Small Dirt Mounds in NC Yard: Likely Tiger Beetle Larvae, Not Wasps

Coffee-cup-sized mounds with pencil-width holes in central NC, reappearing daily, match tiger beetle larvae behavior. These beneficial predators dig vertical burrows, wait at the entrance for prey, and retreat instantly when disturbed. They don't damage grass.

Confirmation and Coexistence

Larvae are metallic, fast, and shy. No control needed — they eat pests. If mounds annoy, lightly tamp them; larvae rebuild. They're a sign of healthy, biodiverse soil.
