Mole Control Methods — How Professional Mole Trapping Works

Mole control requires different approaches than gopher control because moles behave differently — they are insectivores rather than plant feeders, they create different tunnel systems, and they respond differently to various control methods. Professional trapping is the most reliable approach for resolving mole infestations, but it requires identifying the right tunnel types and setting traps correctly to be effective.

Understanding Mole Tunnel Systems

Moles create two types of tunnels that serve different purposes. Surface tunnels — the raised ridges visible across lawn surfaces — are shallow feeding runs used to hunt earthworms near the soil surface. These tunnels are often used only once or a few times before the mole moves on to a new area. Deep tunnels run 6-24 inches below the surface and serve as the mole's primary travel corridors between feeding areas and the nest. These deeper tunnels are used repeatedly and are the correct location for professional traps.

Setting traps in surface ridges — the most visible sign of mole activity — is a common DIY mistake. Surface ridges are feeding runs that may not be reused. Setting traps in the deep primary tunnels, which require probing to locate, produces far better results because the mole travels these corridors consistently.

Professional Trapping Process

Professional mole trapping begins with correctly identifying active primary tunnels. The technician probes the soil to locate deeper runs, then collapses a small section of the tunnel and marks it. Tunnels that are repaired by the mole within 24-48 hours are confirmed as active primary corridors — the mole is traveling that section regularly. Traps are then set in confirmed active primary tunnels and checked on return visits.

Multiple trap placements are typically needed for a complete mole infestation. A property with extensive tunnel networks may require several trap sets and multiple visits to achieve full resolution. The process is thorough but methodical — each confirmed active tunnel is addressed systematically.

Why Other Methods Fall Short

Repellent products — castor oil granules and sprays are heavily marketed for mole control. Research and field experience consistently show limited effectiveness. Moles may avoid treated areas temporarily but typically return once the repellent disperses, and they often simply reroute to adjacent untreated areas rather than leaving the property.

Ultrasonic devices have no reliable evidence of effectiveness for mole control. Moles that have established tunnel systems in productive earthworm areas are not deterred by vibration or sound devices placed at the surface.

Flooding tunnels does not reliably remove moles. Moles swim competently and will simply retreat to deeper, drier tunnel sections during flooding, returning when conditions normalize.

Grub control treatments — reducing white grub populations in the lawn — may reduce one component of the mole's food supply but does not address earthworms, which are the primary food source. Grub reduction alone rarely resolves mole infestations in earthworm-rich soils.

What to Expect from Professional Service

Professional mole control typically requires multiple visits over one to three weeks. The first visit establishes trap locations in confirmed active tunnels. Return visits check results, reset traps, and address any remaining activity. When no new tunnel activity is observed following the last trap check, the job is considered complete. Mole control includes the same 60-day guarantee as our gopher service.
