An adult billbug is a black beetle (weevil) that has a "bill" or snout. The chewing mouthparts are at the end of the snout. Billbugs are found throughout Florida and have become more of a problem for Florida lawns in recent years. Zoysiagrass and bermudagrass are preferred hosts, and most damage occurs in fall and spring. If grass consistently wilts in an area of the turf despite proper irrigation, an infestation of root-feeding billbugs should be considered.
