Description and Biology of Slugs

Slugs are stealth pests that feed at night so farmers usually do not see the culprit damaging their transplants. In the field, farmers can provide habitat for toads which help control slugs but since this is not an option in the greenhouse, other strategies must be considered. The kaolin clay product Surround® has been shown to be very effective against slugs. Surround® is OMRI-certified and approved for organic production. (See Pesticide Use Guidelines).
