Mole Lawn Damage Repair

How to Fix Mole Damage to Your Southern California Lawn

Mole tunneling creates raised ridges, collapsed surface areas, uneven terrain, and dead grass patches. These can all be repaired — but as with gopher damage, eliminate the mole first. Repairing mole damage with an active mole will produce new damage within days.

Step 1 — Confirm the Mole Is Gone

Wait until no new surface ridges or mole mounds have appeared for at least 2-3 weeks within your 60-day guarantee period before starting significant lawn repairs. New activity within the guarantee period means we return at no charge — call 909-599-4711 before investing in repairs.

Step 2 — Flatten Surface Ridges

Mole surface feeding tunnels create raised ridges that can be pressed flat:

Use a lawn roller or simply walk firmly along the ridges

Water the area first to soften soil and make flattening easier

For ridges that have dried and hardened, soak thoroughly before rolling

Check for voids beneath flattened ridges — if hollow, fill before rolling

Step 3 — Address Collapsed Tunnel Areas

Deep primary tunnel collapses leave soft, sunken areas:

Probe to identify extent of collapse

Fill with topsoil and tamp firmly

Water thoroughly to help soil settle

Repeat filling as soil continues to settle over several weeks

Step 4 — Reseed Dead Grass

Mole tunnels dry out root zones, killing grass in tunnel patterns. Repair dead areas:

Remove dead grass and loosen soil

Apply grass seed matched to your existing lawn type

Topdress lightly and water daily until established

For large dead areas, sod replacement is faster than seeding

Timing Lawn Repairs in Southern California

Fall (October-November) and spring (March-April) are the best times for lawn repair and reseeding in Southern California. Avoid major lawn renovation during summer heat or during peak mole season — wait until mole activity has stopped under your guarantee before investing in repairs.
