Cutworm
CUTWORM/SOD WEBWORM
WHAT ARE CUTWORMS? Cutworms are large, plump dull coloured grayish green and brown larvae which viciously chew on grass plants. They live on the soil surface or in the thatch layer. During the day they burrow into vertical holes to hide. When nightfall arrives they emerge from their burrowed hole and feed at the rim of the hole. Stems, leaves and roots of the grass plants may be injured leaving yellowish brown dead patches with a hollow hole in the middle of the circle. The damage looks quite similar to symptoms of dryness and many homeowners mistakenly assume that the lawn requires only water to restore the lush appearance. Another symptom to watch for is birds- Starlings have a keen ability to locate cutworm larvae. When these birds return frequently to an area cutworm larvae may be present. CUTWORM LIFE CYCLE

SOD WEBWORM LIFE CYCLE
HOW CAN I TREAT FOR CUTWORM AND SOD WEBWORM? The best time to treat cutworm and sod webworm is when they are very young in June/July before severe damage occurs. By early fall they begin to transform into adults. In the adult stage they are very difficult to control. If you notice suspicious brown patches starting to appear in the lawn, DO NOT HESITATE!
