Pest Facts: Moles

When moles damage lawns, they become of great interest to homeowners.  Understanding moles are key to controlling them.  Listed below are mole facts regarding the habits, diet, and control of moles in the lawn and landscape.

General Information

    • Adult moles are approximately 5-7 in length, have a hairless, pointed snout, and weigh about three to five ounces.  They have paddle-shaped feet, suitable for digging in all types of soil.
    • Moles may appear to be blind.  Their eyes are covered by fur.
    • The gestation period of moles is approximately 42 days.
    • A female mole produces 2-6 young per litter in the spring.
    • The mole’s den is located 12 to 18 inches below the surface and consists of irregular chambers about the size of a quart jar.  They construct both deep and shallow tunnels.  The tunnels seen at the surface are only part of a connected tunnel system.
Moles - Paddle-like Feet
Moles have paddle-like feet with large claws, which are suitable for digging in all soil types.

Mole Habits

  • Moles don’t hibernate. In the winter, they go deeper when the ground is frozen. In the Cincinnati area, the ground is not frozen for most of the winter.
  • Moles can enter the property throughout the year, even after the property has been mole-free for some time.
  • Moles do not create “holes.” Instead, construct tunnels and mounds in the yard and landscape, causing lawn damage by pushing up the soil.
  • Moles mate in the spring. Employing mole control in the winter is a great idea because if the mole dies in the winter, it won’t mate in the spring. According to our experience and research, dead moles cannot reproduce.
  • Moles are active throughout the year.  Mole activity near the surface is less prominent during when the ground is frozen at the surface or during periods of extreme cold, heat, or drought. Moles are more active near the surface after rainfall or watering.
  • Moles are solitary creatures that come together only to breed.  After they leave the den, they spend their lives alone and are very competitive.
  • Moles rarely come to the surface.  When they do, it is usually by accident, as they prefer to stay beneath the surface, unexposed to the elements.

    Underrgound Mole Tunnel
    Moles create tunnels underground, about 1.5-2 inches in diameter. Some tunnels are deeper, while others are closer to the surface, where they push up the soil, causing frustration for homeowners.

Mole Diet

  • Moles are “insectivores,” not rodents. However, while they eat insects (such as ants and grubs), their main diet is earthworms.
  • Moles primarily eat earthworms. Moles are also known to eat white grubs and other insects, but the vast majority of their diet consists of juicy, delicious earthworms.
  • Moles rarely consume roots, bulbs, and other plant material.  Rodent such as voles and deer mice are usually the culprit when damaging plants.
  • Moles consume 70 to 100 percent of their weight each day.  They need that much food to produce energy since they spend ample time burrowing beneath the surface.

Controlling Moles in the Lawn and Landscape

Mole Bait in Active Tunnel
Not all mole baits are effective in controlling moles. Effective mole bait is in the shape of the mole’s natural food source – the earthworm. Poisoned “peanuts” and other grain-based bait is not effective in controlling moles.
    • The key to controlling moles is to identify active mole tunnels. Moles create both active (tunnels they use over and over again) and probing (tunnels they create and rarely re-enter) tunnels throughout the yard.
    • Before employing mole control, first stomp down all the mole tunnels. Check the tunnels after a couple of days to see which tunnels have popped back up. Then you will know which tunnels are active.
    • The best methods of mole control is trapping and baiting.  When baiting, use only bait that mimics the natural food source of moles – the earthworm.  The active ingredient bromethalin, which is effective.
    • Electronic devices placed in the lawn have been proven ineffective in controlling moles. Trapping and only certain baiting products/methods should be used for controlling moles.
    • Repellants are ineffective against controlling moles.

Damage Caused By Moles

Mole Damage - Mounds
Moles cause damage to lawns by creating mounds and tunnels
  • Moles live almost underground, creating a vast network of interconnecting tunnels. While much of their tunnel system is well below the surface, they frequently create tunnels just below the surface where they cause visible damage to the lawn and landscape.
  • If you have holes in your lawn and landscape, the offender is typically a rodent such as a groundhog (larger holes), chipmunk, mouse or vole.  Moles do not create holes that expose them to the elements above ground.
  • Mole mounds are formed when moles push up soil to the surface from underground runways.  When moles tunnel deeper under the surface, they excavate the tunnels by pushing the dirt up to the surface, creating tunnels so they can move about more easily.

Mole Damage In Lawns: What to Look For

Many people spend significant time and money beautifying their lawns, working hard to showcase their beautiful, green, healthy turf. Then, they wake up one morning, coffee in hand, and peer out the window. To their dismay, they freak out as they see their lawn torn up, dropping their java on their beautiful carpet. Their turf has been under attack, unraveled like a cheap sweater.  

Hello. I’m Paul, and I am here to help you. Today, I will help you avoid making mountains out of molehills. As the Boss Hogg of Flying Pig Pest Control, I want to pass on some valuable information to help you identify what is tearing up your yard.  

The mounds and tunnels may have appeared overnight. It can take only a few hours for this damage to occur. It often happens so fast that the unsuspecting homeowner has no clue that the invasion is coming.  

The culprit: moles. Or maybe just one mole. Maybe two or three or more. One mole, however, can create hundreds of feet of tunnels in just one day. With its paddle-shaped feet and digging claws, the mole can tunnel even through the densest clay. When the mole is close to the surface, it pushes up the ground, creating raised tunnels. When the mole burrows deeper, it may excavate the tunnels by depositing dirt on the surface, forming mounds.  


We often get calls from frustrated homeowners who see what they believe to be moles. Some correctly identify mole damage, while others do not. Need a diagnosis? Here is your identification guide.

Mounds and Tunnels

First, understand that moles create only tunnels and mounds. They do not create “holes.” Therefore, there is no such thing as a “holey-moley.”

Mole Mound
Moles create mounds by excavating soil.

Moles that are burrowing deeper below the surface cannot push up mounds, so they excavate the soil by pushing up dirt at a 45 degree angle.  When they are just beneath the surface, they form tunnels as they travel.

Now here are some examples of what are not moles:

We often get calls from homeowners saying that moles have torn through their mulch, creating tunnels throughout the landscape, and pushing up the soil and the mulch. In most cases, this is moles. However, when someone calls and says that moles have invaded their mulch, creating holes everywhere, it is something entirely different. Sometimes people mistake holes from chipmunks and other critters as moles. To learn more about what may be causing the holes, see this article by Purdue University.

Holes in landscape bed
Holes created in landscape beds are often caused by critters such as squirrels and raccoons

One homeowner saw chimney-like crawfish mounds in his yard. Crawfish can be found in portions of lawns that are essentially a “wetland” throughout the year, usually near a pond or other water source.

Crawfish create mounds, but they are unlike mole mounds. Note the hole in the top of the chimney-like mound.

Moles can be controlled by trapping or baiting. Some traps are more effective than others, and the same applies to mole bait. Some baits are completely ineffective, while others, when properly applied, achieve great results. If you live in the Greater Cincinnati, Ohio area, we can help!
