Recognizing the Threat of Armyworms

These aren’t your normal pests in the garden. Aggressive caterpillars, fall armyworms can devour an entire lawn almost overnight due to their large feeding population. Their military-inspired name comes from the fact that, in contrast to solitary insects, they attack as a single unit.

Austin Homeowners Find Armyworms Especially Problematic

Armyworms love healthy yards, so lush grass is their favorite thing. Check out more reasons why homeowners dislike these bugs. 

• Lightning-fast devastation. In just 24 to 48 hours, they can totally destroy a lawn.
• Seasons have several generations. New waves emerge every 30 days.
• They have a discriminating taste. Fertilized, well-maintained turf is their favorite snack.
• Stealthy behavior. Usually hiding in the ground during the day and coming out to feed at night.

Identifying an Invasion of Armyworms

The best defense is early detection. Here are some things to look out for.

Physical Attributes

• Different hues: black, brown, or green with recognizable stripes
• Develops into full-sized caterpillars (1.5″) from tiny larvae (1/8″)
• On their heads, look for the distinctive inverted “Y” marking
• Most active after rain and during cooler hours (dawn/dusk)

Indicators of Lawn Damage

Armyworms chew grass blades down to the stems. The following signs may prove that armyworms are eating your yard.

• Uneven brown patches that appear suddenly
• Blades of grass that have been chewed down to the stems
• Places that seem “scalped” instead of just dry
• Bird activity that is unusual (birds eat the caterpillars)

If left alone, an invasion can hurt new grass seeds and leave existing lawns in shambles.

Successful Techniques for Removing Armyworms from Minor Infestations

Manual Removal

If you identify the issue early on, handpicking may offer some short-term respite. Gather any caterpillars that are visible at sunrise or sunset and discard them in soapy water. However, because it’s easy to overlook eggs and newly hatched larvae, this approach rarely fully resolves the issue.

Chemical Treatments

Prevention Should Be Your First Line of Defense

Stop armyworms before they start with the following measures.

• Schedule preventative treatments. Especially crucial in late summer.
• Maintain proper mowing height. Avoid scalping your lawn.
• Implement smart fertilization. Overfed grass attracts more pests.
• Encourage natural predators. Birds, wasps, and beneficial nematodes.
• Regular monitoring. Inspect weekly during peak season.
