I agree those raw seeds are not only tasty but also extremely effective. I think for me they definitely make my worm family sick but as far as expelling them I haven't had any luck. That's why I thought the oil might be a little more difficult to avoid seeping down into my stomach similar to black tar. Covering them and smothering them.
You might be correct about the toasting making it not as effective but I enjoy throwing anything and everything at them. I'm hoping that there is still some of that element remaining in the oil that they don't enjoy. I also felt that my system might digest the oil better since nuts are known to be difficult for humans to digest.
Thanks for the tip and appreciate the feedback.
Maybe being in the spirit of Halloween it is the time to give all our worms some extra pumpkin seed treats.
