Which lawn condition modification can potentially make an area less appealing for future nesting by ashy mining bees?

Answer

Slightly increasing the thatch layer or compaction over winter.

Since these bees prefer bare, well-drained, and relatively undisturbed soil, slightly increasing turf density or compaction during the off-season can make digging slightly more difficult for emerging females next spring.
