One mole can dig up to 100 feet of tunnel per day. In Marshalltown’s rich, loamy soil, moles find everything they need — dense earthworm populations, easy digging, and plenty of space to expand. What they leave behind is a lawn that looks like something exploded underneath it: raised ridges running across the yard, volcano-shaped mounds pushed up through the turf, and root systems undermined by a network of tunnels. Miller Pest Solutions removes moles with proven methods — not repellents that don’t work.

Signs of Mole Activity in Your Yard

  • Surface tunnels (runways) — Raised ridges running in irregular patterns across the lawn, just below the surface
  • Volcano-shaped mounds — Cone-shaped dirt piles pushed up from below as moles excavate deeper tunnels
  • Soft, spongy ground — Walking across the lawn feels unstable where tunnel networks run beneath
  • Dead grass — Tunneling severs grass roots, causing brown stripes or patches following tunnel lines
  • Increased activity in spring and fall — Moles work closest to the surface when soil is moist and earthworms are near the top

Why Moles Are Common in Marshalltown

Iowa’s soil is some of the richest agricultural ground in the world — and that same quality that makes it great for farming makes it ideal mole habitat. Marshalltown’s loamy, well-aerated soil supports enormous earthworm populations, which is exactly what moles are after. Moles are insectivores — they eat grubs and earthworms exclusively. They don’t damage plants or eat roots. The destruction to your lawn is entirely structural, caused by the tunneling itself.

Moles are solitary, so one animal can cover a surprisingly large area. That network of tunnels crisscrossing your yard? Probably one or two moles at most. They’re highly territorial and will aggressively defend their tunnel systems from other moles.

Moist soil conditions after rain or irrigation bring earthworms close to the surface, which in turn brings moles working in shallow surface tunnels — the ones that do the most visible lawn damage.

Our Mole Control Process

Miller Pest Solutions uses trapping and baiting methods — the approaches with documented results. Repellents, vibration stakes, castor oil granules — these don’t reliably control moles, and we won’t waste your money on them.

  • Tunnel assessment — We identify active tunnels versus abandoned ones. Trapping an inactive tunnel is wasted effort. We know how to tell the difference.
  • Trapping — Professional-grade mole traps set in confirmed active runways and main travel corridors. This is highly effective when placed correctly.
  • Baiting — Worm-shaped mole bait placed in active tunnels. Moles consume it as they travel, providing effective control without extensive surface disruption.
  • Follow-up monitoring — We check and reset traps, confirm activity levels, and continue until mole activity ceases.

Mole control isn’t a one-visit fix in most cases. We’re upfront about that. Active tunnels need to be monitored and worked consistently until the animal is removed.
