FALL ARMYWORM:

Fall armyworm damage in turfgrass is very distinctive. Since armyworms cross the turf surface as a group, they create a noticeable line between damaged and undamaged turfgrass. Usually damaged areas will originate around a site where egg masses can be easily laid (signposts, buildings) and radiate outward. 

Damaged lawns can be treated, but we recommend applying insecticide as a preventative measure for better control.
