Bifen XTS is not labeled to kill snails. Snails have a mucus covering their bodies which protects them from most liquid insecticides. You should choose a product that is specifically labeled for snails such as Monterey Sluggo Plus Slug and Snail Killer or Fertilome Natural Guard Bug, Slug and Snail Bait.
