What does sod webworm damage look like?

Sod webworm damage is characterized primarily by small dead spots or areas within the turf. These small dead spots occur due to the larvae of the sod webworm feeding on the grass blades, which typically leaves behind irregular patches rather than large bare areas.

The feeding pattern of the larvae results in scattered, localized patches of dead grass, often making the damage appear spotty rather than widespread. This differentiation is essential for identifying sod webworm damage compared to other pests or stress factors that may cause larger areas of grass to die off or discolor. Understanding this distinctive pattern helps in diagnosing the problem accurately and determining the appropriate control measures for the infestation.
