Armyworm caterpillars consume more vegetation in the last four days of their caterpillar phase than the rest of their life combined. Treating these pests as quickly as possible when you spot them can save you from most of the damage that could occur. Method 1.

  • Aug 13, 2014Granular insecticides are generally less successful with army worms. Lastly, we suggest that you leave your lawn alone for at least three days without mowing or watering. This will give the insecticide a chance to do its work.

  • Dec 01, 2021Fall armyworms can chew up an entire lawn in just a few short days making the timeline for treatment extremely sensitive. The after-effect comes in the form of a patchy looking, barren lawn that’s less than appealing. Fortunately, armyworms are known as “surface feeders” so they won’t harm the roots or crowns of your lawn’s grasses.

  • First, let’s be sure you know what you’re dealing with: Armyworms, which are moth larvae, are light green or tan in their earliest stages and become dark green or brown as they grow. Fully formed caterpillars are hairless, 1-½ to 2 inches long, and have green, yellow, or brown stripes running down their body, and a Y-shaped mark on their head.
