Armyworms are caterpillar larvae of the adult armyworm moth and are known to have devastating effects on both lawns and ornamentals. Armyworms get their name because they travel in small “armies”, eating everything in their path. Their presence is often undetected by homeowners because they are more active at night. Our lawn care technicians are adept at quickly spotting any indication of armyworm activity and will apply the best treatments to effectively eliminate them from your landscape. WHAT TO LOOK FOR: Look for an increase in the number of birds in your yard, as they eat the larvae. Also, look for brown spots on your lawn.
