Richard Hentschel, host of Green Side Up talks about two major lawn insects, Grubs and Webworms.

They differ in where they feed and live. Grubs live in the soil below the thatch layer and Webworms live within the thatch. Our populations of Japanese beetle larvae are far lower than expected due to the 2013 winter temperatures, so damage may not show at all in the lawn. Sod webworms come under attack by bird feeding and a fungal disease that attack the larvae stage. This year a treatament may not be warranted.
