Pest
Sod Webworms
Sod webworms are the caterpillar stage of small tan moths. They feed on grass blades at night, chewing notches and eventually shearing the lawn down to brown stubble. In Central Florida, peak damage occurs from late summer through fall.
Signs of sod webworms
- Notched, chewed grass blades
- Small tan moths flying up when you walk across the lawn
- Brown, closely-cropped patches in otherwise healthy turf
- Birds and wasps feeding heavily on the lawn
Damage
A heavy webworm infestation can shear a healthy lawn down to the runners in a matter of days. Damage typically appears first in stressed or sunny areas and spreads.
Treatment
A targeted insecticide application at the right life-cycle stage is highly effective. Healthy, well-fertilized turf recovers quickly once the population is knocked down.
