What you need to do is take herbal Oregano of oil pills. This will kill the large ones, but once they die they release the little ones so you MUST take clove continuously after taking the Oil of Oregano. Put skin applicable eucalyptus oil on your anus area esp at night. You have to control the tiny eggs or babies from moving from your anus at all times or they will crawl over your skin and into your scalp and deplete the nutrients in your hair causing dry brittle hair and stunted hair growth. Rinse scalp and skin with witch hazel or Listerine. Use eucalyptus oil in laundry.
