I tend to use the least toxic method of control and only go to stronger means when they have not been effective. In my hot, dry climate, scale and mites are a constant problem, that is why I treat on a regular basis (every 2 weeks) with a horticultural oil. I like Sunspray particularly. It is 100% parafin oil, non-toxic and kills by suffocating the pests. When initally treating an infestation application every 5 days or so for the 1st 15 days may be necessary to kill new hatchlings.
