This small family of about 6 dozen species has a few members that may be damaging to turf, the larvae feeding on the roots of the turf as well as on decaying plant materials. They will feed on most kinds of turf grass as well as on the roots of corn and a few other plants. The larva creates a vertical burrow in the soil and lives within this, emerging to sever blades of grass or surface roots and dragging these back into its burrow to eat. The burrow may be ¼ inch wide and up to 2 inches deep, with threads of silk lining the burrow and often extending up into the turf.
Very little is really known about these moths and their life history. Control should focus on the larvae and on products capable of contacting the larva either within its soil tube or as it emerges to remove foliage for consumption. Contact insecticide granules applied and watered in will be helpful as will contact insecticides sprayed onto the turf and left in place at night.
