Robin Red & Maple pests

Eileen Griffin asked 6 years ago

I have a Robin Red and a golden maple next to each other. Both are covered in a tiny black insect. On the maple the insect appears like black spots on the leaves. On the Robin Red the insects are grouped on the stems. What is the best way of treating this? Thank you.

proably just harmless flies resting there…no fly attacks both shrubs.
