BEETLES, BEETLES, AND MORE BEETLES!!!

Can anyone help?! I live in Selinsgrove, PA and I love my gardens. This year has to be one of the worst I've seen for the infestation of Japanese Beetles. These little bastards have really got me pissed! All the planting, all the TLC, weeding, fertilizing, deadheading, pruning---it's a lot of work, but I love it. And now I'm sick. They are eating everything! I read some where not to put out traps because it will just attract more beetles! NO! I also have heard of milky spore, which is to be applied to the lawn to kill the grubs before they become beetles. Does this work? I am making a trip to the local nursery tomorrow to see if they have it. Please leave any helpful comments. Thanks and have a good day!
