How to Identify and Treat Armyworms

Armyworms, the larvae of a moth, can be identified by a series of stripes down the length of their bodies. The caterpillars are light green or tan in their early growth stage, becoming dark green or brown as they mature. They primarily eat grass blades, and large infestations can completely defoliate a lawn in just a few days. Arbor-Nomics’ insecticide is effective against armyworms at all stages of their development.
