How Can I Get Rid of Moles in My Lawn?
Signs of Moles in the Lawn
Moles can cause damage to a landscape, including turfgrass, small annual plants, and paver patios or walkways. They tunnel unseen through the top few inches of soil in search of prey, and leave a trail of damage behind them. In a lawn, the tunnels appear as narrow ridges that may have a small hole here or there where the mole popped its head out. In a lawn with a lot of mole activity, the surface may feel spongy as it is walked upon. These are tell-tale signs of a mole problem.
Eradicating the Moles
Many homeowners think that applying a grub control solution will deter moles. Unfortunately, this rarely seems to work, though you will find lots of pest control companies and people all over the web who tell you this will work. They say killing the food source of moles will send the moles elsewhere, but grubs are not the main food source of moles. While they do eat grubs, the main staple in a mole’s diet is earthworms. Moles also enjoy slugs, snails, centipedes, millipedes, and other juicy insects in your soil that are beneficial for your turfgrass and other landscape plants.
Applying an insecticide that would kill all of the life in your soil would be a setback for your turfgrass and landscape plants, and most insecticides are either acutely toxic to people and pets or they are water contaminates. Crownover Green does not recommend applying insecticides to eradicate moles.
We’ve had many clients who have had moles, and don’t know of any who got rid of the moles by killing bugs. The only proven way to eradicate moles is to kill the moles.
Hiring a Professional
The hassle-free method for eradicating moles is to contact a professional critter control service that will have the expertise to trap the moles. Beware that a general pest control company may offer grub control as the first step. When this method doesn’t eradicate the moles they’ll offer additional services at additional costs. Find a pro that addresses the problem directly.
Do It Yourself (DIY) Options
If you are a DIYer, there are several products available at garden centers. If you really don’t want to kill the moles and are not expecting total eradication, then you could try mole deterrents. There are sonic spikes and castor oil repellents that act as deterrents. You may need to use both deterrents indefinitely and reapply repellents regularly to keep your lawn inhospitable for the moles.
Other options include traps, gassers, and poisonous baits to kill the moles. Our recommendation is to use a trap, because it is the only method that provides verifiable proof when you got one.
Whatever DIY option you might choose, follow the label instructions closely to get results. Moles become very active in late winter or early spring as the ground becomes soft. Spring is also mating season for moles so spring is a good time to get them under control.
