Especially if it is Greylings, the Wards seem to wipe them out pretty quick. Wards are definitely worth having even in single-player.

Wards don't do that. They prevent other players from opening stuff or constructing/deconstructing. They don't offer damage protection. They don't do damage. They pulse and chime if any object in the wards radius is damaged (even for 0 damage). They provide the standard no spawn zone.
