Moths lay clusters of eggs on grass blades, lawn furniture, white or light
colored walls and other objects near lawns. Caterpillars hatch and begin to feed
on the turf. Damaged turf appears ragged with individual blades showing signs of
chewing damage. When numerous, they may devour the grass down to the ground.
Caterpillars pupate in the soil. The moths emerge within a couple of weeks. They
are active mainly at night. There are three to six generations a year. As with
sod webworms, time insecticide applications to control armyworms during the
early evening when caterpillars are feeding on the surface of the turf.
Kill armyworms (army worms) with Acephate.
