The beetle that knotches leaves or underground weevil.
Bayer Advanced Complete Insect Killer For Soil & Turf is only labeled for annual bluegrass weevil. You should hand remove any adult insects by searching the plants at night with a flashlight. Drop the active adults into a bucket of soapy water. For the juveniles you can help control them with a fast acting product such as Bonide Eight in One concentrate spray.
