there seems to be a worm like insect inside of the leaves. How do I get rid of them. Now I am going to cut it down and get it ready for Winter but I am sure they will come back. This is my first time planting Hollyhocks
This sounds like leaf miners. Make sure not to compost the infected plant. Here are control options: https://www.gardeningknowhow.com/plant-problems/pests/insects/leaf-miner-control.htm
If you decide leaf miners are not the problem, please submit a picture of the affected plant leaves.
