Not sure what to do next with new termites and isopods.

I recently decided to clean up and redo my dead moss terrarium. I'm trying to keep everything low cost or found. I started with a small piece of my pathos plant. Then I decided to go find some stuff in the park. And along with some small plants (unknown to me) and soil. I grabbed a cool piece of wood.

I knew there would be hitchhikers on the piece, but didn't want to get rid of them. Little did I know I got small group of termites and in the three days since I added the wood, they have gone to town creating their tunnel network. I don't really mind them in there, but I'm unsure what I should do next. Do they just continuously dig until they die? Should I remove them? If so is there a way to do without completing starting over?

There were some isopods on the wood too and they seem okay, but I'm wondering if I need to add more food or remove a few.

Should I add other creatures or fauna?

Any help is greatly appreciated!
