Worms on my rose bush
I noticed the leaves on one of my knockout bushes had silvery stripes on them or blotches. When I looked at the bottom of the leaf, I saw tiny grayish worms. What can I put on my rose bush to get rid of the worms? I picked off the leaves I could and destroyed them. I also saw some holes in some of the buds. Is there something safe I can spray on them to get rid of the worms?

Do they look like these rose slugs?

Curled rose slug larvae are metallic green above, marked with white dots, grayish white underneath, with yellow-brown heads. They curl up like a cutworm and are about 3/4" when mature. Curled rose slugs initially feed by skeletonizing the leaves, but eventually defoliate entire leaflets except for the largest veins.
