Fall Armyworms

Fall armyworms are actually the larval stage of a moth. These small, light-colored caterpillars with dark heads will eat many types of grassy weeds and lawn grasses, including bermudagrass. They become active in late summer and early fall. They rarely kill lawns, but can do damage. Eradication with a special lawn caterpillar pesticide is most effective when used early, when the armyworms are still small and green.
