Q.Excessive sap and wooly aphids on Hackberry Tree
More recently, the sap has become abundant and the aphids are everywhere. In years past, we had many ladybugs here but not seeing them as often now. Tree is about 35-40 feet and hangs over my beautiful deck. I am having to rinse the deck daily, as it is so covered with sap that your feet stick to the decking. Is there a way to treat the tree during spring? We had some sap in the years past but nothing like it is this year. We have had excessive rain this year. I live in NW Georgia.
The 'sap' is actually called Honeydew, it is the secretion from the insects.

Normally Neem Oil can be used to treat the insects but a tree the size that you have would be difficult without a professional.
