The Iowa State University Extension Service is receiving more reports of a pest that’s damaging hay fields, pastures and even some lawns. Gentry Sorenson, an I-S-U Extension field agronomist says the fall armyworm can grow to be up to an inch and a half long. Sorenson says farmers can use an insecticide if the bugs are causing a lot of damage.

The bug is known to feed on crops like rye, wheat and oats as well as rice and various grasses.
