Box tree caterpillar

When I was cleaning windows, my eyes fell on a very miserable-looking boxwood. I looked closer and was shocked by the number of caterpillars in the bush. It immediately became clear to me that the box moth had also settled in my garden and was doing well in the turtle, bear, and hedge in large numbers.
First I tried to find easy solutions to the beast on the Internet, but couldn't find any. Then I started cutting the ears of my at least ten years old box bear. And the rest of it followed.
It is a lot of boxwood waste and it cannot be put on the compost pile. We have not yet cleaned up all the boxes. It is a lot of work.
