The remedy for mites infestation is a topical application of saturated borax in a 1% hydrogen peroxide solution. Plus I would add 1/4 or 1/8 teaspoon of borax in a one liter of drinking water. Or if some people have difficulties, 2-4 tablespoons of borax in 1 cup of hydrogen peroxide solution. I would allow a couple of minutes for the solution to dissolve as I stir the solution and will apply to the area of the skin.
This is the only one remedy against that has worked for me well and it also worked well with the dog mange. Originally the dog mange remedy was actually a remedy I used for mites infestation in the past. There are other remedies that may work just the same, but this is the simplest one.
