Moles in Michigan eat grubs and earthworms, not plant roots. The volcano-shaped mounds and raised surface tunnels in your lawn are the side effect of a mole hunting through your soil for protein. To get rid of moles, you reduce the food supply, identify the active tunnels, and place commercial-grade worm bait directly into them — or you let BTR do it. The best timing windows are spring and fall, especially November before the ground freezes.
Moles vs Voles: Different Animals, Different Treatments
Michigan has moles and voles. Both make tunnels in lawns, but they are different mammals with different diets and different treatments. Get the ID right before you treat.
| Trait | Mole | Vole |
|---|---|---|
| Diet | Grubs and earthworms (carnivore) | Plant roots, bark, seeds (herbivore) |
| Sign | Raised tunnels + volcano-shaped mounds | Surface runways in grass; no mounds |
| Damage | Lawn surface only (no plant damage) | Girdles tree bark, eats bulbs and tubers |
| Eyes / ears | Tiny, hidden in fur | Visible, mouse-like |
| Treatment | Worm-bait in active tunnels | Bait stations, snap traps; protect bulbs |
If your plants are being eaten or your tree bark is being stripped at the base, it is voles, not moles. If you have surface mounds and raised tunnels but the plants are untouched, it is moles. Michigan does not have pocket gophers in any meaningful population, so do not chase that diagnosis.
Why Moles Are in Your Yard
A mole is a hunter. It tunnels because that is how it finds the grubs and earthworms it eats. Yards with healthy earthworm populations and active grub populations are prime mole habitat — especially overwatered lawns and lawns near woodlots. Reducing the food source reduces the mole pressure.
The 6-Step Mole Reduction Checklist
- Apply grub control to the lawn. A spring or summer grub treatment reduces the grub population — one of two food sources moles depend on. Earthworms remain (and you want them for soil health), but reducing grubs makes the yard less attractive.
- Reduce overwatering. Soaked soil drives earthworms toward the surface and gives moles easy hunting. Water deeply once a week, not lightly every day.
- Pack down surface tunnels to identify active runs. Use the back of a rake or step on the raised tunnels and flatten them. Active tunnels will be re-raised within 24–48 hours; abandoned tunnels stay flat. Treat only the active ones.
- Place commercial-grade worm bait in active tunnels. Make a small opening in the active tunnel, drop the bait pellet (or worm-shaped bait) inside, then close the opening with soil to keep it dark. Moles encounter the bait while hunting and ingest it.
- Re-check 7–14 days later. If activity continues, place a second round in the new active tunnels.
- Time it right. Spring (April through June) and fall (October through November) are the active windows when moles tunnel close to the surface. November is the most effective single treatment month — right before the ground freezes and the population goes dormant.
Why Mole Home Remedies Fail
The internet recommends castor oil, ultrasonic spikes, chewing gum, mothballs, dryer sheets, vibrating windmills, fox urine, and human hair clippings. None work reliably. Castor oil temporarily annoys moles enough that they detour around it; they do not leave. Ultrasonic spikes are not validated by any peer-reviewed study and field experience does not back them up. Gum and mothballs are ineffective and mothballs are toxic to pets and children. The honest answer: bait placed into active tunnels (or trapping) is the only consistently effective approach.
BTR's Mole Treatment
BTR mole treatment starts at $350 and includes two visits placing two rounds of commercial-grade worm bait into the mole tunnels. Price scales with the number of bait pieces needed (large yards or heavy infestations need more). The treatment carries a 90-day warranty. Spring and fall are the high-effectiveness windows; treatment can be applied year-round but timing it to active tunneling produces the best results.
Mole damage to a lawn is cosmetic — raised tunnels can be rolled back down once moles are gone, and a normal lawn-care program restores the surface. The treatment fixes the mole problem; the lawn fixes itself.
Frequently Asked Questions
When is the best time to treat for moles in Michigan?
Spring (April through June) and fall (October through November) are the active mole windows when moles tunnel close to the surface and bait placement is most effective. November is the strongest single treatment month, just before the ground freezes and the population goes dormant.
Do moles eat plant roots?
No. Moles are carnivores that eat grubs and earthworms. If your plants are being eaten or your bulbs are disappearing, the culprit is voles, not moles. Voles are mouse-like rodents that travel surface runways and eat plant material; moles tunnel underground and never touch plants.
Does castor oil work for moles?
Castor oil temporarily annoys moles enough that they detour around treated areas, but it does not eliminate them. Field results are inconsistent and short-lived. The honest assessment: commercial-grade worm bait placed in active tunnels is far more effective than any repellent product.
Do ultrasonic mole spikes work?
No reliable field evidence supports ultrasonic mole spikes. They are not validated by peer-reviewed study, and BTR's field experience matches the literature — moles ignore them. If a spike worked, the manufacturer would publish controlled-trial data; none do.
How do I know which tunnels are active?
Pack down the raised tunnels using the back of a rake or your foot. Wait 24 to 48 hours. Tunnels that are re-raised in that window are active; tunnels that stay flat are abandoned. Treat only the active ones — this is more efficient than treating every tunnel in the yard.
Will grub control alone get rid of moles?
Partially. Grub control reduces one of two food sources. Earthworms (the other source) remain, so moles may stay if earthworm density is high. Grub control combined with reducing overwatering helps a lot. For an active mole population, professional bait treatment in active tunnels is the most reliable removal method.
How much does BTR mole treatment cost?
BTR mole treatment starts at $350 and includes two visits placing two rounds of commercial-grade worm bait into the mole tunnels. Price scales with how many bait pieces are needed for the property. The treatment carries a 90-day warranty. Spring and fall are the most effective windows.
Have Mole Tunnels in Your Yard?
Free inspection. Two-visit treatment. 90-day warranty. Licensed Michigan applicators.
