Billbugs are pests of turfgrass that can damage lawns throughout summer. Adult Billbugs are tiny weevils, about 1/3-inch long. They have a distinctive downward-sloping snout, and two club-shaped antenna on their head. However, it is the white, legless Billbug Grub, or larvae, that does the most damage to lawns.

Damage From Billbugs

Adults Billbugs lay eggs in holes they've chewed in grass stems. The larvae further damage the lawn by feeding on the grass stems and literally chewing off the roots of the turf. This results in expanding brown or dead patches in the lawn.

Where Billbugs are Found Geographically

Billbugs are common throughout the United States, excluding Southern Florida.
