Aspen tree

Asked June 4, 2014, 4:09 PM EDT

The leaves on some of my aspens are getting covered with wart like growths. Some others are being eaten by bugs that roll the leaves into sort of a cocoon.
What can I do to treat the trees.
I cabn provide pictures if you need.
Thanks,

Summit County Colorado
