Bifenthrin works best for us here in Mexico, I have used Lorsban to keep it at bay it but the miteicides work best.
They re-populate pretty quickly so it is best to do a back up spray within a 7-10 days...
We have a dry climate (approx 2-4 inches a year) so it can get bad in stressed areas.
I am sure you are seeing that "witches broom" or "bunched look" in the effected areas, that is normally a good sign they are around.
