White Grubs in Rose Bush Container in Hawaii: Identification and Organic Control

A Hawaii gardener finds white grubs while transplanting a rose bush. Initially thought they were grubs; later confirmed as white grubs (likely rose chafer or Japanese beetle larvae).

Expert Answer: Adult beetles emerge early summer—hand-pick or treat with spinosad (info). Soil larvae: nematodes or Milky Spore can work. Search "white grubs Hawaii" for local info.
