Thoroughly scout to identify the number, size, and circulation of fall armyworms and the condition of the turfgrass. Little armyworms (greenish in color) are much easier to control than caterpillars nearing their mature length of 1.5 to 2 inches.

Healthy turfgrass may endure low to moderate quantities of damage and can recover with watering and fertilization. See Healing below. Trim tall turfgrass before treatment to enhance insecticide coverage. Gather the clippings that accumulate on the surface. Irrigate gently several hours before treatment to increase larval activity on the soil surface.

See Table 1. Pyrethroid resistance has been reported in other parts of the country. If there is no fast control of fall armyworms after applying a pyrethroid, consider using a different class of insecticide, or hire a yard care business to apply a chlorantraniliprole or tetraniliprole substance. Azadirachtin insecticides (Neem oil) can supply control of little larvae and are certified natural.
