Moles

How to Deter Moles

• If you have a persistent mole problem, the best solution is trapping. Frankly, this is often the only way to get rid of moles. Use a humane trap, and release the moles at least 5 miles from your home in a rural area away from someone else’s garden. See more details below.
• Placing ultrasonic devices or noisemakers such as spinning daisies near the runs are often effective.
• Owning a cat that enjoys walking through your flower beds is a very effective deterrent to rodents.
• Moles are carnivores that make themselves at home in lawns rich in grubs and insects. When their food is seasoned with castor oil, they will go elsewhere for meals. (Wouldn’t you?) Mix up a spray of 3 parts castor oil to 1 part dish detergent; use 4 tablespoons of this concoction in a gallon of water, and soak the tunnels and the entrances.
• Dip an ear of corn in roofing tar and place it in one of their tunnels. Moles hate the smell of tar, and you’ll block their escape.
• Some readers say it works to sprinkle dried blood, tobacco, powdered red pepper, or coffee grounds near tunnel entrances. Remember to re-apply after a rain.
• However, many folk remedies do not control moles, such as placing gum, human air, bleach, ammonia or mothballs near the tunnels. And remember that moles will not eat peanuts or grain; they are insectivores.
• You may have luck using wind power—setting up vibrations in the ground that will bother moles and send them away. Low-tech methods include kids’ pinwheels placed here and there on the lawn, or a homemade thumper: Cut fins in the sides of a bleach bottle and place it on a stick driven into the ground near a mole entrance.
• Finally, there are mole repellents as well as baits though we do not personally use. Bromethalin is sold in the form of a worm-shaped bait; place baits in an active mole run. Correct placement is critical; read and follow all directions provided with the product.

Trapping Moles

No permit is required for trapping. Place traps so that they will be triggered as moles travel in the runs. 

Before placing a trap, make sure the run is active by pressing down with your foot; if the soil is pushed up the next day, the run is still active. 

Straight runs, especially those near the edges of a driveway or sidewalk, are preferred. It the trap does not catch a run in two days, move the trap to a different run.

Prevent Moles

• Check out your soil for the presence of pests; if you have a lot of moles, you may have an oversupply of grubs and bugs. You can try getting rid of the grubs with beneficial nematodes, however, it doesn’t necessary mean the moles will go away; grubs are only part of their diet. 
• If you want to protect specific plants, dig a 2- to 3-foot hole and line the sides and bottom of the hole with wire mesh. Fill the hole with soil and plant.
• Where you are determined to try bulbs, make a small “cage” of ½-inch mesh screen. Place several bulbs inside, root plate down and bury the entire cage at the proper depth. Rodents won’t be able to chew through, but roots and stems can grow out. Note: moles are often blamed for the damaged caused by field mice.
