I have found that after taking killing antiparasitic meds (Moxi, FenBen) that there IS increased activity. I have come to believe that they have been threatened and are attempting to breed quickly. As I kill them over time, I have fewer and fewer vibrating/buzzing (mating call) parasites following dosing. Just now killing the last ones(hopefully) in my face (eyes, sinuses, facial and neck muscles) after completing some dental work (reducing infection sources). I can tell because the little skin tags are drying up and I have some puckering on my skin and almost no activity following dosing. Taking LOTS of collagen which is helping.
