try using a 2:1 mix of ISO alcohol and 1part water in a spray mister--right before the sun goes down spray them good --under leaves --on top of leaves stems and top of dirt---the alcohol evaperates fairly quik and kills a lot of different bugs and mites--repeat 2-3 times in one week---DO NOT spray on hot full sun leaves it will yellow them--early evening is best--just before dark...hope this helps
