A mole can dig up to 100 feet of tunnel in a single day. One mole working through a New Virginia lawn for a few weeks can turn a smooth, well-kept yard into a network of raised ridges, soft spongy patches, and cone-shaped mounds that look like a small volcanic field. Moles are solitary, they’re almost never seen above ground, and they’re relentlessly driven by the hunt for grubs and earthworms. Getting rid of them takes more than a box of repellent stakes from the hardware store. Miller Pest Solutions has been dealing with mole problems across Iowa for years and uses methods that actually work.

Signs of a Mole Infestation

  • Raised surface tunnels — The most recognizable mole sign. These ridges of pushed-up soil crisscross the lawn just below the surface, creating soft, raised pathways that collapse underfoot. Active runs will spring back slightly when pressed; abandoned ones are firm and flattened.
  • Volcano-shaped mounds — Unlike gopher mounds (which are fan-shaped), mole mounds are symmetrical cones or rounded piles of pushed-up soil with the hole plugged in the center. These mark deeper tunnel construction.
  • Spongy, soft ground — Walking over mole tunnel networks feels mushy or springy. The turf feels undermined because it is — the tunnel just below is hollow.
  • Dead turf along tunnel lines — Mole tunneling severs grass roots and exposes them to drying air. You’ll often see yellowing or dying grass strips directly above active runs.
  • New activity after rain — Earthworms and grubs become more active near the surface after rain, and moles follow. Fresh mounding and new tunnel ridges appearing after wet weather is a reliable activity indicator.

Why Moles Are Common in New Virginia

Iowa’s soils are among the most productive in the world — deep, rich, and full of organic matter. That same quality that makes Iowa farmland valuable is exactly what supports massive earthworm populations, and earthworms are the primary food source for moles. New Virginia’s loamy soils and maintained lawns are essentially a well-stocked buffet. Irrigation, rainfall, and organic lawn care practices that support healthy turf also support the earthworm populations that bring moles in. Moles are solitary — you rarely have more than one or two per yard — but one mole causes enough damage to make it feel like more. There’s no such thing as a “mole-proof” lawn when the soil conditions are this favorable.

Our Mole Control Process

Miller Pest Solutions uses trapping and baiting to eliminate moles. These are the methods with the strongest evidence behind them — not repellents, not vibration devices, not castor oil treatments. Those products are heavily marketed and consistently underperform.

Trapping involves identifying active tunnel runs (not all tunnels are actively used daily) and placing professional-grade traps in the right positions. This requires knowing mole behavior — which tunnel sections are main thoroughfares versus exploratory runs — and checking traps on the right schedule. It’s skilled work, not just dropping a trap in a hole.

Baiting uses worm-shaped bait products placed directly into active tunnels. Moles investigate new objects in their tunnels and consume the bait. Baiting can be effective as a standalone approach or in combination with trapping depending on the situation and time of year.

We identify active areas, treat them systematically, and follow up to confirm the moles are gone. New moles can move into territory vacated by eliminated ones, so follow-up assessment is part of the process.
