What’s Eating Your Lawn?
You’d be surprised.
During June, July, and early August, damage may occur as spotty patches of yellowing dead grass as a result of larval feeding. Injury often occurs adjacent to sidewalks and driveways but is not limited to these areas. It may also occur over the entire lawn. Masses of fine, sawdustlike frass (insect droppings) found at the crown of plants almost certainly identifies billbug damage.
