Katy, TX (September 22, 2016) The Harris County Cooperative Extension has leased information about the sod webworms that seem to be causing extensive damage to St. Augustine grass in the Houston area.

Sod webworm larvae feed primarily at night and prefer areas in lawns that are hot and dry during daylight hours. Lawn damage occurs as the larvae chew off grass blades and retreat into their silken tunnels to consume the foliage. Lawns are particularly susceptible during July and August when the temperatures are hot and lawns are not growing vigorously.
