Rethinking Hackberry Trees

This summer and early fall, we've had a major infestation of Asian Wooly Hackberry aphids. At first it was just a nuisance...looked like a few snowflakes. Then the moldy aphid dew covered DH's truck parked under a hackberry, and now the dew (don't do this dew) is going to be a major pollutant on DH's garden railroad. Every plant within dew distance of a hackberry tree now has leaves covered with sticky black. The hackberry trees are visibly black from a distance.

We have been repainting our house and the bugs add a tetural element that we'd rather not have.

I've seen problems in Nashville, as well.

From reading references on Google, there's no practical solution that can return the Hackberries to looking even slightly clean by fall.

We are probably going to have to remove the hackberries near our house just for cleanliness.

We've got so many hackberries out in the woods that even if we were to wash our trees with insecticides (and this is NOT a solution, as we depend on beneficials whenever possible) there are hoards of flying aphids ready to move back into our trees and recoat our world with black scum.

Is anyone else dealing with this problem, yet?
