How to treat Gloomy Scale on maple tree?
We've been told we have gloomy scale on our maple (urban setting). What's the best way to treat this? We live in the Rogue Valley (Phoenix, near Medford). Do we need to use a trained Arborist for this procedure? Or? Thanks, Michael.

I have not gotten any responses from entomologists yet. Will post if I hear something.
