Alfalfa hay-Slug

Pest description and crop damage Snails and slugs are nocturnal and generally feed during the night damaging many varieties of plants and plant seedlings. They inhabit damp, moist areas around decaying refuse, organic matter, and hide at the base of growing plants. Their presence can be detected by the shiny trails left on the soil surface. Damage is to new seedlings and primarily to hay grown west of the Cascades. For additional information, see:
