Answer: I can't tell what kinds of beetles are in your tree without seeing them. I'd suggest collecting a few and taking them to your extension office for identification and control strategies. It may be that you can apply a grub killer such as Merit or Grubex to your soil to keep next year's generation from turning into adults. Contact Rutger's Cooperative Extension office, 621 Eagle Rock Ave, Roseland, NJ 07068-1501
(973) 228-3179 for help with identification of the beetles.
