If you detect a problem, try to assess the severity of the damage as well as the age/size and population of the larvae. Spraying with an insecticide is expensive and may not be necessary (or too late). The best time to look for the larvae is very early in the morning or just before dark. Armyworm larvae tend to stay near the soil surface during the day when it is hot and feed at night. For more information refer to the links and factsheets below:
