Sap? Dripping from tall oaks

Asked August 3, 2019, 7:29 AM EDT

Reading info from an article I see the "sap" is most likely honeydew excretions from aphids. It is a dripping sticky mess below on patio and cars! These are massive trees. Any way to control this. Will it harm the tree?

Hello -

We need some more information before we can answer your question. Can you send us a photo of the sticky mess? Is it possible to get a close-up picture of the oak tree's leaves?
