My husband became infected about 3 years ago. It was before me. At this time he feels he is only internally infested. He's used ivermectin for several years now and vibazen off and on. He's about to start the Vibazen for the three months like you did. How will he know if they are truly gone? How can identify the nests to have them cut out? Who does that? I am also going to have him take serotonin boosters and ant crud 6 to help with the mental side effects. He feels he's never going to be free and it kills me. He feels that a rife machine at certain frequency fries them. We have been together for two years and I have never seen mites. Only the mental anguish. Any help is appreciated. Thank you
