My crepe myrtles are as tall as my house. What is the spray formula to address aphids on a larger plant like this? I tried spraying them with a garden hose, but that didn't solve my problem.

Consider using a ladder to get closer to the infestation. Use horticultural soap or neem oil in a sprayer connected to your hose. Treat the crepe myrtle early in the summer as soon as the aphids are present and retreat every few weeks.
