Rose Chafer Infestation, what to do?

I have zillions of these destructive buggers on my apple trees. Only thing I have found that is supposed to kill them is Carbaryl, so I have applied Sevindust. Problem is that we are geting rain about every other day and most of it gets washed off. Of course the bugs don't mind the rain. I've got about 100 trees and can't take 2 hrs a day to squish all the bugs. Any ideas on a better control plan?

If you're going to use Sevin, don't use the dust, use the liquid concentrate and add a spreader/sticker.

Very hard to control this pest. I had major infestations for years. until this year. I sprayed BT on the ground and it appears to have killed the grubs for this year's batch as well as other beetles.

In other years, when the adults were active, I found insecticidal soap was the only effective option. They are very resistant to any type of pesticide.

If your still out there, 100 apple tree's is a huge number to hand pick. The university of Michigan developed the white chafer trap that you may have heard about. Chafers seems to run in cycles and have NO Natural predator's. I would recommend calling the U.n Mich. ext service and asking about a IPM (integrated pest management) plan. You have a sizable investment there to protect. Surround is available from several sources. I use garden alive. There's also several products like "grub ex". Traps/surround/floating row cover dividers and grub ex followed by beneficial insects may help. I still would consult with my local extension service as well.
