Don't Let Sod Webworms Take Over Your Jacksonville Yard This Summer
July 20, 2022 - sod webworms
Sod webworms are invasive lawn caterpillars that can cause significant damage to your turf grass. You may spot groups of pale-brown moths on warm evenings flying over your lawn grass. The larvae of this webworm moth feed on turf grass, chewing off the blades just above the crown.
The injured blades coalesce into big, brown patches before drying out as the infestation grows. You can easily mistake the brown turf with pet urine damage or drought stress. Pest control in Jacksonville can help you target and eliminate the tiny pests before they damage your lawn.
Sod Webworms In Home Lawns
The sod webworm, sometimes identified as the fall webworm moth caterpillar, is a lawn pest that invades your lawn between May to July and later during fall. At dusk, the adult moths fly over the grass, laying eggs on the thatch and blade surfaces. The eggs hatch within 7-10 days, releasing larvae that begin feeding on the grass.
The larvae are tiny caterpillars, about 3/4-inch long when fully grown. The caterpillars are light-green to brown, with parallel spots lined across the body. Adult moths are tan with snout-like projections.
Typically, the sod webworm larvae feed at night on foliage and can be observed crawling to the thatch layer during the day, where they spin silken webs in which they hide. Contact a residential pest control expert immediately if you notice the adult moths dashing over your lawn.
