While CoreTect Tree & Shrub Tablets Insecticide could be used to treat around eucalyptus or other ornamental trees, we cannot be sure that it would correct an existing beetle infestation. Many bark beetles will hide under the bark where they are protected from topical sprays, but not deeply enough into the tree that they are affected by systemic treatments such as the CoreTect.
Beetles often infest trees that are already weed from disease, drought, or other issues, so be sure that you check for signs of stress in existing trees. You may consider reaching out to a Master Gardener in your area for assistance identifying the specific pest so that you can know how best to prevent future issues.

CoreTect Tree & Shrub Tablets Insecticide is labeled for Japanese Beetle adults on established trees, you would use 2-3 tablets per inch of trunk diameter or per foot of shrub height. It is not labeled for June bugs though and we are unable to find a systemic that could be used for the adults. Adonis 2F could be used for Japanese beetles adults and larvae (in turf), as well as Green June Beetles and larvae in the soil.
