How to Check for Armyworms in Sod and Turfgrass
A lush, healthy lawn is a source of pride for many homeowners, but it can quickly become a victim to common pests like armyworms. These voracious caterpillars can cause significant damage to sod and turfgrass if left unchecked, turning vibrant green spaces into brown, patchy areas almost overnight.
At Specter Pest Control, we frequently assist homeowners in spotting early signs of armyworm infestations and implementing effective control measures. Knowing what to look for and when to act can save your lawn and keep your outdoor spaces beautiful throughout the growing season.
What Are Armyworms?
Armyworms are the larvae of certain moth species that feed on grass, crops, and other vegetation. Their name comes from their behavior of moving in large groups—like an army—consuming everything in their path.
These pests thrive during warm months, especially after rainy periods, and can rapidly multiply, causing extensive damage to lawns, sod farms, and turfgrass areas.
Signs of Armyworm Damage in Your Lawn
Detecting armyworm activity early is key to minimizing damage. Here are the signs to watch for:
- Irregular brown patches: Armyworms chew grass blades near the ground, leading to discolored patches that spread quickly.
- Visible caterpillars: Armyworms vary in color but are generally green, brown, or black with stripes running lengthwise. Look for them during dusk or early morning.
- Chewed or ragged grass blades: Grass may appear shredded or cut unevenly.
- Frass (caterpillar droppings): Small black pellets found in the turfgrass can indicate active feeding.
- Sudden lawn thinning: Large groups feeding simultaneously can strip the turfgrass, leaving bare soil.
Regularly inspecting your lawn, especially during the peak seasons, helps catch infestations before they become severe.
How to Check for Armyworms in Sod and Turfgrass
Performing a simple check is easy and effective:
- Use the ‘beat cloth’ method: Place a white cloth or sheet on the grass and shake or tap nearby turf. Armyworms will fall onto the cloth, making them easier to spot.
- Inspect in the early morning or late evening: Armyworms are more active during cooler parts of the day.
- Look closely at the base of grass blades and soil surface: Caterpillars often hide in these areas to avoid heat and predators.
- Check the edges of damaged patches: The highest concentration of armyworms tends to be along the advancing edge of damaged turf.
If you find signs of armyworms, acting quickly is essential to prevent widespread damage.
