- Immature – Similar to white grubs. Main difference being billbugs lack legs.
- Adult – Dark gray to black beetles with long snouts.
Damaging Stage: Larval Stage
Damaging Period: Not often seen until late in the year. Usually after a drought.
Optimum Control Period: Early summer
Damage & Signs of Activity: When the turf is pulled it breaks off easily at the crown. A sawdust like material is often visible in the root zone. Damaged turf appears as spotty patches of yellow or dead grass.
- Surface Insecticide Treatment – This treatment is recommended in the late spring/early summer and is meant to control adult billbugs before they are able to lay their eggs.
- Aeration with seeding or sodding may be required to repair damaged areas. A perennial rye grass seed is recommended as it appears to have the highest resistance to billbugs.
