He is a fellow friend and canadian who used a shampoo called nyx to get rid of mites.
As for the burns use a watered down solution of betadine. Like foschi said soak her in the bath but add betadine to the water to make it a almost tea colour. You can pick betadine up at a pharmacy.
Also like foschi said. Do not treat for me mites UNTIL you get her burn wounds closed and somewhat healed so no chemicals get in it from treating the mites.
