Home & Garden Mimeo #HG92 Slugs & Snails

Slugs and snails can be troublesome pests in the garden. There

are many species of these mollusks, but only a few present a

serious problem. Some of these are the gray garden slug,

Deroceras reticulatum, the tawny garden slug, Limax flavus,

the spotted garden slug, Limax maximus, and the brown

garden snail, Helix aspersa.

Slugs and snails have limited protection against water loss and

need adequate moisture levels to survive. They can absorb

water directly through their skin or drink from puddles. Slugs

and snails feed primarily at night, although they can also come

out during foggy overcast weather, after rain, or after water-

ing.

During the day, they seek protection from dehydration in cool,

damp locations under leaves, mulch piles, rocks, stepping

stones, wooden boards, porches, decks, crawl spaces, or

flower pots. Large populations can sometimes be found under

groundcover plants such as ivy, pachysandra, and vinca.

Wood chip mulches also provide excellent habitat. tend to avoid crossing dusty or dry materials. The shiny dried

slime trails left behind on plants or along the ground are good

indicators of their activity.

Damage - Both eat large, ragged holes in the leaves of plants

and may also completely consume young seedlings. They

begin feeding early in the spring and continue through the

growing season until frost. Slugs and snails feed on a wide

variety of plant material and can be especially troublesome on

hostas, violets, ageratum, strawberries, lettuce, and cabbage.

Life Cycle - Slugs and snails are hermaphroditic animals.

Each individual has both male and female sex organs, but they

usually require another individual to fertilize the eggs that

each carries in its body. Each one is capable of laying a total

of about 300 eggs. These are laid any time conditions are

optimal, but peak times are the spring and fall.

The gel-like eggs are laid in clusters of 25, about an inch

below loose soil in damp locations, and are covered with a

layer of mucus. Eggs hatch in about 30 days. However, under

Slug eggs

Slugs and snails travel by means of a large foot that glides

over a trail of mucus or slime, secreted from glands located

under their head. The slime provides a cushion over rough

areas. This slime also serves as a trail marker. They return to

their favorite hiding and feeding places night after night

unless disturbed or the site becomes too dry. Slugs and snails
