Answer: Unfortunately, based on your description, I am not certain what insect might be on your tree. You need to have a specific identification of it before deciding what to use to treat it. I would suggest you consult with your local Rutgers extension for help in identifying it and determining how to proceed. I should also mention that cherry tree bark often has natural little dots or bumps on the surface, so you may want to double check and make sure that what you are seeing is truly an insect and not just part of the bark.
