I've been reading that a few of you use pumpkin seeds for worm control. I've got a couple of things I'd like clarified if possible so I can give it a try. - I presume I'd use raw pumpkin seeds, not the roasted pepitos, right? - will any pumpkin seed work? Fresh, dried? - and finally, do the seeds need to be chopped up or can they be eaten whole? Thanks. I'm always looking for the more natural, less invasive ways of keeping my 4 girls and their handsome man healthy.
