Sod Webworm Control in Your Lawn

Herpetogramma licarsisalis

Sod Webworms are the larvae (caterpillars) of moths (Herpetogramma licarsisalis) native to Australia, tropical Asia, central and northern Africa, and some Pacific Islands. Over recent decades Sod Webworm has become an established pest in Hawaii, northern New Zealand, and parts of Europe.

In Australia Sod Webworm is found throughout Queensland, in NSW as far south as Batemans Bay, and in the top end of the Northern Territory.

Sod Webworm was once viewed as a sporadic pest of pasture and public turfed areas but is now considered a serious pest of warm-season turf grasses especially during the warmer months of January to April. It is the larvae (caterpillars) which cause all the damage. The adult moths are harmless nectar feeders, and may be drawn to outside lights at night.
