I’ve seen slug trails on my patio this past week but so far no plant damage. Slugs are related to snails but have no shell, so they aren’t as cute in pictures. They are active above ground, mostly at night during cool, wet weather. When the sun is out slugs hide in cracks and crevices, under plants or in the soil to protect themselves from dehydration and predators.

Slugs are easy to detect because they leave a silvery slime trail. The damage they cause can be to roots, stem or leaves. Damage to foliage is sometimes at the edges of the leaf but usually is seen as irregular holes between the veins. Damage on the roots or the stem is seen as a smooth sided pit.
