The best cure CURE i have found is to dessicate (dry) them to death
If the infestation is real bad i hit the plants with 50/50 90%alcohol and water with a few drops of dish soap this WILL burn some leaves but who cares .
Also spray the room (dont smoke

) to get any strays
Then i follow up with a 1/4 mix alcohol and water with soap this will NOT burn your plants (didn't on mine at least)
And spray with that mix for a week straight
And they will be gone
Very important to spray every day to kill newly emerging hatchlings and missed eggs.
If your plant is able to be dipped
I recommend dipping them to really get them all off.
Just use the same 1/4 mix and fill a bucket high enough to dip the whole plant down to the crown .
Worked for me .... but i never tried with plants in bloom as im sure the alcohol would melt off some crystals
