As I mentioned in the post and to other commentators, while aeration does help plants in gardens and compacted soils, it's actually harmful to forests- it all comes down to context.

Is there anything we can do to put out those evasive earthworm who is bit by bit destroying the forest?

Not really, unfortunately- we can just do our best to keep them from spreading too much farther.

It's possible to introduce some land planarians or flat worms, these are the known heartless predator to earthworms.

There was an old lady who swallowed a fly...

Introducing flatworms could be a viable solution, but scientists are extremely averse to introducing yet another new invasive species to take care of the first. It's been done before, and turned out badly almost every time. There are always severe unanticipated consequences.

The best thing we can do now I think try to catch as many as possible of there kind and make it a bait.
