|The least toxic solution would be Insecticidal soap, I think. Very difficult to do with a tall tree. I use a pump sprayer, but it's not easy reaching the high branches, and you do have to cover up well, when getting under the tree to get the undersides of the leaves. Always spray when cool and no breeze. LOL! Yes, I know, Try early morning.
