Pest description and crop damage Slugs are active above ground primarily at night, and also during mild, wet periods at any time of year. Very little activity takes place in cold, freezing, or extremely hot weather. During the day, slugs usually stay in the soil or in crevices or cracks in order to protect themselves from dehydration and predators. Slug damage can be distinguished easily by the presence of slime trails. Slug damage tends to be heaviest along field margins. Weedy or grassy borders serve as excellent habitat for slugs.

Management-chemical control

Fall baiting usually is recommended for non-irrigated crops. Apply bait after the first rain showers, when slugs become surface active. Bait applied immediately after the first fall rains kills a large population in the field.

  • metaldehyde baits
  • sulfur baits
