response: Good Evening, Looks like maple spindle gall.  The infestations are unlikely to be controlled by chemical treatment. By the time galls become noticeable, the causal pest is confined within the gall and physically protected from chemical sprays. Attempts to control many plant galls may result in more harm to the plant or the environment than good, while achieving little actual success in eliminating the gall problem on the plant.  Although unattractive, galls will probably not kill your tree and usually natural controls will reduce the population in succeeding years.
