When it comes to a healthy, beautiful lawn, there’s nothing more frustrating than dealing with grubs and moles. These pesky critters may seem small, but they can cause significant damage to your grass, plants, and garden beds if left unchecked. Fortunately, you don’t have to let grubs and moles take over your lawn. With a few smart strategies and preventative measures, you can keep these lawn invaders at bay and maintain a lush, thriving landscape.
At Morales Lawn Care, we specialize in creating and maintaining healthy landscapes that are free of pests. Here’s everything you need to know about deterring grubs and moles from your yard.
Understanding Grubs and Moles
Before we jump into solutions, let’s understand the problem:
- Grubs are the larvae of beetles (like Japanese beetles or June bugs) that feed on grass roots. When grubs damage the roots, it weakens the grass and makes it more susceptible to drought, disease, and other pests.
- Moles, on the other hand, are small mammals that tunnel underground in search of insects (often grubs). While they don’t directly feed on your grass, their tunnels cause extensive damage to lawns and garden beds. They also create mounds that make your lawn look unsightly.
Step 1: Prevent Grubs from Taking Over

Grubs are often the root cause of mole problems, so controlling them is key to keeping moles away. Here’s how to manage grub populations in your yard:
1.1. Apply Beneficial Nematodes
Beneficial nematodes are microscopic organisms that naturally hunt and kill grubs. They’re safe for plants, pets, and people, making them an eco-friendly choice. Apply nematodes in early summer (around June or July) when grubs are most active in their larvae stage.
1.2. Use Organic Grub Control Products
If you want to steer clear of synthetic pesticides, there are organic grub control products available that use natural ingredients like milky spore, which specifically targets grubs. These are slow-acting but can be highly effective over time.
1.3. Promote Healthy Grass Growth
A thick, healthy lawn is naturally more resistant to grub damage. Regular fertilization, aeration, and overseeding can help your grass grow strong and vibrant. Well-established grass has deeper roots, making it harder for grubs to cause lasting damage.
1.4. Timing is Everything
The best time to treat for grubs is in late summer to early fall, when the grubs are still young and feeding on your grass roots. Treating at the right time can reduce the next generation of grubs and, in turn, limit mole activity.

While grubs attract moles, moles can also be deterred with some simple steps. Here’s what you can do:
2.1. Remove Grub Sources
Since moles feast on grubs, reducing the grub population is the first step to keeping moles out. Follow the strategies outlined above to manage grubs effectively. Without their food source, moles will move on in search of a new territory.
2.2. Install Physical Barriers
If moles are a consistent problem, you may want to consider installing a physical barrier like mesh wire or hardware cloth under your soil. These barriers block moles from tunneling through your yard and can be especially useful around gardens or flower beds.
2.3. Use Mole Repellents
There are several natural mole repellents on the market that use ingredients like castor oil, garlic, or hot pepper. These products disrupt moles’ sense of smell, making your yard less attractive to them. Some lawn care professionals can also apply professional-grade repellents that are safe for pets and children but effective at driving moles away.
2.4. Trap Moles Safely
If moles are particularly stubborn, you can use humane traps to catch and relocate them. However, this method requires patience and regular monitoring. Make sure to check local regulations before trapping or relocating moles, as some areas have specific rules about wildlife management.
Step 3: Maintain Lawn and Garden Health
A key part of keeping both grubs and moles at bay is maintaining a healthy lawn. Here’s how you can keep your grass and garden flourishing:
3.1. Aerate Your Lawn
Aerating your lawn helps improve water, nutrient, and oxygen flow to the roots, making it more resilient to pests like grubs. Aeration also breaks up compacted soil, which may discourage moles from burrowing in your lawn.
3.2. Keep Your Lawn Clean
Rake up dead leaves, twigs, and debris regularly. These can provide shelter for both grubs and moles. By maintaining a clean lawn, you reduce the likelihood of these pests finding a safe place to hide.
3.3. Proper Irrigation
Both grubs and moles are attracted to moist environments. While some moisture is necessary for your grass, avoid overwatering your lawn. Aim for deep, infrequent watering to encourage deep-root growth and discourage surface-dwelling pests.
