There have been many reports of egg masses appearing on everything outside. The department of Entomology has determined that these are fall armyworm masses. “They’re like a caterpillar, but they feed in a row. So as they march across your lawn, they’re feeding on the turf on the grass. They will definitely eat it down to nubs,” says Hardin County Extension Agent Amy Aldenderfer. These worms can create a lot of damage and are easiest to control when they are small.
