I'm having issues with worms eating my leaves of two Mountain Laurel bushes. They are covering some of the leaf ends with very small webs. The worms run from just over 1/4" to just over 1" in length. The one in the image is ~1" long. I used Seven Dust that seemed to keep them at bay until they get watered. Found a few this morning. If I catch them in time, I can pinch them off but sometimes the damage has been done. Any ideas for protection?

This looks like a genista caterpillar, Uresiphita reversalis, in the family Pyralidae. It is a common pest on mountain laurel; see https://landscapeipm.tamu.edu/ipm-for-ornamentals/genista-caterpillar-on-texas-mountain-laurel/ for some management suggestions.
