I use Rosemary, mint, clove and neem oil. .5 tsp per gallon, pro tekt silica at .5 tsp per gallon, 2 oz of aloe Vera juice and 1 tbsp per gallon of dr Bronners. Works for bugs and pm. When I was doing indoor only I'd make a tea with fresh mint, rosemary and cloves then add the pro tekt, neem and dr Bronners with the pulp from 1 filet off of my aloe squeezed in. Now that I'm doing things on a much larger scale I use the oils and aloe juice. If mites are a big problem and you don't care about organic, forbid 4h is the best I've used or seen.
