Earthworm leave small muddy piles called worm castings on the lawn surface.

- No large hole in the center
Good news: Worms are beneficial and improve soil health.
2. Ants 🐜
Ant colonies can create small dirt mounds.
Signs
- Tiny volcano-shaped piles
- Very small hole in the center
- Lots of ants nearby
3. Mole activity 🐾
Mole can push soil up while tunneling.
Signs
- Larger piles of soil
- Raised tunnels or ridges across the lawn
4. Ground-nesting bees
Mining Bee sometimes make little dirt piles.
Signs
- Small round hole
- Bees flying close to the ground in spring
✅ What you can do
- Earthworms: Just rake or spread the mud when it dries. They’re actually good for the lawn.
- Ants: Use ant bait or lightly flood the mound with water.
- Moles: Trapping or deterrents may be needed.
- Bees: Usually harmless and temporary.
