How does the physical presence of ashy mining bee nests compare to infestations of chafer grubs in turf?

The mining bee activity is temporary and related only to reproduction, resulting in unsightly holes but causing no structural damage to the lawn, unlike soil-dwelling beetle larvae like chafer grubs that feed on roots.
