Stealthy moves happen before ritual spells. So, catching them is very difficult. You actually have to target the spell where you expect them to sneak to rather than where they are.

You can try to anticipate where they are going to strike next and set ambushes, which can consume a lot of resources. Also, you can patrol choke points. Or, you can just wait for the raider to move and retake the province.

There are globals like Wrath of God and, I believe, Wild Hunt, that will catch sneaking commanders. Though, the latter would only work on priests.

If you are a blood nation, Looming Hell is pretty effective if your opponent is sneaking troops along with his commanders. It's great to see a large enemy force wiped out when one of the recruits takes out the leader.
