Common Garden snail
We've had 1500mm of rain this June/July 2015, and so I've seen a huge increase in these little snails. They can be found everywhere from the sides and crevices of outbuildings on Garden stakes even found at the top of tall grasses in the fields. I have had to be diligent in combing the garden beds for them on a daily basis to keep them under control. I have found them predominantly under the leaves of cucumber and DAIZU.
