed the greenhouse vent, but I doubt it
will stop them.

Funny, but last year we had no trouble with mice at all on our ground sown
peas so I didn't use the grow in guttering system this year but we have lost
the lot now. Our experience here is only early peas work well, maincrop ones
get too hot/dry and never produce a decent crop.

Well we /are/ using guttering, and it's not stopped them. :-(
