Advice on June Bugs/Japanese Beetles

I called into the morning show on the Sirius Martha Stewart channel to speak to Andrew Beckman http://www.marthastewart.com/page.jhtml?type=learn-cat&id=cat20863 about the beetle issues and the chemical v. milky spore treatment.

I got some contradictory advise to what I have received in the past:
I explained to him that I ran into an extension agent who told me that there was not scientific evidence that milky spore actually works. After the explanation I asked what his take was and he stated that he recommends the milky spore route along with praying. (Why would I need to pray if it works?) When asked about granuals v. powder distribution of milky spore; he commented that he thinks the granuals give better coverage. He also states that you only have to do the milky spore treatment for one year with the granuals (although the directions on the milky spore packaging states 2 years).

So without a clear cut way to handle these creatures, here is the current plan:
August 15, 2006: put down chemicals to kill the grubs laid this year. Clear turf for 2007 gardening. (Never did this in 06)
Spring, Summer and Fall 2007: treat with milky spore granuals to kill grub eggs for 2008 gardening.
