Sod webworms live in the thatch part of your grass, just above the soil. There they spin a light webbing and feed on the undersides of leaves. Damage, at first, appears as small, ragged brown spots in the turf. As feeding continues, these areas become larger and may join other large, dead patches of grass. Lawn damage occurs when webworms are at their larvae stage. During this time, they will typically attack most turfgrasses, including bluegrass, bentgrass, and tall and fine-leaf fescues. This type of destruction is most prevalent in areas that receive plenty of direct sunlight or south-facing slopes. For webworms, heavily shaded areas are not as desirable as eating ground, which means these areas are seldom attacked. Feeding damage frequently goes unnoticed during periods of drought, as the grass will typically look yellowish or brown naturally. Nevertheless, damage is still happening and you most likely won’t notice until it is too late.

Sod Webworms Damage Your Lawn

Sod webworm larvae damage often is observed as brown patches up to the size of a baseball on your lawn. In some instances, the brown patches are punctured with pencil-sized holes as a result of birds searching for the webworm burrows. The most severe damage usually occurs in July and August, while webworms are at their peak population. As webworm larvae continue to grow and feed, your lawn’s brown areas will continue to enlarge and affect the overall aesthetic of your home.
