How to get rid of Moles in the Garden
Problem: You see raised ridges throughout the garden & yard. The ridges are usually about 3-5 inches wide.
The bad news: your garden or lawn has moles.
The good news: It is possible to get rid of moles in the yard or garden, but you'll need both patience and persistence.
You'll be more successful in getting rid of moles, if you understand a little about them first. Moles are small rodents that live underground. They're around 6" long, have velvety fur, and very small eyes (since they live underground).
Moles don't eat the roots of your plants. They eat grubs and earthworms in the soil. But their tunneling does disturb the root systems of your plants. And worse, other rodents (like mice or voles) who do eat roots will sometimes move into the tunnels.
Key to getting rid of moles:
More than likely, if you have moles, you have a beetle grub problem. Remove the source of food (the beetle grubs) and the moles will more than likely move onto more plentiful hunting grounds.
Note: Treating for the beetle grubs is important because, left untreated the grubs will mature into beetles (Japanese beetles, June beetles, etc.) that will infest your garden. Also, beetle grubs can kill sections of your lawn.
Gardening tip: When you see tunnels around your plants, you will want to immediately pat down the soil around the plants (filling in the tunnel) and water the plant heavily. This will help the plant recover.
How to Get Rid of Moles Organically:
Option 1: Apply milky disease spore to the affected area (kills the grubs), but this takes several applications over a season, and patience. It won't get rid of them overnight. If you're diligent in applying the milky disease spore, you likely won't see results until the next gardening season.
Option 2: Build a barrier about 2 feet deep and 6" wide, buried in the soil around the area you want to protect. (Fill the barrier with rocks or similar coarse, hard material.) The moles won't try to burrow through the barrier.
Note: this only works if the area you're protecting is already mole-free.
Option 3: Place traps in the active tunnels. You can purchase traps at most hardware or garden supply stores. To locate an active tunnel, first step on the tunnel and lightly pack it down. Then check it over the next few days. If the tunnel is raised again, it is an actively used tunnel.
Besides being a little gross (the trap skewers the mole), the trouble with this plan lies in that it doesn't treat the real problem (the grub infestation).
Option 4: There are repellants on the market as well that may work, Caster oil's also been known to repel moles. However, what usually happens when using repellants, is that you end up driving the moles to another section of the garden.
How to Get Rid of Moles Non-Organically:
- You can try poison baits, but they don't normally work well. Plus, do you really want to put poison in the soil that produces the food you eat?
