Are they clear with two little spots like a saddle on the adults ?
Those are the ones from hell and you really need to stay on top to get rid of them.

I would most likely bomb with an pyrithrum bomb. Pyrithrum is all natural and will dissapate in about two hours then let them continue drying for a few days just to air out.

If your going to keep growing in the same place you need to do what I'm doing. Cleaning and spraying the whole place using Azamax. All plants in the mother room sprayed and azamax added to the rez water to be an antifeedant. Then all clones will be dipped in a solution of azamax. I have had a hard time completely getting rid of the buggers but this plan will work.
