It looks big here but actually it is about the size of my index finger nail. It leaves a slimy and shiny trail on the leaves. Should I get rid of it?
Oh yes definately get rid of him and any others you see Songlim. They can munch their way through your plants in no time at all. Snails are definately NOT one of the creatures I'm happy to have in my garden.
I kill those on sight, and their relatives without houses too. I've got a personal record of more than 500 killed in one evening.
