What Are Armyworms?

Armyworms are small caterpillars that are the larvae of a tiny brown-gray moth. The pests get their name from their tendency to crawl together in large numbers, depleting the food supply in an area. Armyworms usually focus on agricultural crops but in the later months of summer and early fall, the caterpillars and moths will go after any food they can – including your lawn. 

The armyworms can be identified by their original coloring of green with a black head, but then turn brown with white lines on their side after they’ve been munching on grass for about two weeks. 

How to Tell if Your Lawn Has Armyworms

It’s important to stay vigilant this time of year for any unwanted pests. Armyworms are much easier to treat if you catch them early. Check out these tips to stay on top of your lawn and catch any armyworm infestation signs immediately. 

  • Grass Type: Determine if your grass is prone to armyworm infestations. Grass types such as buffalograss, fescue, ryegrass, and bluegrass are more likely to experience armyworms setting up camp. 
  • Brown Patches: Brown patches in your lawn can be an indicator of these pests. Armyworms are fairly visible to the eye so they can also be spotted crawling on your driveway and sidewalk. 
  • Birds: The caterpillars are a great snack for birds. Since the armyworms are most active at night and early morning, you may see an increased number of birds in your yard feasting. This can certainly help lower the number, but won’t be enough to restore your lawn.
