From Indian Summer Honey Farm:
1 Pint Tea Tree Oil + 4 Pounds Thymol Crystals + 1# Menthol crystals +21# powdered sugar +3# Crisco shortening = mite treatment
In order to make this treatment we warm the shortening in the kitchen oven until it is liquid. Then we pour the liquid shortening into our mixer along with the Thymol and menthol crystals. Once the crystals have melted we add the Tea Tree oil and sugar. It is then mixed until smooth and creamy. Should be like cake frosting.
