Quick answer
Moles eat earthworms and insects, not grass roots. Their tunnels lift the turf and dry it out. Trapping is the most reliable control; treating for grubs alone often doesn't stop them.
Signs of Moles
- Raised ridges across the lawn
- Volcano-shaped soil mounds
- Spongy areas when you walk
What Actually Helps
Because moles mainly eat earthworms, killing grubs rarely makes them leave. Mole traps placed in active tunnels are the most dependable option. Check activity by stepping down a tunnel and seeing if it's raised again the next day.
Repairing the Lawn
Press tunnels back down, rake out mounds, and water. Bermuda fills in quickly in summer; topdress and overseed thin spots if needed.
