Hügelkultur garden bed, using free and recycled materials

Not in every climate. Also if one has a wood chips mulch on the surface in the garden would that not attract the termites anyway if they happen to be around?

Not saying it is not a problem, just that "it depends". In this [Self Sufficient Me](https://youtu.be/3O2qCQU7Cac?si=i52YgphiViqiu0BV) video from AU the author was happy with the hugelcultur but in the comments someone mentioned rodents/rats burrowing under.
