Aphid control- need a rethink
Have you considered using a paint sprayer? You'de get your volume, all
right, and it would be much, much easier! You can often rent one from a
hardware store. I use one to clean the trees and bushes here - the
force is enough to blast off bugs with just water. If that doesn't
work, a little soap often does - though I only had to follow up with
soap twice.
