Hi, arborist here. I would advise against using pesticides to control this issue. The galls are completely harmless to the tree and the pesticides may cause harm both to you if you were accidentally exposed, and definitely to other invertebrates, many of which may be beneficial. Some may even help control the mites in future years.
Great, that’s basically what I’d recommend. Disposing of any leaves you pull off the tree and those on the ground away from the tree should help reduce the intensity of the issue.
Great! Thanks so much!

Thanks. I think what my mother will do is just pick off the affected leaves that are really bad and leave the rest.
