Answer: Euonymus shrubs are subject to a number of pests such as scale insects. Unfortunately based on the information in your question I am unable to determine exactly what is happening to your shrubs. I would suggest you work with your county extension to obtain a specific diagnosis of what is affecting your plants and based on that, how best to treat them. They will also have the most up to date recommendations on what to use and how best to apply it if it is something that needs a chemical control. Good luck with your shrubs!
