Lawn Moths/Sod Webworms

In our area, during summer months it is not uncommon to see the little white moths darting about a foot or two above the turf – especially in the shady areas and at night. Theses lawn moths do NO damage to your lawn – yes they are a nuisance but they absolutely do no damage to the lawn. But that is only half of the story.

The moths are laying eggs – eggs that hatch out into little caterpillars. These small caterpillars, called sod webworms, feed on the turf grass blades . According to Wikipedia: The Sod Webworm, ... is distributed practically worldwide, with approximately 100 species recognized in the United States alone. In sufficient numbers they can defoliate a lawn (eat all the leaves).
