An infestation that's really bad, do an initial 3 step treatment. First, spray with a contact killer (neem,
pyrethrin, insecticidal soap) to kill as many of the bugs you can that you're about to disturb. Wait about an hour for th contact killer to kill.
Then get a hose with a good strong mist but not so strong it will damage the leaf tissue. Spray the whole plant down and wash those bugs, their bugshit and their eggs off of the plant. Tilt your pot while you are working so you don't drench your soil, or throw a garbage bag over the pot so the water doesn't hit the soil.
Let the leaves dry and then apply a treatment of Captain Jack's. Reapply in about 7-10 days, and continue inspecting and spot treating and manually removing any bugs that return.
If you grow outdoors, my advice is don't wait until you see signs of pests. By the time you see them - especially mites - it's too late.Treat for prevention
