The thing that bothers me about a soap solution is that these leaves are curled
up, almost like a small cocoon. The soap spray would have to actually land on
the underside of these leaves to do their job. That's why I think the chemical
approach
may have a better chance of getting them.

Thanks for the tip - I gave it a good drenching yesterday, so we'll see
what happens.
