Sod Webworms are the larval or caterpillar stage of a small, tan moth often seen flying over the turf in the early evening during May through mid-fall.

Sod Webworms feed on the grass blades just above the soil line. The feeding defoliates the lawn where the Sod Webworms chew off the grass. They feed at night and hide in the thatch during the day. Presence of the larvae may not be noticed until significant damage has occured. Large numbers of tan moths on your lawn in the early evening may be evidence of Sod Webworm infestation.

Thatch maintenance at less that 3/4 inch thickness is helpful in decreasing the chance of Sod Webworm activity. Watering the lawn to prevent drought stress is also helpful.
