I was told this Imidacloprid would kill them.
Criterion 75 WSP Systemic Insecticide is labeled to control leaf beetles and the active has been shown to be effective on Red Lily Beetles. It would be best applied before they are active in the area as it takes time to be translocated throughout the plant/trees. I did find a helpful guide from our our manufacturers Bonide as well. If they beetles are already active you would use something like Neem Oil or Spinosad.
