While bermudagrass usually can recover from an attack, surviving a fall armyworm invasion is iffy for tall fescue.

Identifying Fall Armyworms

Adult moths are ash-gray and about 1 12-inches wide.

The moths are active at night and may be seen near porch lights.

Once the female moth lays eggs, the masses hatch in a few days, depending on temperature.

You may even hear their munching!

This may indicate that theyre feeding on the caterpillars, so inspect your turf, says Waltz.
