Most species of slugs are generalists, feeding on a broad spectrum of organic materials, including leaves from living plants, lichens, mushrooms, and even carrion. Some slugs are predators and eat other slugs and snails, or earthworms.
Snails and Slugs. Snails and slugs are among the most bothersome pests in many garden and landscape situations. The brown garden snail is the most common snail causing problems in most home gardens; it was introduced from France during the 1850s for use as food. Several species of slugs are frequently damaging, including the gray garden slug, the banded slug, the tawny slug, and the greenhouse slug. Both snails and slugs are members of the mollusk phylum and are similar in structure and biology, except slugs lack the snailâs external spiral shell.
