I was wondering if anyone knows if cankerworms defoliate Acer palmatum ‘Bloodgood’ and Prunus yeodonis ‘Yoshino’ trees?
The reason for my concern is that we just built a house on a lot that has several mature Norway maples around the perimeter of the property and they are badly eaten by cankerworms this year.

I would love to plant an Acer palmatum ‘Bloodgood’ and a Prunus yeodonis ‘Yoshino’, but I don't know what to do about our cankerworm problem.
Are these trees on their menu, if so, is there any natural enemies or chemical control I should look into?
Thanks!
