They are a mollusk, like oysters, clams and snails and can be described as a snail without a shell. Slugs are one of the first pests of spring. They hatch from jelly-like masses found under boards, flower pots and other damp areas of the garden. Slugs feed at night and leave behind a slimy residue as they move. They prefer damp, cool locations.
Slugs eat large holes in the leaves, fruits, and crowns of plants.
Eliminate hiding places by removing garden debris such as leaves and mulch. Increase spacing between plants to allow better air circulation and reduce moisture that the slugs need. Hand pick at night or in early morning. Use barriers such as coarse sand or copper stripping placed around desirable plants. Attractants such as stale beer in a shallow dish may attract and trap some slugs.
