Arion spp., Deroceras spp., Limax spp.
Pest description and crop damage Slow-moving, slimy animals without legs. They may climb canes and move onto berries, and become a contaminant at harvest time. They are most likely to be a problem in cool, wet summers. Slugs migrate into and under crates taken into the field before harvest; keep crates and pallets away from damp soil and grass.
For best slug control, bait after the first extensive late-summer rains, which activate the slugs. Baiting at this time kills egg-laying adults that would produce slugs next spring. Apply bait on the soil surface around plants. Do not contaminate berries or foliage with slug bait.
