A little recipe I stumbled upon. Dyna-Gro Pro-Tekt (emulsifier) 1/4-1/2 tsp,with the following essential oils in a gallon of water Lavender oil 3ml, Rosemary oil 3ml, Peppermint oil 3ml and Aloevera oil (surfactant) 3ml. Shake well and spray under and on top of leaves just before lights out. Plants respond to it too. 2-3 times/wk then as needed. good luck. Kills adult mites and melts eggs. no harm to plants.
