What ever it was chewed holes in the netting bags covering the module trays. I had 8 runner beans in one tray and filled it up with 4 broadbeans and whatever it was ate all the broad beans and did not touch the runners.
I only know the squirrels like broad beans I have watched them eating them. But this time I have not seen it. But a few weeks ago we have a squirrel down our chimney. It was luckily blocked by a spark guard. I was trying to figure out how to get rid of it without it escaping into our sitting room.
I left while I thought about it, but when I came back it had gone, presumably climbed back up the chimney.
