Thanks. The problem is, the worm is not always there. They only come up for a few seconds after a shower. They don't even come up with every shower. What do you know about cycling the parasite herbs? Humaworms says to stay on herbs for 30 days, but I read you need to do 10 days on 5 days off 10 days on 5 days off for 2-3 months, in order to kill mama's, babies and eggs.
