Several insects can damage turfgrass by feeding on roots, stems, crowns, or grass blades. In Utah’s warm summer climate, turf insects often become more active when lawns are already stressed by heat, drought, or soil compaction. Early detection and proper treatment are important to prevent long-term lawn damage.

Common Turf Insects Found in Utah Lawns

Billbugs
Billbugs are one of the most common turf pests in Utah. Adult beetles lay eggs in grass stems, and the larvae feed within the crown and roots of turfgrass. Damage often appears as irregular brown patches that resemble drought stress.

White Grubs (Beetle Larvae)
Grubs feed on turf roots beneath the soil surface, weakening the lawn and causing areas of grass to pull up easily. Severe infestations can lead to widespread thinning and may attract animals such as raccoons or skunks digging for food.

Chinch Bugs
Chinch bugs feed by sucking plant juices from grass blades. Their feeding causes expanding yellow or brown patches that often appear during hot, dry weather.

Sod Webworms
Sod webworm larvae feed on grass blades at night, creating small brown patches and thinning turf. You may notice small moths flying just above the lawn at dusk.

Armyworms
Armyworms can cause rapid turf damage by feeding on grass blades in large numbers. Outbreaks may occur during warm weather and can quickly thin large areas of turf.

Cutworms
Cutworms feed at night and chew through grass blades near the soil surface, often leaving small circular patches of damaged turf.

Cranberry Girdlers
Cranberry girdler larvae feed on grass stems and crowns near the soil surface. This damage can cause turf to thin and become patchy, especially in lawns with heavy thatch buildup.

Leatherjackets (Crane Fly Larvae)
Leatherjackets feed on turf roots and stems, which can cause thinning turf and irregular dead patches.

Grasshoppers
Although not always a primary turf pest, grasshoppers may feed on grass blades and ornamental plants during outbreak years in Utah.

Signs of Turf Insect Damage

Homeowners may notice:

• Irregular brown or thinning patches

• Turf that pulls up easily from the soil

• Increased bird or animal activity digging in the lawn

• Grass blades that appear chewed or damaged

• Turf that does not respond to watering or fertilization

Because insect damage can often resemble drought stress or disease, proper identification is important before treatment.

🌱 Rooted in Care — From Soil to Sprout

What Is Happening

Yellow grass often indicates that turf is struggling to produce chlorophyll, the pigment responsible for healthy green color and photosynthesis.

Why It Happens in Utah

Many lawns along the Wasatch Front grow in naturally alkaline soils, which can prevent grass from properly absorbing key micronutrients such as iron, manganese, and zinc. Even when nutrients are present in the soil, the plant may not be able to access them.

Other common causes include:

• nutrient imbalances
• soil compaction limiting root growth
• irrigation problems
• turf insects or disease

What Homeowners Notice

• pale or yellow grass
• yellowing between leaf veins
• slow growth or thinning turf

The Spectrum Soil Solutions Difference

Many companies simply apply high nitrogen fertilizer to quickly force green color.

At Spectrum Soil Solutions, we take a different approach.

Our trained technicians evaluate the lawn conditions and focus on diagnosing the true cause of the problem rather than masking the symptoms.

We may recommend:

✔ micronutrient applications such as iron
✔ soil conditioners that improve nutrient availability
✔ aeration to improve soil oxygen and root growth
✔ soil testing to determine nutrient deficiencies

By correcting the underlying soil conditions, we help lawns return to a healthy, natural green color that lasts longer.

What Is Happening

Brown patches occur when grass becomes stressed or damaged and begins to die back.

Why It Happens

Common causes include:

• turf insects such as billbugs, chinch bugs, or grubs
• drought and heat stress
• overwatering or poor drainage
• compacted soil preventing roots from accessing water
• disease development under certain conditions

What Homeowners Notice

• irregular brown or thinning patches
• turf that does not recover with watering
• grass pulling up easily from the soil

The Spectrum Soil Solutions Difference

Instead of immediately applying treatments, our team takes time to investigate the root cause of the damage.

Our technicians are trained to evaluate:

✔ soil conditions
✔ insect activity
✔ irrigation coverage
✔ nutrient levels

If needed, we can perform soil testing and diagnostic evaluations to determine exactly what the lawn needs.

Our programs focus on:

✔ improving soil health
✔ strengthening root systems
✔ targeted pest treatments when necessary

This approach helps prevent the problem from returning.

What Is Happening

Thin lawns develop when grass plants cannot establish strong root systems or when turf density declines over time.

Why It Happens

Common causes include:

• compacted soil limiting root growth
• nutrient deficiencies in alkaline soil
• turf insect damage
• irrigation problems
• heavy thatch buildup

What Homeowners Notice

• patchy or uneven turf
• bare soil areas
• grass struggling to fill in

The Spectrum Soil Solutions Difference

Many lawn companies attempt to fix thin turf by simply applying more fertilizer.

Our team focuses on improving the soil environment that supports healthy turf growth.

Our approach may include:

✔ soil testing and nutrient analysis
✔ aeration to relieve soil compaction
✔ soil conditioning treatments
✔ balanced fertilization designed for Utah soils

By improving soil structure and root health, lawns naturally grow thicker and more resilient.

What Is Happening

Utah’s hot summers place significant stress on turfgrass.

Why It Happens

• high temperatures and drought conditions
• shallow root systems
• poor water infiltration
• increased insect activity

What Homeowners Notice

• lawns turning brown during heat waves
• turf becoming thin or stressed
• slow recovery after mowing

The Spectrum Soil Solutions Difference

Rather than forcing excessive growth with high nitrogen fertilizers, we focus on building deeper roots and stronger soil conditions.

Our summer lawn care strategies include:

✔ balanced nutrient applications
✔ soil conditioning treatments
✔ aeration to improve water infiltration
✔ targeted pest monitoring

This helps lawns remain more drought-resilient and better adapted to Utah’s climate.

What Is Happening

Water running off the lawn instead of soaking in usually indicates compacted soil.

Why It Happens

• heavy clay soils common in Utah
• repeated foot traffic
• mowing equipment
• lack of aeration over time

What Homeowners Notice

• water pooling on the lawn
• runoff onto sidewalks or driveways
• dry spots despite watering

The Spectrum Soil Solutions Difference

Our technicians evaluate soil structure and irrigation performance before recommending solutions.

We may implement:

✔ core aeration to relieve compaction
✔ liquid aeration treatments
✔ soil conditioners that improve water infiltration

By improving soil structure, we help water reach the root zone where it benefits the lawn most

What Is Happening

Weeds often invade lawns when turf becomes weak or thin.

Why It Happens

• nutrient imbalances
• thin turf coverage
• exposed soil areas
• lack of weed prevention
