When you invest time and money into maintaining a beautiful lawn in California or Arizona, the last thing you want is for pests to ruin your hard work. From grubs to chinch bugs, these unwelcome invaders can wreak havoc on your turf, turning a lush lawn into an unsightly patchwork of brown and dying grass. In California, especially with its diverse climate zones, pests can vary in types and behaviors, making it essential for homeowners to stay proactive about lawn care. As a trusted provider of premium sod for California and Arizona, West Coast Turf is here to help you identify and combat the most common pests that could be damaging your lawn.

1. Grubs: The Root Destroyers

Grubs, the larvae of beetles like the Japanese beetle and the June bug, are one of the most common and damaging pests for California lawns. These white, C-shaped larvae feast on the roots of your grass, disrupting its ability to absorb water and nutrients. As they burrow into the soil, they can cause widespread damage that often shows up as large, irregular brown patches in your lawn.

Signs of grub damage:

• Brown, patchy areas of grass that pull up easily from the soil.
• Small dead patches that seem to spread quickly.
• A lawn that feels spongy underfoot due to the roots being eaten away.

Grubs are often most active during the summer and early fall, so it’s important to take preventive measures during these times. If you notice the signs of a grub infestation, act quickly to minimize damage.

How to protect your lawn:

• Preventative treatments like granular insecticides or natural alternatives such as nematodes can help control grubs before they cause damage.
• Aerating your lawn helps improve soil health and root systems, making it less susceptible to grub damage.
• If you already have grubs, apply treatments in the early summer, when they’re in their larval stage.

2. Chinch Bugs: Small but Mighty

Chinch bugs are another common pest found in both California and Arizona lawns. These tiny, reddish-black insects suck the sap from grass blades, causing the grass to wilt and die. Chinch bugs prefer hot, dry conditions, which makes them especially problematic during California’s long summer months.

Signs of chinch bug damage:

• Irregular patches of yellowing or browning grass, often in sunny or drought-prone areas.
• Turf that feels spongy or soft when stepped on.
• Grass that looks dry despite regular watering.

Chinch bugs are particularly harmful to cool-season grasses, such as fescue or Kentucky bluegrass, which are commonly found in lawns throughout California. Their feeding weakens the grass, making it vulnerable to further stress from heat and drought.

How to protect your lawn:

• Apply insecticides targeted specifically for chinch bugs. Make sure to follow the application instructions carefully for the best results.
• Water your lawn deeply but infrequently to encourage deep root growth, which helps the grass better withstand pests like chinch bugs.
• Consider reseeding or replacing sod in areas heavily damaged by chinch bugs to restore your lawn.

3. Sod Webworms: Moth Larvae that Ruin Your Turf

Sod webworms are larvae of small moths that live beneath the surface of the turf. These larvae feed on grass blades, causing patches of dead, brown grass that can spread quickly if not controlled. Sod webworms are especially active during the warmer months and can severely damage lawns that are already stressed by heat or drought.

Signs of sod webworm damage:

• Small, circular patches of dead or dying grass.
• The presence of small moths flying near the turf, especially in the evening.
• Increased activity from birds or other animals searching for the larvae.

How to protect your lawn:

• Use insecticidal treatments specifically designed for sod webworms. Applying treatments in the late afternoon or early evening can help target the larvae.
• Maintain a healthy lawn by watering properly and aerating regularly to reduce compaction.
• Encourage natural predators, like birds and beneficial insects, to help manage the population of sod webworms.

4. Ants: More than Just a Nuisance

While ants might seem harmless at first glance, certain species, such as Argentine ants or fire ants, can cause significant damage to your lawn. These ants create nests and mounds in your grass, disturbing the root system and soil structure. Fire ants, in particular, can sting, which makes them a health hazard for pets and children.

Signs of ant infestation:

• Mounds of dirt or raised areas in the grass.
• Dry, patchy areas where ants have disturbed the soil.
• A sudden increase in the number of ants in your lawn.

How to protect your lawn:

• Use targeted ant baits or insecticides to treat visible mounds. Be sure to follow the manufacturer’s instructions for safe and effective treatment.
• Keep your lawn properly watered to discourage ants from nesting in dry areas.
• Reseed or replace sod in areas with extensive ant damage.

5. Lace Bugs: A Hidden Threat to Your Grass

Lace bugs are another common pest in California lawns, particularly in areas with hot, dry summers. These tiny insects feed on the undersides of grass leaves, causing small yellow spots and a general decline in turf health. While lace bugs don’t always cause immediate, catastrophic damage, their feeding can weaken grass and make it more susceptible to other issues like drought stress and disease.

Signs of lace bug damage:

• Yellow or spotted patches on grass blades, often appearing on the lower side of leaves.
• General decline in the overall health of the turf, especially in stressed areas.
• Grass that seems to be wilting or drying out despite proper care.

How to protect your lawn:

• Use insecticidal soap or neem oil to target lace bugs and prevent them from spreading.
• Regularly check the underside of grass blades for signs of lace bug infestation.
• Fertilize and water your lawn to keep it healthy and more resistant to pest damage.
