Hi. You said that the castor oil would not kill the parasites anywhere but in the intestines. I have been wondering this for a few days now, if the Humaworm doesnt get every last parasite/egg, wont they just lay new eggs and the vicious cylce begins again? It seem like fleas, you could clear the whole house, but even if a few of them survive, you will again have an infestation. Just like fleas, there are some parasites that lay THOUSANDS of eggs a day, right?
