Cankerworms/Acer palmatum ‘Bloodgood’ question???

Hi everyone. I’m new to this forum and I’m looking forward to learning from you’ all and contributing as much as possible to this great forum. :D

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. :cry:

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!
