Worms (canker?) on trees (Red Oak & Cedar)

Asked September 14, 2020, 12:08 PM EDT

I sent the following note to the Mecklenburg Lawn & Garden (Horticulture) Help Desk, but without photo. This note has photos attached. Need help dealing with small green worms (fall cankerworm ?) that are on a red oak and a cedar (angel cedar or cedarus deodara ?) tree. They're stripping the leaf between the veins and the needles on entire branches. I understand banding is not especially effective and it's a bit late for this crop of worms. Can the trees be sprayed? If so with what? The worms move like typical inch worms, with a humping movement and have three pairs of legs on one end.
