I don't recomend trying to kill the invisible enemies. Each time you kill one, another will spawn until there will be too many to handle. If this happens, use a bonfire to reset them.

You can distract the guardians by hitting the trees with faces on. The sound will alert the guardians but you can sneak past them whilst they investigate.
