The "curative" treatment is two treatments at 1 teaspoon per gallon with a 7
day interval.
Definitely drench as well as spray.

Oh, I have some. Cheaper than having scale, I'd wager. And it is cheaper
now than when I bought it... Mine is pretty old (4 years maybe?). Don't
know if it is still any good. Worked great on mealybugs when I was
growing under lights. Haven't tried it in the greenhouse yet. So, Ray,
how many sprayings of Enstar II and what concentration? I don't recall it
being systemic, so do you do a drench of the potting material as well?
On the advice of the bug company, I'm going to try green lace-wings on my
orchids. The adults don't eat much of anything except pollen and nectar,
but the little baby lace-wings are voracious. They mainly eat aphids (I
have seen a few, not many), but also anything else that they come across.
Not terribly expensive. And, since the larvae don't fly, they stick
around longer than ladybugs.
