University of Delaware did a study on DE and found it ineffective as a wormer. The researchers theorized that when the DE was in the digestive tract it was wet and that prevented the De from cutting the worms up. The abrasive cutting action is thought to be the reason it works on mites and external environment pest. In slugs we are sure that it is the cutting action that destroys the slug.
I'll get the name of the head of the study head and post it on this thread.
For those of you who are interested -------It was Dr. Bautista. of University of Delaware, who did the study.
