Damage caused by slugs 1 Slugs use file-like mouthparts (called a radula) to rasp and chew plant tissue. 2 Because of their mouthparts, they create irregularly shaped holes in leaves, flowers and fruit. 3 Low to moderate feeding can affect the appearance of plants but usually does not impact plant health. 4 Severe slug feeding can injure plants, especially seedlings. 5 It can also reduce the harvest of fruits and vegetables, especially when plants are young. Older plants are more tolerant of defoliation.

In the United States, the Pacific and Atlantic coastal areas are prime regions for slugs and snails, with the Pacific Northwest, tropical and subtropical Hawaii, and Florida especially hard hit. But even gardeners in cooler, northern climates are threatened by these pests. From Maine to Minnesota, slugs and snails simply wait out winters in hiding spots that protect them from freezing.
How Do Slugs and Snails Harm Plants?
Slugs and snails feed on living and decomposing plant material, but they prefer young, tender plant growth. Newly sprouted seedlings and soft growth on established plants are often the first targets. Lettuces and tender herbs, such as basil, are also favored, as are foliage plants, such as hostas. As slugs and snails feed, they create large, irregularly shaped holes. Unlike the rough, uneven edges left by many chewing insects, slugs and snails leave very smooth edges.
Why Should I Control Slugs and Snails?
While one or two slugs or snails may not seem like much, populations can increase quickly. Slugs and snails mate, but they have both male and female reproductive organs. That means every slug or snail can lay eggs. Common snails may lay up to six egg batches annually with as many as 80 eggs per batch. 2 Some slugs lay up to 500 eggs per year, which mature in three to six months and start laying eggs themselves. 4,2 Left unchecked, that's hundreds of new pests each year, multiplied by every slug or snail in your garden.

What do slugs eat?
Slugs eat a wide array of broadleaf plants and grasses, including most crops and many weeds. They harm crops both by killing seedlings outright, causing poor stands, and by damaging leaves on young plants. They feed by scraping the surface of their food, which can include seeds, roots, stems, and leaves. The appearance of their damage varies by crop. In wheat, slugs feed on recently-planted seeds, hollowing them out and killing them. In corn and many small grains, slugs scrape strips in the leaves, leading first to window-pane damage, and then to leaf shredding (Fig. 7). In soybeans, slugs create craters in the cotyledons (Fig. 1), and then ragged holes in the leaves. Similar ragged holes are seen on slug-damaged canola, alfalfa, and other broadleaf crops (Fig. 8). Slime trails are often seen in close association with their damage. Seedlings are especially at risk when the seed slot is left open, creating a dark, cool slug "highway" leading right to the next seedling.

What are the slugs that live in Pennsylvania?
Of the 20 or so slug species that occur in Pennsylvania, four are common in field crops: the gray garden slug ( Deroceras reticulatum, Fig. 1, 2), the marsh slug ( Deroceras laeve, Fig. 3), the dusky slug ( Arion subfuscus, Fig. 4), and the banded slug ( Arion fasciatus, Fig. 5). While the relative importance of each species is not well understood, the gray garden slug often occurs in the largest numbers and is most often associated with crop damage. This is a medium-sized, light to dark gray slug that produces sticky, white mucus when disturbed. All of these slug species were introduced from Europe with the exception of the marsh slug, which is thought to have mixed native and introduced populations.
What are slugs' relatives?
Slugs are close relatives of snails - essentially snails without a shell. They are legless, soft-bodied creatures with four front tentacles and a covering of slimy mucus all over the body. They secrete this mucus wherever they go, leaving a characteristic "slime trail" that can be a valuable clue of their presence. Different species vary in color and pattern, but all are various earth tones such as gray, brown, or orange. Again varying by species and age, slugs can range in size from a fraction of an inch to several inches. Juvenile slugs resemble adults but are smaller. Slug eggs are small, gelatinous spheres or ovals found under residue or in the soil (Fig. 6). The eggs are often found in clumps but may also occur singly.
