Gardening expert David Hurrion explained in a video for BBC Gardeners’ World which slugs do the most damage.
He said: “If I was to ask you what the number one pest problem was in your garden, you’d probably name these little ones: molluscs.
“These are the ones that do the most damage. These are the slugs, but could I just put a good word in for the really big slug?
“These great big, huge slugs are the ones that break down woody matter, and they won’t eat your little baby plants.
