Getting rid of Aphids on your trees ...
Use Bayer Advance Tree and Shrub Insect Control.
I've used this stuff and it really works well and works quickly. I used it on two large bur oak trees and it did the job. Not only that but it wasn't necessary to use it each year. I believe I skipped about 4 years before I had to use it again.
I highly recommend it. It is rather pricey though especially for large trees.
And, just so you know, I have no connection with the Bayer people. They have no clue who I am, haven't paid me to endorse their product nor have they asked me to endorse this product. I tried it and it surprised me that it worked so well.
