Subterranean activity in the polytunnel.
Over the winter there are more and more tunnels appearing beneath my poly tunnel soil, and the access holes are getting bigger!
We do have moles here, and mice take any peas or beans sown direct so I always sow in pots.
However this is getting silly! There is now more tunnel then soil in some places.
Any ideas on how to identify the culprits.
I can not see any rat droppings which would be my primary concern, however the size of the access points seam too big for mice.
