I have a golden raintree that is covered in sap balls. There is a little beetle type insect under each flow of sap. What is it and what method would be used to get to them under the sap? The only way I can think of is some systemic insecticide if such a thing exists, and that would take a long time to spread around. Should I even worry about it?

Sounds as if you have a serious problem. I think what you have are Shot Hole Borers. Google invasive shot hole borers and see if its not the same thing

The name sounds right from the perfectly round small hole.

I see no reason to think you are wrong. They eat oak too. Guess what tree is all around my house? It might explain a few quick and unexpected deaths. And guess what! They come with a fungus! Fusarium euwallacea.

I am fully pissed off. There will be a bio-war.

I contacted the county agent. Not an unknown problem here. Usually crops up in droughty conditions as we have now. The agent recommended a tree injecting arborist who will be here Monday.

Thanks @Chuck!
