Prolonged use of Wormwood can possibly create a psychotic state so lay off for now - rotate your protocal - keep 'em confused. I use DE and they are sliced and diced and dehydrated, and digestive bitters flush the liver naturally evicting them, and MSM can help them let go. Build your intestinal flora so it won't be so comfy there for unwanted company. Really - stop the Wormwood .
