Answer: If you see glistening trails of slug slime, then yes, it is slugs. This year there are also many earwigs about and they cause a similar damage. Both of these pests work at night so you won't see them. Slugs can be trapped or picked off at night, or deterred with diatomaceous earth or Sluggo. Earwigs can be trapped in rolled up and dampened newspaper or cardboard tubes set out in the evening and emptied each morning. For both pests it is a good idea to avoid evening watering as they like that moisture.
