Originally introduced from France as a source of food to humans in the 1850’s, snails and slugs are now one of the biggest pests and can do much damage to a garden or landscape. Snails and slugs are biologically similar, except snails possess an external shell. They travel by gliding along a muscular “foot,” which emits a constant mucus.
