The White-lipped Snail or Garden Banded Snail, Cepaea hortensis is common to gardens across Europe and the northeastern USA.
They're easily identifiable from their yellow shells with brown banding and a white edge around the base.
This species is found during the daytime, most often in damp, moist conditions or hidden away in greenery.
They favour plants like nettles, Ragwort and Hogweed, but can sometimes be found grazing on other garden plants. Damage by these snails is ever only mild to moderate.

Biological treatment
Pick snails off plants with fingers and move them elsewhere. Slug and snail traps can be an effective measure to snare slugs.
Diatomaceous earth, a fine powder that is very sharp microscopically and the edges easily cut through slug skin and desiccate them as they crawl over it. Replenish it after every rain or heavy dew.
Other barriers include hair, eggshells, soot and wood chippings.
Chickens and ducks will eat any slugs and snails that you have in your garden.
Attract these garden predators to your green spaces by incorporating small water features (for toads) or habitats like log piles and shrubs for hedgehogs. These animals adore wild patches of grass and dense undergrowth. Here, they can stay concealed. You’ll require some exit and entrance points in the garden, too.
Attracts
Plant nettles, Ragwort and Hogweed to attract snails away from other garden plants.
