Out doors are always a challange with catipillars, vigilance is your best defence, nats are sometimes associated with too wet of conditions, if in pots wick them. Just get an old cotton tee shirt, cut strips, carefully run them into the seep holes by tieing the cotton wick to a wire clothes hanger. This will help you deposit it deep in the pot, those long match holder things that you might have seen used to light the waterheater works pretty well also. Outside that, when it comes to pesticide in our bodys less is more!
For spidermites, DO try cali clean, see thred. This stuff is also dynamite for burned and otherwise people screwed folliage, works like a bandaid, Starts n deficiant pale leafs greening within a couple hours of spraying. I use this on all sick plants . It's medication for OUR medication!
